Licensing in Washington

Asbestos licensing in Washington

Washington's Department of Labor & Industries certifies asbestos abatement contractors, supervisors and workers. If materials with asbestos could be disturbed, the department says to hire a certified asbestos contractor, and it requires a survey by an AHERA-certified building inspector before remodeling, repair or demolition work. L&I publishes a certified contractors list and an online contractor lookup. Check the certificate on record, and check the agency's site for current requirements.

Mold licensing in Washington

Washington does not have a state certification for mold or water damage remediation, and the Department of Health notes that anyone can call themselves a mold specialist. The state does register construction contractors, and it suggests choosing one that is registered, bonded and insured and checking for past violations. Industry groups such as IICRC offer voluntary certification. Ask for credentials in writing, and check state sites for current requirements.

Lead licensing in Washington

Washington runs its own lead-safe programs through the Department of Commerce. A firm that renovates, repairs or paints a home built before 1978 needs Washington RRP certification, and work such as lead inspections, risk assessments and abatement needs a separate lead-based paint activities certification. Commerce publishes a list of certified businesses on its resources page. Check the certification on record, and check the agency's site for current requirements.

Radon licensing in Washington

We did not find a Washington state license or certification specific to radon testing or mitigation. The state Department of Health recommends hiring a certified radon professional through the national certification programs, or a general contractor who meets state requirements and can hire one. Ask to see current credentials, and check the Department of Health and L&I sites for requirements before hiring.
