Radon is an invisible, odorless radioactive gas that seeps into homes through foundation cracks, sump pumps, and basement floors. It’s the second leading cause of lung cancer in the United States, responsible for over 21,000 deaths annually, according to the EPA.
Homes in Northeast Pennsylvania sit on uranium-rich rocks along the Reading Prong, known to produce elevated radon levels that far exceed EPA-recommended levels. Without testing, you won’t know if dangerous concentrations are accumulating inside your home—often for years before symptoms appear.
Whether you’re buying, selling, or protecting your current home, certified radon testing gives you answers before exposure becomes a long-term health risk. Get lab-certified results in 72 hours or less so you can move on with real estate transactions quickly and comfortably.

Radon Exposure Goes Undetected Without Professional Testing
According to the PA Department of Environmental Protection, over 40% of homes in the commonwealth test higher than the EPA’s safe level of radon detection.
Northeast PA’s geology—particularly areas with shale, granite, and uranium deposits—creates ideal conditions for radon infiltration. Homes built on slabs, with basements, or near well water sources face even higher risks.
Because radon has no smell, taste, or visible warning signs, it accumulates silently in living spaces. Families often live with dangerous radon levels for years without knowing, increasing lung cancer risk with every breath.
The consequences of untested radon exposure include:
- Increased lung cancer risk, even in non-smokers
- Prolonged radiation exposure to children and pets
- Liability concerns for sellers who fail to disclose known radon issues
- Post-closing remediation costs ranging from $800 to $2,500+
- Delayed home sales during buyer negotiations
EPA guidelines recommend regular testing of every home, regardless of age or construction type. Radon levels can vary drastically between neighboring properties, making assumptions about safety unreliable.
Certified radon testing is the only way to confirm whether your home exceeds the EPA action level of 4.0 pCi/L and requires mitigation.
