Radon Testing in Willernie

Radon Testing in Willernie, Washington County, by Closer Look Inspectors. Willernie is a Washington County city of about 0.13 square miles ringed entirely by Mahtomedi.

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 Willernie.

Willernie housing runs to small older houses and cottages on narrow lots, with a few newer rebuilds among them, across the compact city along County Road 12, with every side bordering Mahtomedi, on glacial drift uplands in the lake-dotted country of western Washington County — and that mix shapes what a radon testing here needs to find.

Local conditions in Willernie

Willernie does not run a point-of-sale housing ordinance, which makes an independent inspection the only thorough, buyer-side read on the home. Willernie sits in Washington 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 Willernie-area homes face.

Questions

Common questions.

Is radon really a concern in Minnesota?
Yes. The Minnesota Department of Health reports that more than two in five Minnesota 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.
Does it matter that Willernie is surrounded by Mahtomedi when I buy a house?
Not for the approach, which is the same on every property. It can matter for the paperwork and services around the sale, such as who to call for permits and utilities, so confirm those with your agent and the city. What we do is inspect the house itself: structure, roof, electrical, plumbing, heating and cooling, and grading. Then we give you a report you can use to negotiate.
What is different about buying in Willernie, a city surrounded by Mahtomedi?
Willernie covers about 0.13 square miles, so houses sit close together on small lots with little room for drainage to go anywhere. It peaked at 697 residents in 1970 and has been near 500 since 2000. Lot grading and roof runoff that can end up on the neighbor, property lines and fences, and additions and detached garages tacked onto older cottages are the things to watch. Panels and wiring in the older cottage-era houses are worth a look, as are the chimney and roof flashing, which take the most wear on small homes.
