Florida licenses mold assessors and mold remediators as two separate jobs through the Department of Business and Professional Regulation. Licensing applies to mold areas above about 10 square feet, and an assessor may not remediate a structure it assessed within the previous 12 months. To check a company, ask for its DBPR license number and look it up.
Key takeaways
- Florida licenses mold assessors and mold remediators as two separate license types, and each requires an examination the state approves.
- The licensing rules are framed around mold areas above about 10 square feet, a line the rule text describes as an approximation.
- An assessor may not remediate a structure it assessed within the previous 12 months, and a remediator may not assess one it remediated in that period.
- Any homeowner can check a mold company's license by asking for its DBPR license number and looking it up on the state's website.
- The EPA's practical targets are indoor humidity below 60 percent and wet materials dried within 24 to 48 hours where possible.
- Lakeland's rainy season runs from late May into early October, with 55 to 70 percent of the year's rain typically falling June through September.
What does Florida actually license for mold?
The Department of Business and Professional Regulation licenses two mold-related roles: assessor and remediator. Both are set out in Chapter 468, Part XVI of the Florida Statutes and Rule Chapter 61-31 of the Florida Administrative Code.
An assessor investigates a building for mold, identifies where growth is and writes up what it finds. A remediator removes or treats the mold itself. The two are separate license types, and each requires passing an examination the department has approved. The exams are given by outside organizations rather than by the department directly, so the license a person holds tells you which role they are qualified to perform.
The distinction matters on a real job. An assessment is a written finding about where mold is and how far it reaches. Remediation is the physical work of removing it. Florida treats these as separate jobs, and the law keeps the two roles apart so that one company does not grade its own cleanup.
Where does the 10-square-foot line fall?
Florida's licensing rules apply to mold areas above about 10 square feet. The figure is a reference point in the rule, not a rule of thumb for deciding whether a patch needs attention.
Rule 61-31.102 frames the assessor examination around amplified mold growth over about 10 square feet, and the remediator examination around removing or treating mold over that size. The word that matters is about. The ten-square-foot figure is the threshold the licensing scheme is built around, and the rule text is the thing to check if you need the exact wording.
Surface size is also an imperfect guide. What shows on a wall or ceiling is often a fraction of what sits behind drywall or under flooring, so a small visible patch in a damp room is worth a professional look even if it falls under the line. A mold inspection can establish how far the growth actually reaches.
Why must the assessor and the remediator be different companies?
Under section 468.8419 of the Florida Statutes, an assessor may not remediate a structure it assessed in the previous 12 months, and a remediator may not assess one it remediated in that period. The rule stops the person who tests from also selling the cleanup.
Consider what a combined arrangement would mean. A company that finds mold and then sells the removal has a financial reason to find more of it, and a homeowner has no easy way to know whether the findings were shaped by the job that followed. Separating the two roles removes that tie. The 12-month window runs in both directions, so a remediator cannot come back and certify the work it just completed.
When comparing quotes, ask each company whether it is testing, removing, or both, and whether it has worked on the building in the past year. A company that offers both halves on the same structure is describing the situation the statute addresses, and that is the moment to ask how the 12-month rule applies before anyone starts.
How do I look up a mold license before hiring anyone?
Ask the company for its DBPR license number, then look that number up on the state's license search. Confirm that the license type matches the work, assessor for testing and remediator for removal.
A license number is not printed on this site, and no company should be trusted on the strength of its website alone. Ask for the number directly, by phone or in writing, and run the lookup on the state's own site. Check that the name on the license matches the business you are dealing with, not just a similar name.
Ask whether the person on site holds the license for the work being done, not only whether the company holds one. An assessment license does not cover removal, and a remediation license does not cover testing. If the answer is vague or the number will not be given, treat that as information about the company.
What does mold risk look like in a Lakeland summer?
Lakeland's rainy season and humidity set the timing. The EPA recommends keeping indoor humidity below 60 percent, ideally between 30 and 50 percent, and drying wet areas within 24 to 48 hours where possible.
