Iowa Code requires sellers to disclose any known radon test results to buyers. In practice, most Ankeny real estate transactions now include a radon contingency in the purchase agreement — and given that 73% of Ankeny 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 Ankeny?
Yes. Ankeny'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. Ankeny winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with Ankeny winters. If your Ankeny home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
