Florida Mold-License Data 2026: The July 31 Renewal Cliff

Florida is one of the few states that licenses mold work and publishes the full registry — which means the size and shape of the profession is a matter of public record, not guesswork. We pulled the state's own Board 07 licensee extract on July 25, 2026 and again on August 4, 2026, and counted both. The picture turns on one fact: the entire field renews on the same clock — July 31 of every even-numbered year, which for this cycle meant July 31, 2026, with the following cycle ending July 31, 2028.

That deadline has now passed, so this page reports both sides of it — what the register looked like going in, and what it looks like coming out.

The headline: the register lost 2,473 licenses

Florida's mold profession is close to a third smaller on paper than it was two weeks ago. On the July 25 extract there were 8,079 current mold-related services licenses. On the August 4 extract — the first reading after the deadline — there are 5,606. That is a net loss of 2,473 current licenses, about 31%, and it lands almost entirely on the licensees who were facing the July 31 date.

Tracking the individual license numbers across the two extracts shows what happened to each of the 3,328 licenses that carried a July 31, 2026 expiration: 840 renewed through 2028, and 2,488 did not and no longer read as current. That is a renewal rate of just over one in four. Fifteen newly issued licenses arrived in the same window, which is why the register fell by 2,473 rather than the full 2,488.

The two license types behaved almost identically, which argues against reading this as a problem specific to either half of the job: of the assessors facing the deadline 26.1% renewed, against 24.4% of the remediators.

What the register looked like going in

Before the deadline the picture was the mirror image. There were 8,079 current licenses — 4,084 Mold Assessor (MRSA) and 3,995 Mold Remediator (MRSR) — of which 3,328, about 41%, were set to expire on July 31, 2026, with the other 4,751 already renewed through July 31, 2028. Every renewing license shared that single date; Florida runs mold licensing on a two-year cycle that ends every even-numbered year on July 31, so there are no staggered anniversaries to spread the load.

How the 3,328 figure moved before the deadline

The 3,328 figure is a moving number, and it moved down fast in the run-up to the deadline. On the June 23 state extract, 5,112 licenses were set to expire in 2026; by July 7 it was 4,573, by July 14 4,167, by July 20 3,768, and by our July 25 reading it had fallen to 3,328 — meaning roughly 1,784 professionals renewed early between late June and July 25, about 440 of them between July 20 and July 25 alone. That was the crest of the renewal wave, and it turned out to be most of the renewing that happened: only 840 more licenses moved to a 2028 expiration between July 25 and the deadline itself.

The count that ultimately matters to a homeowner is not how many renewed early but how many let the date pass, and that only shows up in the registry afterward. It now has: 2,488. One important caveat on that number — a lapsed license is not immediately a dead one. Under §455.271 of the Florida Statutes it first turns delinquent, and the licensee can reinstate it during the current two-year cycle by paying a delinquency fee, a reactivation fee, and the renewal fees; only a license left delinquent through the end of the cycle becomes null and void. So expect some of the 2,488 to return to the rolls over the coming months. What does not change is the practical reading for anyone hiring today: delinquent and null and void mean the same thing at the point of hire — the contractor is not currently authorized to perform regulated mold work.

Where Florida's mold pros are — and aren't

Licensing is heavily concentrated, and the deadline did not change that. Three Southeast Florida counties — Broward (812), Miami-Dade (777), and Palm Beach (518) — together hold about 38% of every licensed professional in the state, almost exactly the share they held before the renewal cycle. Broward's 812 is the deepest bench in the state, and it is almost evenly split — 403 assessors and 409 remediators — so neither half of the job is the scarce one there; the mold removal companies serving Fort Lauderdale are listed with each firm's service class and the credential we checked, dated to the month we checked it. Miami-Dade's 777 is a close second and worth using the same way: you can compare license-checked mold companies across the Miami metro instead of taking whichever firm answers first. Palm Beach's 518 divide exactly evenly — 259 assessors and 259 remediators — so a household there that needs the assessment and the remediation done by different firms is drawing from two lists of the same size; the licensed mold remediation companies serving West Palm Beach are listed with each firm's service class and the credential we checked, dated to the month we checked it. At the other end, eight counties now have zero licensed mold assessors or remediators with a local address of record: Gulf, Hamilton, Lafayette, Madison, Taylor, and Union, which were already empty, plus Dixie and Glades, which each went into the deadline with a single licensee and came out with none. Seven more counties have two or fewer.

That does not mean no one will service those counties — a licensee headquartered in Tallahassee or Gainesville can and does travel — but it does mean residents there are choosing from a very thin local bench, which makes verifying the one or two names they are offered all the more worth doing. Seven of those eight counties sit in North Florida, which makes the capital their practical hiring market: Leon came out of the deadline holding 31 licensed professionals — 13 assessors and 18 remediators — so a household that needs the assessment and the remediation done by different firms is drawing from two lists of that size. Checking which mold assessors and remediators are licensed out of Tallahassee is the shortest way to see who those firms are, and the Leon County firms whose DBPR license we have checked are listed with the class each one holds. The western Panhandle is a separate market rather than an extension of that one. Pensacola sits at the far western end of the state, nearly 200 miles from the capital, and the bench a household there hires from is Escambia's 38 alongside Santa Rosa (30), Okaloosa (22) and Walton (19) — four rows that read as one field in practice, so it is worth opening the Escambia-area mold companies we check against the DBPR registry against those neighboring counties rather than against the Leon figure. Within that field the two halves of the job are not equally deep: Okaloosa's 22 divide 8 assessors to 14 remediators, so the independent assessment §468.8419 requires from a separate firm is the scarcer engagement at that end of the coast. A Crestview, Destin or Fort Walton Beach household can read which of the Okaloosa County firms assess and which remediate before deciding which call to make first.

