Fast, Reliable Duct Repair & Sealing Across Lighthouse Point
Duct repair and sealing in Lighthouse Point, FL typically costs $280–$650 for most residential jobs, and we can usually diagnose and quote same-day. If you’re running your AC 10–11 months a year like most Lighthouse Point homeowners, even small duct leaks are costing you serious money on your FPL bill—and pulling humid, salt-laden air into your system.
We’re Charles Rodriguez and the team at Pinnacle Air Duct Cleaning Service Florida, and we’ve been working on duct systems in this specific marine environment for 17 years. We know the difference between a standard Broward County duct job and a Lighthouse Point canal-front home where salt air, persistent humidity, and 1970s flex ductwork create a repair scenario you won’t find inland. When you call (833) 858-4048, you’re talking to Charles directly—he leads every job himself, and he’s probably already worked on a house on your street.
Our Duct Repair & Sealing team covers all of Lighthouse Point’s 33064 zip code, from the finger canals off NE 21st Avenue to the Intracoastal-front homes along Federal Highway. Response time to Lighthouse Point is typically same-day or next-morning, because we keep our equipment and common flex duct sizes stocked for the specific repair patterns we see here.
Why Pinnacle Air Duct Cleaning Service Florida Is Lighthouse Point’s Preferred Duct Repair & Sealing Company
We’ve earned 1,186 verified customer reviews averaging 4.9 stars, and a significant portion of those come from repeat Lighthouse Point customers who’ve watched us solve problems other companies missed. One homeowner on NE 26th Avenue called us after two general HVAC contractors couldn’t stop a persistent mold smell—Charles found a cracked mastic seam behind a salt-corroded access door that was drawing canal-humid attic air into the return. That’s the kind of local pattern recognition you get from 17 years focused on one specialty.
Charles leads every job himself. Not a rotating crew. Not a subcontractor. When you hire Pinnacle, the owner is the technician crawling your attic, which means the accountability stops with the person whose name is on the company. We’ve found that Lighthouse Point’s 1960s–1970s CBS canal-front homes reward this kind of careful, owner-led inspection—their original ductwork has stories to tell if someone knows how to read them.
Our response time to Lighthouse Point averages under 4 hours for calls placed before 2 PM. We carry R6 and R8 flex duct, galvanized access doors with corrosion-resistant gaskets, and Abatement Technologies HEPA equipment on every truck—so we’re not making a parts run while your attic air leaks into the humid Florida afternoon.
Our Duct Repair & Sealing Services in Lighthouse Point
Duct Sealing
Duct sealing in Lighthouse Point isn’t just about stopping air leaks—it’s about preventing the specific failure mode where salt-corroded metal diffusers and grilles create gaps that leak conditioned air while simultaneously drawing in humid attic air. We use mastic sealant and metal-backed tape rated for high-humidity marine environments, not the cheap foil tape that peels in Lighthouse Point’s ambient moisture. A typical duct sealing job for a 1,500–2,500 square foot Lighthouse Point home runs $280–$450, depending on accessibility and how many salt-damaged components need replacement.
Flex Duct Repair
The flex duct inner liners on canal-front homes in Lighthouse Point degrade faster than anywhere else we work in Broward. The saturated air off the finger canals keeps return-air humidity elevated even when your AC is running, and that moisture attacks the plasticized inner liner from the inside out. We’ve opened up flex ducts in Lighthouse Point that looked fine from the outside but tore like wet paper when touched—bio-growth had weakened the material. Our flex duct repair protocol for Lighthouse Point uses thicker R8 insulated flex with improved vapor barriers, and we always inspect the full run because damage is rarely isolated. Replacement sections typically run $180–$340 per run, with full home re-ducting on larger canal-front properties reaching $1,200–$2,800.
Metal Duct Repair
Original metal ductwork in Lighthouse Point’s older homes shows a distinctive corrosion pattern: galvanized access doors and diffuser frames rust at the seams first, creating air leaks that compound the humidity problem. We repair with galvanized steel components and corrosion-resistant gaskets, and we seal with mastic formulated for coastal applications. Metal duct repair in Lighthouse Point homes typically ranges $320–$580, with costs climbing if we need to fabricate custom transitions for odd-sized 1970s plenums.
Duct Insulation
Condensation on duct surfaces is a year-round issue in Lighthouse Point because your ducts never get a true dry-out cycle. We install R8 insulation with intact vapor barriers on new and repaired sections, paying special attention to attic runs where the temperature differential between 55-degree conditioned air and 85-degree attic air creates the worst sweating. Duct insulation work in Lighthouse Point typically runs $200–$480 depending on linear footage and whether we’re wrapping existing metal or insulating new flex runs.
