Mold Remediation Cost - Written Scope Before Any Wall Comes Out

How Much Does Mold Remediation Cost in Jacksonville?

Mold remediation in Jacksonville, FL typically costs between $1,200 and $4,500 for most residential jobs in 2026, with an average around $2,300. Small contained outbreaks in bathrooms or closets can run as low as $500, while whole-attic or crawl space jobs with structural drying can exceed $8,000. These figures reflect what Jacksonville homeowners actually pay when a licensed crew removes the mold, addresses the moisture source, and verifies the fix with post-remediation testing.

This guide breaks down real Jacksonville pricing: line items, square footage costs, what drives prices up or down, and what a written estimate should include. If you’re dealing with active mold growth right now and want a price in writing before anyone touches a wall, call Keegan Restoration Jacksonville at (904) 664-5108 for a free estimate.

Key Takeaways

• Typical range: $1,200 to $4,500 for most Jacksonville homes; $500 to $1,200 for small, contained jobs.
• Average cost: Around $2,300 across Duval County and the beaches corridor.
• Per square foot: $10 to $30 per square foot of affected area, depending on contamination level and surface type.
• Attic or crawl space: $2,500 to $8,000 when structural wood, insulation, and full containment are involved.
• Biggest cost drivers: square footage, mold type (Stachybotrys vs. common mildew), HVAC contamination, and whether drywall or insulation must come out.
• Biggest mistake: paying for “spray and paint” treatments that don’t remove the moisture source. Mold returns, and the job costs twice.

Mold Remediation Cost Breakdown (2026)

Here’s what Jacksonville homeowners can expect to pay, line by line, based on jobs Keegan has estimated across the metro area this year:

Line Item	Typical Jacksonville Cost	Notes
Inspection & mold assessment	$150 to $400	Often credited toward remediation if you hire the same company.
Mold testing (air or surface sampling)	$200 to $600	Third-party lab analysis. Essential before and after for insurance claims.
Small contained remediation (bathroom, closet, under-sink)	$500 to $1,200	Under 30 sq ft. Usually done in half a day.
Single room (bedroom, utility room, garage wall)	$1,200 to $2,800	Includes containment, HEPA air scrubbing, material removal, antimicrobial treatment.
Multiple rooms or hallway runs	$3,000 to $5,500	Common after AC condensate leaks or slow plumbing leaks inside walls.
Attic remediation (full)	$2,500 to $7,500	Jacksonville’s humidity makes attic mold extremely common. Includes insulation removal and decking treatment or replacement.
Crawl space mold & encapsulation prep	$3,000 to $8,000	Includes vapor barrier work, joist treatment, and often dehumidifier installation.
HVAC system cleaning (if contaminated)	$600 to $1,800	Duct cleaning plus coil and pan treatment. Critical in Jacksonville’s air-conditioned homes.
Drywall removal & replacement	$2.50 to $5.00 per sq ft	Removal included in remediation; replacement is a repair cost.
Post-remediation verification testing	$250 to $500	Confirms spore counts are back to normal outdoor levels.
Moisture source repair (plumbing, flashing, grading)	Varies widely	The remediation only works if the source is fixed. Ask for this to be priced separately, in writing.

These are the numbers we write on estimates every week in Jacksonville. The range exists because no two mold jobs are the same: a bathroom ceiling stain behind a leaking supply line is a half-day containment job; Stachybotrys ran through an attic from a roof leak that went unnoticed for eight months is a multi-day structural project.

What Affects Mold Remediation Pricing in Jacksonville

Six factors move the price more than anything else. None of them are a mystery, and a straight answer on each one should be in your written estimate.

