Iowa Code requires sellers to disclose any known radon test results to buyers.

Are Winter Radon Levels Higher in West Des Moines?
Yes. West Des Moines'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. West Des Moines winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with West Des Moines winters. If your West Des Moines home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
