Radon professionals in Minnesota

Who tests and fixes radon in Minnesota, what Minnesota's own program says about licensing, and how to check a credential before you hire.

Updated October 2, 2026

Short answer

Radon professionals in Minnesota, in brief

No business that Minnesota itself licenses or certifies is listed on Radon411 yet. Minnesota's radon program says the state licenses or certifies radon professionals.

7 businesses with an address in Minnesota appear in a separate list because another state's registry lists them. That does not mean Minnesota licenses them.

The rule

Does Minnesota license radon professionals?

Yes. Minnesota's radon program page, checked on September 25, 2026, says:

The Radon Licensing Act requires anyone who performs a radon test or radon mitigation, in a building they do not own or lease, must be licensed by MDH.
MDH Indoor Air Unit, read September 25, 2026

EPA's state contacts page lists Minnesota among the states with radon credentialing programs. Licensing is done by the state, not by the national programs, and EPA requires states that receive radon grants to give the public a list of only those providers credentialed by the state or by NRPP or NRSB.

Minnesota does not publish a list of licensed radon professionals that Radon411 can read, so the state's own search is the complete source.

Before you hire

How to check a credential in Minnesota

  1. Minnesota's own list

    Start with the Minnesota Department of Health. Licensing is done by the state, so its list or search says who may legally work in Minnesota.

  2. NRPP's search

    The National Radon Proficiency Program's search finds its Certified Mitigation Specialists and Certified Measurement Professionals by area, by name, or by the 6-digit NRPP ID number a professional can give you.

  3. NRSB's search

    The National Radon Safety Board's search finds a professional in your area, or confirms that a named professional is NRSB certified.

  4. The ID card

    The programs usually issue a photo ID card showing the holder's qualifications and its expiry date. Ask to see it, and if in doubt, check with the body that issued it.

Hiring

Hiring in Minnesota

A tester

Ask for the credential and ID card, how the test will be guarded against interference, and when the report will come. EPA recommends an independent, qualified tester for the test after a system is installed.
