Fast, Reliable Duct Repair & Sealing Across Palmetto
Duct repair and sealing in Palmetto typically costs $180-$650 depending on whether we’re sealing metal seams with mastic or re-supporting sagging flex duct in newer subdivisions. Most Palmetto jobs are completed in a single visit, and our Duct Repair & Sealing team carries the parts to handle both the aging rigid metal systems in 34220 and the flex duct failures common in 34221. Call (844) 685-6342 for upfront pricing and a free estimate.
We’ve been driving to Palmetto since 2012, long before the Artisan Lakes and Trevesta subdivisions broke ground in 34221. We know the difference between a 1965 CBS home near the Manatee River with original galvanized ductwork and a 2010 tract house whose flex duct is already sagging in a 130-degree attic. That local knowledge means we show up with the right materials and don’t waste your time with a diagnosis that treats every Palmetto home the same.
Why Bellows Air Duct & Vent Co. Is Palmetto’s Preferred Duct Repair & Sealing Company
Palmetto homeowners have called us back for forty-two years because we answer the phone. Not an app. Not a voicemail tree. A live person, twenty-four hours a day. When your AC is blowing musty air through a cracked duct seam at ten o’clock on a Saturday, that matters.
Our technicians are background-checked, uniformed, and trained to recognize what Palmetto’s specific conditions do to ductwork. They carry camera inspection equipment on every truck, so you see the crack, the sag, or the mold pocket before we quote a dollar. The price we give over the phone is the price on the invoice. No bait coupons, no surprises at the door.
Every job carries our 90-Day Done Right Promise in writing. If the seal fails or the support loosens, we return at no charge. No paperwork to file, no argument. We’ve operated this way since Ray Castillo founded the company, and we haven’t changed.
We also offer $50 off any repair over $250, a free second opinion on any written estimate, and a permanent 5% senior and veteran discount. The $89 seasonal tune-up catches small leaks before they become expensive problems.
Our Duct Repair & Sealing Services in Palmetto
Duct Sealing with Mastic Sealant
In Palmetto’s 34220 ZIP, the original metal ducts in river-adjacent CBS homes have endured decades of thermal expansion and salt-laden humidity. Standard foil tape degrades in eighteen months here. We use professional-grade mastic sealant, applied with a brush or sprayer to form a permanent, flexible bond that fills cracks tape can’t reach. A typical mastic sealing job in Palmetto runs $180-$340 for accessible trunk lines, and we camera-verify the seal before we leave.
Flex Duct Repair
The newer 34221 subdivisions - Artisan Lakes, Trevesta, Willow Walk - were built with builder-grade flex duct that wasn’t designed for Palmetto’s attic heat. Inner liners delaminate and sag, creating low spots where condensate pools and mold colonizes. We recently repaired a sagging flex duct run in a 2012 home on Willow Walk in the 34221 ZIP where the inner liner had delaminated and pooled condensate. Standard suction couldn’t clear the mold until we re-anchored the run with mechanical supports and applied mastic sealant to restore airflow. Flex duct repair in Palmetto typically runs $280-$520 depending on linear footage and accessibility.
Metal Duct Repair
When corrosion has eaten through galvanized steel in a 34220 home, patching is temporary and often wastes money. We cut out failed sections and splice in new rigid duct or transition to properly supported flex where appropriate. Metal duct replacement sections in Palmetto run $320-$650 depending on location and whether the plenum connection is involved. We always show you the camera footage so you understand why we’re recommending replacement over sealing.
Duct Insulation and Air Leak Repair
Leaky return plenums and uninsulated duct runs in Palmetto’s older homes pull hot, humid attic air directly into your system, overworking the compressor and raising your FPL bill. We seal the leaks first, then wrap with formaldehyde-free insulation where missing or degraded. Air leak repair with insulation touch-up in Palmetto typically runs $240-$480. The payoff is lower energy use and less strain on equipment that’s already working overtime in our climate.

Trusted Brands We Service in Palmetto
We stock parts and materials from Abatement Technologies, Rotobrush, and Aprilaire - the same brands serious HVAC contractors specify for Florida’s demanding conditions. For Palmetto homeowners, that means no waiting on a parts run to Tampa while your house heats up. Our trucks carry mastic compounds rated for continuous humidity exposure, mechanical support straps that won’t fatigue in super-heated attics, and camera heads small enough to navigate the tight belly-duct configurations common in Palmetto’s manufactured housing. Most repairs are completed in one visit because we planned for what this specific market needs.
Common Duct Repair & Sealing Problems We See in Palmetto Homes
- Pinhole leaks in 34220 metal ductwork. Decades of salt air and thermal cycling corrode galvanized steel from the inside out. Standard tape lifts within a year. Mastic sealant is the only lasting fix, and we apply it after camera inspection confirms the metal is structurally sound.
- Sagging flex duct in 34221 subdivisions. Builder-grade inner liners lose tension and corrugate within 10-12 years in Palmetto’s attics. The resulting low spots trap condensate and grow mold that standard cleaning can’t reach without first re-supporting the run mechanically.
- Belly-duct moisture in manufactured homes. Common throughout both Palmetto ZIPs, these ground-level duct configurations draw moisture from underneath and develop slow leaks at connection points. Homeowners often smell mold before they feel reduced airflow. We access, dry, seal, and re-insulate with materials rated for ground-proximity installation.
- Return air leaks pulling attic heat. In both old and new Palmetto homes, gaps between the return plenum and the air handler cabinet or floor joists pressurize the attic with conditioned air and depressurize the living space. We seal with mastic and verify with smoke pencil or camera.

FAQs - Duct Repair & Sealing in Palmetto
Most 1960s metal ducts in 34220 can be sealed with mastic if the steel is still structurally sound. We camera-inspect first to check for advanced corrosion or collapse. If pinholes are scattered but the trunk is intact, mastic sealing at $180-$340 is the right call. If sections have rusted through or the plenum is disintegrating, we quote replacement and show you why. Call (844) 685-6342 for a free inspection.
Sagging flex duct in Artisan Lakes almost always needs both. The inner liner has already delaminated or lost tension, so re-supporting alone leaves the damage that caused the sag. We mechanically re-anchor the run, replace damaged liner sections, and seal with mastic so the repair holds. Typical cost is $280-$520 per run. Call (844) 685-6342 for an exact quote - estimates are free.
Palmetto’s river-adjacent location means ambient humidity rarely drops below oppressive levels, and salt-laden air accelerates corrosion inside metal ducts and promotes mold growth in flex duct condensate pockets. Repairs that last inland often fail here within a year if the wrong materials are used. We specify mastic and hardware rated for continuous high-humidity exposure. Call (844) 685-6342 if you smell mustiness near the river - early sealing prevents costlier replacement.
Yes. Belly-duct configurations are common in Palmetto’s manufactured housing stock, and we’ve repaired them for decades. Ground moisture accumulates in the belly cavity, corroding connections and saturating insulation. We access the belly, dry the cavity, seal leaks with mastic, and reinstall with moisture-barrier insulation. Typical range is $380-$620. Call (844) 685-6342 to schedule - we carry the specialized access tools and materials.
No. Sealing over active mold traps spores and moisture, making the problem worse. In Palmetto’s climate, mold in flex duct almost always means the inner liner has sagged or torn, creating a pocket that stays wet. We re-support or replace the damaged section, clean with proper remediation methods, then seal to prevent recurrence. Sealing is the last step, not the first. Call (844) 685-6342 for camera inspection and an honest assessment.
