Radon mitigation in Moorhead, Minnesota
Radon tests and MDH-licensed mitigation across the river from Fargo, from homes near MSUM and Concordia to newer houses on the south side.
Moorhead is the county seat of Clay County, Minnesota, with 44,505 residents at the 2020 census. Platted in 1871 and named for a Northern Pacific Railway official, it sits on the east bank of the Red River directly across from Fargo. Minnesota State University Moorhead and Concordia College are both here.
Minnesota rules for Moorhead homes
- Anyone who designs or installs a mitigation system in a house they don't own needs an MDH radon mitigation license, and the company needs an MDH company license.
- A professional who tests a house they don't own needs an MDH measurement license.
- Every professionally installed system carries an MDH tag inside the house next to the pressure gauge.
- You get an operation, maintenance and monitoring plan for the system.
- Fan wiring must meet Minnesota Department of Labor and Industry rules.
Homes built since 2009
MDH says new Minnesota homes have had to be built radon-resistant since 2009, with a passive vent pipe from under the slab through the roof and an attic junction box for a future fan. If your newer Moorhead house tests high, activating that pipe is often the simplest fix.
Selling in Moorhead?
The Minnesota Radon Awareness Act requires sellers to disclose what they know about radon in writing before a purchase agreement is signed and to hand over MDH's "Radon in Real Estate Transactions." It doesn't require a test. Many sellers test anyway, so the numbers are known before buyers ask.
College-area rentals
With two colleges in town, Moorhead has plenty of rentals. Landlords who test and keep written results have something concrete to show tenants.
Common questions
Does a Moorhead radon installer need a license?
Yes. Minnesota requires an MDH license to design or install a mitigation system in a building you don't own or lease.
How can I check that my Moorhead system was done by a licensee?
Look for the MDH tag next to the pressure gauge, and ask the installer for their license and the OM&M plan.
