Radon Testing in Henriette

Radon Testing in Henriette, Pine County, by Closer Look Inspectors. Henriette is a Pine County village on Highway 107 that began life as Cornell, 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 Minnesota, where more than two in five homes test above the action level.

Calibrated

Tuned to Henriette.

Henriette housing runs to a small mix of early-1900s village houses and mid-century homes, with a few newer builds, across the few blocks of the village along Highway 107 and Pine County Road 11, and the farms and acreages around them, on sandy glacial outwash and drift plain of southwestern Pine County — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Henriette

Henriette does not run a point-of-sale housing ordinance, which makes an independent inspection the only thorough, buyer-side read on the home. Henriette sits in Pine County, in EPA Radon Zone 2 — a moderate county rating, but MDH reports more than two in five Minnesota homes have radon levels that pose a significant health risk, and a county zone never predicts one house. Finished basements concentrate radon, and only a 48-hour test tells you the number. Footings here must reach the five-foot depth Minnesota Rules 1303.1600 require in the state's northern frost zone, and that annual freeze-thaw cycle is what drives the settlement cracks, frost heave and ice-dam wear we calibrate every Henriette visit to find.

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.
Henriette started as Cornell — how old is the housing?
Most of it is old. The village was founded as Cornell, became Henriette in 1913, was incorporated in 1920, peaked at 148 residents in 1940, and had fallen to 57 by 1950 and again by 2020. Houses here run to the early and mid-1900s with newer replacements mixed in. We check foundations and sill plates, roof and chimney condition, outdated wiring and plumbing, and private wells and septic. Pine County is Minnesota Frost Zone I, so footing depth on additions is worth a look.
