TL;DR: In Florida, mold remediation typically costs $500 to $7,000 for most residential jobs, with isolated bathroom or closet mold on the low end and HVAC or whole-room contamination on the high end. Whole-house remediation after a flood or long-term leak can run $10,000 to $30,000 or more. Most homeowners policies only cover mold removal when it stems from a sudden, covered water loss, not from humidity or a slow leak.
If you just got a mold inspection report back for your Davie home and you’re staring at a number you didn’t expect, you’re not alone. Broward County’s year-round humidity and salt air push mold growth faster than it would spread in a drier climate, and a lot of homeowners here first notice it in a guest bathroom, a laundry closet, or behind furniture pushed against an exterior wall. The price depends less on the square footage of your house and more on how much contaminated material has to come out and how the mold got there in the first place.
How much does mold remediation cost per square foot?
Most Florida remediation companies price jobs by scope and containment complexity rather than a flat per-square-foot rate, but when a per-square-foot number is quoted, it typically falls between $10 and $25 per square foot of affected material. A 10-square-foot patch of moldy drywall in a closet costs far less to fix than 10 square feet of contaminated subfloor and insulation after a slow leak, because the labor is in removal, containment, and air scrubbing, not just the surface area.
Here’s what Broward County homeowners typically pay by scenario:
| Scenario | Typical Cost Range |
|---|---|
| Mold inspection and air/surface testing | $300 - $750 |
| Small isolated area (under 10 sq ft: bathroom, closet) | $500 - $1,500 |
| Single room, moderate growth (bedroom, kitchen cabinet) | $1,500 - $4,000 |
| HVAC or duct system contamination | $2,000 - $6,000 |
| Attic or crawlspace mold | $2,500 - $7,000 |
| Whole-house remediation after flooding or a major leak | $10,000 - $30,000+ |
These ranges reflect typical industry pricing across South Florida, not a quote. Every property is different, and a licensed remediator should give you a written scope before any work starts.
What actually drives the price up or down?
The single biggest factor is how much material has to be physically removed, not how big the house is. A job that’s mostly surface cleaning and HEPA vacuuming costs a fraction of one that requires cutting out drywall, pulling insulation, and replacing subfloor.
Other factors that move the number:
- Source of the moisture. Mold from a one-time leak that’s already stopped is cheaper to remediate than mold from an ongoing humidity problem, because the underlying cause has to be fixed or the mold comes back.
- Accessibility. Attic and crawlspace work in older Davie homes near Shenandoah and Rolling Hills often costs more simply because of tight access and limited ventilation for containment.
- Materials affected. Drywall and insulation are cheap to remove and replace. Hardwood flooring, custom cabinetry, or HVAC ductwork cost more.
- Condo and HOA requirements. Communities like Pine Island Ridge often require association sign-off and specific vendor documentation before remediation work begins, which can add a step but doesn’t usually change the remediation cost itself.
- Clearance testing. A post-remediation air or surface test to confirm the space passed, often requested by insurers, lenders, or HOAs, typically adds $300 to $600.

Is mold remediation covered by insurance?
Homeowners insurance typically covers mold remediation only when the mold resulted from a sudden, accidental, covered event, like a burst supply line or a storm-driven roof leak discovered and reported quickly. Most Florida policies exclude mold caused by long-term humidity, slow leaks, or deferred maintenance, and many that do cover mold cap the payout with a mold sublimit, commonly $10,000 or less, regardless of what the actual remediation costs.
That gap is why documentation matters so much. Photos of the source damage, moisture meter readings, and a dated mitigation invoice all help establish that the mold followed a covered loss rather than a maintenance issue. Florida licenses mold remediation companies through the Department of Business and Professional Regulation (DBPR), and RestorationXpress has held that license (DBPR #1057) while serving Broward County since 2011, which matters if your insurer or HOA requires proof of a licensed vendor before approving the claim.
What does the remediation process actually involve?
A typical Florida mold remediation job runs through six steps, usually completed in 3 to 7 days depending on scope:
- Inspection and testing. Moisture mapping and, when needed, air or surface sampling to confirm mold type and extent.
- Containment setup. Poly sheeting and negative air pressure isolate the work area so spores don’t spread to the rest of the home during removal.
- HEPA air scrubbing. Industrial air scrubbers run continuously to capture airborne spores while material removal is underway.
- Removal of contaminated material. Drywall, insulation, and other porous materials that can’t be fully cleaned are cut out and bagged for disposal, following EPA guidance for safe mold cleanup.
- Antimicrobial treatment and drying. Remaining surfaces are treated and the space is dried to prevent regrowth, often referencing Florida Department of Health guidance on indoor mold exposure.
- Clearance testing and rebuild. A final test confirms spore counts are back to normal before drywall, flooring, or cabinetry goes back in.
If your mold problem followed recent water damage, it’s worth reading how quickly mold grows after water damage to understand why the timeline between the leak and the call matters for both cost and coverage.
If you’re looking at a quote and not sure whether it’s reasonable for the scope described, ask for the written containment plan and the square footage of material being removed, not just a total number. Request a mold inspection and RestorationXpress will document the affected area and give you a scope in writing before anything is removed.
