Tips

Faulty electrical wiring is responsible for over 53,000 home fires annually. 

Some of the most common culprits of electrical fires are:

• Frayed chords
• Loose electrical connections
• Damaged wire insulation
• Overheated wires
• Rodent damage to wires
• Outdated electrical wiring, such as knock-and-tube wiring

Many homes in Northeastern Pennsylvania also have not adopted the latest National Electrical Code standards, which mandate that all kitchens, garages, crawl spaces, bathrooms, and laundry rooms install ground-fault circuit interrupters (GFCI). 

These devices are designed to shut off electricity to circuits once a ground fault occurs, preventing your electricity from arching or overheating the wiring. 

While most people associate electrical issues with older homes, any home can suffer from these issues. 

Fortunately, spotting these issues is often not as difficult as most people think. By conducting routine home inspections of your electrical system and learning the signs of electrical issues, you can diagnose problems in real time and make repairs to protect your home. 

Dangers of Fault Electrical Systems

It’s easy to address issues in your home when you can spot them with your eyes, whether it’s a leaky roof or a leaky pipe. However, faulty wiring and bad circuits are dangerous because they occur behind closed walls. 

If left unchecked, damaged wiring, short circuits, and even outdated wiring could lead to:

• Electrical Fires: Damaged or overloaded wiring is a leading cause of house fires. Wires that overheat can ignite insulation, wood framing, or nearby household items.
• Electrical Shock: Exposed wiring or improperly grounded circuits can deliver painful or even deadly electric shocks, especially in areas like kitchens, bathrooms, and basements where water is present.
• Appliance Damage: Faulty wiring can create voltage spikes or inconsistent current flow, which may damage sensitive electronics or shorten the lifespan of appliances.
• Increased Energy Bills: Poor electrical connections force your system to work harder, which can waste electricity and drive up your utility costs.

Even small issues like loose connections or frayed wires can spark major trouble if left unaddressed. In addition to identifying and correcting these issues, it’s also important to update your home’s electrical system to modern standards. With that said, let’s explore six common electrical issues found in older and newer homes alike.

6 Signs of Electrical Issues Within Your Home

If you discover any of these nine potential electrical issues, be sure to perform a home inspection as soon as possible. 

1. Flickering or Dimming Lights: In some cases, a flickering bulb could be the result of a loose bulb, but it could also be a sign that your electrical system is struggling to keep up. Faulty electrical circuits can occur over time for several reasons, including damaged wiring, overloaded circuits, or loose connections.  
2. Frequent Circuit Breaker Trips: Circuit breakers are designed to trip (shut off) when a circuit becomes overloaded or short circuits. While this may be common where huge appliances draw too much power from the same circuit, frequent circuit trips could indicate a deeper problem. 
3. Burning Smell or Discolored Outlets: If you ever notice a faint burning smell (especially one like melting plastic) near outlets, switches, or your breaker panel, stop and investigate immediately. This can indicate a serious problem that needs to be addressed immediately, lest you risk starting an electrical fire inside your home. 
4. Sparking Outlets or Switches: A small spark when plugging in a device isn’t always dangerous and can even be common. However, if outlets or switches spark frequently, produce large or loud sparks, or accompany the spark with a burning smell or smoke, it could indicate damaged wiring or a short circuit within the wall. 
5. Outlets or Switch Plates That Feel Warm: Outlets and switches that feel warm to the touch during use could indicate a serious electrical issue that needs to be resolved immediately. In most cases, this is due to an overheated wire that has melted the insulation. 
6. Rodent Damage: Rodents such as mice and squirrels love to chew on insulation and electrical wires, especially in attics, basements, and inside wall cavities. Chewed wiring from mice can lead to a whole host of issues, including exposed wires, sparks, and short circuits.

The Problem with Outdated Wiring

Outdated wiring is one of the most common home inspection issues found in Northeast Pennsylvania, specifically knob-and-tube and aluminum wiring. 

In the former instance, the issue with knob-and-tube wiring comes when new insulation is installed near exposed wires and connections. According to InterNACHI–the leading organization for home inspectors–”(Knob-and-tube) K&T wiring is designed to dissipate heat into free air, and insulation will disturb this process. Insulation around K&T wires will cause heat to build up, and this creates a fire hazard.”

Again, any type of wiring is subject to its own issues, which is why adding in additional controls is important for minimizing risks. 

Modernizing Your Electrical System

In addition to common electrical faults and issues, our home inspectors also frequently note common improvements homeowners should make to outlets when buying or selling a home.

For example, we will point out any two-pronged outlets we find that lack sufficient grounding, which are at greater risk for electrical shock and fires. 

We also recommend that all homes install ground-fault circuit interrupters in required areas by code, especially any room where water is present. 

These simple investments can make your home safer and reduce the risk of an electrical fire or accident. 

The Importance of Home Inspections for Outdated Electrical Systems

A professional home inspection can help you avoid serious injuries or repairs that can result from a faulty or outdated electrical system. We recommend a home inspection anytime you buy or sell a home in Northeast Pennsylvania or whenever one of the potential issues above has been spotted.

FAQs

Are older homes more at risk for electrical fires?

Yes. Older homes are more likely to have outdated wiring, worn insulation, ungrounded outlets, and electrical systems that weren’t designed to handle modern power demands — all of which increase the risk of electrical fires.

How often should I have my home’s electrical system inspected?

For homes over 30 years old, it’s wise to schedule an electrical inspection every few years — especially before major renovations, after purchasing a home, or if you notice any signs of trouble.

According to one survey, over 26% of Pennsylvania residents rely on private wells for drinking water in the commonwealth. 

Unlike public water utilities, which are cleaned with advanced filtration systems and disinfectants, well water is often unfiltered and not treated using any chemicals. 

One of the most important tasks of owning a private well is to conduct frequent water sample testing to protect your health and get informed of potential pathogens hiding in your water.

Since most properties with private well systems also rely on septic systems, a combination of water sample testing and septic inspections is especially important, as effluence from septic tanks is one of the most common causes of contamination. 

Learn more about why water sample testing is crucial for all homeowners in Pennsylvania, regardless of whether they get their water from a private well or public utility. 

What Is Water Sample Testing?

Water sample testing is the process of collecting and analyzing a sample of your drinking water to check for the presence of contaminants and assess overall water quality. 

