Who may remove mold in West Virginia

No mold license — checked, not assumed

A handful of states license mold work directly. West Virginia is not one of them. The Bureau for Public Health's list of licensing programs covers asbestos abatement, lead abatement, radon mitigation, clandestine drug laboratory remediation, well drillers, water and wastewater plant operators and several others. Mold is not on it.

The Legislature has looked at the subject. House Bill 4351, introduced on January 15, 2026, would have had the state's public health department set up registration for mold remediation firms, with proof of financial responsibility and at least one supervisor holding a third-party certification, and would have required work to follow the ANSI/IICRC S520 standard. Its last recorded action is referral to the House Health and Human Resources committee that day. It did not become law.

What that means in practice: any company in Jefferson County can call itself a mold remediator. Advertising that points to a state mold license describes a credential that does not exist here, and is a reason to ask what, exactly, is licensed.

The license that does apply

West Virginia's Contractor Licensing Act defines a contractor as anyone who, for pay and not as someone else's employee, undertakes to build, alter, repair, improve or demolish a structure "where the cost of the undertaking is $5,000 or more for residential work." A mold job in a Ranson house — tearing out drywall and insulation, drying the framing, putting the wall back — routinely crosses that line.

Contracting without a required license can bring a cease and desist order and a penalty of $200 to $1,000 from the board, and continuing after the order is a misdemeanor. The board's site has a public license search; it takes a minute.

Two exceptions in the definition matter to an owner. A person working on their own property is not a contractor under the Act. And a firm that only cleans — with no cutting out or rebuilding — may stay under the threshold. Ask how the job is scoped.

Where other state licenses come in

Mold work in an older house can disturb materials that are regulated even though mold is not:

• Asbestos. The Bureau for Public Health licenses asbestos abatement. If a contractor plans to remove old flooring, pipe insulation or other materials in a house of an age where they may contain asbestos, ask whether anything will be tested before it is disturbed.
• Lead paint. In homes built before 1978, federal rules require anyone paid to disturb painted surfaces to be certified in lead-safe work practices. In Shepherdstown and Harpers Ferry most of the housing is that old — more on older houses.

What to ask, given all this

Because there is no mold credential to check, the useful questions are about method and the general license: the West Virginia contractor license number and the name it is held under, whether the crew follows a written standard (S520 is the industry's), how the area will be closed off, and how drying will be confirmed before the wall is closed.
