Radon Testing in Renwick

Radon Testing in Renwick, Humboldt County, by Closer Look Inspectors. Renwick is an 1882 railroad town in eastern Humboldt County near the Boone River.

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 Renwick.

Renwick housing runs to early-1900s homes from the town's 1882 plat and postwar houses from its 1970 peak, across the grid along Iowa 17 and the acreages toward the Boone River, on flat Des Moines Lobe till about a mile from the Boone River — and that mix shapes what a radon testing here needs to find.

Local conditions in Renwick

Renwick 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. Renwick sits in Humboldt 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 Renwick-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 inspect homes in Renwick?
Yes — Renwick is inside our Fort Dodge coverage, served from Buffalo Center. The stock splits between early-1900s houses that need the full systems-by-age read and postwar homes at second-replacement age for roofs and furnaces. Slow-draining till keeps grading and basement moisture on every report, and a 48-hour radon test is standard in Humboldt County.
