Fast, Reliable Duct Sealing Across Lighthouse Point
Duct sealing in Lighthouse Point typically runs $450 to $1,200 for a full-system treatment on a standard single-family home, and most jobs are completed within one visit. That’s the honest range we quote before we ever touch a duct. If you’re noticing weak airflow in the far bedrooms, rooms that never quite cool down, or dust settling on furniture within days of cleaning, you’re probably losing conditioned air through leaking ductwork. Call us at (754) 354-3644 and we’ll give you a written price for your Lighthouse Point home before any work begins.
Why Hollis Air Duct Fort Lauderdale Is Lighthouse Point’s Preferred Duct Sealing Company
We’ve spent enough time crawling through Lighthouse Point attics and closets to know exactly what this city’s ductwork looks like after forty or fifty years near the water. The homes here, many of them 1950s through 1980s ranches and coastal-style builds, have duct systems that were installed when AC ran seasonally, not year-round. Now those same ducts push conditioned air for eleven months out of twelve, and the salt-laden breeze off the Intracoastal works on metal seams the whole time.
Roy Castellanos leads our crew, and the standard he set is plain: write the price down before we start, do the work by the book, and leave the site cleaner than we found it. That’s Duct Sealing handled the way it should have been handled the first time. Every job carries our 365-Day Done Right Promise in writing. If a sealed seam fails within a year, we return and make it right at no charge. No argument. No invoice.
Our technicians arrive uniformed and background-checked, and when you call, a live person answers. Always. No voicemail loop, no waiting until Monday to hear back about a musty smell coming from your supply vents.
Styles & brands we work with
Duct Insulation in Lighthouse Point
Duct Insulation in Lighthouse Point isn’t a comfort add-on; it’s a moisture defense. When cool, conditioned air moves through ductwork running through a hot, humid attic or an unconditioned soffit space near the water, the outside of the duct sweats. That condensation soaks into insulation, drips onto drywall, and creates exactly the kind of damp microclimate where mold takes hold. We see it constantly in the original duct runs of Lighthouse Point’s older ranch homes.
Expect to pay $200 to $450 for partial insulation repair around accessible duct sections, and $700 to $1,400 when we’re re-insulating an entire trunk line in a typical Lighthouse Point attic. The price is written down before work starts, and it does not move at the door.
Why Sweating Ducts Matter Near the Intracoastal
A sweating duct isn’t just a nuisance. In Lighthouse Point’s high-humidity air, the moisture that forms on improperly insulated ductwork feeds mold inside the insulation jacket and rust on the duct itself. By the time you see a stain on the ceiling, the problem has usually been active for months.
What We Check Before Insulating
Before we wrap any duct in Lighthouse Point, we inspect the seams and joints underneath. Insulating over a leaking duct just hides the problem and rots the new insulation from the inside. We seal first, then insulate, then verify with a static-pressure reading.
HVAC Duct Sealing in Lighthouse Point
HVAC Duct Sealing in Lighthouse Point is the single most effective repair we do for homes near the Intracoastal, because the salt air here corrodes duct seams in a way inland Broward simply doesn’t experience. Galvanized steel joints rust, tape adhesive dries out and fails, and conditioned air pushes out into attics and soffits instead of reaching your bedrooms. Sealing closes those gaps at the source.
Full-system HVAC duct sealing in Lighthouse Point runs $450 to $1,200 depending on the size of the home and how many linear feet of duct need attention. That includes camera inspection of the main trunk lines, mastic application at failed joints, and reinforcement of corroded seams. We don’t charge per vent and we don’t upsell you halfway through the job.
Mastic vs. Tape: What Actually Holds in Salt Air
Foil tape is fine in a dry, clean environment. On salt-corroded metal in a Lighthouse Point attic, it fails within a season or two. Mastic is a thick, brush-on sealant that cures into a flexible, airtight bond. It’s what we use on every seam, every joint, every pinhole. It’s not the fastest method, but it’s the one that lasts.
Pinhole Leaks: The Silent System Killer
The leaks that cost Lighthouse Point homeowners the most aren’t the obvious gaps at register boots. They’re pinhole leaks along the main trunk line, where years of salt-laden humidity have rusted tiny openings that bleed conditioned air into the soffit. A camera inspection finds them. Mastic seals them. A fogging treatment does neither.
