Mold Assessor vs. Mold Remediator in Florida

General information, not legal, medical, engineering or insurance advice.

Florida licenses two kinds of mold professional: mold assessors, who work out where mold is and why it's there, andmold remediators, who remove it. The two roles are kept separate by law. Here's what each license covers under Part XVI of chapter 468, Florida Statutes, and when you need each one. Rules change, so treat the statutes linked below as the authority.

What Florida law says each one does

Section 468.8411, Florida Statutes, defines the terms:¹

The same section says remediation work that needs a construction license under chapter 489 must be done by someone licensed under that chapter or must comply with it.¹ In practice, rebuilding walls, floors or other parts of the structure after mold removal may need a licensed contractor.

Licenses are issued to individuals. A company may offer mold services through its licensed employees, but the statute says nothing in it allows a corporation to hold a mold assessment or mold remediation license.²

The 12-month rule: why one person shouldn't do both

Section 468.8419 lists things licensees may not do. Two rules keep assessment and remediation independent:³

• A mold assessor may not perform or offer to perform mold remediation on a structure where the assessor or the assessor's company provided a mold assessment within the last 12 months (s. 468.8419(1)(d)).
• A mold remediator may not perform or offer to perform a mold assessment on a structure where the remediator or the remediator's company provided mold remediation within the last 12 months (s. 468.8419(2)(d)).

Neither rule applies to a certified contractor classified as a Division I contractor under section 489.105(3), which covers general, building and residential contractors. The statute lets DBPR adopt rules requiring that contract to tell the homeowner they have the right to request competitive bids.^3,4

The same section also bars:³

• Referral payments either way between assessors and remediators (or their companies).
• An assessor inspecting, for a fee, a property in which the assessor or their company has a financial or transfer interest.
• An assessment where the assessment itself, or its fee, depends on the conclusions it reaches.
• Using titles such as “licensed mold assessor” or “mold remediator” without complying with the licensing law.

When you need an assessor

• You smell mold or see signs of water damage but can't find the source.
• The affected area looks larger than about 10 square feet, or may extend inside walls, ceilings or the HVAC system.
• You want a written scope (often called a remediation protocol) that remediators can quote against, so quotes are comparable.
• You want an independent check after remediation, before walls are closed up.

Testing isn't always needed. EPA says that “in most cases, if visible mold growth is present, sampling is unnecessary,” and CDC does not recommend routine mold testing.^6,7 A good assessment is about finding moisture and defining what must be removed, not only sampling. Ask what any sampling is meant to answer.

When you need a remediator

You need a remediator to remove or treat mold growth of more than 10 square feet, since that's the work Florida's definition covers. For smaller areas, EPA says you can usually handle the job yourself if the moldy area is less than about 10 square feet, and suggests consulting its remediation guidance where there has been a lot of water damage or mold covers more than 10 square feet.⁵ EPA also advises calling a professional when the damage came from sewage or other contaminated water.⁵

Florida's exemptions let a residential property owner assess or remediate mold on their own property without a license.⁸ If you have health concerns, EPA suggests consulting a health professional before starting cleanup.⁵

A typical order of work

1. Stop the water: fix the leak, dry the area, and deal with humidity. EPA's rule of thumb is that the key to mold control is moisture control.⁶
2. Hire a licensed mold assessor for an inspection and written report, where the problem is large or hidden.
3. Get 2–3 written quotes from licensed mold remediators, ideally against the same written scope.
4. Remediation, with containment to keep dust and spores out of clean areas.
5. A post-remediation check, often by the original assessor, before rebuilding.
6. Rebuild with a licensed contractor where the work requires one.

Check the license before you hire

Look up the person's name or license number on the DBPR license searchand confirm the license type matches the job. Our guide on verifying a Florida mold license walks through it.
