Short answer

Radon professionals in Hawaii, in brief

No business that Hawaii itself licenses or certifies is listed on Radon411 yet. Ask Hawaii's radon program what it requires before you hire.

The rule

Does Hawaii license radon professionals?

Radon411 holds no checked reading of Hawaii's radon program page yet, so this page states no licensing rule for Hawaii. Ask the program before you hire.

Hawaii 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.

State program

Hawaii's radon program

The state's own radon program: the place to ask who may work in the state.

Radon411 has not checked Hawaii's radon program page yet, so it states nothing about the program here.

How to check a credential in Hawaii

  1. Hawaii's own list

    Start with Hawaii's radon program. Licensing is done by the state, and most states can give you a list of radon service providers working there.

  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

A tester
