Every job starts with a free inspection and a written scope. The standard air duct mold cleaning Fort Pierce FL package covers the full supply and return system, the air handler, and the evaporator coil. Add-ons like crawl space encapsulation or duct replacement are quoted separately and only if you need them. Here is what you get when you book with us.
We run a boroscope inspection camera through every accessible duct run and use a thermal imaging camera to check for hidden moisture. You get a written report with photos and a clear recommendation. This step takes 60 to 90 minutes and is free if you proceed with the cleaning.
Technicians use HEPA vacuums and rotary brushes to remove mold, dust, and debris from every duct wall. We work from the farthest register back to the air handler so nothing gets pushed deeper into the system. A typical home takes three to five hours for this phase.
We apply EPA-registered antimicrobial spray to every interior duct surface, the evaporator coil, and the drain pan. Products include Concrobium, Benefect, and ShockWave depending on the surface and the level of contamination. This leaves a residual that inhibits regrowth for months.
Throughout the job, an air scrubber and negative air machine keep your living space under negative pressure so spores cannot escape into the rooms. We run the scrubber for at least 30 minutes after cleaning to clear any remaining airborne particles before we remove containment.
We walk you through the finished work, show you before-and-after photos, and provide a written summary of what we found and what we did. You also get a 12-month warranty on the ductwork. If you need clearance testing, we can schedule that as a follow-up.

Air Duct Mold Cleaning Fort Pierce FL is a mechanical remediation process that removes mold growth, spores, and settled debris from the interior surfaces of your supply and return ductwork, then treats those surfaces so regrowth does not return with the next humid week. We start with a boroscope inspection camera to see inside the runs, then seal every register with plastic sheeting and duct tape to build negative pressure. A HEPA vacuum and air scrubber pull loose spores out while a fogger applies Concrobium or Benefect to the duct walls. The job is not finished until moisture readings are back under 15 percent.
Fort Pierce sits in one of the most humid pockets of the Treasure Coast, and that humidity is exactly what black mold needs. When your AC runs eight months a year, condensation forms on cold duct surfaces, dust collects, and within a few weeks you have visible growth. Homeowners near the Marina District and along Hutchinson Island often call us after a roof leak or a storm surge pushed water into the attic. If you have been searching for air duct mold cleanup near me Fort Pierce, the answer is a crew that understands coastal moisture, not a generic cleaning company.

We arrive with a boroscope inspection camera and thermal imaging camera to look inside every accessible duct run. We check for visible growth, water stains, and elevated moisture readings. You get a written report with photos and a clear recommendation within 60 to 90 minutes. If the ducts are clean, we tell you that and you pay nothing for the inspection.
Before any cleaning starts, we seal every supply and return register with plastic sheeting and duct tape. A negative air machine pulls the work area under negative pressure so spores cannot drift into your living space. This step takes about 30 minutes and is the single most important part of keeping your family safe during the job.
Technicians run a HEPA vacuum through every duct run, then follow with rotary brushes and compressed air whips to knock loose debris off the duct walls. The vacuum captures everything as it comes free. A typical 1,800-square-foot Fort Pierce home takes three to five hours for this phase depending on how many runs and how much contamination we find.
Once the ducts are clean and dry, we apply an EPA-registered antimicrobial spray such as Concrobium or Benefect to every interior surface. This is not a cover-up; it is a residual treatment that inhibits mold growth for months. We also treat the evaporator coil and drain pan, which are common hidden growth points in Florida HVAC systems.
We take final moisture readings and run the air scrubber for at least 30 minutes to clear any remaining airborne spores. You get a walkthrough with before-and-after photos, a written summary of what we found and what we did, and a 12-month warranty on the ductwork. If you need post-remediation verification and clearance testing, we can arrange that too.

Lets us see inside every duct run without cutting into walls. We document what we find with photos so you can see the condition of your system before and after cleaning.
Reveals temperature differences that indicate hidden moisture behind drywall or in the attic. This is how we find the water source feeding mold growth without tearing your home apart.
Captures mold spores and debris down to 0.3 microns. We run the scrubber throughout the job and for at least 30 minutes after cleaning to clear airborne particles.
Keeps the work area under negative pressure so spores cannot drift into your living space during cleaning. This is a standard part of every job we do.
Applies Concrobium, Benefect, or ShockWave to every interior duct surface. These EPA-registered products leave a residual that inhibits mold regrowth for months.
Confirms when materials are dry enough to finish the job. We do not close out a duct cleaning until moisture readings are back under 15 percent.
We follow the IICRC Applied Microbial Remediation Technician standard for containment, removal, and verification. This is the industry benchmark that insurance adjusters and clearance testers recognize. It is why our documentation holds up.
Every register is sealed with plastic sheeting and duct tape, and a negative air machine pulls the work area under pressure. This keeps spores out of your living space during the entire job. It is the single most important safety step.
After mechanical cleaning, we apply EPA-registered antimicrobials to every surface. Unlike a one-time spray, these products leave a residual that continues to inhibit growth. We treat the coil and drain pan too, not just the ducts.
Cleaning without fixing the moisture source is a temporary fix. We use thermal imaging and moisture meters to find the source, then correct it with dehumidification, encapsulation vapor barrier, or leak repair before we finish.

