Radon Testing in South Amana

Radon Testing in South Amana, Iowa County, by Closer Look Inspectors. South Amana is an Amana Colony village of communal-era brick and frame houses.

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 South Amana.

South Amana housing runs to pre-1932 communal-era Amana Colony buildings — brick-heavy here — alongside a small number of later houses, across the village street and its communal-era buildings, the old agricultural structures at the edges, and the farm ground of the Amana Society tract around it, on Iowa County ground on the Iowa River drainage, on the transition between the drift plain and the Iowan Surface — and that mix shapes what a radon testing here needs to find.

Local conditions in South Amana

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 South Amana home. South Amana sits in Iowa 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 South Amana-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.
What makes a South Amana house different to inspect?
Its walls. The Amana Colonies were designated a National Historic Landmark in 1965 and the pre-1932 communal-era buildings are contributing structures, and South Amana in particular emphasized brick — even its granary and chicken house were built of it. Colony construction also used nogging, unfired brick stacked dry between the wall studs, plus straw between floors. That behaves nothing like platform framing: different thermal performance, different moisture movement in the cavity, and real constraints on where you can cut, fasten or add insulation. It deserves to be judged on its own terms.
