Mold Remediation & Assessment in Louisiana

38 certified mold remediation firms on file in Louisiana, including 1 holding a current Louisiana mold licence. Credentials below are verified against the State Licensing Board for Contractors (LSLBC) and IICRC's Certified Firm registry.

Louisiana licenses mold work. Companies and individuals must be licensed for mold remediation projects of $7,500 or more (project value, not square footage). A licensed mold remediation contractor may not “perform both mold assessment and mold remediation on the same property”, nor own an interest in both the assessing and the remediating entity — La. R.S. 37:2158(A)(23)(c)–(d). Unlike Texas and Florida, Louisiana licenses no mold assessors: the duty rides on the remediation licence, which is only required where the project value reaches $7,500, so below that figure neither the licence nor the separation rule attaches.

Mold Remediation in Louisiana: common questions

Do I need a licensed mold remediation contractor in Louisiana?

Louisiana requires a licence for mold remediation projects of $7,500 or more (project value, not square footage) (La. R.S. 37:2150.1(4)(a)(iv)), issued by State Licensing Board for Contractors (LSLBC). A licensed mold remediation contractor may not “perform both mold assessment and mold remediation on the same property”, nor own an interest in both the assessing and the remediating entity — La. R.S. 37:2158(A)(23)(c)–(d). Unlike Texas and Florida, Louisiana licenses no mold assessors: the duty rides on the remediation licence, which is only required where the project value reaches $7,500, so below that figure neither the licence nor the separation rule attaches.

What certifications do Louisiana mold remediation firms actually hold?

Across the 38 Louisiana firms on file for this work, the most common credentials are WRT (Water Damage Restoration Technician) held by 38 firms, AMRT (Applied Microbial Remediation Technician) held by 37 firms, ASD (Applied Structural Drying Technician) held by 33 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 30 firms. 34 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.

How were these Louisiana firms verified?

Every certification was checked against IICRC's own Certified Firm registry, and every licence against the State Licensing Board for Contractors (LSLBC) file, not against the firm's marketing. 3 of the 38 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026. Where a state publishes only current licensees, a firm absent from that file is reported as absent — never as unlicensed.
