Why Kennett Square Homeowners Need Radon Testing in Chester County
Radon is a colorless, odorless radioactive gas that seeps up from the soil and into homes through foundation cracks, basement floors, and gaps around pipes. You cannot see it, smell it, or taste it.
Yet it is deadly. The EPA estimates that radon is responsible for approximately 21,000 lung cancer deaths in the U.S. every year, making it the number one cause of lung cancer in non-smokers.
Kennett Square sits in a part of Chester County where the underlying geology creates above-average radon risk. Many of the borough’s charming older homes were built before radon was fully understood, with basements and crawl spaces that allow gas to accumulate over time.
If you have not had a radon inspection in Kennett Square, PA, in the past two years, your family may be breathing elevated levels of this dangerous gas right now without knowing it.

The Hidden Danger Beneath Kennett Square Homes
Kennett Square is beloved for its historic homes, garden character, and community charm. But many of the borough’s most attractive properties sit atop soil that naturally releases radon gas.
The granite-rich bedrock that runs through much of Chester County is a well-documented source of uranium decay, which produces radon. As the gas rises through the soil, it enters homes through the path of least resistance: basement floors, foundation walls, sump pump openings, and utility penetrations.
Once inside, radon accumulates. Without ventilation or mitigation, concentrations can reach dangerous levels in a matter of weeks. The EPA recommends taking action if radon levels reach 4 picocuries per liter (pCi/L) or higher, and many Chester County homes test well above that threshold.
Getting a certified radon inspection in Kennett Square, Chester County is the only reliable way to know your actual exposure level.
Why Gas Line Safety Is Part of Our Radon Testing in Kennett Square PA
Many homeowners are surprised to learn that our radon testing packages also include a natural gas safety inspection. The reason is simple, both hazards are invisible and found in Chester County homes every week.
Pennsylvania has a documented history of gas distribution incidents. Including a visible gas line safety check and valve testing in our entry-level package means you address two serious risks in a single visit, without paying for two separate inspections.
Our gas inspection covers all accessible, visible gas lines and includes safe operation testing of gas safety valves. If we spot anything concerning, we document it clearly so you can act quickly.

If elevated radon is found, you may be able to negotiate mitigation costs with the seller before closing, potentially saving thousands of dollars and protecting your family from long-term health risks.
How does radon get into a Kennett Square home?
Radon enters Kennett Square homes through foundation cracks, basement floor joints, sump pump pits, gaps around utility pipes, and hollow block walls. The granite-rich bedrock common in Chester County naturally releases radon as uranium in the soil decays, and the gas migrates upward through the soil into your home’s lowest levels.
What happens after a radon inspection finds high levels in my Chester County home?
If your radon inspection in Kennett Square, PA reveals levels at or above 4 pCi/L, the EPA recommends radon mitigation, typically a sub-slab depressurization system that vents radon gas safely out of your home. Mitigation is a well-established process and can reduce radon levels by up to 99% in most homes.
Does a radon test also check for mold in Kennett Square, PA?
Our Radon Inspection 3.0 ($597) and Radon Air and Health Safety Inspection ($997) packages both include mold-related testing. The $597 package includes a 10- to 15-page basement mold testing report, and the $997 package adds a visual HVAC mold inspection and full indoor air quality testing for hidden contaminants beyond mold.
How often should Kennett Square homeowners test for radon?
The EPA recommends radon testing every two years for homes that have not had mitigation installed, and after any major renovation that affects the foundation or lower levels of the home. If you have had a mitigation system installed, annual testing is recommended to confirm the system is still working effectively in your home in Kennett Square, PA.
