Fast, Reliable Duct Sealing Across Sunrise
Duct sealing in Sunrise typically costs $850 – $2,400 for a whole-home system, depending on home size and the condition of the existing ductwork. Most jobs are completed in a single day. If your AC runs constantly but rooms still feel warm, or you see dust building up on registers within days of cleaning, the problem is likely leaking ducts, not the unit itself. Hollis Air Duct Fort Lauderdale has been sealing ducts in Sunrise long enough to know exactly what these older systems need. Call (754) 354-3644 for a written price before any work begins.

Why Hollis Air Duct Fort Lauderdale Is Sunrise’s Preferred Duct Sealing Company
Sunrise homeowners call us because we write the price down before we touch anything. That matters in a trade where a low teaser quote can turn into a far bigger invoice once the tech is inside your attic. Every job we do in Sunrise, from West Sunrise to the neighborhoods around Sawgrass Mills, gets the same treatment: a camera inspection, a written price, and a 365-Day Done Right Promise in writing. If the seal fails within a year, we come back and fix it at no charge. No negotiation. No fine print.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. They also know what they’re looking at when they open up a 1980s flex duct system in Sunrise Golf Village, just as they do on our Dryer Vent Cleaning in Sunrise. That local knowledge is the difference between a crew that cleans dust and a crew that finds the crushed run that’s been silently costing you money for years. Roy Castellanos runs the team, and the standard he enforces is simple: show up on time, price it in writing, do it by the book, leave the site clean.

Duct Repair in Sunrise
Duct repair in Sunrise usually means one of three things: replacing collapsed flex runs, rebuilding crumbling duct board plenums, or sealing joints that have separated after 30 – 40 years of Florida humidity. Homes built between 1970 and 2000 dominate this city, and many still have the original ductwork. We see runs that have been crushed inside concrete block chases, sagging under their own weight, and plenums that shed fibrous particles every time the blower cycles on. Repair work in Sunrise typically runs $350 – $900 for a single collapsed run, while a full plenum rebuild ranges $600 – $1,400 depending on access.
Camera Inspection Before Any Cutting
We don’t guess. Before we recommend any repair, we run a camera through the supply and return lines to locate every breach, crushed section, and disconnected joint. You see the footage. We explain what it means and what it costs to fix.
Crushed Runs and Collapsed Sections
Flex duct installed in the 1980s was never designed to last 40 years in a Florida attic. Heat, humidity, and gravity do their work. When a run collapses, the air your AC produces never reaches the register. That’s wasted electricity and hot rooms.
Air Duct Sealing in Sunrise
Air duct sealing in Sunrise is the fix most homeowners actually need, even if they called us for a cleaning. Leaking ducts can lose 20 – 30% of conditioned air into the attic or wall cavities, which means your AC runs longer and your rooms still feel muggy. Sealing typically costs $850 – $2,400 for the whole system, with most Sunrise homes falling in the $1,100 – $1,800 range. The exact number depends on duct length, accessibility, and how many leaks the camera finds.
Negative-Pressure Mastic Sealing
We use a system that holds the ducts under negative pressure while injecting a mastic formula into every gap, crack, and separated joint. The material fills the breach from the inside and cures in place. It’s the same approach commercial crews use, applied to your 1,800-square-foot Sunrise home with the same standard of care.
Why Duct Tape Never Lasts
Hardware-store duct tape dries out and peels within a season or two in a Florida attic. Mastic sealing, applied correctly, bonds to the duct material and stays flexible for years. That’s why our work carries a one-year written promise, not a shrug.
Trusted Brands We Service in Sunrise
We work on all major equipment and filtration brands found in Sunrise homes, including Honeywell, Aprilaire, and Guardsman filtration systems. Because we stock common replacement parts and sealants on our trucks, most standard repairs and sealing jobs are completed the same day we arrive. You don’t wait a week for a part to ship. The material we use for sealing is professional-grade, the same class of product used on commercial jobs, and it’s applied by technicians who know the difference between a proper mastic seal and a cosmetic one.

