Radon Testing in Lewiston

Radon Testing in Lewiston, Winona County, by Closer Look Inspectors. Lewiston is a farm town on the upland plateau above the bluff valleys.

Radon testing places an EPA-protocol continuous monitor on a home's lowest livable level to measure radon gas — and it matters across Minnesota, where more than two in five homes test above the action level.

Local housing

Homes in Lewiston.

Lewiston housing runs to upland farm-town homes, across the town core on the plateau, on upland plateau above the bluff valleys — and that mix shapes what a radon testing here needs to find.

Local conditions in Lewiston

Out in Lewiston, many properties sit beyond city sewer and water on private septic systems and wells, so we flag those for the specialized testing they deserve. Lewiston sits in Winona County, in EPA Radon Zone 1, and MDH reports more than two in five Minnesota homes have radon levels that pose a significant health risk. Finished basements concentrate radon, and only a 48-hour test tells you the number. Footings here must reach the 3-1/2-foot depth Minnesota Rules 1303.1600 set for the southern frost zone, and that annual freeze-thaw cycle is what drives the settlement cracks, frost heave and ice-dam wear that Lewiston-area homes face.
