West Virginia licenses radon testers, mitigation specialists, mitigation contractors, and radon laboratories under OEHS RTIA (W. Va. Code §16-34). Names, addresses, phones, license numbers, counties, and expiration dates are transcribed from the official RTIA Licensing Search — nothing invented. Address of record and county follow the source as printed (including out-of-state licensees). Status changes; re-check OEHS before hiring.
This page covers indoor air only. Free resident kits: email Radon@wv.gov or call 304-352-5039 (OEHS Radon Program).
Always verify the license is still current with OEHS before hiring. This index does not rank contractors or take referral fees.
