Radon Testing in St. Olaf

Radon Testing in St. Olaf, Clayton County, by Closer Look Inspectors. St. Olaf is a small Clayton County village of older homes in karst country.

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 St. Olaf.

St. Olaf housing runs to historic limestone and early-1900s frame homes, across the village core, on Driftless limestone bluffs and karst, with fractured rock close to the surface — and that mix shapes what a radon testing here needs to find.

Local conditions in St. Olaf

Around St. Olaf 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. St. Olaf sits in Clayton 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 St. Olaf-area homes face.

A 48-hour minimum under closed-house conditions; the result is delivered with your inspection report.
Do you cover St. Olaf?
St. Olaf sits in Clayton County karst, where limestone lies close to the surface and groundwater moves fast through fractured rock — so foundation drainage and private-well quality lead the read, and our Edgewood team covers it.