Common Duct Sealing Problems We See in Sunrise Homes
- Crumbled duct board supply plenums. Many older Sunrise homes, especially in Sunrise Golf Village and surrounding neighborhoods, have original duct board plenums that disintegrate when disturbed. An inexperienced tech can turn a small leak into a full replacement by poking around without care.
- Collapsed flex runs hidden in block chases. Concrete block construction means ducts often run through narrow chases that trap heat. Over decades, the inner liner separates and collapses. The register looks fine, but the airflow is gone.
- Separated joints from summer downpours. Sunrise gets intense afternoon thunderstorms from June through September. Moisture finds its way into any gap in the ductwork, and repeated wet-dry cycles loosen joints and invite mold around registers.
- Organic debris from the Everglades. Sunrise sits closer to the Everglades than most South Florida cities. That proximity means more organic matter in the air, which settles in ducts and clings to interior surfaces, especially when duct leaks pull unfiltered attic air into the system.

FAQs About Duct Sealing in Sunrise
The original flex ductwork installed in those decades was rated for roughly 15 – 20 years, and most Sunrise homes are now well past that. Add in 40 years of attic heat, high humidity, and the weight of condensation, and the inner liners separate, the outer jackets tear, and the runs collapse. The concrete block chases common in Sunrise homes trap heat and make it worse. If your home was built before 2000 and the ducts haven’t been inspected, there’s a good chance you’re losing conditioned air right now. Call (754) 354-3644 and we’ll run a camera through the system and show you what’s there.
If mold is present, sealing alone isn’t the right fix. Sealing damp, contaminated ducts traps the problem inside. We assess the moisture source first, then recommend whether the duct section needs replacement before sealing. In Sunrise, the combination of Everglades proximity and summer downpours means mold growth around registers and inside ducts is common. We’ll give you a straight answer on what needs to happen and what it costs. Call (754) 354-3644 for a written assessment.
Yes. Sunrise Golf Village and other older Sunrise neighborhoods are where we see the most original duct board plenums, and we’re familiar with how carefully they need to be handled. Many are brittle enough that rough handling turns a sealable leak into a full plenum rebuild. We inspect first, photograph what we find, and only then recommend a repair path. The price is written down before we start.
We run a high-resolution camera through the supply and return lines from the register side, so there’s no need to open walls. The camera identifies crushed sections, separated joints, and breaches. For the sealing step, we use a negative-pressure system that pulls the mastic formula into every gap from the inside. It’s non-invasive and far more effective than taping seams you can see from the outside. Call (754) 354-3644 for a free estimate and camera inspection quote.
When the Department of Energy average leakage rates apply, sealing can recover 20 – 30% of conditioned air that was being lost into the attic or chases. In Sunrise, where AC runs most of the year due to the humid subtropical climate, that’s real money. The exact savings depend on how much your system was leaking and what your per-kWh rate is, but homeowners regularly report their AC stops short-cycling and rooms hold temperature longer. The 365-Day Done Right Promise means if the seal fails within a year, we return and redo it at no charge. Call (754) 354-3644 to schedule a camera inspection and get a written price.
What a Sunrise Duct Sealing Crew Actually Sees
When we open up a 1980s flex duct system in Sunrise, we’re not surprised by what’s inside. We expect to find collapsed runs, separated joints, and duct board plenums that shed material every time the blower starts. In one recent job in a Sunrise Golf Village home built in 1984, our crew found crushed flex ducts in three runs and a supply plenum that was disintegrating at the connection points. We sealed the system using our negative-pressure mastic injection method after confirming every breach with camera footage. The homeowners reported their AC no longer short-cycles and the musty smell near the registers is gone.
That job is not unusual. Roughly 65 – 70% of homes in Sunrise were built between 1970 and 2000 with original flex ductwork, and many still have duct board plenums that crumble when disturbed. You won’t find that condition as often in Fort Lauderdale, where the housing stock is newer or has been renovated more aggressively. Sunrise is different, and the duct problems here are specific. If your home is in Weston, Sawgrass, or the neighborhoods around the BB&T Center, and it was built before 2000, this is your reality. The good news: it’s fixable, and we can tell you exactly what it costs before we start.
