Radon Testing in Cresco

Radon Testing in Cresco, Howard County, by Closer Look Inspectors. Cresco is a small Driftless-edge county seat of early-1900s housing.

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 Cresco.

Cresco housing runs to early-1900s housing with postwar infill, across the town core, on Driftless-edge ground with limestone near surface — and that mix shapes what a radon testing here needs to find.

Local conditions in Cresco

Around Cresco the Driftless karst puts limestone close to the surface, so groundwater moves fast through fractured rock — which raises both foundation drainage questions and contamination risk on private wells. Cresco sits in Howard 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 Cresco-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 Cresco?
Yes. Howard County is well within range, and the Driftless-edge geology here makes drainage and foundation movement worth a careful read alongside the usual systems.
