Short answer
In Florida, a mold assessor evaluates conditions and, when needed, writes the remediation protocol (scope of work), while a mold remediator performs the physical cleanup. Florida's licensing framework (Ch. 468, Part XVI, F.S.) treats these as distinct roles and is built around independence between them on the same project — so the party recommending work is not the party profiting from it.
| Mold assessor (MRSA) | Mold remediator (MRSR) | |
|---|---|---|
| Core job | Investigates moisture, evaluates conditions, and writes the remediation protocol | Performs the physical containment, removal, cleaning, and drying |
| Florida license | Mold assessor license under Ch. 468, Part XVI, F.S. — number begins MRSA | Mold remediator license under the same chapter — number begins MRSR |
| Paid for | The assessment and the written report | The remediation work performed |
| Financial incentive | None tied to how much damage is found — the fee is the same either way | Revenue scales with the size of the scope |
| Both roles on one property | Generally prohibited: an assessor may not remediate a structure assessed within the prior 12 months | Generally prohibited: a remediator may not assess a structure it remediated |
| Post-remediation verification | Performs the independent clearance check after the work is done | Cannot clear its own remediation |
The independence rule is section 468.8419, Florida Statutes, and it extends to companies with a financial interest on both sides. Any MRSA or MRSR number can be verified on the Florida DBPR license portal. Sterling holds MRSA5798 and is assessment-only.
What is the difference between a mold assessor and a mold remediator?
The assessor's job is to investigate and document: find the moisture, evaluate the conditions, and, if remediation is warranted, define a clear scope of work. The remediator's job is to carry out that scope — containment, removal, cleaning, and drying.
Why does Florida separate assessment from remediation?
When one company both decides how much work is needed and gets paid to do it, there is a built-in conflict of interest. Florida's framework is designed around keeping the assessor and remediator independent on the same project, so the recommendation reflects the property's needs.
Requirements can change, so it is always worth confirming the current rules with the state licensing authority.
What does "independent" mean at Sterling?
Sterling is assessment-only. We inspect, assess, write protocols, and perform post-remediation verification — but we do not perform remediation. That means our findings are never shaped by an interest in selling cleanup, and our clearance is never a check on our own work.
