We’ve been driving the same Lighthouse Point streets for over 42 years, from the canal-front CBS homes along NE 27th Avenue to the townhomes near the Intracoastal. Our Duct Repair & Sealing team knows the local housing stock, the salt-laden air that blows in off every canal, and the tight access constraints that make standard repair equipment useless in half the attics here. We’re familiar with the neighborhood. We’ll be there when we say.
Why Bellows Air Duct & Vent Co. Is Lighthouse Point’s Preferred Duct Repair & Sealing Company
Homeowners in Lighthouse Point call us because we’ve earned a reputation for showing up, telling the truth about what the ductwork actually needs, and standing behind the work. Our 90-Day Done Right Promise is stamped on every job, no paperwork required. If it’s not right, we make it right.
Our response time to Lighthouse Point is same-day or next-day in most cases. We keep compact equipment on every truck for the tight clearances and alley-load access that define this city’s housing. Calls are answered by a live person 24 hours a day, not a voicemail tree.
We understand the local conditions that destroy ductwork here. The salt-laden, near-saturated coastal air infiltrating attics and return cavities accelerates mold colonization, fiberglass liner degradation, and metal plenum corrosion at a rate that distinguishes Lighthouse Point sharply from even neighboring Pompano Beach or Deerfield Beach homes just a mile or two inland. This isn’t theoretical for us. We’ve pulled apart enough corroded plenums in 33064 to know the pattern by heart.
Our Duct Repair & Sealing Services in Lighthouse Point
Duct Sealing
Leaky duct joints in Lighthouse Point attics don’t just waste cooled air. They draw in the humid, salt-heavy attic air that accelerates corrosion and biological growth throughout the system. We seal with mastic sealant, not tape, because tape fails within months under the moisture cycling that defines this climate. A typical duct sealing job in Lighthouse Point runs $180-$340 for accessible supply and return joints in a single-zone system. We camera-inspect before and after so you see the difference.
Flex Duct Repair
The fiberglass-lined flex duct installed in most Lighthouse Point homes between the 1950s and 1980s deteriorates predictably. Decades of moisture cycling in hot, unconditioned attics cause the liner to shed particulates into your air supply. On NE 31st Place, we sealed a leaking return plenum in a 1970s canal-front CBS home where salt-laden attic air had corroded the metal joint so badly that condensation was dripping onto the fiberglass liner. We applied mastic sealant to the plenum seam and replaced a section of flex duct with insulated R-8 to stop the air leak and prevent further moisture intrusion. Flex duct repair in Lighthouse Point typically costs $220-$480 depending on accessibility and length.
Metal Duct Repair
Metal supply plenums in Lighthouse Point corrode faster than almost anywhere else in Broward County. Canal breezes carry salt particles that settle on metal duct joints, accelerating galvanic corrosion and creating pinhole leaks that reduce system efficiency and introduce attic contaminants. We repair or replace corroded metal sections with corrosion-resistant materials and seal all joints with mastic. Metal duct repair in Lighthouse Point generally runs $280-$650, with plenum replacement at the higher end of that range.
Duct Insulation
Uninsulated or poorly insulated ductwork in Lighthouse Point attics loses efficiency immediately. The extreme temperature differential between 140-degree attic air and 55-degree conditioned supply air creates condensation, which compounds the salt-corrosion problem. We install R-8 insulated flex duct and wrap existing metal with proper insulation barriers. This is particularly critical in the 1950s-80s CBS homes that dominate the local housing stock, where original insulation has long since degraded.
Mastic Sealant Application
We emphasize mastic sealant on every Lighthouse Point job because it’s the only sealing method that survives this environment. Duct tape dries and fails within a single cooling season here. Mastic remains flexible, fills irregular gaps at corroded metal joints, and creates a permanent air barrier. We apply it by brush and trowel in tight attic chases where spray equipment won’t fit.

Trusted Brands We Service in Lighthouse Point
We repair and seal duct systems connected to all major HVAC brands, and we stock parts from Abatement Technologies, Rotobrush, and Nikro for fast turnaround on local jobs. Our technicians carry portable sealing kits and compact inspection cameras from these manufacturers specifically for the tight-access attics common in Lighthouse Point townhomes and canal-front properties. Most repairs don’t require a return trip because the right equipment and the right parts are on the truck from the start.
Common Duct Repair & Sealing Problems We See in Lighthouse Point Homes
- Salt-laden air from canal breezes accelerates metal plenum corrosion at duct joints. The corrosion causes air leaks that reduce HVAC efficiency and draw in humid attic air, creating a feedback loop of moisture damage and energy waste. We see this pattern far more often in Lighthouse Point than in inland Pompano Beach just a mile west.
- Fiberglass duct liner in 1950s-80s homes sheds particulates due to decades of moisture cycling. The degraded liner releases visible dust and debris into living spaces every time the system cycles. Full encapsulation with mastic sealant, not tape, is required to prevent further shedding and contain existing deterioration.
- Tight alley-load and townhome access limits standard repair equipment. Many Lighthouse Point properties have narrow attic chases, low crawlspaces, or restricted entry points that make full-sized equipment impossible. Our crews use compact tools and portable sealing kits specifically configured for these constraints.
- Continuous AC operation year-round accelerates biological growth in duct interiors. Lighthouse Point’s extreme coastal humidity and narrow peninsula geography keep systems running constantly, accumulating mold, salt deposits, and moisture-related debris on a much shorter cycle than national cleaning-interval guidelines assume.

FAQs - Duct Repair & Sealing in Lighthouse Point
Yes. The salt-laden air drawn into return systems and attic spaces in Lighthouse Point corrodes metal plenums and fosters mold on duct liner at a rate far worse than in inland Pompano Beach just a mile west. We’ve replaced plenums in 15-year-old Lighthouse Point homes that showed corrosion equivalent to 30-year-old inland systems. If your home is on or near a canal, we inspect for salt damage as a standard part of every estimate. Call (844) 685-6342 to schedule a free inspection.
Often yes, if the flex duct itself is structurally intact and the problem is primarily at the joints. We apply mastic sealant to all connections and encapsulate degraded liner to stop particulate shedding. If the flex duct has collapsed, torn, or developed extensive internal mold, replacement of the affected section is the only lasting solution. A camera inspection tells us which approach applies to your system. Estimates are free - call (844) 685-6342.
We carry compact, portable sealing kits and inspection cameras specifically for tight Lighthouse Point attics and crawlspaces. Our technicians are trained to work in confined chases where standard equipment won’t fit. We assess access during the free estimate and bring the right tools for your specific layout. Most townhome repairs are still completed in a single visit.
Mastic sealant is substantially better. Duct tape adhesive fails within months under the humidity and temperature cycling of a Lighthouse Point attic, and it does nothing to seal irregular gaps at corroded metal joints. Mastic remains flexible, fills gaps permanently, and withstands the moisture load that defines this environment. We use mastic on every Lighthouse Point job and do not consider duct tape an acceptable primary sealant here.
Given the continuous AC operation and extreme salt-humidity load, we recommend a professional inspection every 2-3 years for Lighthouse Point homes, or sooner if you notice uneven cooling, rising energy bills, or visible dust from vents. Our $89 Seasonal Tune-Up includes a basic duct inspection. For homes on canal lots with known corrosion issues, annual checks are prudent. Call (844) 685-6342 to set up a schedule that fits your property.
