Radon Testing in Guernsey

Radon Testing in Guernsey, Poweshiek County, by Closer Look Inspectors. Guernsey is a small village of older homes in eastern Poweshiek 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.

Local housing

Homes in Guernsey.

Guernsey housing runs to early-1900s farm-town homes with scattered postwar additions, across the village core, on rolling loess-mantled till of the Southern Iowa Drift Plain — and that mix shapes what a radon testing here needs to find.

Local conditions in Guernsey

No Iowa law requires a home inspection before a sale — the one mandatory time-of-transfer inspection covers private septic systems (Iowa Code 455B.172) — which makes an independent inspection the only thorough, buyer-side read on a Guernsey home. Guernsey sits in Poweshiek 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 Guernsey-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 Guernsey?
Guernsey is within our Montezuma team's range. Southern-Iowa drift-plain clay swells and shrinks with moisture, so foundation movement and grading lead most reports, and Iowa's Zone 1 radon standing makes a 48-hour test a smart add-on.
