Short answer
Radon professionals in Michigan, in brief
No business that Michigan itself licenses or certifies is listed on Radon411 yet. Michigan's radon program says the state does not license or certify radon professionals.
6 businesses with an address in Michigan appear in a separate list because another state's registry lists them. That does not mean Michigan licenses them.
The rule
Does Michigan license radon professionals?
No. Michigan's radon program page, checked on September 25, 2026, says:
Michigan does not license or regulate radon testing and mitigation contractors.
Michigan is not on the list of states with radon credentialing programs that EPA's state contacts page publishes. 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.
Radon411 reads no licensing list for Michigan; Michigan's radon program is the place to ask who works there.