Water samples are sent to a laboratory for testing to detect the presence of harmful bacteria, heavy metals, chemicals, and excess minerals — most of which can’t be seen, smelled, or tasted.

7 Benefits of Water Sample Testing in Northeast Pennsylvania

Water testing can provide early detection of any harmful substances lingering in your water supply or plumbing that can adversely impact your health and home. 

Here are seven reasons to get a water sample test in Northeast Pennsylvania. 

1. Protect Your Family’s Health

Well water contamination can occur from several sources, including runoff from melting snow, stormwater, and wastewater effluents.  

Unfortunately, contaminants like lead, arsenic, nitrates, bacteria, and even viruses can sneak into your water supply without any obvious signs, leading to chronic symptoms that include: 

• Gastrointestinal issues
• Developmental delays in children
• Reproductive problems
• Increased risk of cancer
  

However, well water is not the only water source that can become contaminated. While public water is required to meet certain regulatory standards, old pipes, filtration systems, and humidifiers can become contaminated and end up getting you sick. Getting routine water sample tests will help avoid these unknowns and protect your family’s health against possible toxic exposure. 

2. Well Water Isn’t Regulated Like City Water

Private well owners are entirely responsible for their well water management. The first step toward identifying problems associated with your well water is to perform a water sample test.

The EPA recommends well owners test their water at least once a year or more frequently if:

• You’ve had recent flooding or construction near your well
• You notice a change in taste, odor, or color
• A household member develops unexplained health issues
  

Sampling your well water is essential for catching bacteria, nitrates, and other naturally occurring or human-made contaminants early.

3. Aging Plumbing Can Introduce Contaminants

On the other hand, even if your city’s water system is modern and well-maintained, your home’s internal plumbing might not be. Homes built before the 1980s often contain lead pipes, solder, or fixtures that can leach lead and heavy metals into your drinking water. 

Lead is particularly dangerous for young children, infants, and pregnant women, and it often enters your water after treatment during its journey through aging pipes.

Remember that not all public water is maintained to the same standards, nor does it come from the same sources. Some water may be more acidic than others, which can accelerate the degradation of your pipes and water filtration systems.

4. Detect Hidden Chemical Contamination

If you are generally worried about your health and water quality, then a water sample test may be helpful in identifying many common chemicals found in public water, including:

• Pesticides and herbicides
• Industrial solvents
• PFAS (“forever chemicals”)
• Radon gas in groundwater
• VOCs (volatile organic compounds)
  

These contaminants can enter water supplies from agricultural runoff, manufacturing facilities, or household chemicals, impacting well water and public water systems alike. 

Long-term exposure to these chemicals can be harmful, and the only way to detect them is through periodic testing.

5. Protect Your Appliances and Plumbing

Beyond electricity and gas, water is by far the most ubiquitous and important resource used in homes today. In addition to drinking water, your water is also used for bathing, washing dishes, and washing clothes. 

Therefore, poor water quality doesn’t just affect your health — it also impacts your plumbing system, fixtures, and appliances. 

For example, high mineral content (commonly known as “hard water”) can cause limescale buildup in pipes, water heaters, and washing machines and reduce the lifespan of these appliances. 

Water sample tests provide a detailed overview of your water’s mineral content so that you can adjust your filtration system to protect your plumbing and appliances. 

6. Test Before Buying or Selling a Home

If you’re buying a new home, especially one with a private well, a water test should be part of your inspection process. 

Not only is a water sample test essential for your health and safety, but it can also point to possible issues with your septic system and plumbing that will require future repairs. 

7. Gain Peace of Mind

While many people would prefer to avoid another expense in today’s economy, water sample testing is quick and affordable and can save you lots of money on future repairs or health issues over time.

Most importantly, it can help answer a lot of unknowns when it comes to your drinking water and health. If you are suffering from unexplained medical ailments, then a water sample test can be an important step to fixing any unknown issues.

When Should You Test Your Water?

If you have private well water, we recommend testing your water at least every one to two years to ensure that there are no changes to the water content due to runoff or effluents. 

For individuals with public drinking water, this can be done at a longer interval, like every two to five years. 

With that said, you should consider testing your water if:

• You’re buying or selling a property.
• You rely on a private well.
• You live in an older home.
• You notice changes in water taste, color, or smell.
• You’ve recently completed plumbing repairs.
• You live near farms, factories, or known contamination sites.
• You’re pregnant, have young children, or have a compromised immune system.
  

For municipal water, review your local water utility’s annual Consumer Confidence Report (CCR), but remember: that report covers the water as it leaves the treatment plant — not after it’s traveled through miles of pipes to your home.

FAQs

Why is water quality important?

Water quality directly impacts your health, home, and overall well-being. Contaminated water can carry harmful bacteria, chemicals, and heavy metals that may cause both short-term illnesses and long-term health issues. Beyond health, poor water quality can also damage plumbing systems, stain fixtures, reduce appliance lifespans, and affect the taste and smell of your drinking water. Testing ensures you’re aware of any risks and can take action to protect your household.

How often should I test my drinking water?

If you use a private well, the EPA recommends testing at least once a year for bacteria, nitrates, and other common contaminants. If you’re on city water, review your local water utility’s annual report, but you may still want to test your home’s water if you notice changes in taste, smell, or color — or if you live in an older home with aging pipes.

What should I do if my water test results show contamination?

Solutions depend on the type of contaminant. In many cases, installing a certified filtration system, repairing plumbing, disinfecting your well, or using bottled water for drinking and cooking can solve the problem. If contamination is severe, consult with a water treatment professional or local health department for guidance.

The charm of older homes in our great area will never cease to amaze us. But underneath that old architecture, a dark secret may lie.

Mold, mildew, lead paint, and other VOCs are common issues found in many older homes across Northeast Pennsylvania. 

While some laws and disclosures have attempted to cut down on the presence of lead paint and asbestos, particularly older homes may still have these dangerous substances within them. 

Poor ventilation found in attics, bathrooms, and kitchens in older homes also creates the perfect environment for mold. And we don’t need to mention the harm that basement flooding can do to air quality in a home. 

Professional air quality testing is a crucial step in identifying and mitigating potential hazards in an older home. Whether you’re living in a historic property— or considering purchasing or selling one— here are nine reasons why you should invest in air quality testing.

