Radon mitigation in East Grand Forks, Minnesota
Radon testing and MDH-licensed mitigation for homes north of the Red Lake River and down on The Point.
East Grand Forks is across the Red River from Grand Forks and is the largest community in Polk County, Minnesota, with 9,176 residents at the 2020 census. The Red Lake River runs through town and meets the Red River here; the main part of the city, with downtown and the oldest neighborhoods, is north of the Red Lake River, and the area to the south is called The Point.
A rebuilt city
In 1997 the whole city was under mandatory evacuation, and nearly every home was damaged. Several neighborhoods were later cleared for the Greenway and new dikes. Many houses here have newer foundations, rebuilt basements or post-flood additions. That's a good reason to test even if a previous owner did years ago.
Minnesota rules apply here
- The installer must hold an MDH radon mitigation professional license and work for a licensed mitigation company.
- Every professionally installed system gets an MDH tag next to the pressure gauge.
- You should get an operation, maintenance and monitoring plan for the system.
- Sellers must give buyers a radon disclosure under the Minnesota Radon Awareness Act.
Newer homes and passive pipes
MDH says all new Minnesota homes have been required to be built radon-resistant since 2009, with a passive vent pipe from below the foundation through the roof and a junction box roughed in the attic. If your home has one and still tests high, adding a fan can turn it into an active system.
Common questions
Is a radon contractor in East Grand Forks required to be licensed?
Yes. Minnesota requires an MDH license to install or design a radon mitigation system in a building you don't own or lease.
How can I tell if my system was installed by a licensed pro?
Look for the MDH tag next to the pressure gauge and ask for the installer's license and paperwork.
