In short: mold removal in Miami Beach typically costs $10–$25 per square foot of affected area, or $15–$30 where walls must be opened or the AC system is involved. Most single-room jobs fall between $1,500 and $6,000. An independent assessment adds about $450–$900. All of these are estimates.
Price summary
| Job | Estimate | Notes |
|---|---|---|
| Small isolated area (about 10 sq ft or less) | $500–$1,500 | One spot, one surface |
| One room, moderate growth | $1,500–$6,000 | The most common job |
| Several rooms or system involvement | $6,000–$15,000 | Usually a hidden leak |
| Whole unit or home, severe | $10,000–$30,000+ | Gutting and full containment |
| Per square foot, standard | $10–$25 | Containment, removal, HEPA, disposal |
| Per square foot, complex | $15–$30 | Wall cavities, HVAC, hard materials |
Prices by where the mold is
| Job | Estimate | Notes |
|---|---|---|
| Bathroom (surface growth) | $500–$2,000 | More if the shower pan leaked into the wall |
| AC closet, air handler and ducts | $3,000–$10,000 | Coordinated with an HVAC contractor |
| Water-damaged wall after a leak | $1,500–$6,000 | Per room, including cut-out |
Testing and clearance
| Job | Estimate | Notes |
|---|---|---|
| Independent mold assessment | $450–$900 | Paid to the assessor |
| Lab samples | $50–$120 each | Only where they answer a question |
| Post-remediation clearance | $300–$500 | Before walls are closed |
Testing is optional for many visible, known-cause jobs. The inspection and testing page explains when it is worth the fee.
Drying after a leak
If the water is recent, drying is usually cheaper than remediation: about $1,500–$3,500 for one room of clean water, and $3,500–$8,000 for two or three. The water damage page has the full table, including gray and black water.
About these numbers: they come from published South Florida cost guides reviewed in 2026, not from your property. The figure that matters is the written price after we measure, and it does not change unless the scope does.
What moves the price on Miami Beach
- How much material is affected. Price follows square feet of contaminated drywall, cabinetry and flooring, not the size of the unit.
- What it is growing on. Painted concrete block cleans in place; drywall, insulation and particleboard usually come out and go in the dumpster.
- The AC system. If spores have reached the air handler and ducts, the HVAC side becomes its own scope with its own cost.
- Building logistics. Condo towers mean a certificate of insurance, booked service elevators, limited work hours and paid parking for the crew. A ground-floor house has none of that.
- Containment size. One sealed closet is quick to set up; a full unit under negative air needs more machines for more days.
- Rebuild. Remediation ends with clean, dry, open walls. New drywall, paint, tile and cabinets are a separate contractor and a separate price.
Insurance and mold sublimits
Many Florida homeowner and HO-6 policies cap mold at a sublimit, commonly $5,000 to $10,000, and only when the mold follows a covered sudden water event like a burst supply line. Gradual leaks and long-term humidity are usually excluded. Our completion report records the source, the affected area and the readings, which is what an adjuster asks for either way.
Why Miami Beach mold quotes disagree
Put three remediation quotes side by side and the totals can differ by thousands for the same closet. Usually they describe different jobs. One includes the independent assessment and clearance; one leaves you to arrange both. One prices a sealed containment with a negative air machine; one sprays and wipes. One hauls the debris down the service elevator; one assumes the building dumpster. Ask each company to list the containment, the materials removed, the HEPA and antimicrobial steps, disposal, and whether clearance is included. When those match, the prices tend to as well.
Per square foot, as a comparison aid
Square-foot pricing is useful for sense-checking a quote, not for predicting one. A 40 square foot patch at $25 a foot is $1,000 before setup, and every job carries a minimum for containment and equipment. Larger areas usually come in toward the lower end of the range.
Cost questions
What is the average cost of mold removal in Miami Beach?
A single room with moderate growth usually lands between $1,500 and $6,000, as an estimate. Small isolated patches cost less; anything involving the AC system or several rooms costs more.
Does homeowners insurance pay for mold removal?
Sometimes, when the mold follows a sudden covered water loss, and usually only up to a mold sublimit that is often $5,000 to $10,000 on Florida policies. Mold from long-term humidity or a slow leak is commonly excluded. Read your policy's mold section or ask your agent.
Why is the assessment a separate bill?
Because Florida keeps assessors and remediators independent. The assessor works for you, not for us, so their fee is paid to them directly.
Is a cheaper quote always worse?
Not always, but check what it leaves out: containment, negative air, the assessment, clearance, disposal and rebuilding are the usual gaps. Compare the scope line by line before comparing totals.
