Radon Testing in Madrid

Radon Testing in Madrid, Boone County, by Closer Look Inspectors — a 195-minute drive away. Madrid is a former coal-camp town near the High Trestle Trail, with older stock and trail-era new builds, and we calibrate every visit to that.

Radon testing places an EPA-protocol continuous monitor on a home's lowest livable level to measure radon gas — and it matters across Iowa, which has the highest average indoor radon level of any state — roughly five in ten homes test above the action level.

Tuned to Madrid.

Madrid housing runs to former coal-camp housing and older town stock, plus trail-era new builds, across the town core and the newer edges near the High Trestle Trail, on lobe till above the Des Moines River valley — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Madrid

Madrid sits on Des Moines Lobe till — heavy, poorly drained clay that holds water against foundations and moves with moisture, which is what drives basement seepage and foundation cracking across central Iowa. Madrid sits in Boone County, and Iowa has the highest average indoor radon level of any state — the Iowa DNR puts roughly five in ten Iowa homes above the 4.0 pCi/L action level, and Iowa sellers must disclose known radon results on the property disclosure. Finished basements concentrate it, and only a 48-hour test gives you this home's number. Footings here are set below a frost line of roughly 36 to 42 inches, and that annual freeze-thaw cycle drives the settlement cracks and ice-dam wear we calibrate every Madrid visit to find.

Questions

Common questions.

Is radon really a concern in Iowa?
Yes. The Iowa Department of Natural Resources reports that roughly 50 percent of homes statewide measure above the EPA action level, and finished basements are where it concentrates.
How long does the test run?
A 48-hour minimum under closed-house conditions; the result is delivered with your inspection report.
Does Madrid's coal-camp past matter?
It shapes the stock — much of the older housing here began as modest miners' housing, since expanded and altered over a century, so we look hard at additions, foundations and the quality of layered work. Valley-rim lots add slope drainage, and the newer trail-era builds get a standard verification.
