Radon Testing in Adel

Radon Testing in Adel, Dallas County, by Closer Look Inspectors — a 218-minute drive away. Adel is a brick-paved county seat on the Raccoon River, its historic square ringed by new growth, 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 Adel.

Adel housing runs to Victorian and early-1900s homes around the brick-paved square, with new growth, across the historic square district and the newer subdivisions, on Raccoon River valley edge at the lobe's western margin — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Adel

Adel 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. Adel sits in Dallas 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 Adel 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 Adel homes?
The historic core around the brick streets is genuinely old — stone foundations, original services and masonry that has moved — while the new edges are boomburb stock. River-adjacent lots add the Raccoon valley questions: flood history, grading and basement moisture, which we establish rather than assume.
