Radon Testing in Thornton

Radon Testing in Thornton, Cerro Gordo County, by Closer Look Inspectors. Thornton is a small farm town of older homes in southern Cerro Gordo County.

Radon testing places an EPA-protocol continuous monitor on a home's lowest livable level to measure radon gas — and it matters across Iowa, where Iowa HHS reports 71.6 percent of homes above the action level — the largest percentage of any state.

Split-level home with stone facing on a sloped lot — Radon Testing in Thornton, IAThornton
Local housing

Homes in Thornton.

Thornton housing runs to older farm-town homes with postwar additions, across the compact town core, on flat, heavy Des Moines Lobe till around Mason City — and that mix shapes what a radon testing here needs to find.

Local conditions in Thornton

Thornton 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. Thornton sits in Cerro Gordo County, and every Iowa county is EPA Radon Zone 1. Iowa HHS reports Iowa has the largest percentage of homes above the 4.0 pCi/L action level of any state — 71.6 percent in the Iowa Radon Survey — and the Iowa seller disclosure form asks for any known radon test results. Finished basements concentrate it, and only a 48-hour test gives you this home's number. Iowa leaves frost depth to the local building code rather than one statewide number, and the annual freeze-thaw cycle drives the settlement cracks and ice-dam wear that Thornton-area homes face.

Questions

Common questions.

Is radon really a concern in Iowa?
Yes. The Iowa Department of Natural Resources reports that more than two in five Iowa homes have radon levels that pose a significant health risk, 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.
Do you cover Thornton?
Yes. Around Thornton footings set below the locally required frost depth still see settlement cracks and ice-dam wear, and the flat till that was tiled farm ground drains slowly around town basements.
