Radon Testing in Garwin

Radon Testing in Garwin, Tama County, by Closer Look Inspectors. Garwin is the first rail station west of Toledo, a small town of older homes.

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 Garwin.

Garwin housing runs to early-1900s rail-town frame homes with scattered postwar additions, across the compact town core along the old Toledo and Northwestern alignment, on Iowan Surface ground of long gentle slopes with pockets of original poor drainage — and that mix shapes what a radon testing here needs to find.

Local conditions in Garwin

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 Garwin home. Garwin sits in Tama 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 Garwin-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 is the most common wiring problem you write up in Garwin?
Additions to an old system rather than replacement of it. Garwin's stock dates to the era when this was the first station west of Toledo, so the typical house has had a modern panel installed while the branch circuits behind it stayed as they were. Grounding and bonding, double-taps, undersized conductors, reversed polarity and missing grounds at outlets are the electrical items to check, along with which parts of the system are new and which are not. Tama County is EPA Radon Zone 1 like all of Iowa.
