Radon Testing in Big Lake

Radon Testing in Big Lake, Sherburne County, by Closer Look Inspectors. Big Lake is a Northstar-corridor lake town of 1990s-2000s subdivisions on sandy outwash.

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 Big Lake.

Big Lake housing runs to 1990s-2000s subdivisions around the lakes, across the Big Lake and Mitchell Lake neighborhoods and the newer subdivisions near the Northstar station, on flat sandy outwash of the Anoka Sand Plain — and that mix shapes what a radon testing here needs to find.

Local conditions in Big Lake

Out in Big Lake, many properties sit beyond city sewer and water on private septic systems and wells, so we flag those for the specialized testing they deserve. Big Lake sits in Sherburne 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 Big Lake-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.
Are the old cabins near Big Lake and Mitchell Lake safe to live in year-round?
Many were built for summer use, so whether they can handle winter matters: insulation, heating, plumbing freeze protection, foundations and crawlspaces. Additions may have been built without much planning, so how they connect to the original structure is worth watching. A cabin can work well as a home, but the conversion should be done properly, and we list any gaps we see.
Is radon a concern in Big Lake?
Yes — sandy, highly permeable outwash soils move soil gas readily, and Sherburne County sits in EPA Zone 1. We recommend testing every home here, new construction included.