Trusted Brands We Service in Lighthouse Point
Our Lighthouse Point crews work with professional-grade equipment from Rotobrush, Nikro, and filtration products including Honeywell and Guardsman. That matters when you’re sealing ducts in a coastal home, because the negative-air machines we run during sealing capture rust particles and debris before they can blow back into your living space. We stock the mastic, sealants, and filtration media needed for Lighthouse Point jobs on our trucks, so we aren’t running back and forth to a supply house while your AC sits off.
Common Duct Sealing Problems We See in Lighthouse Point Homes
- Rusted galvanized seams on supply trunks. Decades of salt-laden air from the Intracoastal corrode the factory joints on original 1960s and 1970s ductwork until conditioned air bleeds straight into the soffit. The fix is mastic at every compromised seam, not tape.
- Sealed boots with leaky trunks. We’ve seen homes where someone sealed the register boots but left pinhole gaps in the main trunk line. Moist return air still condenses inside the duct, and the homeowner can’t figure out why the problem persists.
- Foil tape failure on corroded metal. Tape doesn’t bond to rust. It looks fine for a month and then peels away at the edges, letting air push out at every joint. Lighthouse Point’s humidity accelerates this failure.
- Rust particles recirculating after a bad sealing job. If the blower motor isn’t HEPA-filtered during sealing, rust debris from corroded ducts gets kicked back into the home. We run negative-air filtration during every sealing job for exactly this reason.

FAQs About Duct Sealing in Lighthouse Point
Lighthouse Point sits right on the Intracoastal Waterway, so the air moving through your duct system carries salt and moisture that inland neighborhoods don’t face to the same degree. That salt settles on galvanized steel seams and accelerates rust formation. Homes built in the 1950s through 1980s, which make up a large share of Lighthouse Point’s housing stock, often still have original ductwork that’s been corroding for forty or fifty years. Call (754) 354-3644 and we’ll camera-inspect your system and show you exactly what’s happening.
Yes, and it’s actually more worth it for Lighthouse Point homes than for inland properties. When your AC runs eleven or twelve months a year, every leak in the duct system bleeds conditioned air into the soffit continuously, not just during a summer peak. A sealed system means the air you’re paying to cool reaches the rooms it’s supposed to cool. For a typical Lighthouse Point ranch, full-system sealing runs $450 to $1,200, and it usually pays for itself in lower cooling bills and fewer hot spots within the first few years.
No. Fogging treats the symptom, not the source. If moisture-laden return air is still pulling into the duct through unsealed seams, the mold and mildew growth will return within months. Sealing closes the entry point for that humid marine air. Once the system is sealed, then a sanitizing treatment can make sense as a finishing step. But fogging without sealing is money spent on a temporary improvement. We’ll give you a written recommendation before any treatment, so you know what’s actually worth paying for.
The supply trunk seams fail first. Those factory joints on the main trunk line are where galvanized coating is thinnest and where salt-laden condensation settles. Once pinholes open up, conditioned air escapes into the attic before it ever reaches your vents. We find this pattern repeatedly in Lighthouse Point homes, especially along Lighthouse Drive and the waterfront streets west of Federal Highway. Camera inspection identifies these leaks before we seal anything.
For homes on or near the Intracoastal, we recommend an inspection every two to three years. Coastal conditions here are harsher than inland Broward, and sealant that’s still solid in Plantation or Sunrise can be failing in Lighthouse Point within a few seasons. After we complete a sealing job, we cover the work for a full year under the 365-Day Done Right Promise. If a seam opens in that window, we return at no charge. Call (754) 354-3644 to schedule an inspection and get a written price.
One Job That Shows What We Mean
We recently sealed a supply duct run in a 1960s ranch on Lighthouse Drive. The original galvanized joints had rusted enough that conditioned air was bleeding straight into the soffit, and the homeowner was running the AC constantly just to hold 78 degrees. After a camera inspection found gaps along the supply trunk, we applied mastic and reinforced the corroded seams, then rebalanced the air handler static pressure to specification. That’s the difference between sealing ducts and actually fixing them. You don’t have to understand static pressure. You just have to know it’s done right. That’s our job.