We inspect the ductwork with a boroscope inspection camera and check the air handler, evaporator coil, and drain pan. Hidden growth in those areas is the most common cause of unexplained musty odors in Fort Pierce homes. You get a clear answer and a written scope. If the ducts are clean, we tell you and you pay nothing for the inspection.
We set up containment, extract any standing water, and run Dri-Eaz or Phoenix Restoration drying equipment until moisture readings are normal. Then we perform full ductwork mold removal Fort Pierce and treat the system. The system is dry, clean, and treated. We provide documentation you can submit to your insurance carrier.
We perform air and surface sampling, clean and treat the ductwork, and arrange post-remediation verification and clearance testing. Lab results come back in about 48 hours. You get a clearance report that satisfies lenders, buyers, and real estate agents so the transaction can move forward.
We inspect the full system, clean the ducts with HEPA vacuums and air scrubbers, and install HEPA filters. We also check for hidden mold behind drywall and in the crawl space. Indoor air quality improves noticeably within 24 to 48 hours. Most customers report fewer symptoms within the first week.
Fort Pierce is one of the most humid cities on Florida's Treasure Coast, with average relative humidity above 70 percent for most of the year. That is well above the 50 percent threshold where mold thrives, which is why ductwork mold removal Fort Pierce is such a common call. Homes near the water, from the Marina District to Hutchinson Island, deal with salt air and storm-driven moisture on top of everyday humidity. Older homes in Downtown and the Peacock Arts District often have original ductwork with deteriorated insulation and leaks that let attic air into the system. Newer construction in areas like Waterstone and Bent Creek is tighter, but that means less natural ventilation and more reliance on the AC, which can actually concentrate moisture if the system is not balanced. We size dehumidifiers and encapsulation vapor barrier systems for this specific climate, and we know which neighborhoods flood during summer storms. If you need same-day air duct mold cleaning in Fort Pierce, call before noon and we can usually be there that afternoon.
Coastal humidity and older housing stock make this one of our most frequent service areas. Duct systems here often have corroded boots and visible growth at the registers.
Storm surge and salt air accelerate corrosion in HVAC equipment. We see more coil and drain pan mold here than anywhere else in the city.
Many homes here have long duct runs through hot attics. Attic temperatures above 130 degrees in summer bake dust onto duct walls, giving mold a place to settle.
Renovated older buildings often have a mix of original and replacement ductwork. We inspect both because the older runs are usually the contamination source.
Mold can colonize a damp duct surface in as little as 48 hours. We recommend dehumidification and annual duct inspections for most Fort Pierce homes.
Heat bakes dust and organic matter onto duct walls, creating a food source for mold. Ducts running through attics need cleaning more often than those in conditioned space.
Water intrusion from storms is a leading cause of sudden mold growth in ductwork. We respond same-day to storm-related calls across St. Lucie County.
Deteriorated duct insulation traps moisture and sheds particles into the air stream. We often recommend replacing compromised runs as part of the remediation.
A 1,600-square-foot home near the Marina District had a musty smell for six months. The homeowner had cleaned the vents and changed filters with no improvement. Our boroscope found heavy black mold growth in the return duct and on the evaporator coil, with moisture readings above 20 percent.
We sealed the system, HEPA-vacuumed all runs, treated the coil and ducts with Concrobium, and installed a whole-home dehumidifier. Post-job moisture readings were under 12 percent. The homeowner reported the smell was gone within 24 hours and has not returned.
Maintenance: Change HEPA filters every 60 days and keep indoor humidity below 50 percent. We schedule a follow-up inspection at the 12-month mark to confirm the ducts are still clean.
A condo on Hutchinson Island South took on water during a summer storm. The AC smelled earthy and the tenant reported headaches. Inspection found mold in the air handler pan and two supply runs, plus elevated moisture in the ceiling drywall above the ducts.
We extracted standing water, ran Dri-Eaz and Phoenix Restoration drying equipment for three days, then performed full ductwork mold removal Fort Pierce. All moisture readings returned to normal, and clearance testing confirmed spore counts were back to outdoor levels.
Maintenance: We installed a vapor barrier in the utility closet and recommended the condo association schedule annual duct inspections before hurricane season each June.
Two children in a Lakewood Park home had year-round allergy symptoms that got worse indoors. The HVAC system had never been cleaned in 12 years. Inspection found mold growth in four of six duct runs and a clogged evaporator coil restricting airflow by an estimated 20 percent.
We cleaned all six runs with HEPA vacuums and rotary brushes, treated the system with Benefect, and replaced the coil filter. Airflow improved measurably and the family reported fewer symptoms within the first week. The system has stayed clean through two humid seasons.
Maintenance: The family now runs a dehumidifier set to 48 percent and changes filters every 60 days. We do a quick boroscope check each spring at no charge.
Most ductwork mold problems in Fort Pierce trace back to one of a handful of root causes. Identifying the cause is what separates a permanent fix from a repeat call. Here are the issues we see most often and how we handle them.
The smell means active mold growth somewhere in the system, and every cycle spreads spores through your living space. Allergy symptoms, headaches, and respiratory irritation often follow. We locate the growth with a boroscope inspection camera, seal the system, and perform full ductwork mold removal Fort Pierce. We also treat the evaporator coil and drain pan, which are the most common odor sources in Florida HVAC systems.
Black mold around registers usually means contamination has reached the duct boots and nearby drywall. Ignoring it lets the growth spread deeper into the duct runs and into the wall cavity. We remove and treat the affected duct boots, cut out and replace contaminated drywall with mold-resistant drywall, and clean the full duct run. We also check the attic or crawl space above for the moisture source feeding the growth.
When indoor humidity stays above 60 percent, cold duct surfaces sweat and mold colonizes within weeks. This is the single most common cause of recurring duct mold in Fort Pierce. We install whole-home or crawl space dehumidifiers, seal duct leaks, and where needed install an encapsulation vapor barrier. Bringing humidity below 50 percent stops condensation and removes the condition mold needs to grow.
If a prior cleaning did not address the moisture source, mold comes back within a few months. Homeowners end up paying twice for the same problem. We start with moisture mapping using a thermal imaging camera and moisture meter to find the source. Then we fix the source, clean the ducts, and apply antimicrobial spray. Our 12-month warranty covers regrowth in treated runs.
$450 - $1,800 for most residential jobs; commercial and multi-zone systems quoted separately
Typical 2026 pricing for air duct mold cleaning Fort Pierce FL ranges from $450 to $1,800 for most residential jobs. The low end covers a single-system home with light contamination in a few runs. The high end covers larger homes, multiple HVAC zones, or heavy growth that requires coil treatment and duct replacement. We give you a written price after the free inspection, and that number does not change unless you ask us to add work. No hourly billing, no surprise fees for containment or antimicrobial products.
A full duct cleaning costs a fraction of what you would pay to replace an HVAC system damaged by mold or to treat a family member with chronic respiratory issues. We fix the moisture source so the result lasts, and every job carries a 12-month warranty.
A 1,200-square-foot home with six runs takes less time and product than a 3,000-square-foot home with 15 runs. Most of the price difference comes down to labor hours and how many registers we have to seal and clean.
Light surface growth cleans up quickly. Heavy growth that has penetrated duct insulation or spread to the air handler requires more aggressive mechanical cleaning and longer antimicrobial treatment. We show you photos so you can see what we are pricing.
Ducts in a conditioned attic or crawl space are easier to reach than those buried under insulation or behind finished walls. Difficult access adds labor time, which is reflected in the quote. We tell you upfront if access will affect the price.
If the inspection finds a moisture source that needs fixing, like a crawl space that needs encapsulation vapor barrier or a leak that needs repair, that work is quoted separately. We never bundle it in without your approval.
Flex duct that is torn, collapsed, or saturated with mold cannot be cleaned and must be replaced. Replacement runs typically add $150 to $400 per run depending on length and attic access. We only recommend it when cleaning will not solve the problem.

