Radon Testing in Liscomb

Radon Testing in Liscomb, Marshall County, by Closer Look Inspectors. Liscomb is a small Marshall County rail town of older homes platted in 1869.

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 Liscomb.

Liscomb housing runs to late-1800s and early-1900s frame homes from the town's 1869 platting, with a thin postwar layer, across the compact grid along the old Iowa Central alignment and the surrounding Marshall County farm ground, on Iowan Surface ground with long low slopes, and the scattered poorly drained pockets that region is known for — and that mix shapes what a radon testing here needs to find.

Local conditions in Liscomb

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 Liscomb home. Liscomb sits in Marshall 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 Liscomb-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.
Why do flat lots in Liscomb still get wet basements?
Because flat is not the same as well drained. Liscomb sits on the Iowan Surface, which the Iowa Geological Survey describes as gently inclined with long slopes and open horizons, and as carrying scattered areas of poor drainage and original wetlands. On ground like that water does not run off a lot, it sits on it, then works down against the foundation wall. So we still read grading within the first several feet of the house, downspout discharge distance, window-well drainage and sump performance, and look inside for the staining and efflorescence that says water has been there before.