• Square footage of affected area. Remediation is priced by the square foot of contamination, not the square footage of your house. A 3,000 sq ft home with 40 sq ft of mold in one bathroom costs less than a 1,500 sq ft home with mold across three bedroom ceilings. The equipment, containment, and labor scale with the affected surface.
• Type of surface. Porous materials (drywall, insulation, carpet pad, ceiling tile) get removed and replaced. Non-porous surfaces (tile, concrete, metal, hardwoods) can often be cleaned and treated in place. Jacksonville homes built before the 1990s sometimes have plaster walls instead of drywall; plaster is harder to match and slightly more expensive to work with when sections must come out.
• Containment requirements. Any job over 10 square feet of mold calls for a negative air containment with HEPA air scrubbers running the entire time. That’s equipment time, filter changes, poly sheeting, and labor setup. It is non-negotiable when mold has moved into wall cavities or HVAC ducting, and it adds $400 to $900 to most jobs.
• HVAC involvement. Florida homes run AC ten months a year, and mold spores travel through ductwork faster than anywhere else. If the air handler, evaporator coil, or ducts show contamination, the scope of work expands significantly. Duct cleaning plus coil treatment typically adds $600 to $1,800, but skipping it means the remediation fails and the guarantee can’t be honored.
• Mold species and spore load. Chaetomium and Stachybotrys (the “black mold” you hear about) require stricter containment protocols and more aggressive material removal. Healthy adults with no respiratory issues sometimes tolerate common Cladosporium exposure; people with asthma, immune conditions, or infant children in the home cannot. Professional judgment on this is exactly what you pay a remediation contractor for.
• Post-remediation verification and rebuild. The cheapest quote in Jacksonville is almost always just “kill and clean.” A complete scope includes moisture-source repair, material removal, treatment, verification testing, and repair of what was removed. Make every contractor put each phase in writing so you can compare line by line, not total to total.

Jacksonville-Specific Factors That Drive Mold Problems

This city grows mold faster than almost anywhere in the continental United States, and the reasons are physical, not hypothetical. Jacksonville averages 50 to 55 inches of rain per year, sits at sea level with a shallow water table across much of Duval County, and runs dew points above 70°F from May through October. That means the indoor relative humidity in a closed, unventilated home can climb past 65 percent within days of an AC failure. At 60 percent relative humidity and above, dormant mold spores activate and colonize porous surfaces within 24 to 48 hours.

What that looks like in real neighborhoods: homes in Riverside and Avondale, with their 1920s to 1940s pier-and-beam construction, consistently show crawl space mold from groundwater vapor wicking into floor joists. San Marco and Ortega homes with flat or low-slope roofs develop attic mold after autumn leaf buildup traps water against the decking. Mandarin and Julington Creek subdivisions see mold inside HVAC closets and air handlers where the condensate drain line backs up in the wet season. Arlington and the Southside, dense with 1960s through 1980s slab-on-grade homes, get mold behind baseboards where slab moisture wicks up through cracks and behind walls where original copper supply lines sweat against drywall.

None of these are hypothetical. We write estimates for these exact failures dozens of times a year. The moisture source matters more than the mold itself: fix the water, and the mold doesn’t come back. Skip the source, and you’re paying twice.

Cost Per Square Foot: What Jacksonville Actually Pays

Contractors quote mold remediation one of two ways: a line-item fixed price for the defined scope, or a per-square-foot rate for the affected area. Here’s what the per-square-foot rates look like in this market:

• $10 to $15 per sq ft: Surface mold on non-porous materials (tile, concrete, metal). Clean, treat, no removal needed.
• $15 to $22 per sq ft: Mold requiring drywall or insulation removal in one or two rooms. Standard containment.
• $22 to $30 per sq ft: Heavy contamination, structural wood, HVAC involvement, or Stachybotrys requiring full PPE and extended containment.
• Above $30 per sq ft: Crawl space and attic jobs with structural drying, sealants, and rebuild coordination.

So a 75 sq ft section of water-damaged drywall with mold in a Mandrin laundry room runs about $1,100 to $1,650 for removal, containment, and treatment. A 250 sq ft attic decking job with insulation removal and HEPA scrubbing runs $5,500 to $7,500. Same company, same crew, same equipment. The difference is the scope.

Is It Cheaper to Repair or Replace Mold-Damaged Materials?

For porous materials, replacement is almost always cheaper than attempted restoration. Drywall that holds mold cannot be cleaned to a standard that stands up to post-testing. Once drywall gets wet and stays wet, the paper facing feeds mold and the gypsum core crumbles when it dries. A 4×8 sheet of drywall costs about $18 at any Jacksonville supplier. The labor to hang, tape, and finish that sheet costs far less than the labor hours of scrubbing, sanding, and re-treating a compromised board.

The same logic applies to insulation. Fiberglass batt insulation that’s been wet and moldy goes in a bag. Nothing about it is salvageable to an IICRC standard. Blown-in attic insulation is the same story. We remove it, treat the decking and framing, and the homeowner blows in fresh insulation at the repair stage.

