|---|---|---|
| 0.0 – 1.9 | Below average — low | No action needed. Re-test every 2 years or after major renovation. |
| 2.0 – 3.9 | Elevated — EPA "consider mitigating" | Consider mitigation, especially with smokers, children, or lower-level bedrooms. Run a long-term (90+ day) test for confirmation. |

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 State College real estate transactions now include a radon contingency in the purchase agreement — and given that 48% of State College 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 State College?
Yes. State College'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. State College winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with State College winters. If your State College home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
