Radon mitigation in Grand Forks, North Dakota
Radon testing and systems for houses across North Dakota's third-largest city, from older blocks near downtown and UND to the newer south end.
Grand Forks is the county seat of Grand Forks County and North Dakota's third-largest city, with 59,166 residents at the 2020 census. It sits on the west bank of the Red River of the North, at the fork where the Red Lake River comes in, and it's home to the University of North Dakota, the state's oldest university, founded in 1883. The whole Red River Valley is the floor of glacial Lake Agassiz, which is why the land around the city is so flat.
Which houses here need a closer look?
All of them, since ND DEQ reports 63 percent of North Dakota homes above the action level. But some situations come up a lot in Grand Forks: older homes in the Near Southside and the blocks between downtown and campus, with block or stone foundations and patched floors; houses repaired, raised or replaced after the 1997 flood; and newer south-end homes with finished basements, where the pipe has to be routed neatly.
Common radon jobs in Grand Forks
- Sub-slab systems in full and partial basements
- Combination systems where a crawl space addition meets the basement
- Interior pipe runs through a garage or closet in finished-basement homes
- Testing and systems on real estate timelines, including rentals near UND

Landlords and rentals
With a large university in town, many Grand Forks houses are rentals. Testing protects tenants and gives you documentation. Ask the radon company for written results and keep them with the property records.
