Why Do Kettering Homes Have Elevated Radon?
Geology: Ohio's cold winters intensify the stack effect, drawing radon-laden soil gas up through foundation cracks, sumps, and slab penetrations. Indoor radon commonly tests higher in winter, so a cold-season short-term test or a long-term test gives the most reliable reading.
Permits: Ohio requires radon mitigation contractors to hold an Ohio Department of Health (ODH) radon license. Montgomery County homeowners should verify the contractor's ODH license number and obtain post-mitigation testing to confirm levels fall below the 4 pCi/L action level.

Ohio Residential Property Disclosure Act (Ohio Rev. Code § 5302.30) requires sellers to disclose any known radon test results to buyers. In practice, most Kettering real estate transactions now include a radon contingency in the purchase agreement — and given that 34% of Kettering 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 Kettering?
Yes. Kettering'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. Kettering winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with Kettering winters. If your Kettering home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
