Radon Testing in Farnhamville

Radon Testing in Farnhamville, Calhoun County, by Closer Look Inspectors. Farnhamville is an 1881 railroad town on Iowa 175 straddling the Calhoun-Webster 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 Farnhamville.

Farnhamville housing runs to early-1900s homes from the 1881 plat and postwar houses on the outer blocks, across the grid along Iowa 175 on both sides of the Calhoun-Webster county line, on flat Des Moines Lobe till — and that mix shapes what a radon testing here needs to find.

Local conditions in Farnhamville

Farnhamville 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. Farnhamville sits in Calhoun 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 Farnhamville-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 county line matter for a Farnhamville home?
Only for paperwork — the ground and the houses are the same on both sides. Both Calhoun and Webster counties are Radon Zone 1, so a 48-hour test is standard. The inspection dates the early-1900s stock's services precisely, recommends a sewer scope on the older streets, and reads grading and basement moisture closely on slow-draining till.