What Is an Air Quality Test?

An air quality test is a professional assessment that measures the presence of pollutants, allergens, and harmful substances in indoor air. This testing helps identify contaminants such as mold spores, volatile organic compounds (VOCs), carbon monoxide, asbestos fibers, and dust particles. 

Professionals use specialized equipment to collect air samples and analyze them for harmful substances that could impact respiratory health, cause allergies, or lead to long-term illnesses. 

The results provide homeowners with a clear understanding of potential air quality issues and recommendations for improving indoor air conditions.

Air quality tests are particularly important for older homes, where outdated building materials, aging ventilation systems, and hidden moisture issues can contribute to poor indoor air. 

Professional air quality testing can detect problems that aren’t visible to the naked eye, allowing homeowners to take proactive measures to improve air circulation, remove contaminants, and create a healthier living environment.

6 Reasons to Get an Air Quality Test

Getting a professional air quality test is essential for your health and can also protect your home by identifying potential issues that may be hidden. 

1. Identifying Hidden Mold and Mildew

Moisture intrusion and poor ventilation can lead to the presence of mold and mildew, which may be hidden from plain view and remain undetected for years. 

Unfortunately, older homes are more likely to have moisture issues due to aging plumbing, roof leaks, or poor ventilation. This excess moisture can lead to mold and mildew growth, triggering allergies and respiratory issues. 

Professional air quality testing can detect mold spores in the air, even if visible mold isn’t present. Identifying and addressing mold early can prevent costly remediation and health problems and point to potential leaks or moisture issues that may cause other problems in your home. 

2. Detecting Asbestos Fibers

Many homes built before the 1980s contain asbestos fibers in their insulation, ceiling tiles, or siding materials. While asbestos isn’t automatically toxic on its own, when disturbed, it can become airborne and cause severe lung diseases.

Unfortunately, many people may be unaware they have asbestos in their homes or fail to disclose it when selling them. 

Air quality testing can determine if asbestos fibers are present, helping homeowners take necessary precautions before renovations or repairs.

3. Checking for Lead Dust Contamination

Lead-based paint was widely used in homes before it was banned in 1978, but can still be found in several homes in Pennsylvania today. According to the EPA, 69% of homes built between 1940 and 1969 are likely to contain lead-based paint, and 87% of those built before 1940 are also likely to contain lead-based paint. 

Lead-based paint can cause several harmful health effects, including:

• Developmental delays in children
• Neurological issues
• Kidney and cardiovascular problems

Professional air testing can provide extra assurance by identifying harmful lead contaminants, allowing you to remove them before occupying or buying a home. 

4. Identifying Carbon Monoxide Risks

Old homes often have outdated heating systems, fireplaces, or gas appliances that can produce carbon monoxide (CO). Because CO is an odorless and deadly gas, undetected leaks pose a severe health risk. Symptoms of CO poisoning include:

• Dizziness and headaches
• Nausea
• Confusion and fatigue

Air quality testing can detect unsafe levels of carbon monoxide beyond home testing kits that ensure your home’s ventilation systems are functioning properly.

5. Checking for Volatile Organic Compounds (VOCs)

Many old homes contain building materials, adhesives, and finishes that release volatile organic compounds (VOCs) into the air and can lead to respiratory issues. Some common sources include oil-based paints, old carpeting, adhesives, and stored chemicals.

An air quality test can identify high VOC concentrations that may be impacting your long-term health.  

6. Radon Detection

Radon is a silent gas that has been linked to cancer development and other detrimental health effects. Unfortunately, 40% of homes in Pennsylvania have been linked to unsafe levels of radon exposure. 

Conducting a radon test can be a lifesaver. Eliminating radon often requires a radon mitigation system installed in your basement or the lowest level of your home. 

7. Testing for Poor Ventilation and Stale Air

Finally, we recommend air quality testing for older homes that have poor ventilation or older HVAC systems. Poor ventilation can lead to increased humidity, lingering odors, mold, dust, and much more. 

A professional assessment can determine if your home needs better airflow solutions, such as upgraded ventilation systems or air purifiers.

How Much Does an Air Quality Test Cost?

The national average for an air quality test costs around $420, though this depends heavily on several factors:

• Home Size: The size of the home and amount of rooms or surfaces that need to be tested will greatly influence pricing.
• Hazards Tested: Prices vary between different types of air quality tests, with mold and radon testing trending on the higher side of the spectrum. 

To get the most accurate air quality testing for your home, contact the experts at Mountain to Valley Home Inspections. 

FAQs

Why is air quality testing important in an old house?

Older homes are more likely to have air quality issues due to outdated materials, aging ventilation systems, moisture problems, and hidden pollutants like asbestos or lead dust. Testing helps ensure a safe and healthy indoor environment.

What are common indoor air pollutants found in old homes?

Common pollutants include mold spores, asbestos fibers, lead dust, radon gas, carbon monoxide, volatile organic compounds (VOCs), pet dander, and dust mites.

Can I use a DIY air quality test instead of hiring a professional?

DIY kits are available, but they often provide limited results. Professional testing offers more accurate and detailed analysis, especially for hazardous substances like asbestos, radon, and mold.

The foundation provides structural integrity for the rest of the home, yet many homeowners tend to neglect it, especially when it comes to easy fixes. 

Whether it’s reinforcing a mortar wall or fixing your downspouts to drain further away from your home, you’d be surprised how such little fixes can add decades to your foundation.

Finding foundation issues can be uncomfortable for homeowners as repairs can be among some of the most expensive homeowners will make. 

Foundation issues not only point to other issues within the home but could threaten to lead to additional issues, such as cracked walls, separated frame members, and sloping floors. 

Foundation inspections are often included in home inspection reports when buying or selling a home. Still, getting a separate foundation inspection may be ideal if you suspect issues in your current home. 

If you are concerned about potential foundation issues, read more to learn about the importance of a foundation inspection and whether you need one. 

What Is a Foundation Inspection?

A foundation inspection assesses the stability and condition of a home’s foundation, identifying common issues based on the construction of the foundation and local environmental concerns. 

Due to the rapid freeze-thaw cycles throughout the winter in the Northeast and the general amount of rain in the Scranton area, foundation issues are very common. From shifting soil to water intrusion, it’s not uncommon for residents to experience heavy volumes of water in their basement or crawl space during extreme weather events. 

