Radon Testing in Lehigh

Radon Testing in Lehigh, Webster County, by Closer Look Inspectors — a 145-minute drive away. Lehigh is a former coal-and-clay town down in the Des Moines River valley, 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 Lehigh.

Lehigh housing runs to former coal-and-clay-town homes down in the valley, across the core in the Des Moines River valley, on Des Moines River valley walls with a coal and clay-products legacy — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Lehigh

Lehigh 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. Lehigh sits in Webster 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 42 inches in northern Iowa, and that annual freeze-thaw cycle drives the settlement cracks and ice-dam wear we calibrate every Lehigh 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.
What is specific to Lehigh?
The valley. Lehigh sits down in the Des Moines River gorge where coal and clay were once dug, so hillside lots concentrate runoff against foundations, retaining structures carry real load, and river-adjacent ground gets its flood history established. The older stock adds the full systems-by-age read.
