Four things change your quote.
No single number fits every home. Here's what a licensed remediator is actually pricing when they walk your property.
Area size
A 6-square-foot bathroom patch and a 60-square-foot wall cavity are not the same job. Size roughly doubles the scope at each step up.
What's behind the drywall
Visible growth is the cheap part. Once mold is inside walls or under floors, demolition and rebuild costs stack on top of remediation.
HVAC involvement
If your AC or ducts are affected, every system that shares air has to be isolated and cleaned. This is the single biggest price driver.
Local market
Miami and Austin remediators charge more than San Antonio and Savannah. Demand, humidity, and licensing bar all factor in.
Estimates are only useful if the quote comes from someone real.
The range above assumes a licensed, insured remediator. Unlicensed quotes are often lower — but they can void your homeowner's insurance and leave you liable for mistakes.
Licensed
State-verified daily against the FL, TX, and GA license databases. Not self-reported.
Insured
Current certificate of insurance on file. Expiration tracked. Your property is covered if something goes wrong.
Rated
4.0★ or higher with at least 5 real reviews. No anonymous padding.
The assessor can't also do the job. By law.
Florida separates assessment from remediation
Under Florida law, one licensed company can't both assess AND remediate mold on the same property. The assessor writes the scope. A different, licensed remediator does the work. This protects you from a conflict of interest — the person diagnosing the problem shouldn't be the one paid to “fix” it.
The Assessor
Inspects, tests, writes the protocol. Paid for diagnosis only. Cannot bid on the remediation.
The Remediator
Executes the protocol written by the assessor. Licensed separately. Can't inspect their own work.
If someone in Florida offers to do both — walk away. In Texas and Georgia, rules differ, but the same conflict-of-interest principle still protects you.
Why your state matters.
Florida, Texas, and Georgia all price differently — and regulate differently. Here's what gets baked into your range, by state.
High humidity. Strict licensing.
FL requires separate licenses for mold assessors and remediators — one company legally cannot do both jobs on the same property. Coastal humidity also drives more frequent HVAC involvement.
Miami ×1.30 · Orlando ×1.10Big houses. Flood-driven jobs.
TX remediation often follows storm or plumbing damage, so jobs run larger. Licensing is through TDLR (MRS/MRC) and is verified here daily. Austin pricing runs noticeably higher than San Antonio.
Austin ×1.20 · Houston ×1.15Expanding market. Fewer rules.
GA doesn't require a specific mold license, so verification here means checking general contractor licenses plus IICRC/IAQA certification. Atlanta trends with Tampa on pricing; Savannah runs at the national average.