Concentration also reads differently where a single market is split across county lines. Tampa Bay's bench sits in three counties rather than one: Hillsborough (308), Pinellas (244), and Pasco (161) hold 713 licensed professionals between them, close behind Miami-Dade's 777. Someone in Wesley Chapel or New Port Richey who reads the Pasco row on its own would undercount the field available to them by a wide margin, so it is worth weighing the verified mold contractors in Pasco County against the DBPR-checked assessors and remediators based in Hillsborough County, who work the metro as a matter of course. Pinellas sits between the two and divides exactly evenly — 122 assessors and 122 remediators — so a St. Petersburg or Clearwater household that needs the assessment and the remediation done by different firms is drawing from two lists of the same size; the Pinellas County mold companies we have checked against the DBPR registry are listed with the license class each firm holds. Central Florida reads the same way. Orange (265) is the fifth-largest county bench in the state on its own, but the Orlando–Kissimmee–Sanford metro that hires from it also takes in Seminole (125), Osceola (85) and Lake (84) — 559 licensed professionals across the four, of which the Orange row alone is under half. A household in Kissimmee or Sanford reading only its own county's line is looking at a fraction of the market it can actually hire from, so it is worth opening Orange County's own list of license-checked assessors and remediators alongside the neighboring rows rather than in place of them. That four-county field is how the directory is built, too: the mold companies serving the Orlando metro are listed from Orange, Seminole, Osceola and Lake together, each with the service class it holds and the month we checked it, so the list matches the market a Kissimmee or Sanford household actually hires from rather than the county line it happens to sit behind.

The full county-by-county count follows, on the August 4 reading, with each county's change across the renewal deadline. County reflects each licensee's address of record with the state, so read it as "licensed professionals headquartered here," not "licensed professionals who will work here."

The table also rewards reading by proportion rather than by raw count. Sarasota County, for one, went into the deadline with 142 licensed professionals of record and came out with 92 — a net loss of about 35%, above the statewide 31% — leaving 48 assessors and 44 remediators for a metro of that size. Where local attrition ran above the state average, a larger share of the firms a homeowner was referred to a year ago no longer reads as current, so an old recommendation is worth re-checking: you can see which Sarasota mold remediators still hold an active MRSR license before you shortlist anyone, or start from who still holds an active mold license in Sarasota County if the firm you were given works the wider county rather than the city.

Assessors, remediators, and the out-of-state share

The field still splits almost evenly between the two license types — 2,875 assessors and 2,731 remediators on the August 4 reading, against 4,084 and 3,995 before the deadline — which reflects Florida's independence rule: under §468.8419 the same person generally cannot both assess and remediate the same property within 12 months, so the two roles are held and licensed separately. For a household that is a budgeting fact as much as a legal one: the assessment is its own engagement with its own invoice, and a standalone mold inspection in Florida runs about $230 to $785, typically near $450, before a single remediation quote is written. That the ratio barely moved through a renewal cycle this severe is itself worth noting: the lapses were spread across the profession rather than concentrated in one half of the job.

A profession that grew fast

Florida's licensed mold workforce is young and expanded quickly. New mold-related services licenses issued per year rose from 167 in 2016 to a peak of 766 in 2024:

A fast-growing, recently-licensed field is exactly the kind where a badge on a website can outrun the license behind it, and a Florida mold license and a mold certification prove different things — which is the case for checking the record rather than the marketing.

What this means if you are hiring

The single most useful takeaway is timing, and it is no longer hypothetical. A license confirmed earlier in 2026 may well have changed status on July 31 — 2,488 of them did. A contractor who was current in June can read delinquent today even though their truck, website, and old paperwork still say "licensed," which makes a check done this spring worth repeating rather than trusting. Hiring a contractor whose license has lapsed can also complicate an insurance claim later, since a carrier may question whether the work was performed by a properly licensed operator.

You do not have to take any of this on trust. Before you sign, verify the contractor's Florida license — our free tool reads the live DBPR record and shows whether the license is current and active today, its type, and the date we checked it. If you are researching the credential itself, see how a Florida mold license is earned and how renewal works.

Methodology: Figures are tabulated from the Florida Department of Business and Professional Regulation, Division of Professions, Mold-Related Services (Board 07) public licensee extract (lic07mold.csv), retrieved July 25, 2026 and again August 4, 2026. We count the two consumer-facing license types — Mold Assessor (MRSA) and Mold Remediator (MRSR) — and treat a license as "current" when its DBPR primary status is Current. "Expiring July 31, 2026" means a July 31, 2026 expiration date on a current license. Renewed-versus-lapsed counts are computed by matching individual DBPR license numbers across the two extracts rather than by subtracting totals, so a license is counted as renewed only where the same license number appears in the August file as current with a July 31, 2028 expiration; the two figures reconcile against the statewide totals (8,079 − 2,488 + 15 newly issued = 5,606). A license that no longer reads as current has lapsed into delinquent status under §455.271 and may be reinstated within the cycle, so these counts are a floor on eventual renewals rather than a final tally. County reflects each licensee's address of record with DBPR, not a service area; the county table covers the 5,181 current licensees with a mapped Florida county on the August 4 extract, while statewide totals additionally include out-of-state and unmapped licensees. Figures are a point-in-time snapshot and change as licensees renew; we refresh from the state extract weekly. No estimates or projections are used.
