Why Do Easton Homes Have Elevated Radon?
Geology: Pennsylvania's long heating season drives the stack effect — warm indoor air rising creates negative pressure that pulls radon-laden soil gas through foundation cracks and sumps. Winter readings commonly run well above summer levels, so a winter short-term or a long-term test best reflects true exposure.
Permits: Pennsylvania requires radon mitigation work to be performed by a DEP-certified contractor (Radon Certification Act, 63 P.S. § 2001 et seq.). Northampton County homeowners should confirm a contractor's PA certification ID and obtain post-mitigation testing to verify levels below 4 pCi/L.

How the calculator maps test results to EPA guidance

|---|---|---|
| 0.0 – 1.9 | Below average — low | No action needed. Re-test every 2 years or after major renovation. |

Pennsylvania Real Estate Seller Disclosure Law (68 Pa. C.S. § 7301-7315) requires sellers to disclose any known radon test results to buyers. In practice, most Easton real estate transactions now include a radon contingency in the purchase agreement — and given that 51% of Easton homes test elevated, buyers are increasingly insisting on pre-closing mitigation when results exceed 4 pCi/L.
Our partner contractor network handles closing-timeline mitigations within typical 7–14 day windows, including post-mitigation verification testing to satisfy lender and inspector requirements.
Are Winter Radon Levels Higher in Easton?
Yes. Easton's cold winters intensify radon entry through the stack effect — heated indoor air rising creates negative pressure in basements that pulls soil gas into the home at higher rates than warmer climates. Easton winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with Easton winters. If your Easton home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
