Our Duct Repair & Sealing Services in Fort Myers Shores
Flex Duct Repair
The ranch homes that dominate Fort Myers Shores were built with early-generation flex duct that was never designed to last 40 or 50 years. We’ve replaced collapsed flex runs in homes along Orange River Boulevard where the original polyethylene liner had deteriorated into flakes, and in attics near Joel Boulevard where flood sediment from Ian had packed the duct so thoroughly that no air could move. Our Duct Repair & Sealing team cuts out damaged sections and installs new flex or transitions to metal trunk lines where the application calls for it. A typical flex duct repair or partial replacement in Fort Myers Shores runs $350-$900.
Duct Sealing
Sealing is often the most cost-effective improvement for Fort Myers Shores homes with intact but leaky metal ductwork. We use professional-grade mastic sealant applied to every joint, seam, and penetration point, not the tape that dries and falls off in attic heat. In the humid, near-tropical climate here, proper sealing prevents conditioned air from escaping into unconditioned spaces and stops hot, moist attic air from being pulled into the system. Most sealing jobs in Fort Myers Shores range from $250-$650 for accessible systems.
Metal Duct Repair
Some Fort Myers Shores homes, particularly those built in the late 1950s and early 1960s, have galvanized steel trunk lines that have corroded at seams or separated at joints. We repair these with metal patches, mechanical fasteners, and mastic sealant, replacing sections only when corrosion has compromised structural integrity. Metal duct repair in Fort Myers Shores typically costs $400-$1,200 depending on accessibility and extent of damage.
Duct Insulation Replacement
The fiberglass insulation wrapped around Fort Myers Shores ductwork degrades rapidly in unconditioned attics where summer temperatures exceed 140°F. Once insulation loses its R-value, condensation forms on cold duct surfaces during cooling cycles, and that moisture feeds mold growth even without any flood history. We remove deteriorated insulation and install new, properly sealed insulation barriers. Insulation replacement jobs in Fort Myers Shores generally run $500-$1,400.
Mastic Sealant Application
For flood-prone homes in the 33905 ZIP code, mastic is our preferred sealant because it remains flexible after curing and creates a monolithic barrier that tape cannot match. We apply it to all new connections and repairs, and we can re-seal entire existing systems as a standalone service. Mastic sealing is included in our standard duct sealing pricing and is particularly effective at preventing future intrusion at joint points.

Most repairs are completed in one visit because our technicians arrive with what they need.
Common Duct Repair & Sealing Problems We See in Fort Myers Shores Homes
- Original flex ducts from the 1960s-80s collapse under flood sediment and mold biogrowth. The lightweight plastic liners in these early systems weren’t built to support the weight of river silt and accumulated microbial growth, and we regularly find completely collapsed runs in Fort Myers Shores attics that have been forcing the HVAC system to overwork for years.
- Flood silt left in ducts after cosmetic repairs acts as a moisture reservoir. Standard post-Ian renovation work addressed drywall, flooring, and cosmetics, but duct interiors were almost never opened. That dried silt rehydrates during humid periods and feeds continuous mold colonization that circulates through living spaces.
- Unconditioned attic heat degrades aging duct insulation, causing condensation. Even homes that never flooded face this problem. When insulation compresses or falls away, the temperature differential between 55°F conditioned air and 140°F attic air creates persistent condensation that accelerates mold and rust.
- Biogrowth accumulates faster here than in seasonal climates. Fort Myers Shores’s near-tropical humidity and year-round air conditioning operation means ducts never get a dry season to self-clear. We find thick biofilm layers in systems that would stay clean for decades in drier, cooler climates.

At a 1963 ranch on Orange River Boulevard, we found the original flex duct collapsed from Ian’s flood pressure, with dried silt coating the inner liners and mold growing on every seam. We cut out the contaminated sections, installed new Rotobrush-cleaned metal trunk lines, and sealed all joints with mastic to prevent future flood intrusion. The homeowner had lived with reduced airflow and musty odors for two years, assuming the problem was the aging AC unit itself. It wasn’t. The ducts were the problem, and the fix cost less than half what she’d been quoted for unnecessary equipment replacement.

FAQs - Duct Repair & Sealing in Fort Myers Shores
Post-storm renovation contracts almost never included duct interior cleaning or inspection, so floodwater that pushed through supply lines left dried river sediment inside even in cosmetically restored homes. That silt rehydrates during humid periods and continues circulating particulates through living spaces. If you smell mustiness when your system runs or see dust patterns near registers, call (844) 685-6342 for a camera inspection - estimates are free.
Partial repair is possible when damage is limited to accessible sections, but flood-contaminated flex duct with silt infiltration and mold growth typically requires full replacement because the porous inner liner cannot be adequately cleaned. We make this determination with camera inspection, not guesswork. Our technicians will show you exactly what they see and recommend repair or replacement based on condition, not commission.
Water-based mastic sealant outperforms tape in humid attic environments because it remains flexible after curing and creates a continuous, gap-free barrier that won’t dry and separate. We apply mastic to every joint, seam, and penetration on new and repaired ductwork in Fort Myers Shores homes. It’s the standard we use on our own work because it holds up.
We remove all contaminated materials rather than covering them, seal joints to prevent future moisture intrusion, and can install UV sanitizing or upgraded filtration as part of the repair scope. Proper insulation replacement eliminates condensation surfaces. No prevention method is absolute in a subtropical floodplain, but our approach addresses the root causes rather than treating symptoms. Call (844) 685-6342 to discuss what makes sense for your home.
Yes. Typical unsealed duct systems in Fort Myers Shores’s 1960s-1980s ranch homes lose 20-30% of conditioned air to attic leaks, forcing the AC to run longer and work harder. Sealing those leaks reduces runtime, lowers humidity more effectively, and often pays for itself in reduced energy bills within one or two cooling seasons. We measure before-and-after airflow on every sealing job so you see the improvement.
