Our Duct Repair & Sealing Services in Bonita Springs
Duct Sealing
Leaky ducts waste 20-30% of conditioned air in a typical Bonita Springs home, and that’s money you’re sending straight into your attic. We seal supply and return plenums, trunk lines, and branch connections using professional-grade mastic sealant and metal-backed tape rated for Florida’s heat and humidity. In Bonita Springs’s tile-roof homes built during the 1990s and 2000s, we regularly find separations at duct-to-boot connections where settling has pulled the joint apart. Our Duct Repair & Sealing in Bonita Springs process includes a pressure test to verify we’ve stopped the leaks before we leave.
Flex Duct Repair
Bonita Springs’s housing stock is heavy with flex-duct systems installed from the mid-1980s through the mid-2000s, particularly in gated communities like Bonita Bay, Pelican Landing, and Palmira. These ducts run through attic spaces that hit 140°F in July, and the combination of UV degradation through attic vents and persistent moisture causes the inner liner to collapse or delaminate. We replace collapsed runs with new insulated flex duct, properly supported to prevent sagging, and we always verify airflow at the register before we close up. A typical flex duct repair in Bonita Springs runs $280-$480 per run.
Metal Duct Repair
Older metal ductwork in Bonita Springs, found in some of the area’s original 1970s and 1980s construction, suffers from rust at seams and loose joints where the original sealant has dried out. We reseal metal systems with mastic compound and install mechanical fasteners where needed. For metal ducts that have taken water intrusion - a persistent issue in low-lying Bonita Springs neighborhoods near the Imperial River after Hurricane Ian’s 2022 surge - we assess whether repair or section replacement is the sounder long-term fix.
Duct Insulation
When Bonita Springs ducts run through unconditioned attic space, missing or degraded insulation causes condensation on the exterior of the duct during our humid summer months. That moisture drips onto ceiling drywall and breeds mold. We install fresh fiberglass duct wrap with vapor barrier, sealed at all seams, to maintain the temperature differential that prevents condensation. This is especially important for seasonal homes where the AC cycles less frequently and attic humidity has more time to attack the system.
Mastic Sealant
We use fiber-reinforced mastic sealant on every duct repair we perform in Bonita Springs, not duct tape. Tape dries out and fails in attic heat; mastic remains flexible and airtight for the life of the system. We paint it onto every joint, seam, and penetration with a brush or sprayer depending on access, then verify with visual inspection. In Pelican Landing condominiums and other multi-story buildings where access is tight, mastic allows us to seal connections that mechanical fasteners simply cannot reach.
Air Leak Repair
Air leaks in Bonita Springs ductwork often pull unfiltered attic air into the system, carrying fiberglass particles, dust, and in our humid climate, mold spores. We locate leaks with smoke testing and pressure diagnostics, then seal them systematically. The result is cleaner air, more even temperatures room-to-room, and an AC system that doesn’t have to run overtime to compensate for lost air.

Common Duct Repair & Sealing Problems We See in Bonita Springs Homes
- Flex-duct liner collapse in hot attics. The 20-30-year-old flex duct common in Bonita Springs’s mid-1980s to mid-2000s construction degrades from the inside out in attic heat. The liner tears away from the wire helix, restricting airflow or blocking it entirely. We replace the run and improve support to prevent recurrence.
- Mold colonization in snowbird-seasonal ducts. When Bonita Springs seasonal residents set thermostats to 80°F or shut AC off entirely from May through October, duct interiors hit humidity levels that sustain active mold growth within weeks. The musty odor hits when owners return in November. We clean, treat, and seal the system to break the cycle.
- Post-Hurricane Ian flood damage in low-lying communities. The 2022 storm surge drove contaminated water into duct systems near the Imperial River and estuary corridors, including parts of Bonita Bay. Even where homeowners dried visible water, residual contamination in duct interiors creates ongoing air quality problems. We assess and remediate these systems with camera verification.
- Separation at duct-to-boot connections in tile-roof homes. Bonita Springs’s prevalent low-slope tile-roof construction often pairs with duct boots that weren’t properly secured during original installation. Settling over 20+ years pulls the connection apart, leaking conditioned air into the attic and pulling attic air into living spaces.

FAQs - Duct Repair & Sealing in Bonita Springs
The smell comes from mold that grew inside your ducts during the May-October humid season while your AC was off or set high. Bonita Springs’s position between the Gulf and the estuaries keeps humidity higher than inland Lee County, and dormant ducts hit moisture levels that sustain active mold colonization within weeks. We clean - including our Dryer Vent Cleaning in Bonita Springs if needed - and seal the system to eliminate the source, not just mask the odor. Call (844) 685-6342 before you head north next spring and we can set a maintenance schedule that prevents the problem.
Yes, particularly in low-lying communities near the Imperial River where storm surge reached duct systems that were never properly opened and remediated. We still find contaminated material in these systems, and the damage isn’t always visible from the registers. Our camera inspection shows what’s actually inside. If your Bonita Springs home took water in 2022 and you haven’t had ducts inspected since, it’s worth doing.
We use fiber-reinforced mastic sealant on every Bonita Springs job, including condominiums in Pelican Landing and Palmira where access is limited. Mastic remains flexible in attic heat and creates a permanent seal that tape cannot match. We paint it onto every joint by hand and verify coverage before we close up. It’s the standard serious HVAC contractors specify, and it’s what we use.
Collapsed flex duct needs replacement, not repair. The inner liner has separated from the wire helix, and patching it creates turbulence and future failure points. We remove the damaged run, install new insulated flex duct with proper support straps to prevent sagging, and seal all connections with mastic. Most Palmira flex duct replacements we perform run $280-$480 per run and are completed in one visit.
Running fine doesn’t mean running efficiently. Leaky ducts force your AC to work harder, shortening equipment life and raising bills. In Bonita Springs’s seasonal homes, the problem compounds because leaks also pull humid attic air into the system, accelerating mold risk during your absence. Sealing is preventive maintenance that pays for itself in efficiency and avoids the November surprise. We offer $89 our HVAC Cleaning in Bonita Springs tune-ups that include a basic leak check. Call (844) 685-6342 to schedule before you close up for summer.
