Radon Testing in Ottumwa

Radon Testing in Ottumwa, Wapello County, by Closer Look Inspectors. Ottumwa is a Des Moines River industrial city of hillside Victorian and worker housing, and we calibrate every visit to that.

Radon testing places an EPA-protocol continuous monitor on a home's lowest livable level to measure radon gas — and it matters across Iowa, which has the highest average indoor radon level of any state — roughly five in ten homes test above the action level.

Tuned to Ottumwa.

Ottumwa housing runs to hillside Victorian and industrial worker housing above the Des Moines River, across the hillside neighborhoods and the river flats, on Des Moines River valley slopes and terraces — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Ottumwa

Iowa runs no municipal time-of-sale inspection ordinance, which makes an independent inspection the only thorough, buyer-side read on a Ottumwa home. Ottumwa sits in Wapello County, and Iowa has the highest average indoor radon level of any state — the Iowa DNR puts roughly five in ten Iowa homes above the 4.0 pCi/L action level, and Iowa sellers must disclose known radon results on the property disclosure. Finished basements concentrate it, and only a 48-hour test gives you this home's number. Footings here are set below a frost line of roughly 36 to 42 inches, and that annual freeze-thaw cycle drives the settlement cracks and ice-dam wear we calibrate every Ottumwa visit to find.

Questions

Common questions.

Is radon really a concern in Iowa?
Yes. The Iowa Department of Natural Resources reports that roughly 50 percent of homes statewide measure above the EPA action level, 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.
What is specific to Ottumwa homes?
Hillside and river-flat are two different inspections. The bluff-side Victorians carry stone foundations, retaining walls and slope drainage that concentrate runoff; the flats carry flood history and high-water-table basements where sump systems get verified rather than assumed. The industrial-era stock throughout gets its services and laterals dated.
