Florida mold remediation cost calculator

How does this mold remediation cost calculator work?

The calculator starts from the published Florida range for the kind of job you pick — bathroom, attic, HVAC, whole house — then scales it by how much area is affected: a single patch under about 10 sq ft costs roughly 0.5× a room-scale job, and a widespread one over 500 sq ft about 3.5×. Your metro multiplier applies last (Miami 1.12, Jacksonville 0.92).

1. 1. Pick where the mold is. Bathroom, attic, crawlspace, HVAC, after a flood, or whole house. Each maps to its own 25th–75th percentile band in the published cost corpus, last refreshed 2026-06-03 — not to one flat per-square-foot rate.
2. 2. Set how large the affected area is. Under ~10 sq ft, ~10–100 sq ft, ~100–500 sq ft, or over ~500 sq ft. Size scales that band (0.5×, 1×, 2×, 3.5×). Small jobs never fall to zero, because mobilizing a crew has a floor cost.
3. 3. Choose your Florida metro. Each priced metro carries its own multiplier — Miami 1.12, Tampa 0.97, Orlando 0.95, Jacksonville 0.92 — applied last, with every tier rounded to the nearest $25. The result is a market range to check bids against, not a quote.

A range is only useful if the company bidding it is allowed to do the work: §468.8411(3) and (5), Fla. Stat., define mold assessment and remediation as work on more than 10 square feet, so anything above that line needs a DBPR-licensed assessor or remediator. Check a license number against the state registry before you hire.

What actually drives the price

• Affected square footage. The single biggest lever. A one-spot patch and a multi-room job are different bills entirely.
• Porous materials involved. Drywall, insulation, carpet, and wood usually have to be removed and replaced — not just cleaned — which adds material and labor.
• Whether HVAC is involved. Once mold reaches the air handler or ducts, it can spread house-wide. Cleaning or replacing duct components raises the cost sharply.
• The moisture source. A good job fixes the leak or humidity problem that caused the mold. Skip that and it comes back — so a fair quote includes the fix, not just the cleanup.
• Containment and clearance. Negative-pressure containment, HEPA scrubbing, and an independent post-job clearance test cost more up front but are what separate a real remediation from a wipe-down.

Typical Florida cost ranges by area

Statewide ranges for the job itself, before metro adjustment. The estimator above applies your metro multiplier (for example Miami runs higher, Jacksonville lower). A multiplier moves the range; the scope of the job sets the price, and whoever bids it should hold the matching DBPR license — each of the Jacksonville mold remediators we list carries the date we last checked its license against the state registry. Figures last refreshed 2026-06-03.

Does mold remediation cost more in some Florida metros than others?

Yes — about 24% between the top and the bottom of the state. The same room-scale remediation runs roughly $2,575 in Miami and about $2,075 in Tallahassee and Pensacola. The metro multiplier only shifts the band — the scope of the job still sets the price.

A typical single-area job (~10–100 sq ft), priced the way the calculator above prices it: the statewide band × that metro's multiplier, rounded to $25. Multipliers come from our published cost corpus, last refreshed 2026-06-03. Each metro links to the companies we list there, carrying the date we last checked the licence against the DBPR registry.

Florida mold-cost FAQ

The questions homeowners ask most about what mold work should cost in Florida — answered with the same published ranges shown above.

How much does mold remediation cost in Florida?

A professional mold remediation in Florida typically runs about $1,100 to $4,200, with a statewide median near $2,300 — roughly $11 to $26 per square foot. Those are statewide figures; metro pricing shifts them, with Miami running about 12% above and Jacksonville about 8% below the state baseline. Bathroom-scale jobs cost less; HVAC or whole-house contamination costs far more.

How much is a mold inspection in Florida?

A Florida mold inspection typically runs about $250 to $700, with a median near $450 — a separate bill from the remediation this calculator prices. Florida keeps the two roles apart: a licensed mold assessor (MRSA) inspects and writes the protocol, and a different licensed remediator does the removal work (§468.8419). See what an independent Florida mold inspection costs.

How much does it cost to remove black mold in Florida?

Removing visibly dark mold in Florida typically runs about $1,500 to $5,800, with a median near $3,000. Price is driven by how much material is affected and whether porous drywall, insulation, or framing must be removed — not by the mold's color. A dark stain in one bathroom corner is a smaller job than a few square feet of dark growth across studs after a slow leak.

Why is mold in the HVAC or whole house so much more expensive?

Once mold reaches the air handler or ducts it can move through the whole house, so HVAC-involved jobs in Florida typically run about $2,000 to $9,500 and whole-house contamination about $9,000 to $32,000 (median near $17,500). The cost is the scale of removal and replacement, plus cleaning or replacing duct components, not a premium for any one type of mold.

Is a very cheap mold quote a red flag in Florida?

It can be. A quote far below the statewide $1,100 floor for anything beyond a small patch often means the scope skips what makes remediation work: negative-pressure containment, HEPA scrubbing, fixing the moisture source, and an independent post-job clearance test. In Florida, the assessor who writes the protocol and the remediator who does the work should be different licensed parties — a single price for "test and fix it" is worth questioning.
