Asbestos licensing in Pennsylvania

Pennsylvania requires asbestos abatement contractors to hold a license from the Department of Labor & Industry, and requires people working inside containment to hold department certification. Workers who remove asbestos must work for a certified contractor. The department posts lists of certified contractors and individuals on its asbestos occupations page, so you can check the certification on record. Rules for a homeowner's own work are unclear, so check the agency's site for current requirements.

Mold licensing in Pennsylvania

Pennsylvania has no state license or certification for mold inspectors or remediators, and the Department of Health says there are no federal or state mold regulations. Contractors who do home improvement work for $5,000 or more in a year generally must register with the Attorney General, who runs a lookup for that registration. Some cities may have local rules. Check the state and your local government's sites for current requirements.