Consider that many older homes weren’t built to the standards we expect today and often don’t provide enough room for drainage for downspouts, leading to water buildup around the foundation. 

A foundation inspection identifies common issues associated with foundations, as well as causes and fixes that can improve the longevity of the foundation. Keep in mind that foundation inspections aren’t just limited to the actual foundation but encompass the exterior foundation walls, basement, crawl space, and even the walls inside your home. 

Common Types of Foundations in Northeast Pennsylvania

Considering the foundation type and some exterior factors, your foundation inspector can better determine what to look for in an inspection. In Northeast Pennsylvania, there are generally five common foundation types, which vary based on when and where the home was built. 

• Basement Foundations: The most common foundation structure found locally. This foundation typically features poured-on concrete or stone walls (pre-1930s) that may be subject to cracks or water intrusion due to hydrostatic pressure or gaps in the exterior walls. 

• Crawl Space Foundation: Also known as a stem-walled foundation, this foundation is made of the same materials and is slightly elevated off of the ground to prevent contact with moisture. However, crawl spaces are often subject to mold and the foundation floors can sink if the soil is not properly compacted. 

• Slab On Grade Foundation: Often found in mobile homes, this type of foundation offers no additional living space and is cheap to build. These foundations can often crack due to direct contact with the ground and any surrounding water. 
• Pier and Beam: Found in flood-prone areas, such as near the Susquehanna River, this type of foundation is similar to a stem-walled foundation and can suffer from the same issues. 

7 Things Experts Look For During a Foundation Inspection

Foundation issues are common in both older and newer homes in the area, but they are not automatically causes for concern. In our experience, the most common foundation issues we find are:

1. Foundation Cracks and Gaps

Foundation cracks can be a sign of water intrusion, increased hydrostatic pressure, or the wearing away of foundation materials. However, not all cracks are created equal, and understanding which type of crack you have will determine how serious the issue is. 

• Vertical Cracks: Often caused by natural settling, these cracks are fairly common and not typically cause for concern.
• Horizontal Cracks: A sign of serious pressure against the foundation, these cracks indicate separation of the foundation materials and often result from soil expansion or poor compaction. 
• Stair-Step Cracks: Common in brick or block foundations, these cracks can indicate movement or shifting and should be considered fairly worrisome.

Your inspector will also check for widening cracks, which may suggest ongoing movement requiring immediate attention.

2. Uneven or Sloping Floors

An uneven floor indicates foundation movement and can be observed all throughout the house. Inspectors use leveling tools to measure slope variations on different floors to determine if the foundation is shifting or sinking. Freeze-thaw cycles often contribute to this movement by allowing the surrounding soil to expand and contract, thus shifting the foundation.

3. Sticking Doors and Windows

Another key sign of foundation issues can be observed elsewhere in your home around the window and door frames. In extreme cases, visible gaps in the door or window frame will prevent these parts from latching or moving correctly.  

4. Bowing or Leaning Walls

An extreme and obvious sign of a foundation issue is bowing or bulging foundation walls, which can indicate extreme soil pressure or water buildup around the foundation. 

Hydrostatic pressure from excessive moisture can push walls inward, leading to cracks or tilted walls.

5. Water Intrusion and Drainage Issues

While some water intrusion may be common for residents in flood-prone areas, it’s a major source of concern. A foundation inspection will take into consideration past water intrusion to determine if any cracks or issues exist. 

Some signs of water intrusion in a basement or crawl space include water stains, mold, and excess humidity. 

6. Exterior Foundation Exposure and Soil Conditions

When inspecting the outside, an inspector will note any obvious issues, such as visible cracks or gaps in the foundation. They might also inspect the soil surrounding the foundation, taking into consideration any tree roots that may impact it or downspouts that drain directly into it. 

7. Chimney and Brickwork Condition

Finally, another major sign of foundation settling and poor stability could be a leaning chimney or cracked brickwork. Your inspector will evaluate whether chimney shifts are related to general foundation issues or independent settling.

When Should You Get a Foundation Inspection?

A foundation inspection is an important part of home ownership. It should be done every five to ten years or at the first sign of an issue, such as visible cracks or settling elsewhere in the house.

A foundation inspection is also necessary when buying or selling a house. It can help avoid expensive repairs and reassure others that the home is in good condition. 

Costs of Foundation Inspections in Northeast Pennsylvania

According to This Old House, foundation inspections cost between $300 and $1000. However, the cost will depend on the size of the home, its location, and the type of foundation. Basement and crawl space foundations cost slightly more than slab foundations.

FAQs

What Are Common Causes of Foundation Issues in Northeast Pennsylvania?

Foundation issues can result from several environmental factors and homeowner neglect. These include:

• Freeze-thaw cycles causing soil expansion and contraction
• Poor drainage leading to water damage
• Tree roots disturbing the foundation
• Natural settling over time

Can I Perform a DIY Foundation Inspection?

While homeowners can spot visible cracks or moisture issues, a professional inspection is essential for detecting deeper structural problems.

What Are Signs that I Need Foundation Repair?

• Large or widening foundation cracks
• Bowing basement walls
• Doors and windows that no longer close properly
• Persistent water damage in the basement or crawl space

Mold can be extremely difficult to spot, and many people go through months of allergy-like symptoms before identifying the cause. This is not only a health concern but can cost you much in time and money if you’re going to sell your home. 

Mold, often found behind walls, ceilings, and floors, typically requires a separate and specialized inspection to identify and remediate. Unfortunately, remediation costs can total thousands and greatly diminish a home’s value.

Mold is often a symptom of deeper problems in your home, such as water leaks, excess humidity, and poor ventilation. Due to the rapid temperature shifts experienced in Pennsylvania, anything from cracked shingles to a frozen pipe can lead to water intrusion and subsequent mold. 

Stopping mold requires understanding its typical causes and fixing structural issues within your home that contribute to it. 

This guide will discuss everything you need to know about mold prevention, including common causes, prevention tips, and the importance of routine inspections. 

The Dangers of Mold Exposure

Mold exposure can lead to various health issues, especially for individuals with allergies, asthma, or weakened immune systems. Common symptoms include coughing, sneezing, skin irritation, and eye discomfort. 

