Radon Testing in Gilmore City

Radon Testing in Gilmore City, Pocahontas County, by Closer Look Inspectors. Gilmore City is Iowa's self-styled Limestone Capital, a quarry town split down its main street by the Pocahontas-Humboldt county line.

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.

Local housing

Homes in Gilmore City.

Gilmore City housing runs to early-1900s homes from the quarry-town years and postwar houses on the outer blocks, across both sides of Gilmore Street, where the Pocahontas-Humboldt county line runs down the middle, on Des Moines Lobe till over shallow limestone, on the northeastern rim of the buried Manson crater — and that mix shapes what a radon testing here needs to find.

Local conditions in Gilmore City

Gilmore City 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. Gilmore City sits in Pocahontas 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 Gilmore City-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.
Does the limestone under Gilmore City affect a home inspection?
It shapes the foundation read. Bedrock sits close enough to the surface here to support two quarries, so we pay attention to how each house's footings, basement walls and drainage handle that ground, and to any signs of movement. The older quarry-era stock gets services dated precisely and a sewer scope on the original streets. A 48-hour radon test is recommended — both counties are Radon Zone 1.
