Mold Remediation in Pennsylvania: common questions
Is mold remediation licensed in Pennsylvania?
Pennsylvania does not run a mold-specific licensing program. Only five US jurisdictions do (Texas, Florida, New York, Louisiana and the District of Columbia; Illinois has enacted a program that is not yet in force). In Pennsylvania, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do Pennsylvania mold remediation firms actually hold?
Across the 119 Pennsylvania firms on file for this work, the most common credentials are AMRT (Applied Microbial Remediation Technician) held by 112 firms, WRT (Water Damage Restoration Technician) held by 112 firms, ASD (Applied Structural Drying Technician) held by 95 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 86 firms. 108 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.
How were these Pennsylvania firms verified?
Every certification was checked against IICRC's own Certified Firm registry, not against the firm's marketing. 3 of the 119 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026.