Non-porous materials are different. Tile, concrete, metal framing, and hard-surface piping can be cleaned, wire-brushed if needed, and treated with an EPA-registered antimicrobial. That saves real money on slab homes where the subfloor is concrete and the only porous materials are drywall and trim.

Where homeowners lose money is paying a contractor to “treat” drywall that should have been cut out. If the estimate says “antimicrobial application” on water-damaged drywall with visible mold, ask why the board isn’t coming out. The answer should mention scope, air quality, and post-testing. If it doesn’t, get a second estimate.

How Much Does Mold Removal Cost in Jacksonville by Room?

Most people don’t think in square feet. They think in rooms. Here’s the honest room-by-room breakdown for this market:

• Bathroom (ceiling or wall around tub surround): $500 to $1,500. Usually from a slow supply line leak behind the wall or inadequate vent fan exhaust. Small containment, open the wall, treat, dry, close up.
• Kitchen (under-sink cabinet, behind dishwasher, or ceiling below upstairs bathroom): $700 to $2,200. Cabinet interiors often get cut out, which means matching cabinet work during repair.
• Bedroom (ceiling or wall from roof leak or AC overflow): $1,200 to $3,000. Depends on whether the leak was active long enough to take insulation with it.
• Garage (walls and door trim): $800 to $2,500. Jacksonville garages are a major mold zone because cars bring in rainwater and humidity sits high in unconditioned space.
• Closet (wall or ceiling): $600 to $1,800. Often discovered late because closets are dark and stuffed. Good news: small area. Bad news: often means the leak is inside a shared wall.
• Whole attic: $2,500 to $7,500. Insulation removal, decking treatment, sometimes rafter replacement, and ventilation correction.
• Whole crawl space: $3,000 to $8,000+. Includes joist treatment, vapor barrier, and in many Jacksonville homes, a dehumidifier.

Each of these assumes the moisture source gets fixed at the same time. If the roof leak or pipe leak isn’t addressed, no remediation price is worth paying.

The Real Jacksonville Mold Problem: Humidity and AC

Jacksonville doesn’t just have mold from leaks. This city has mold from the air itself. When the AC goes down in August, the indoor dew point climbs to match the outdoor dew point, which sits in the mid-70s most of the summer. Within 48 hours, drywall ceilings, closet interiors, and the back side of baseboards start growing Cladosporium even with no water event at all.

Homes built after the 2000s are tighter than older homes, which is good for energy efficiency and bad for trapped humidity. A modern Jacksonville house with the AC off on a summer weekend becomes a mold incubator, especially if the homeowner is away. Snowbirds who close up a Jacksonville house from May through October come home to mold growth almost every season unless the AC is maintained and the home is monitored.

The fix is not a chemical. The fix is condition control: run the AC, keep indoor relative humidity below 55 percent, install and maintain bath fans that vent to the exterior, and correct any grading or gutter issues that put groundwater against the slab or foundation. Then remediate what’s already growing. That order matters.

Can You Do Mold Remediation Yourself in Jacksonville?

For a patch under 10 square feet on a non-porous surface like tile or glass, a homeowner can clean it with soap and water and fix the source. That’s the EPA’s own guidance. For anything bigger, anything inside a wall cavity, anything in the HVAC system, or anything with a musty odor you can’t locate, the work belongs to a trained professional. Here’s why this is not a warning we make lightly:

Mold spores are measured in microns. A single disturbed square foot of active mold can release hundreds of thousands of spores into the air. Without negative air containment, those spores move through the house and colonize every other room with a moisture source. What starts as a $1,200 bathroom job becomes a $6,000 whole-house job because the homeowner scrubbed drywall that should have been removed.

Plus, the health risk is real. The people most likely to react to mold exposure are the same people who shouldn’t be anywhere near a DIY remediation: infants, elderly family members, people with asthma or immune conditions, and anyone with chronic respiratory issues. A professional crew runs HEPA air scrubbers, sets up plastic containment barriers, uses full PPE with respirators, and disposes of contaminated material in sealed bags per Florida solid waste rules. If you have Stachybotrys or Chaetomium in a Jacksonville attic or wall cavity, the DIY window has honestly closed.

Call a professional. Get a written price. Compare it to what a weekend of your own time, equipment rental, and potential cross-contamination would cost. Most homeowners in Jacksonville land on the professional estimate being the cheaper option once they see the scope on paper.