Prolonged exposure to mold spores can even cause respiratory problems and, in severe cases, lead to chronic lung conditions. However, not all types of mold are the same, so it’s essential to identify the specific strain within your home. 

Certain types of mold, such as Stachybotrys chartarum (black mold), produce mycotoxins that may contribute to neurological symptoms and other serious health concerns. 

Preventing mold growth through proper ventilation, moisture control, and timely remediation is essential for maintaining a safe indoor environment.

Signs You Have Mold in Your Home

Again, mold can be tricky to spot and often requires a total home inspection, including behind existing surfaces, to identify mold. 

However, there may be some clues or hints of mold hiding right behind your walls that you may not be aware of. 

• Musty Odor – A persistent, earthy, or damp smell, especially in basements, bathrooms, or other humid areas, could indicate mold growth, especially if there is no other explanation. 
• Water Damage or Stains – Discoloration on walls, ceilings, or floors often indicate hidden mold growth or the possibility of mold.
• Peeling or Bubbling Paint/Wallpaper – Moisture behind walls can cause paint or wallpaper to deteriorate, indicating that mold is hiding underneath.
• Warped or Soft Flooring – Mold and moisture damage can make wood floors buckle or carpets feel damp, even if existing water damage has been cleaned up.
• Increased Allergy Symptoms – Sneezing, coughing, itchy eyes, or worsened asthma indoors may indicate mold spores in the air.
• Persistent Respiratory Issues – Chronic coughing, congestion, or breathing difficulties without a clear cause are often a clear and dangerous sign of mold.
• Excess Humidity or Condensation – Constant dampness, condensation on windows, or high indoor humidity create ideal mold conditions, which should warrant inspection. 
• Visible Mold Growth – Patches of black, green, white, or brown mold on walls, ceilings, or other surfaces.

If you do spot any of the following signs of mold in your home, reach out to a local home inspection company to get a mold inspection immediately. 

The Importance of Mold Inspections

A professional mold inspection is the only way to detect and address mold issues before they become severe. 

A mold inspection goes beyond a traditional home inspection. It uses advanced tools and techniques, such as thermal imaging cameras and moisture meters, to detect areas where mold is bound to be present and spot any strains hidden behind structures. 

The benefits of getting a mold inspection are essential for homeowners or house hunters. 

• Early Detection – Identifies mold problems before they spread and lead to structural damage.
• Health Protection – Ensures indoor air quality remains safe for you and your family.
• Accurate Identification – Determines the type of mold present and the best course of action for removal.
• Prevention of Future Growth – Experts provide recommendations to prevent mold from returning.

Furthermore, a mold inspection company may be able to identify the source of moisture intrusion, such as a leaking roof or pipe that needs to be repaired to prevent future mold growth. 

7 Ways to Stop and Prevent Mold in Your Home

Given these dangers, homeowners need to practice proper home maintenance to prevent future mold growth. Stopping mold growth also helps protect the structural integrity of your home and prevent moisture intrusion, which can lead to a host of additional problems. 

1. Control Indoor Humidity Levels

Mold thrives in humid environments and the humid summers can be the perfect breeding grounds for mold if you are not careful. Typically, basements and attics with little ventilation suffer the most from excess humidity and mold growth. 

To keep mold at bay, maintain indoor humidity levels between 30-50% using dehumidifiers, air conditioners, and proper ventilation, such as opening a window.

2. Improve Ventilation

Proper airflow prevents excess moisture buildup. Think about what areas of the home are the most subject to moisture and humidity (i.e., bathrooms, kitchens, laundry rooms). Consider installing exhaust fans or keeping windows open while showering or cooking to prevent moisture buildup. 

3. Fix Leaks Immediately

Leaky pipes, roofs, or windows create moisture-prone areas perfect for mold growth. If you’ve had a past leak, be sure to get a mold inspection to determine if any mold has developed underneath the surface. Often, homeowners will vacuum the water and dry the area but won’t take any steps to clean up any mold that may have developed. 

4. Dry Wet Areas Promptly

If you spot any areas of your home where there is water buildup, such as on the edge of a bathtub or a window sill after a storm, dry and vacuum the area immediately. This can prevent mold and damage to these areas, which are extremely common within the home. 

5. Use Mold-Resistant Products

When renovating or building, opt for mold-resistant drywall, paints, and insulation materials to minimize the risk of mold growth in the future. This can help prevent future mold growth and make remediation and prevention easier. 

6. Clean and Maintain Gutters

Clogged gutters can cause water to overflow and seep into your home’s foundation or walls. They can also lead to roof damage, which can invite leaks. Therefore winterizing your gutters is an essential part of fall home maintenance and can help prevent moisture intrusion in your home.

7. Monitor and Maintain HVAC Systems

Your heating and cooling system is another common but overlooked source of mold exposure in the home. It’s also one of the most dangerous as it filters in air throughout your home. Be sure to change filters regularly and schedule routine HVAC inspections to prevent mold growth within ducts and vents.

FAQs

How quickly does mold grow after a water leak?

Mold can start growing within 24-48 hours after moisture exposure if conditions are favorable.

Do air purifiers help with mold?

Air purifiers with HEPA filters can help remove airborne mold spores, but they do not eliminate mold growth on surfaces.

Can I remove mold myself, or do I need a professional?

Small mold patches (under 10 square feet) can often be cleaned with household solutions like vinegar, bleach, or hydrogen peroxide. Larger infestations require professional remediation.

Chances are, if you’re buying a home with a bad foundation, more problems may be hiding under the surface for future repairs. 

Unfortunately, foundation repair is among the most expensive home repairs and, in extreme cases, can even lead to the demolition of the home. 

While some natural settling will occur over time, neglect from homeowners or extreme environmental conditions can damage a foundation and disrupt a home’s equilibrium. 

In most cases, foundation issues can be caught early and fixed without significant repairs. This reiterates the importance of getting a qualified home inspection and periodically checking your foundation for issues. 

Common Types of Foundations in Northeast Pennsylvania

The foundation type in your home often reflects the era in which it was built, local building codes, and environmental conditions. 

