Radon Testing in Colo

Radon Testing in Colo, Story County, by Closer Look Inspectors — a 185-minute drive away. Colo is a Lincoln Highway crossroads town of older farm-town homes east of Nevada, 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.

Calibrated

Tuned to Colo.

Colo housing runs to older farm-town homes at the Lincoln Highway crossroads, across the town core, on flat Story County lobe till — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Colo

Colo sits on Des Moines Lobe till — heavy, poorly drained clay that holds water against foundations and moves with moisture, which is what drives basement seepage and foundation cracking across central Iowa. Colo sits in Story 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 Colo 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.
Do you cover Colo?
Yes — it sits just east of Nevada on our corridor. The Lincoln Highway-era stock is at or past the century mark, so original panels, layered plumbing and settled foundations lead the findings, with flat-till grading and Iowa's Zone 1 radon standing close behind.