How Keegan Restoration Jacksonville Prices Mold Remediation

Here’s exactly how our estimates work, because the pricing structure itself is part of the reputation we’ve built since joining the Garrison Partners family in 2005.

Every mold job starts with a written scope of loss. That document lists the affected square footage, the materials requiring removal versus treatment, the containment setup, the equipment hours, the antimicrobials and sealants to be used, and the post-remediation verification testing. The price goes in writing before any tool comes off the truck. It does not move at the door.

Our technicians arrive background-checked and in uniform. They run professional-grade equipment from Dri-Eaz, Phoenix, XPOWER, B-Air, and Injectidry, operated in compliance with IICRC, RIA, and IFA standards. We document every job with photos, moisture readings, and material logs formatted to support your insurance claim. A live person answers our phone 24 hours a day, 7 days a week, including nights, weekends, and holidays. When water is actively damaging your home, you talk to a human being, not a phone tree.

And every repair carries the 365-Day Done Right Promise in writing. If the work fails within one year, we return and make it right at no charge. That’s The Garrison Standard, and Shane Pruitt runs every Jacksonville job to it.

The estimate is free. Call (904) 664-5108 and we’ll schedule a walkthrough, put numbers on paper, and let you decide from there.

Mold Remediation vs. Mold Removal: What You’re Actually Paying For

The industry uses “remediation” instead of “removal” for a reason. You cannot remove every mold spore from a home, because mold spores exist in outdoor air everywhere in Florida. What remediation does is bring the indoor spore count back in line with normal outdoor levels and remove the active colonization. “Removal” as a marketing word promises something that isn’t physically possible; a contractor using the word “removal” isn’t necessarily doing anything wrong, but a contractor who explains the difference is giving you the honest version.

Remediation includes: source control (fixing the water), isolation (containment), air filtration (HEPA), demolition of unsalvageable porous materials, surface cleaning and antimicrobial treatment on salvageable materials, drying to a standard verified by moisture meters, and clearance testing. The full scaffold of that process is what $1,200 to $4,500 buys on a typical Jacksonville job.

What it doesn’t include is reconstruction. Repair work (drywall replacement, painting, trim, cabinet replacement, insulation, flooring) is a separate scope and a separate line item on any honest estimate. Some restoration companies handle both remediation and rebuild. Keegan does. We’ll line-item both phases so you and your insurance adjuster can see exactly where the money goes.

Insurance Coverage for Mold Remediation in Jacksonville

Florida homeowners insurance policies typically cover mold remediation only when the mold is secondary to a covered peril: a sudden pipe burst, storm water intrusion, an AC overflow caused by a covered failure. Slow leaks, neglect, and humidity-driven mold are usually excluded. And most standard policies carry a mold sub-limit, often $10,000 or less, regardless of the size of the loss.

What that means in practice: if a supply line bursts behind the wall in your Southside townhome and mold is discovered during water mitigation, the remediation is likely covered up to the sub-limit. If your Riverside bungalow has had a slow leak under the kitchen sink since before you bought it and mold has spread through the cabinet base, that’s a maintenance issue in the eyes of most adjusters. Reading your policy before you file is the smartest first step.

What helps with any claim is documentation. A job file with photos from before remediation, moisture readings, containment and equipment logs, and third-party lab results gives your adjuster something to approve. That’s exactly the file we build on every Keegan job. It’s part of running to The Garrison Standard: write the price, do it by the book, and give the homeowner a record that holds up.

How to Save on Mold Remediation in Jacksonville Without Cutting Corners

There’s a right way and a wrong way to save money on mold work. The wrong way is hiring the lowest bid and hoping. The right way is shrinking the scope before it grows. Here’s how:

• Act fast. Mold doubles its affected area every 48 to 72 hours in Jacksonville’s warm, humid air. A $900 problem today is a $3,500 problem in two weeks. The cheapest mold job is the one you catch early.
• Fix the source first. If the leak isn’t stopped, the remediation doesn’t last. Get a plumber or roofer out the same week you spot the mold. Every day the source runs is another day of spread.
• Get the estimate in writing before work starts. A written line-item scope lets you compare contractors on the same scope instead of comparing a $1,100 vague quote against a $1,900 detailed one. The detailed one is usually the honest one.
• Ask what’s salvageable. Non-porous surfaces don’t need replacement. A good contractor will already be telling you this. If everything on the estimate says “remove and replace,” question it.
• Combine the remediation with the rebuild. Using one contractor for both phases saves mobilization costs and coordination time. The seamless handoff from remediation to repair also protects the warranty.
• Check your insurance before paying out of pocket. A burst pipe that led to mold is very different from a slow leak that rusted for a year. Know your sub-limit and have documentation ready.

