Short answer

Radon professionals in Maine, in brief

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

The rule

Does Maine license radon professionals?

Yes. Maine's radon program page, checked on October 3, 2026, says:

Under Maine law, only the owner or occupant of a residence or someone registered with the state to provide these services, may test for radon, install and/or advise on the installation of a radon reduction (mitigation) system.

EPA's state contacts page lists Maine 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.

Before you hire

How to check a credential in Maine

  1. Maine's own list

    Start with the Maine Center for Disease Control and Prevention, Radiation Control Program. Licensing is done by the state, so its list or search says who may legally work in Maine.

  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.
