Fast, Reliable Duct Repair & Sealing Across Pompano Beach
Duct repair and sealing in Pompano Beach typically runs $180-$650 depending on access and damage extent, and most of our Duct Repair & Sealing jobs are completed in a single visit. We’re familiar with the salt-air corrosion that attacks ductwork within a mile of the Atlantic and the Intracoastal Waterway, and we stock galvanized hardware and mastic sealant specifically for coastal conditions. If you’re in Pompano Beach and noticing uneven cooling, musty odors, or rising electric bills, call us at (844) 685-6342. We answer live, 24 hours a day.
We’ve worked Pompano Beach homes for over 42 years, from the 1960s concrete-block houses near Atlantic Boulevard to the tract subdivisions west of I-95. That history matters because the ductwork failures we see here don’t look like what fails in Orlando or even in Coconut Creek fifteen minutes inland. Salt, humidity, and decades of near-continuous operation create a specific repair profile. We know what to look for, where to look, and how to fix it so it stays fixed.

Our Duct Repair & Sealing Services in Pompano Beach
Duct Sealing with Mastic Sealant
Mastic sealant is our first-line repair for separated duct joints and small gaps in Pompano Beach’s older homes. Unlike foil tape, which degrades in attic heat and salt air within a few seasons, mastic forms a permanent flexible bond that moves with the ductwork. We apply it by hand at every joint, collar, and penetration, then verify with a camera that the seal is complete. In Pompano Beach’s humid climate, a proper mastic seal prevents conditioned air from leaking into hot attics and stops unfiltered, moisture-laden air from being drawn into the system. Typical mastic sealing work in Pompano Beach runs $180-$340 for accessible trunk lines.

Flex Duct Repair
Flex duct in western Pompano Beach ZIPs, particularly the 33063-33068 area, spends its life in attics that reach 140°F in summer. The plastic inner liner becomes brittle, cracks at bends and junctions, and separates from collars. We replace damaged flex runs with new insulated duct, secure with mechanical straps rather than tape, and seal with mastic at every connection. We recently sealed leaking flex duct in a 1970s CBS home in the 33064 zip code near the Intracoastal Waterway. The original foil-faced duct board had corroded at the collars from salt air, causing a 3-inch separation at the main trunk; we used mastic sealant and galvanized steel flanges to restore integrity, eliminating a 15% air loss that was making the master bedroom 8°F warmer than the rest of the house. Flex duct repair in Pompano Beach typically costs $220-$480 depending on attic access and length of run.

Metal Duct Repair
Metal ductwork within a mile of Pompano Beach’s coast corrodes faster than anywhere inland. Salt-laden air attacks galvanized steel collars, flanges, and duct board facings, creating pinholes and separation gaps that bypass your air filter entirely. We cut out corroded sections, fabricate replacement metal from heavier-gauge stock, and coat new installations with corrosion-resistant primer. Where original duct board has failed, we transition to solid metal where practical. Metal duct repair in Pompano Beach runs $280-$650, with coastal properties often at the higher end due to more extensive corrosion.

Duct Insulation Replacement
Insulation on attic ductwork in Pompano Beach compresses, gets torn by rodents, or becomes saturated with condensation. Once the insulation barrier fails, cold air hits hot metal and sweats, accelerating mold growth and further duct degradation. We strip failed insulation, treat any surface mold, and re-wrap with formaldehyde-free fiberglass or closed-cell foam insulation rated for South Florida’s humidity. Proper insulation pays for itself in reduced run times and prevents the moisture problems that are endemic to Pompano Beach’s climate.

Trusted Brands We Service in Pompano Beach
We repair and seal ductwork connected to all major HVAC brands, and we specify Honeywell and Aprilaire components for replacement dampers, registers, and filtration upgrades where the original hardware has failed. Our trucks carry galvanized steel flanges, mastic sealant, and flex duct from Nikro and Abatement Technologies so we’re not waiting on parts for a second visit.