The biggest honest savings is the free estimate. Call us before you make any decision, even if you end up working with someone else. A written scope with real numbers gives you a benchmark against every other bid, and that knowledge alone is worth the phone call.

What Should a Mold Remediation Estimate Include in Jacksonville?

If you get an estimate that says “mold remediation: $2,400” and nothing else, throw it away. A real estimate is a scope of work. Here’s what to look for:

1. Affected area description: specific rooms, surfaces, and square footage. Not “upstairs area.”
2. Containment plan: where poly barriers go, what kind of negative air is used, and for how long.
3. Material removal list: how much drywall, insulation, carpet, or trim comes out, measured in square feet or linear feet.
4. Equipment list: HEPA air scrubbers, dehumidifiers, air movers, and for crawl spaces and attics, desiccant dehumidifiers from brands like Dri-Eaz or Phoenix.
5. Antimicrobial and treatment products: EPA-registered products, stated by name, with application method.
6. Drying plan: target moisture content on wood and drywall, and the meters used to verify it.
7. Post-remediation verification: who does the clearance testing, what lab processes the samples, and what makes the pass/fail line.
8. Repair scope: either in the same estimate or referenced as a separate document with its own price.
9. Warranty: what’s guaranteed, for how long, and what happens if the work fails. Ours is the 365-Day Done Right Promise, in writing, for a full year.
10. Total price: in writing, before work starts, with any exclusions stated.

That ten-point structure is The Garrison Standard on paper. If an estimate doesn’t at least address most of those points, you don’t have enough information to compare bids.

FAQs – Mold Remediation Cost

How much does mold remediation cost in Jacksonville, FL?

Most Jacksonville homeowners pay between $1,200 and $4,500 for mold remediation in 2026, with small contained jobs starting around $500 and large attic or crawl space projects reaching $8,000 or more. The exact number depends on square footage, surface type, and whether HVAC ducting is contaminated. Call (904) 664-5108 for a free written estimate with real numbers for your specific situation.

Is mold remediation covered by insurance in Florida?

Mold remediation is typically covered only when the mold is secondary to a sudden covered peril like a pipe burst or storm water intrusion, and most Florida policies carry a mold sub-limit around $10,000. Slow leaks and humidity-driven mold are usually excluded. Documentation is your best leverage: photos, moisture readings, and lab results formatted for your adjuster.

How much does a mold inspection cost in Jacksonville?

A mold inspection & testing assessment typically runs $150 to $400 in the Jacksonville area, and many companies credit that fee toward the remediation if you hire them. Lab testing for air or surface samples adds $200 to $600 depending on the number of samples. Keegan Restoration Jacksonville offers free estimates, which include a visual assessment and scope review at no charge.

Can mold come back after remediation?

Mold will always return if the moisture source isn’t fixed, which is why any honest remediation scope includes source control. If the plumbing leak, roof penetration, or humidity condition is corrected and the affected materials are properly removed and treated, the mold does not return. At Keegan, every job is backed by the 365-Day Done Right Promise: if it fails within one year, we return and make it right in writing, at no charge. That’s our guarantee, and it applies to every mold job in Jacksonville.

How long does mold remediation take in a Jacksonville home?

Most single-room jobs in Jacksonville are done in one to two days. A typical 100 sq ft bathroom or bedroom scope is a one-day remediation with containment setup in the morning and post-testing the following day after air scrubbers run overnight. Whole-attic or crawl space projects run three to five days including structural drying and clearance testing. Your written estimate should include a timeline.

Is it cheaper to do mold remediation myself?

For a patch under 10 square feet on a hard surface, yes, a homeowner can clean it with soap and water and fix the source. For anything larger, DIY usually costs more in the long run because disturbed spores spread through the home and the problem becomes bigger than it started. Containment, HEPA air scrubbing, proper PPE, and verified clearance testing are not weekend project items, especially in Jacksonville’s humidity. The free estimate is the cheapest way to find out what your actual scope is.
