Licensed Asbestos Abatement Companies in Pennsylvania

Pennsylvania licenses asbestos abatement contractors through the Pennsylvania Department of Labor & Industry under the state Asbestos Occupations Accreditation and Certification Act. With row homes, mills, and schools dating back a century or more — and two major metro markets in Philadelphia and Pittsburgh — Pennsylvania has one of the largest licensed asbestos workforces in the country. The 279 firms below are all verified against the Department’s current license list.

All 279 firms verified against the official PA Department of Labor & Industry register as of July 2026.

• Verify the license. Every firm on this page is verified against the PA Department of Labor & Industry register, and each listing shows the license number so you can check it yourself.
• Match the license to the job. Use an abatement contractor for removal or repair, and an independent testing & inspection firm for surveys, sampling, and clearance air testing.
• Get at least three written quotes. A proper quote details the scope of work, containment method, waste disposal, and final clearance testing.
• Ask about insurance. Licensed firms should carry general liability and, for abatement, pollution liability coverage. Request certificates before work starts.
