How it works
Call or send a request
Tell us the town and the situation: no test yet, a high number, a home sale, a crawl space, or a system that stopped pulling.
We connect you
Your request goes to an independent radon company that covers your part of the Minot area.
They call you back
That company follows up, looks at the house and gives you its own proposal for testing or a system.
Who is this for?
Homeowners, buyers, sellers and landlords in Minot and the nearby Ward County towns of Burlington and Surrey. If a house has a basement, a crawl space or a slab on the ground, soil gas can get in. Radon has no color, smell or taste, so a test is the only way to learn what your level is.
Is radon a real problem around Minot?
Yes. The numbers from state and federal agencies are hard to ignore.
- Statewide levels: The North Dakota Department of Environmental Quality (DEQ) reports that about 63 percent of the state's homes test above the EPA action level of 4.0 picocuries per liter (pCi/L).
- Every county is high-potential: DEQ notes North Dakota is one of only two states where all counties, Ward County among them, fall in EPA Zone 1, the highest of the EPA's three radon zones.
- Why it matters: The EPA estimates about 21,000 lung cancer deaths a year in the U.S. are tied to indoor radon. DEQ says lung cancer is the only health effect firmly linked to it, and that it typically shows up 5 to 25 years after exposure.
Those are state figures, not a forecast for your house. Neighbors on the same street can get very different results, so each home needs its own test.
How does radon get inside?
Radon forms as uranium in soil and rock breaks down, then works its way up through the ground. DEQ lists the usual ways in: cracks in the slab, the joint where the floor meets the wall, pores and cracks in block or poured walls, open block-wall tops, exposed soil in a sump, drain tile that empties into an open sump, mortar joints and loose gaps around pipes. Minot winters make the pull stronger. The city's record low is 49 below zero, and January nights average about 4°F, so for months the furnace runs, the windows stay shut and the house draws air in at the bottom as warm air escapes at the top.
Does it matter whether I live in the valley or on the hill?
Not for whether you should test. Minot is split into North Hill, South Hill and the Mouse River valley between them, which sits roughly 160 feet below the surrounding plains. Valley neighborhoods like Eastwood Park, Oak Park and West Minot took the brunt of the 2011 flood, and many basements there were repaired afterward. Hill or valley, every house sits on Ward County ground, and all of it should be tested.
How should I test?
Use a kit labeled EPA approved, which DEQ says you can find at hardware and big box stores and online. DEQ's residential testing guidelines call for placing the device in the lowest livable area, at least 20 inches off the floor, away from drafts, exterior doors, heat sources and humid rooms, and at least 10 feet from an unsealed sump. Close outside windows and doors 12 hours before the test and keep them closed until it ends. For a sale, or if you'd rather not do it yourself, a radon professional can run a continuous monitor. More on our radon testing page.
Can I get a free test kit from the state?
Not right now. DEQ handed out a limited supply of free kits during its January 2026 Radon Action Month campaign, and its radon page now says it is out of free kits. Store-bought kits are the option until DEQ restocks.
My number is high. Now what?
The EPA recommends fixing a home at 4.0 pCi/L or above. DEQ says sealing cracks and sump lids can lower levels, but those seals need ongoing upkeep, and a radon reduction system is the most effective permanent fix. In a Minot basement home, that's usually sub-slab depressurization: a suction pit under the floor, sealed pipe, and a fan that runs nonstop and vents above the roof. Houses on crawl spaces get a sealed plastic membrane with suction under it. See radon mitigation systems and crawl space radon systems.
Who is allowed to install a radon system in North Dakota?
DEQ says a homeowner may install a system or hire an installer, and it publishes a list of radon mitigation and measurement people located in the state. DEQ's radon materials don't describe a separate state radon license. North Dakota's general contractor license, issued by the Secretary of State, applies to any job over $4,000. Our Minot radon guide covers the details and how to check a license.
What does a radon system cost in Minot?
It depends on the foundation, how easily air moves through the fill under the slab, how many suction points are needed, and whether the pipe can run through a garage or has to go up an outside wall. The company you're connected with sets the price after seeing the house.
Are you a radon company?
No. Minot Radon Removal is a referral service. We pass your call or form to an independent radon company that serves your address, and that company handles the testing, proposal, installation and warranty. Before you hire, read our tips for choosing a radon contractor.
