About Bismarck Radon

Local, Blunt, and Verified by Test

Bismarck Radon exists to do one thing well: get the radon number in a Bismarck-area home measured honestly and, when it's high, get it fixed and proven fixed. One service, one metro. Radon mitigation in Bismarck and Mandan is not a side hustle bolted onto a general contracting business here — it's the whole page, every page.

The operating rules are simple, and they're on every page of this site:

• Test first, sell second. If a free state test kit is the right next step, that's the advice you'll get. Two-thirds of the houses in this state test high; there's no need to oversell the third that doesn't.
• ANSI/AARST or it doesn't count. North Dakota doesn't license radon work, so the national consensus standards are the only real bar. That's the bar.
• Every install is verified. A system without a post-mitigation test is a claim, not a fix. The follow-up test is included, and the number is yours in writing.
• Firm written pricing. Quotes come before work, in writing, with no in-home sales theater.

Why This Market Needed the Site

Bismarck sits in the middle of the worst radon geology in the lower 48 — 63 percent of North Dakota homes test above the action level, every county in the state is EPA Zone 1, and the state's own Radon Control Program is headquartered in this town. And yet radon here has mostly been handled as an afterthought: a checkbox at closings, a brochure at the health unit. With North Dakota's radon disclosure law now in effect, every home sale in Burleigh and Morton counties has to answer the radon question in writing. This site is the local, plain-English answer to it — the geology, the costs, the law, and the fix, all in one place, with a phone number that gets answered.