Most repairs are completed in one trip because we’ve learned what this city’s ductwork actually needs.
Common Duct Repair & Sealing Problems We See in Pompano Beach Homes
- Salt-air corrosion of metal collars and flanges. Properties within a mile of the Atlantic or Intracoastal Waterway see galvanized steel duct hardware corrode years faster than inland. The resulting gaps pull unfiltered, humid air directly into your system, bypassing the filter entirely.
- Fiberglass duct board delamination in east-side condos. In Pompano Beach’s east-side condo buildings along Atlantic Boulevard, fiberglass-lined duct board from 1970s construction commonly delaminates due to salt-air humidity cycles, shedding fibers directly into conditioned air. This goes undetected in snowbird-owned units during summer vacancies, making fall the busiest season for urgent duct calls.
- Attic flex duct degradation in western subdivisions. Flex duct in 1970s-80s tract homes west of I-95 cracks and separates at junctions after decades of extreme attic heat exposure. The damage is often hidden above insulation and only detected when rooms stop cooling evenly.
- Mold-colonized duct interiors from stop-start HVAC cycles. Pompano Beach’s large stock of 1960s-1980s condominiums along the A1A and Intracoastal corridor, many owned by seasonal snowbirds, means HVAC systems routinely sit idle through the brutally humid South Florida summer and are then cranked back up in the fall. That stop-start cycle in a marine-humid environment creates ideal conditions for mold colonization inside ductwork, making Pompano Beach’s aging condo units a particularly high-risk segment that neighboring inland Broward cities simply do not have at the same scale.

FAQs - Duct Repair & Sealing in Pompano Beach
Yes. Salt-laden air within roughly a mile of the Atlantic or Intracoastal Waterway corrodes galvanized metal duct collars, flanges, and hardware faster than anywhere inland in Broward County. We consistently find pinhole corrosion and separation gaps in east-side Pompano Beach buildings that simply don’t occur at the same rate in Margate or Coconut Creek. Once metal corrodes, the gap pulls unfiltered, humid air into your system. Call (844) 685-6342 and we’ll camera-inspect your ductwork to show you exactly what’s happening inside.
Snowbird units sit vacant through Pompano Beach’s most humid months with no air circulation, allowing mold to colonize duct interiors and fiberglass duct board to absorb moisture. When the system fires up in October or November, that mold blasts into the living space and degraded duct board sheds fibers. Fall is our busiest season for urgent duct calls from returning seasonal residents. If you own a seasonal unit, we recommend a pre-season inspection and sealing before you return. Estimates are free.
Very common in east-side condos and CBS homes built from the 1960s through the 1980s. The problem isn’t the material itself, it’s that decades of salt-air humidity cycling in Pompano Beach’s climate cause the inner fiberglass liner to delaminate. Once that happens, fibers enter your breathing air and the duct loses structural integrity. We replace failed duct board with solid metal or properly insulated flex where appropriate. Camera inspection reveals the condition without guesswork.
Mastic sealant applied by hand at every joint, collar, and penetration, backed by mechanical fasteners rather than tape. In Pompano Beach’s older concrete-block homes, the original flex duct and duct board have often shifted slightly over decades, creating gaps at connections. Mastic remains flexible, seals irregular surfaces, and outlasts foil tape in attic heat. We verify every seal with a camera before we leave. Most CBS home sealing jobs run $280-$450 for accessible systems.
Absolutely. Attics in western ZIPs like 33063-33068 regularly reach 130-140°F in summer, which degrades the plastic inner liner of flex duct and causes insulation to sag or compress. Cracks form at stress points and junctions, often hidden above blown insulation. We replace degraded flex with new insulated duct rated for high-temperature attics, secure with mechanical straps, and seal with mastic. If your west Pompano Beach home has rooms that won’t cool evenly, attic flex duct failure is a likely cause. Call (844) 685-6342 for a camera inspection and upfront quote.
