Mold Remediation in New Jersey: common questions
Is mold remediation licensed in New Jersey?
New Jersey 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 New Jersey, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do New Jersey mold remediation firms actually hold?
Across the 236 New Jersey firms on file for this work, the most common credentials are WRT (Water Damage Restoration Technician) held by 101 firms, AMRT (Applied Microbial Remediation Technician) held by 94 firms, ASD (Applied Structural Drying Technician) held by 87 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 73 firms. 92 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.
How were these New Jersey firms verified?
Every certification was checked against IICRC's own Certified Firm registry, not against the firm's marketing. 27 of the 236 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026.
