Radon testing & mitigation in West Virginia

This site imports no West Virginia state roster, so these are current NRPP and NRSB certifications from those programs’ public finders. A national certification is not a state license. We group people by the city on that file. We do not invent neighborhoods. Source: NRPP.

How to verify a radon credential in West Virginia

WV DHHR licenses radon work in West Virginia but publishes no list with credential numbers that we can import, so listings here are national NRPP or NRSB certifications instead. A national certification is not the West Virginia credential. Ask the agency directly: Request the licensee list from WV DHHR.

Questions about radon credentials in West Virginia

Does West Virginia license radon testers and mitigators?

Yes. WV DHHR licenses radon work in West Virginia. It publishes no current list with credential numbers that we can import, so this site cannot show the West Virginia credential itself.

How do I verify a radon credential in West Virginia?

Ask WV DHHR directly: Request the licensee list from WV DHHR. The 51 listings shown here are current NRPP or NRSB certifications, which you can check on those programs' public finders, but they are not the West Virginia credential.

Is an NRPP or NRSB certification enough in West Virginia?

No. West Virginia credentials radon work separately through WV DHHR. A national certification does not satisfy that requirement. Ask any provider for their West Virginia credential and verify it with the agency before you hire.