In Northeast Pennsylvania, you can find a variety of different foundation types, from stone foundations built over a century ago to modern concrete slab foundations, with the most common being:

1. Basement Foundations: Found in a majority of older and modern homes alike, basements provide additional storage or living space. Foundation walls can be composed of several materials, from concrete to stone. While most basement foundations are sturdy, they are prone to moisture issues due to Northeast Pennsylvania’s rainy seasons and heavy snowmelt.
2. Crawl Space Foundations: Homes with elevated foundations–often found along the Susquehanna River—provide a buffer between the home and the ground, preventing flooding from excess water flow. These foundations are very sturdy but require more maintenance than other foundations.  
3. Slab-on-Grade Foundations: In newer homes, concrete slash foundations are poured directly into the ground, providing no basement or crawl space. While generally sturdy, these foundations are prone to greater shifting due to the natural settling of the surrounding soil and hydrostatic pressure. 
4. Stone Foundations: Older homes may have stone or rubble foundations, which add historic charm but can deteriorate without proper maintenance. If properly graded and maintained, these foundations can last long and may still hold up today. 

Each foundation type has unique vulnerabilities. Recognizing yours can help you determine the appropriate preventive measures and solutions for potential issues.

What Causes Foundation Issues?

Foundation problems don’t occur overnight. They often result from environmental, structural, and homeowner neglect. 

Foundation issues can take many forms, from deteriorated basement walls that allow water to seep through to shifting soil that causes uneven floors. 

Generally, some factors in Northeast Pennsylvania that contribute to foundation damage include:

• Soil Movement: The region’s expansive clay soils absorb water and expand, pushing against the foundation. Conversely, dry periods cause the soil to shrink, creating voids.
• Water Damage: Improper drainage, clogged gutters, and leaking pipes can saturate the soil, leading to erosion or hydrostatic pressure against the foundation walls.
• Freeze-Thaw Cycles: During cold winters, water in the soil freezes and expands, exerting upward pressure on the foundation. When it thaws, the soil settles unevenly.
• Tree Roots: Trees planted too close to a home can cause damage. As roots grow, they can shift soil or directly impact foundation walls.
• Construction Errors: Poor design, inadequate materials, or rushed construction can result in a weak foundation from the start. We’ll often find that many older homes lack the proper foundation support needed to support their home. 

9 Signs You May Have Foundation Damage

Unfortunately, many homeowners are not trained to spot foundation problems until they start to impact daily life and result in noticeable cracks and shifts in the home’s interior. Some signs that homeowners should be aware of over time include:

1. Cracks in Walls or Floors

As your home settles, it’s natural to spot cracks on your walls, ceiling, and floors. However, not all cracks are created equal.

For example, vertical cracks are considered innocuous and a natural part of foundation settling. However, vertical cracks that extend from the wall to the ceiling or floor could be worrisome and indicate issues with the foundation. 

Horizontal cracks are equally concerning as they could indicate rapid shifting in one area of the foundation compared to another.

Finally, stairstep cracks, especially along masonry objects, will indicate uneven settling and a more extensive problem that warrants investigation. 

2. Uneven or Sloping Floors

Uneven settling in different areas of the home will cause the house to shift on different axis points, causing floors to slope. It’s essential to look for other signs of foundation damage, as sloping or buckling floors could also be a problem with the floor joist or subfloor underneath. 

3. Sticking Doors and Windows

One of the most common signs of foundation damage that homeowners tend to ignore is sticking windows and doors. 

Doors and windows that no longer fit their frames or are difficult to open and close may signal a structural shift. If you notice doors that don’t open properly or even have slightly shifted frames that don’t allow the striker to hit the latch plate, it could indicate the sinking or settling of the foundation.

Another sign to look for is foggy windows, which could result from a damaged seal due to the foundation settling. 

4. Bowed Walls

If you have a basement foundation, look at your walls to see if they are bowing, cracking, or bulging in different spots. This could indicate hydrostatic pressure from outside soil that has saturated, shifted, and expanded.

5. Gaps Around Doors or Window

Look for gaps between walls and door and window frames, which indicate uneven settling. This is common in older homes and easily visible during the day when light can pierce through these openings. 

6. Water Intrusion

While moisture in basements or crawl spaces is very common in areas prone to flooding by the river or even up on a hill, like Clarks Summit and Pittston, it could eventually eat away at your foundation. Look for signs of water damage, such as cracks in the wall, deterioration, or staining of the floors. 

7. Chimney Movement

A leaning or cracking chimney often indicates foundation instability. Chimneys are heavy and rely on a solid base. Have a chimney expert examine the top and interior of your chimney for signs of damage. 

8. Foundation Cracks

Visible cracks on the exterior foundation walls, particularly horizontal ones, clearly indicate trouble. These will be visible on the floor or walls of your foundation. 

9. Persistent Musty Odor

Finally, dampness from foundation leaks can lead to mold and mildew growth, creating an unpleasant smell in the home. Regularly check moisture in your basement or crawl space and look for water intrusion after rain or snow events.

The Importance of a Foundation Inspection

A home’s foundation provides support for the rest of the house. Unfortunately, once your foundation starts to experience problems, you will most likely notice problems in other areas of your home. 

For this reason, getting a foundation inspection at the first sign of a problem is important to identify the cause and fix any lingering issues. 

A professional foundation inspection is an investment in your home’s longevity and value. Whether you are buying or selling a home or are concerned about your existing foundation, a home foundation inspection is essential for your safety and peace of mind. A home inspection will check for foundation issues and any issues pertaining to the foundation, such as poor drainage or broken window seals. 

FAQs

Does homeowners’ insurance cover foundation repairs?

It depends on the cause. Insurance often covers sudden damage from earthquakes or floods but typically excludes gradual damage from soil movement or water intrusion. Review your policy for specifics.

What can I do to prevent foundation problems?

Ensure proper drainage around your home, maintain a consistent moisture level in the soil, and avoid planting trees too close to the foundation. Regularly clean gutters and downspouts to direct water away from your foundation.

How often should I inspect my foundation?

Visually inspect your foundation twice a year—once in the spring and once in the fall. Professional inspections should be scheduled every few years or whenever you notice potential warning signs.

Northeast Pennsylvania is known for having cold winters and fairly warm summers. While it doesn’t rain as much as, say, Portland, annual rain and snowfall totals are higher than national averages, producing a somewhat wet and humid climate throughout the year.

