Why Do Eagan Homes Have Elevated Radon?
Eagan sits in Dakota County in Minnesota's glacial-till lowlands. Minnesota's statewide indoor radon average is 4.4 pCi/L — well above the EPA action level of 4.0 pCi/L and the U.S. average of 1.3 pCi/L. With glacial-till lowlands geology and full-basement housing common in Eagan, EPA and Minnesota health officials recommend every home be tested.

Geology: Cold Minnesota winters intensify the stack effect — heated indoor air rising creates negative pressure that pulls radon-laden soil gas into basements. Winter radon readings commonly run 30–50% higher than summer.
Permits: Minnesota does not require a permit for residential radon mitigation, but Minnesota's Radon Awareness Act (Minn. Stat. §144.496) mandates disclosure at sale; MDH licenses radon professionals. Post-mitigation verification testing is recommended within 30 days of activation.

Minnesota law requires sellers to disclose any known radon test results to buyers. In practice, most Eagan real estate transactions now include a radon contingency in the purchase agreement — and given that 40% of Eagan 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 Eagan?
Yes. Eagan'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. Eagan winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with Eagan winters. If your Eagan home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
