60 verified companies · checked against FL DBPR

Typical Florida mold remediation: $1,100–$4,200 · market range, varies by affected area

On the same property Florida keeps those two roles with different companies for 12 months (§468.8419), so an independent assessment usually comes first — the narrow exception is a Division I contractor certified under §489.105(3).

Hiring a mold company in St. Johns County

Do I need a licensed mold company in St. Johns County?
Yes for most jobs. Florida requires a DBPR mold license for any assessment or remediation covering more than 10 square feet (§468.8411). 60 companies serving St. Johns County hold a license we have checked against the state registry, and each listing shows the date it was checked.
Can one company both test and remove mold in St. Johns County?
Not on the same property within 12 months. Florida separates the mold assessor (MRSA), who inspects and writes the protocol, from the remediator (MRSR), who does the work — §468.8419. The narrow exception is a Division I contractor certified under §489.105(3). St. Johns County has 48 independent assessors and 43 remediators.
What does mold remediation cost in St. Johns County?
Most Florida mold remediation jobs fall between $1,100 and $4,200. That is the statewide range — price moves with the size of the affected area, whether drying equipment is needed, and how much material has to be removed, not with the county line.
Who can do a mold inspection in St. Johns County?
A licensed mold assessor. What most people book as a mold inspection is what Florida calls a mold assessment — §468.8411(3) defines it as physical sampling plus an evaluation of the building's history and inspection to establish the origin, location, and extent of mold over 10 square feet. St. Johns County has 48 independent assessors (MRSA). A home inspector may flag visible mold within the scope of the license they already hold under §468.841, but that exemption ends the moment anyone uses a title implying mold licensure — Florida's mold program licenses assessors and remediators, not a “mold specialist” — so ask for the MRSA number.
Who does mold removal in St. Johns County?
A licensed mold remediator (MRSR). Mold removal is the everyday name for what Florida calls mold remediation — §468.8411(5) defines that as the removal, cleaning, sanitizing, demolition or other treatment of mold or mold-contaminated matter over 10 square feet. Florida licenses no removal trade of its own, so the MRSR credential stands behind either phrase, and mold testing is likewise the everyday name for the assessment side (MRSA). St. Johns County has 43 licensed remediators and 48 assessors in this directory. Read a “100% mold removal” promise as a sales claim rather than a standard — remediation returns a building to normal background spore levels, which is what post-remediation clearance testing measures.

The split between the two licenses is the part most people get caught by — what a mold assessor does that a remediator cannot walks through where the line falls, and what a Florida mold inspection includes covers the sampling, moisture mapping and written report an assessment should produce.