However, rain and excess heat are not the only causes of mold inside homes. Water damage from leaky or busted pipes can often cause massive damage hidden beneath your walls, one of which is mold. 

Unfortunately, mold mostly lies beneath the surfaces of homes and can be easily missed during a home inspection. Among all of the additional closing costs you need to negotiate during a home transaction, a mold inspection may be one you’re liable to overlook.

Even if you own a home and have discovered signs of a water leak or poor ventilation, a mold inspection can be very valuable to your health. 

What Are the Health Effects of Mold Exposure?

Mold is a fungus that can enter our lungs when we breathe in or irritate our skin when we come in contact with it. While some strains of mold are more dangerous than others, the CDC lists the general symptoms of mold exposure as:

• A stuffy or runny nose
• Soar throat
• Wheezing or coughing
• Asthma-like symptoms 

The effects are worse for people who are immunocompromised. 

While it is possible to live among mold, it can greatly affect your quality of life and point to deeper issues in your home.

Why Mold Points to Deeper Issues in Your Home

Mold requires moisture in order to reproduce, which is why mold is found on wet surfaces of your home. While mold in and of itself is certainly hazardous, it can point to one of two issues in your home:

• Previous or existing water damage
• Poor ventilation

The former could mean deeper structural issues if the water damage was not properly repaired before putting the home on the market. Water-damaged homes value significantly less and can have other outstanding issues, such as pests or a musty odor that lingers. 

Poor ventilation will also need to be fixed and will certainly be marked in a home inspection report. 

Where Does Mold Typically Grow in a Home?

What makes mold so difficult to detect with a visual inspection is that mold typically grows on the inside of your home, behind your walls and floorboards. 

While some areas, such as bathrooms, basements, and kitchens, may be more prone to mold, mold can grow just about anywhere there is exposure to moisture. 

The most common areas in a home where mold is found include:

• Behind walls that have had water damage
• In damp basements with poor ventilation (typically on ceilings and walls)
• Underneath sinks with water leaks
• Underneath floor boards where water has seeped through 
• In HVAC systems that have not been properly cleaned
• Inside chimneys 
• Between windowsills and screens
• Behind outdoor shutters exposed to the elements
• Around siding and decks that have not been properly sealed or stained

How Does a Mold Inspection Differ from a Regular Inspection?

Mold inspections differ from regular inspections, which investigate the areas above where mold is most commonly found. A mold inspector is specially trained and licensed by a credentialed agency to know where to look for mold and what signs to look for.

These signs often include:

• Previous water damage in the home.
• Areas with poor ventilation, such as bathrooms.
• Homes without proper waterproofing, such as sump pumps.

Your mold inspector will also send off any mold samples they find for testing to determine the species, hazard level, and best course of action.

When Is a Mold Inspection Recommended?

While we recommend conducting a mold inspection anytime before purchasing a home, there are several situations where it may be more recommended than others:

• You are buying or selling a home.
• The home lies in a flood zone.
• The home is older and has poor ventilation.
• The home shows previous signs of water damage.
• The home is well taken care of and has other issues. 

How Much Does a Mold Inspection Cost?

Many people may be interested in a mold inspection but put off by the cost. According to Angi’s List, the national average for mold inspection costs ranges between $302 to $1,046. However, prices in Northeast Pennsylvania tend to fall on the lower end of the range and you can shop around among several inspectors for a more competitive quote. 

In our opinion, the cost of a mold inspection is well worth it compared with the cost of mold remediation and the ability to potentially bundle these costs into closing or have the seller cover them.

Is a Mold Inspection Worth It?

It can be easy to forgo a mold inspection, but there are many personal and financial benefits that the added peace of mind of having a mold-free home can afford. 

• Identify Hidden Issues: Mold often grows in concealed areas like behind walls, under flooring, or in HVAC systems, which aren’t typically assessed during standard home inspections. Detecting these hidden problems early can save you from future surprises.
• Protect Your Health: Mold exposure poses risks to your health, especially if you or your family members have allergies, asthma, or other respiratory issues. A mold inspection ensures a safer environment in your new home.
• Prevent Costly Repairs: Mold remediation and repairing underlying issues like leaks can be expensive. Identifying problems during the inspection phase allows for price negotiations or requiring the seller to make repairs.
• Assess Moisture Problems: Mold is a symptom of moisture issues such as leaks, poor drainage, or inadequate ventilation. Understanding the source of moisture can help prevent long-term damage and recurring mold growth.
• Ensure a Safe Investment: A mold inspection provides peace of mind, ensuring that your financial investment is sound and you won’t face unexpected remediation costs post-purchase.

When it comes down to brass tax, ordering a mold inspection is a matter or risk vs peace of mind. While some people may be put off by the cost of a mold inspection, it is also significantly less than the cost of remediation and can be covered by the seller in some cases. Overall, we like to say that you can’t put a price on peace of mind or your health.

FAQs

Do I need a mold inspection if the house looks clean?
Yes, mold can grow in hidden areas like behind walls, under carpets, or inside HVAC systems, even in clean-looking homes.

Are mold inspections included in regular home inspections?
No, mold inspections are typically separate and require a specialist to conduct air and surface testing.

What happens if mold is found during the inspection?

You can negotiate with the seller to address the issue, reduce the purchase price, or decide not to proceed with the purchase. Read more on what to do if you find mold in your home. 

We’ve conducted thousands of home inspections in and around the Scranton/Wilkes-Barre area and have seen everything from do-it-yourself wiring to slanted foundations you couldn’t walk on straight.

In today’s hot real estate market, it’s common for homebuyers to forgo a home inspection to make their offer more competitive. However, this strategy could put your safety and your money at risk.

We understand the financial risks of buying a home, which is why our home inspection reports are designed to be as thorough and professional as possible. 

Through our years of experience in the field and some additional research, we’ve uncovered the most common home inspection problems for homes in the Northeast PA region and much of the nation. Let’s dive in!

11 Of the Most Common Home Inspection Issues

Unfortunately, the most common home inspection problems we find with many homes in the area tend to be the most expensive repairs. 

It often makes sense as many homeowners don’t have the available capital to make these repairs and thus dump their home on the market, hoping it will sell in spite of these flaws or that they will be missed.

Understanding and identifying these common home inspection red flags will help you avoid costly repairs and give you greater peace of mind. 

