Mold Remediation in Massachusetts: common questions
Is mold remediation licensed in Massachusetts?
Massachusetts 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 Massachusetts, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do Massachusetts mold remediation firms actually hold?

Certification describes verified training rather than the services a firm chooses to advertise.

Every certification was checked against IICRC's own Certified Firm registry, not against the firm's marketing. 5 of the 63 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026.
