15 certified mold remediation firms in Jacksonville, FL
Ordered by verified credentials only — cross-verified firms first, then active state licences, then breadth of certification. Payment never affects this order.
Yes. Florida requires a licence for 10 square feet — definitional: work at or below 10 sq ft is not “mold remediation” as the statute defines it (§468.8411, Fla. Stat.). Verify any licence at the official lookup. Also: A licensed assessor may not remediate — and a remediator may not assess — the same structure within 12 months, in either direction, and the bar reaches the licensee's company: §468.8419(1)(d), (2)(d), Fla. Stat. Note the express carve-out in both paragraphs for a certified contractor classified as a Division I contractor under §489.105(3), which is broad enough that many general contractors fall outside the bar entirely.
Can my mold inspector also do the remediation?
4 of the 5 licensing jurisdictions bar the same party from assessing and remediating the same property or project: Texas, Florida, New York and Louisiana. District of Columbia does not — the rule there is disclosure of conflicts and a bar on working where the licensee has a financial interest, not a prohibition on holding both roles. Where no mold licence exists, nothing stops one firm doing both — using an independent assessor is then your own protection against a contractor writing the scope of work they will be paid to perform.

Housing here
422,355 housing units in Jacksonville city, Florida, of which 41% were built before 1980. 43% of occupied homes are rented.
Why this is on the page: older housing has had longer to accumulate water events, and its plumbing and building envelope are closer to end of life — so age is a reasonable proxy for how often local firms meet older construction, not a statement about any individual property. It does not mean older homes have mold. With 43% of homes rented, a large share of water and mold problems here are a landlord repair duty before they are a contractor decision.