1. Roof Issues

According to a survey by the Inspection Support Network (ISN), roof issues were the most common issue cited on 19.7% of all inspection reports. 

Regardless of the type of home you have, most people in the northeast tend to have asphalt shingle roofs, which last between 15-30 years on average.

However, excessive rainfall, poor drainage, low-lying tree branches, squirrels, and extreme weather can cause immediate damage or diminish the longevity of your shingles very quickly. Some of the most common issues we tend to find with roofs include:

• Missing or damaged shingles
• Leaks and water damage
• Improper flashing installation
• Mold or algae growth

While repairing a roof may only cost a few hundred dollars. Replacements can total tens of thousands of dollars, depending on the size and contractor. 

Mountain to Valley Home Inspectors uses a drone to assist with roof inspections that provide high-level details about the condition of your roof for the most accurate analysis possible. 

2. Outdated Electrical Wiring and Panels

The second most common issue cited in the ISN report that many people may overlook is outdated electrical wiring. If you’ve ever looked into a perfectly preserved Victorian, Tudor, or Colonial home in the area, you’ve probably run into nob-and-tube wiring that doesn’t pass code. 

However, aluminum wiring–commonly found in homes built between 1965 through 1973–is also another red flag that tends to deteriorate faster than copper and is a fire hazard.

Likewise, poor electrical wiring on your circuit panels that causes breakers to trip is another common issue we frequently run into that can be hazardous and inconvenient.  

3. Foundation Cracks and Damage

Homeowners often ignore foundation and structural issues due to their costly repairs, but they can cause a whole host of problems, from inviting moisture to damaging walls and ceilings.

Some signs of structural issues commonly found on home inspection reports in the area include:

• Cracks in walls or foundations
• Uneven floors
• Water intrusion in basements
• Rotting or damaged support beams

Don’t think that foundation issues are strictly limited to older homes. Often, newer homes built in the last 10-15 years suffer from structural issues due to poor soil compaction that doesn’t allow the foundation to settle properly. 

4. Water Damage 

Water damage can vary based on the build and location of the home, but damage from flooding can be very apparent for many homes that line the Susquehanna River. Additionally, leaky pipes that homeowners may not be aware of can also cause substantial damage. 

Unfortunately, water damage can be difficult to clean up as it can seep into walls, damage electrical wiring, cause mold, and rot out wooden beams, which may go unnoticed in a standard home inspection report. Therefore, any sign of water damage, such as stained walls, must be investigated further.

5. Plumbing

Nearly every home will experience some minor plumbing issues over its lifetime, and many of these can be fairly minor. Nevertheless, addressing any leaks or backflows before they lead to water damage or flooding is still important. 

We also tend to note any Polybutylene Plastic supply lines that are more susceptible to leaks. 

6. Poor Drainage

Your gutters may be something you ignore every year, but they play an essential role in protecting your foundation. Any drainage issues from downspouts, including clogged or damaged gutters, will be flagged on a home inspection report. While repairs are fairly inexpensive, they should be addressed immediately to protect your foundation. 

7. Sticking Windows and Doors

You might not believe it, but the third most common issue cited in the ISN report was sticking or outdated windows. We frequently encounter this issue with older homes in the area that have windows or doors that stick or won’t open. This can cause ventilation issues, which can lead to excess humidity or carbon monoxide. 

Windows and doors are also common points where air leakages have occurred, especially if either has separated from the frame of your house. 

8. Cracked Floor Joists

Cracked or rotting floor joists are just as common and dangerous as foundation issues. Measuring your floors to see if they are balanced is a good idea for homes with a basement or a second story. It’s actually very common for newer homes with lesser quality wood or recently remodeled homes to have joist issues, which can threaten the structural integrity of the home. 

9. Trees Close to the House

Trees with low-lying branches are a very common red flag we see on houses all across the area. Known for our dense forested mountains, many homes tend to have a cluster of trees in their front or backyard that can put their roof at risk. 

10. HVAC Issues

During inspections, we will also flag any HVAC issues, which typically arise from:

• Poor maintenance
• Clogged filters
• Duct leaks
• Outdated or inefficient systems

Not only will the efficiency of these systems decline, but replacement may also be necessary, which could cost thousands of dollars. 

11. Deck and Patio Issues

Finally, we tend to encounter a lot of shoddy workmanship when it comes to both professional and DIY decks and patios. 

From poor staining to uneven ground and even wooden planks that have rotted, we recommend that sellers fix these problems before proceeding with a sale, as they can be extremely hazardous.

Additional Red Flags Not Covered in Home Inspection Reports

While home inspection reports are thorough and cover most areas of your home, there may be some additional areas that you may want to hire for a separate inspection.

• Mold: It’s very easy to miss mold during a home inspection, as mold tends to proliferate in dark and wet places, such as behind your walls, a drop ceiling, or your HVAC system. We recommend all first-time homebuyers conduct a separate mold inspection, especially if you’re purchasing an older home. 

• Septic/Sewage System: Most homeowners are unaware that they are responsible for many of the pipes connected to their house from their sewage system. While it’s not entirely necessary to inspect these pipes, we do recommend getting an inspection done on your septic system if you don’t have public sewage. Since septic systems require more maintenance, they tend to run into more problems. 

• Waterproofing: If you live in a flood zone or on a hill, it’s a good idea to determine if your basement is properly waterproofed. This will help prevent water damage from heavy rainfall or snow. 

• Water Quality: If you purchase a home with well water, it’s a good idea to get a water sample test to determine if it is safe for consumption.
• Radon: Radon is a silent and harmful gas that tends to emit in higher concentrations from old mine shafts. Get a radon test done to see if there are any steps that need to be taken to remove or protect your home from radon.

By understanding these common home inspection issues, you can determine what the right course is, as many of these are bound to come up on any home inspection report. 

FAQs

What should I do if a home inspection report reveals significant issues?

If major problems are identified, consult a contractor or specialist for repair estimates. Buyers can negotiate with sellers for repairs or price adjustments to avoid being on the hook.

Are home inspections mandatory?

While not legally required, most lenders insist on inspections to ensure the property’s condition and underwrite any loan.

Can I waive a home inspection to gain a competitive edge in the market?

Waiving an inspection is risky, as it leaves you unaware of potentially costly repairs.
