Radon Testing in Schleswig

Radon Testing in Schleswig, Crawford County, by Closer Look Inspectors. Schleswig is a German-settled Boyer Valley railroad town laid out in 1899 with buildings moved in from Hohenzollern, 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, where Iowa HHS reports 71.6 percent of homes above the action level — the largest percentage of any state.

Split-level home with stone facing on a sloped lot — Radon Testing in Schleswig, IASchleswig
Calibrated

Tuned to Schleswig.

Schleswig housing runs to houses from after the 1899 laying out of the town, with early-1900s frame homes, postwar ranches and newer construction, across the original 1899 plat and the streets and farm ground around it, on loess-capped ridges and hollows of the Southern Iowa Drift Plain in the Boyer Valley — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Schleswig

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 Schleswig home. Schleswig sits in Crawford 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 we calibrate every Schleswig visit to find.

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.
Low spots in Schleswig's original plat: do they still affect houses?
They can. When Schleswig was laid out in 1899, early sidewalks were built on beer barrels to raise them above low ground, which tells you the plat has real dips. Houses in those low spots and below neighboring lots collect surface water, and the town's roughly 830 residents live on ridges and hollows cut into loess and glacial till. We check lot grading, gutters and downspouts, foundation walls for stains and cracks, window wells, and the sump pump. Crawford County is EPA Radon Zone 1, so a 48-hour radon test is a sensible add-on.