Mastic Sealant Application
Standard mastic cracks prematurely in Lighthouse Point’s salt-air environment. We use a fiber-reinforced mastic sealant rated for coastal HVAC applications, applied 1/8-inch thick at all joints, seams, and connections. On a recent job on NE 26th Avenue, we found original mastic that had cracked from salt-air exposure just 18 months after application by another contractor. Our mastic work is included in standard duct sealing pricing, but standalone mastic touch-up for localized leaks runs $150–$280.
Air Leak Repair
Air leaks in Lighthouse Point homes follow predictable patterns: corroded diffuser connections, cracked plenum seams, and failed flex duct collars at the air handler. We pressure-test to locate leaks, then repair with materials matched to the local environment. Most Lighthouse Point air leak repairs fall in the $220–$420 range.

Trusted Brands We Service in Lighthouse Point
We stock parts and use equipment from Honeywell, Aprilaire, and Abatement Technologies—brands that build for commercial and marine environments, not big-box retail. For Lighthouse Point’s salt-air conditions, we specify Honeywell media air cleaners with corrosion-resistant frames and Aprilaire humidistat controls that help manage the moisture load. We keep common diffuser sizes, flex duct diameters, and galvanized access doors on our trucks because Lighthouse Point’s 1970s housing stock uses dimensions that newer construction has moved away from. That means faster turnaround and no waiting on parts while your system leaks conditioned air into the attic.
Common Duct Repair & Sealing Problems We See in Lighthouse Point Homes
- Salt-air corrosion of metal diffusers and grilles. In Lighthouse Point’s canal-front neighborhoods, duct systems often show accelerated corrosion on metal components like diffusers and access doors within 3–4 years due to salt air, whereas inland homes may go 8–10 years before similar damage. The rust creates gaps that leak conditioned air and draw in humid attic air, compounding both energy waste and moisture problems.
- Flex duct inner liner degradation from persistent humidity. Original flex duct inner liners on canal-front homes degrade faster, tearing when touched during inspections and requiring replacement. The saturated air off the canals keeps return-air humidity elevated even when the AC is running normally, attacking the liner from inside the duct.
- Premature mastic sealant failure. Mastic sealant on joints and seams can crack prematurely in the humid coastal environment, reopening air leaks that were supposedly fixed. We see this frequently on homes where standard interior-grade mastic was applied by contractors unfamiliar with Lighthouse Point’s specific conditions.
- Renovation-addition duct mismatches with poor vapor barriers. Many Lighthouse Point homes have had additions put on over the decades, and the flex duct run to that new room often uses a different era of material with an inferior vapor barrier. These sections sweat first, grow mold first, and fail first—usually right where they connect to the original system.

FAQs — Duct Repair & Sealing in Lighthouse Point
Salt-air saturation and persistent humidity from the finger canals accelerate corrosion on metal components and degrade flex duct liners from the inside out. In Lighthouse Point’s canal-front neighborhoods, duct systems often show accelerated corrosion on metal components like diffusers and access doors within 3–4 years due to salt air, whereas inland homes may go 8–10 years before similar damage. The ambient humidity also prevents ducts from ever fully drying, creating continuous condensation cycles. Call (833) 858-4048 for a free inspection—Charles will show you exactly what’s happening in your specific system.
We replace them. Once mold has colonized the inner liner of flex duct, cleaning doesn’t reliably reach the full depth of the porous material, and residual spores will re-establish. We recently sealed a flex duct leak on a 1970s canal-front home on NE 26th Avenue where the flex duct’s inner liner showed bio-growth just 2 years after a prior cleaning—we replaced the damaged section with thicker R8 insulated flex duct and applied fresh mastic at all joints. Replacement is the only protocol we trust for Lighthouse Point’s humid environment. Call (833) 858-4048 for a free estimate on replacement.
Every 2–3 years for canal-front properties, versus 4–5 years for inland Broward homes. The salt-air exposure and continuous humidity cycle mean mastic cracks, metal corrodes, and flex duct liners degrade faster here. We recommend a visual inspection of accessible ductwork every other year, with full pressure-testing if you notice uneven cooling, rising FPL bills, or musty odors. Call (833) 858-4048 to schedule—estimates are free.
Yes. Leaking return ducts in Lighthouse Point’s humid environment actively pull attic air—often 80+ degrees and saturated with moisture—into your system, raising indoor humidity and creating condensation surfaces inside walls and ceilings. Supply leaks dump conditioned air into the attic, causing your system to overwork and creating negative pressure that draws even more humid air through every crack. The mold risk is real and well-documented in Florida’s coastal construction. Call (833) 858-4048 and we’ll pressure-test your system to find every leak.
Fiber-reinforced mastic sealant rated for high-humidity marine environments, applied 1/8-inch thick at all joints and seams. We don’t use standard foil tape or interior-grade mastic—they fail within 12–18 months in Lighthouse Point’s salt-air conditions. On that NE 26th Avenue job, the prior contractor’s standard mastic had cracked from salt-air exposure in under two years; our coastal-grade application is still holding strong 4 years later. Call (833) 858-4048 to discuss your specific repair needs.
