Radon Testing in Oak Park Heights

Radon Testing in Oak Park Heights, Washington County, by Closer Look Inspectors. Oak Park Heights is a St. Croix bluff-top city of old Oak Park lots, retail corridor and newer subdivisions, 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.

Oak Park Heights

Calibrated

Tuned to Oak Park Heights.

Oak Park Heights housing runs to older houses in the original Oak Park plat and on the bluffs, mid-century homes near the commercial corridor, and newer townhome and single-family subdivisions, across the bluff-top streets above the St. Croix River, the Highway 36 and Highway 95 corridors, and the newer subdivisions, on St. Croix River valley bluffs and terraces in eastern Washington County — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Oak Park Heights

Oak Park Heights does not run a point-of-sale housing ordinance, which makes an independent inspection the only thorough, buyer-side read on the home. Oak Park Heights 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 we calibrate every Oak Park Heights 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.

What should I check in an older home in the original Oak Park plat?

Start below the house: foundation cracks, past moisture, and the condition of the sewer line. Then the systems: older wiring and panels, plumbing, windows, chimney and roofing. Houses of this age often have been repaired over decades by different hands, so we look for patchwork and unpermitted work. We record what we see so you can plan repairs.

Oak Park Heights sits on St. Croix bluffs — what does that mean for inspecting?

Slopes matter. The city was platted as Oak Park in 1857 and re-platted as Oak Park Heights in 1938, with the 1932 Log Cabin and the Stillwater Overlook (1939) listed on the National Register. Homes on bluff edges and hillsides need checks for retaining walls, foundation movement, drainage and erosion. Older houses get a close look at basements, wiring and roofs. Newer subdivisions get grading, deck ledger and flashing checks.
