The rule most consumers don't know
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.
In plain terms: the person who inspects your mold problem cannot be the person you pay to fix it. The assessor writes the protocol; an independent remediator executes it. This protects you from a contractor inventing work for themselves — and it is the law in every US jurisdiction that licenses mold work.
Worth knowing right now
Louisiana rewrote its contractor law twice in two years: Act 422 (eff. 1 Aug 2025) and Act 757 (eff. 1 Aug 2026) both restructured licensing, insurance and enforcement provisions, and the board's published rules have not yet been conformed. Section numbering shown here derives from the enrolled acts and is re-verified against the code as it is republished.
