Our Duct Repair & Sealing Services in Fort Myers
Duct Sealing
Air leaks in Fort Myers ductwork don’t just waste money - they pull humid attic air into your system, accelerating mold growth and making your AC work harder year-round. We seal with professional-grade mastic and reinforced mesh, not duct tape (which fails in months here). A typical duct sealing job in Fort Myers runs $280-$450 for a single system, with larger homes or multi-zone setups reaching $550-$750. Every sealed joint is camera-verified before we leave.
Flex Duct Repair
Flex duct is the default in most Fort Myers homes built after 1980, and it’s where we find the most post-Ian problems. Original flex runs in rebuilt homes often contain 2022 flood debris, crushed sections from contractor traffic, or torn insulation that’s now sweating condensation into your ceiling. Flex duct repair in Fort Myers typically costs $180-$340 per run, with full replacement of damaged sections running $220-$400. We use insulated, vapor-barrier flex rated for our humidity load - not the cheap stuff that delaminates in two seasons.
Metal Duct Repair
Older east-side Fort Myers homes in 33901 and 33905 still have original galvanized metal ductwork, and after forty-plus years of condensate drip, those seam leaks are structural. Tape won’t hold. We cut out corroded sections, fabricate replacement pieces, and seal with two-coat mastic application. Metal duct repair in Fort Myers runs $320-$580 depending on accessibility and extent of corrosion. These jobs take longer, but they’re the only repair that lasts.
Duct Insulation
Uninsulated or degraded duct insulation in Fort Myers is an efficiency killer. Attic temperatures here regularly exceed 130°F in summer, and every degree of lost cooling is money you’re paying FPL for twice. We wrap with formaldehyde-free fiberglass insulation or closed-cell foam where space allows, sealed with vapor-barrier jacket. Duct insulation in Fort Myers typically runs $450-$850 for a complete single-system wrap, with partial repairs starting at $280. Snowbirds especially benefit - proper insulation reduces the humidity cycling that causes mold during summer vacancy.

Trusted Brands We Service in Fort Myers
We stock parts and specify equipment from Abatement Technologies, Rotobrush, and Aprilaire - the same brands serious HVAC contractors in Fort Myers use in commercial installations. That means no waiting on special orders for standard repairs. Our Rotobrush agitation systems handle the heavy debris loads we see in post-Ian remediation work, while Aprilaire filtration components integrate with sealed duct systems for homeowners who want to address air quality at the source. We don’t sell brands we wouldn’t install in our own homes.
Common Duct Repair & Sealing Problems We See in Fort Myers Homes
- Post-Ian flex duct contamination: In south Fort Myers neighborhoods around 33908, we regularly find Ian-era contractors reinstalled original flex duct runs without cleaning them. Brand-new drywall, new flooring, new kitchen - and the ducts are still circulating 2022 flood debris and mold spore loads. The homeowner smells it within weeks. We repair or replace the affected runs and seal the system properly.
- Snowbird mold at supply registers: Fort Myers’s seasonal residents leave homes vacant from May through October with thermostats set to 85°F. Interior humidity spikes, condenses inside flex ducts, and November returns bring visible mold at registers. Repairs must include full microbial remediation and sealing - not just wiping the grilles.
- Fiberglass duct board delamination: McGregor corridor and older east-side homes in 33901 and 33905 still have original fiberglass duct board systems. The subtropical humidity degrades the binder, the board delaminates, and patching with mastic alone fails within months as the substrate continues to break down. We replace with metal or insulated flex, then seal.
- Corroded metal seam leaks: Decades of condensate drip in original metal ducts has eaten through seams in homes throughout 33901 and 33905. Quick tape patches fail immediately in our humidity. We remove corroded sections, fabricate replacements, and apply full mastic-sealing with insulation wrap.

FAQs - Duct Repair & Sealing in Fort Myers
Yes, and we see this constantly in rebuilt south Fort Myers homes. Contractors often replaced drywall, flooring, and even HVAC equipment but left original flex duct runs untouched - so your new system is pushing air through ducts still carrying 2022 flood debris and mold spore loads. We camera-inspect the full duct run, identify contaminated sections, and repair or replace as needed. Call (844) 685-6342 for a free inspection - estimates are free.
Yes, if you’ve had any prior leaks, mold issues, or if your ducts are poorly insulated. Sealed, properly insulated ductwork reduces the humidity cycling that causes condensation inside flex runs during summer vacancy. We also recommend a pre-departure inspection for any home where the thermostat will sit at 85°F for months. Our $89 Seasonal Tune-Up includes a basic duct assessment. Call (844) 685-6342 to schedule before you head north.
Repair addresses specific leaks, crushed sections, or seam failures while preserving the overall duct layout. Replacement becomes necessary when the substrate itself is failing - fiberglass duct board that’s delaminating, or flex duct with degraded insulation that’s shedding particles into the airstream. In 1970s McGregor corridor and east-side 33901 homes, we often find original fiberglass board that’s beyond repair; we replace with metal or insulated flex and seal the new system properly. We’ll show you the camera footage and give an honest recommendation - no scare tactics. Call (844) 685-6342 for an exact assessment.
Yes, typically 15-30% in homes with significant leakage, according to Department of Energy studies we’ve seen validated in local field conditions. Sealed ducts don’t just stop cooled air from escaping - they stop your system from pulling 130°F attic air and excess humidity into the supply stream. That means your AC runs less, dehumidifies better, and lasts longer. Most Fort Myers homeowners see the difference on their first FPL bill. Call (844) 685-6342 for a free estimate.
Properly applied, water-based mastic sealant lasts 15-20 years even in our humidity. The key is surface preparation - we clean and prime the substrate, apply reinforced mesh at joints, and build to the manufacturer’s specified thickness. Cheap tape or thin-skimped mastic fails in months. We use Guardsman professional-grade mastic, applied by technicians who know the difference. And we back it with our 90-Day Done Right Promise: if it fails, we return at no charge. Call (844) 685-6342.
We recently sealed a flex duct system in a 1970s McGregor corridor slab home whose owner had gut-rehabbed after Ian but skipped duct work. Using Rotobrush agitation and Guardsman mastic, we repaired delaminated fiberglass board at the plenum and sealed all take-offs - restoring airflow and stopping the drywall dust recirculation that had been fogging the home for months. Camera-verified, done in one visit, backed in writing for 90 days.
