Washburn sits on the Missouri River about thirty-five minutes north of Bismarck — the McLean County seat, and the town where the Lewis & Clark story pauses for winter: the expedition built Fort Mandan just upriver and waited out 1804–05 there, and the Lewis & Clark Interpretive Center anchors the town today. The river location that made Washburn worth settling is also its radon story: the Missouri here cuts through the same uranium-bearing Pierre Shale the USGS flagged decades ago, with beds in this valley carrying measurable uranium — the bedrock source under McLean County's Zone 1 designation.
Washburn housing runs the full range — original townsite homes with decades-old basements, river-view properties on the bluffs, and workforce housing from the coal-and-power era at the county's industrial edge. All of it shares the statewide two-in-three odds, and none of it should guess. A winter test under closed-house conditions — which in Washburn is just called winter — gives the honest number.
Washburn is a straight run up Highway 83 from our Bismarck base — scheduled service, not a special trip.
Washburn wears two hats — river town and county seat — and the second one comes with buildings: the courthouse, the school, county offices, and the civic spaces where McLean County residents spend regular hours. Ground-contact public buildings sit on the same Zone 1 till the houses do, and commercial radon testing is the cheap, zone-mapped way for a board or district to answer the question before it's asked. For homeowners, the same logic scales down: one test, one number, and — if it's high — one afternoon of verified work.
Two-thirds of North Dakota homes test high. One call gets you the number — and the fix if you need it.
(701) 401-5204Assume yes until tested: McLean County is EPA Zone 1 like every North Dakota county, and the state DEQ reports 63 percent of homes statewide above the 4.0 pCi/L action level. The only way to know a specific Washburn house is to test it.
No trip-charge games. Washburn is inside the normal working range from our Bismarck–Mandan base, and jobs there schedule the same week like everything else.
The same honest range as the rest of the metro: standard sub-slab systems typically about $1,000 to $2,500 installed, with foundation type the biggest variable. See the full cost breakdown.