Our technicians hold IICRC Water Restoration Technician (WRT) and Applied Microbial Remediation Technician (AMRT) certifications, and we operate under a Florida Mold-Related Services License (MRSA). We also maintain EPA Lead-Safe Certification and OSHA 10 training for every crew member. That matters in Fort Pierce because older homes near Downtown and the Peacock Arts District often have lead paint and asbestos-containing materials that require careful handling. We have worked in St. Lucie County homes built from the 1920s through new construction, and we know how each era of ductwork behaves.

We had a musty smell in the house for months and could not figure out where it was coming from. CoveGuard found black mold in the return duct and the air handler pan. They sealed everything off, cleaned it out, and treated the whole system. The smell was gone the next day. They also showed me photos of the before and after, which I appreciated.
I manage six rental units near Downtown and two of them had tenants complaining about allergies. CoveGuard inspected all six HVAC systems and found mold in three. They scheduled the work around tenant availability and finished each unit in a day. The documentation they provided made the insurance claim straightforward. I will use them again.
After the last storm, water got into our attic and we ended up with mold in the ductwork. The team came out same day, set up containment, and had the ducts cleaned and treated within two days. They also installed a vapor barrier in the crawl space to stop it from happening again. Professional crew, fair price, no surprises.
Most residential jobs run $450 to $1,800 in 2026, depending on square footage, number of duct runs, and how far the contamination has spread. A single-system home under 2,000 square feet typically lands near the lower end. Commercial buildings and homes with multiple HVAC zones cost more. We give you a written price after the inspection, and the inspection itself is free if you proceed with the work.
The three most common signs are a musty, earthy smell when the AC runs, visible dark spots around supply registers, and allergy symptoms that get worse when you are home. A boroscope inspection camera confirms it. We also use a moisture meter and thermal imaging camera to find the water source feeding the growth. If you see black mold in air ducts Fort Pierce Florida, do not run the system until it is inspected.

It depends on the cause. If mold grew because of a sudden water event like a burst pipe or storm intrusion, most Florida policies cover the remediation. If it developed slowly from high humidity or deferred maintenance, it is usually not covered. We document everything with photos and moisture readings and can work directly with your adjuster to support the claim.
