Kentucky Revised Statute § 324.360 requires sellers to disclose any known radon test results to buyers. In practice, most Nicholasville real estate transactions now include a radon contingency in the purchase agreement — and given that 55% of Nicholasville 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 Nicholasville?
Yes. Nicholasville'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. Nicholasville winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with Nicholasville winters. If your Nicholasville home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