The National Weather Service describes the west central Florida rainy season as running roughly from late May to early October, and notes that 55 to 70 percent of the annual rainfall typically falls from June through September. Wet walls, humid rooms and a closed-up house in August create the conditions mold needs to grow. Those months are the ones when a leak or a storm is most likely to leave materials damp for longer than they should be.
The same EPA guidance treats 24 to 48 hours as the window for drying wet areas. That is a prevention target rather than a guarantee, and it is why moisture readings matter. A structural drying crew measures wet materials so that drying can be confirmed rather than assumed, and the readings can be shared with a homeowner or an insurer.
What can a mold license promise, and what can't it?
Mold can trigger allergy and asthma symptoms in some people. A license tells you who is qualified to perform a role, not what the final outcome of the job will be.
The reason to take mold seriously is health, and the EPA describes mold as something that can trigger allergy and asthma symptoms in some people. That is why visible growth and damp materials should be dealt with promptly, and why it matters whether the company testing the problem is separate from the company removing it.
A license does not guarantee a mold-free home, and no company can honestly offer that. What it establishes is that the person working on the job passed the state examination for that role. The 12-month separation tells you the testing was not sold by the same company doing the cleanup. Coverage questions are decided by your insurer under your own policy, not by a license.
What should a Lakeland homeowner do before signing anything?
Get the license number for each role, confirm which role each company is performing, and check the 12-month separation. Keep your own photos and notes whatever you decide.
Start by asking for the DBPR license number for each role on the job, then ask what the company will do: test, remove, or both. If the answer is both on the same structure, ask how the 12-month rule applies to that building and get the scope in writing before any work begins. A mold remediation scope should name the area, the method and the clearance readings the company will use.
Keep your own record. Take photos before anything is moved, note where you saw staining or smelled dampness, and save any written assessment. Stop the water if you can do it safely. Call your insurer early, because coverage is decided under your policy. Phones are answered 24/7, and a crew is dispatched as fast as one is available.
Frequently asked questions
Do I need a licensed mold remediator for a small patch?
Florida's licensing rules apply to mold areas above about 10 square feet, so a small, contained patch sits under that line. The figure comes from Rule 61-31.102 and is worded as an approximation rather than a fixed cutoff. A smaller patch can still be worth an assessment, because visible growth often hides more behind a wall. Read the rule text or ask the department if the exact wording matters for your situation.
Is a contractor the same as a mold license holder?
Not necessarily. Rebuilding after water damage generally needs a Florida-licensed contractor, while mold assessor and mold remediator are separate DBPR license types. A company that holds one license does not automatically hold the other. Ask each company which license it holds for the specific work it is quoting. Any contractor can be looked up on the state's license search.
Can the same company test and clean up my mold?
Not if it assessed the structure in the previous 12 months and is now remediating it. Under section 468.8419 of the Florida Statutes, an assessor may not remediate a structure it assessed in that period, and a remediator may not assess one it remediated. Plan the sequence before anyone starts, and ask whether the testing can come from a separate company. That keeps the findings independent of the cleanup price.
How do I verify a mold license in Florida?
Ask the company for its DBPR license number, which it should give you on request. Look the number up on the DBPR website and check that the name and license type match the business and the work being offered. If the number is refused or the name does not match, keep looking. This site does not print license numbers, so the lookup has to be done with the company's number.
Does a mold license help with my insurance claim?
A license says who is qualified to do the mold work, while your insurer decides what your policy covers. Take photos before anything is moved, keep any written assessment, and ask your agent how your policy treats mold and water damage. A crew can document the damage for your claim, but coverage is decided by your insurer under your own policy.
Why does humidity matter for mold after a storm?
Mold needs moisture to grow, and the EPA recommends keeping indoor humidity below 60 percent. Lakeland's rainy season runs from about late May into early October, and most of the year's rain falls June through September. Materials that stay wet for days give mold the time it needs. Drying within 24 to 48 hours where possible is a prevention target, not a guarantee.
