We’ve been serving Fort Lauderdale homeowners since 2012, and we know the local conditions that ruin ductwork here. The canal-front humidity in Lauderdale Isles, the salt-laden air pressing in from the Atlantic two miles east, the aging flex duct in 1970s ranch homes off Sunrise Boulevard - these aren’t abstract problems for us. Our technicians carry the right equipment for tight attic clearances in older Fort Lauderdale neighborhoods and for shared HVAC risers in high-rise condos along the Intracoastal. We’ll be there when we say.
Why Bellows Air Duct & Vent Co. Is Fort Lauderdale’s Preferred Duct Repair & Sealing Company
Fort Lauderdale homeowners call us because we’ve built our reputation on showing up and doing what we promised. Our 90-Day Done Right Promise is stamped on every job - if it’s not right, we make it right, no paperwork, no arguing. That guarantee has kept us in business for over 14 years, and it’s why customers from Victoria Park to Coral Ridge refer their neighbors.

Our background-checked, uniformed technicians complete most duct repairs in a single visit, and every job is camera-inspected before and after so you see the condition of your system, not just take our word for it.
Our upfront pricing means the number we give on the phone is the number on the invoice. No bait coupons, no price changes when we walk through the door. That’s been our practice since Ray Castillo founded Bellows Air Duct & Vent Co. in 1984, and it’s not changing.
Our Duct Repair & Sealing Services in Fort Lauderdale
Duct Sealing with Mastic Sealant
Fort Lauderdale’s near-continuous HVAC operation - 10 to 11 months a year - means every leak in your ductwork is a leak you pay for daily. In canal-front neighborhoods like Lauderdale Isles and Imperial Point, we routinely find supply boots pulling away from drywall, creating gaps that dump conditioned air into humid attics. We seal these connections with professional-grade mastic sealant, not duct tape, which fails within months in our climate. Mastic remains flexible and airtight through decades of heat cycles and humidity exposure. For homes near the water, this isn’t an upgrade - it’s the baseline for keeping mold out and your energy bills down.
Flex Duct Repair and Replacement
The core Fort Lauderdale housing stock - concrete-block homes built from the 1950s through the 1970s - was originally fitted with fiberglass flex duct that turns brittle after 20 to 30 years of humidity cycling. We recently tackled a duct repair in a 1970s concrete-block home on a canal in Lauderdale Isles. The owner complained of musty odors and high energy bills. Upon inspection, we found brittle fiberglass flex duct and black mold at supply boot edges. We replaced the damaged flex duct, sealed all connections with mastic, and applied an antimicrobial treatment - restoring airflow and eliminating the mold source. This is common work for us in ZIP codes 33307 through 33310.
Metal Duct Repair
Salt-laden Atlantic air corrodes sheet-metal duct connections and drain pans faster in Fort Lauderdale than in any inland Florida market we serve. Rust particulate enters the airstream when sealing is neglected, aggravating allergies and coating evaporator coils. We cut out corroded sections, fabricate replacement fittings, and seal with mastic and reinforced mesh for a repair that holds. In beachside corridors like 33308, where the ocean breeze carries salt continuously, we inspect metal connections as standard practice during every service call.
Duct Insulation and Air Leak Repair
Uninsulated or poorly insulated ductwork in Fort Lauderdale attics sweats profusely during our humid summers. That condensation saturates ceiling drywall, breeds mold, and reduces R-value to nearly nothing. We install foil-faced fiberglass insulation or closed-cell foam wraps rated for our climate zone, sealing every seam to prevent vapor infiltration. In townhomes and condos with limited attic access, we work through carefully placed access panels and repair them to match - no open holes left behind.

Trusted Brands We Service in Fort Lauderdale
We stock parts and specify equipment from Abatement Technologies, Rotobrush, and Nikro - the same brands serious HVAC contractors use when they’re installing systems meant to last in coastal Florida conditions. For duct sealing and antimicrobial treatment, we use professional-grade mastic and EPA-registered sanitizers formulated for humid climates, not hardware-store substitutes. Keeping common repair components on our trucks means faster turnaround for Fort Lauderdale customers. Most jobs are completed in a single visit, and we coordinate with building management for condo repairs so you’re not stuck waiting on approval for access to shared risers.
Common Duct Repair & Sealing Problems We See in Fort Lauderdale Homes
- Mold at supply boot edges in canal-front homes. In neighborhoods like Lauderdale Isles and Imperial Point, attic relative humidity routinely exceeds 85% over water-level slabs. Flex duct sweats on the outer liner, and black mold colonizes supply boot edges. Cleaning alone is rarely sufficient here. Duct sealing with mastic plus antimicrobial treatment is the practical minimum to prevent rapid recontamination.
- Corroded metal connections from salt air. The Atlantic sits only 2-3 miles east of most Fort Lauderdale ZIP codes. Salt-laden air rusts sheet-metal duct seams, air-handler drain pans, and flanges faster than inland markets. Rust particulate enters the airstream, degrading indoor air quality and coating coils. Regular inspection and sealing of metal connections prevents this cascade.
- Shared HVAC riser leaks in condos and townhomes. High-rise towers along the beachside corridor and mid-rise buildings throughout 33304, 33305, and 33308 contain shared ductwork between units. Unrepaired leaks allow conditioned air and odors to migrate between neighbors. These repairs require specialized scoping equipment and building-management coordination - failure to scope can leave leaks undetected between walls.
- Snowbird vacancy mold cycles. Fort Lauderdale’s large seasonal population leaves homes sealed and minimally ventilated through the hot, humid summer. Ducts sit in warm stagnant air for weeks. Returning homeowners often discover mold that cleaning alone can’t fix. Sealing boots and applying antimicrobial before departure, or upon return, is the minimum scope to break the cycle.

FAQs - Duct Repair & Sealing in Fort Lauderdale
Duct sealing is essential in canal-front homes because ambient attic humidity above 85% causes flex duct sweating and mold colonization at supply boot edges, making sealing with mastic and antimicrobial treatment a routine necessity rather than an optional add-on. In neighborhoods like Lauderdale Isles and Imperial Point, we’ve found that unsealed boots recontaminate within one humid season. Call (844) 685-6342 for a free inspection - we’ll show you the condition with our camera system.
Yes, high-rise condo duct repairs require specialized scoping equipment and building-management coordination to access shared HVAC risers and detect leaks between units. Our technicians carry borescope cameras and coordinate with property managers for access to mechanical rooms and common chases. Beachside towers in 33304, 33305, and 33308 are a regular part of our Fort Lauderdale service area. Call (844) 685-6342 to schedule - we handle the logistics.
Salt-laden Atlantic air corrodes sheet-metal duct connections, flanges, and air-handler drain pans faster than in any inland Florida market we serve, and rust particulate enters the airstream when sealing is neglected. The ocean sits only 2-3 miles east of most Fort Lauderdale ZIP codes, so this is a year-round factor, not just a beachside problem. We inspect metal connections as standard practice and seal or replace corroded sections before rust spreads. Call (844) 685-6342 for an assessment.
Yes, sealing supply boots and applying antimicrobial treatment before summer departure is the most effective step to prevent mold growth during months of minimal ventilation and stagnant humid air. Returning homeowners who skip this step often find mold that requires far more extensive remediation. We coordinate pre-departure appointments for seasonal residents and can schedule return inspections in the fall. Call (844) 685-6342 to book before you head north.
We use professional-grade mastic sealant, EPA-registered antimicrobial treatments formulated for humid climates, and equipment from Abatement Technologies, Rotobrush, and Nikro for inspection and repair work.
