Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Sunrise
We dispatch to Sunrise from our Miami-area office, and crews are usually on site within the same day you call. If you’re in Sunrise Golf Village, Sawgrass Lakes, or anywhere along Oakland Park Boulevard, we know the route and we know what we’ll find when we get there. Most Sunrise homes were built between the 1960s and 1990s, and the ductwork in those houses has had decades to separate, corrode, or flood. That’s not a guess. We’ve opened enough return plenums in Sunrise to know the pattern. Call (361) 326-5060 and we’ll put a written price in front of you before any work starts.
Why Hollis Air Duct Cleaning Is Sunrise’s Preferred Duct Sealing Company
We’ve been doing this since 2004 as part of the Garrison Partners family, and our Duct Sealing team has worked in Sunrise long enough to recognize the specific failure modes that show up here. The 1960s ranch houses near the Sunrise Country Club, the low-rise condos off Sunset Strip, the Sawgrass Lakes subdivisions from the ’90s, each has its own duct story. We don’t walk in cold.
Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the quoted window, price in writing, do the job by the book, leave the site clean. Every repair carries our 365-Day Done Right Promise in writing. If the seal fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a verbal assurance you chase down later. It’s on the paperwork.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. No waiting until Monday.
Duct Sealing Services in Sunrise
Duct Sealing Services in Sunrise address a problem most homeowners don’t know they have until the electric bill climbs or a room won’t cool. We seal supply and return ductwork using mastic and reinforced mesh on metal runs, and proper closure systems on flex duct. The goal is simple: air you’ve already paid to condition should reach the rooms you want it in, not leak into your attic, crawl space, or the soil under your slab. In Sunrise, a typical whole-house duct sealing job runs $850 – $1,800 depending on system size, accessibility, and whether we find disconnected or flooded sections that need repair before sealing can hold.
Leak Detection and Pressure Testing
We start with a duct blaster test or pressure measurement to quantify what you’re losing. In Sunrise’s older homes, we regularly see 25 – 40% leakage on original systems. That number goes on the report we give you, along with the locations. No guesswork.
Mastic Sealing for Metal and Fiberglass Ducts
We brush on duct sealing mastic, a water-based compound that stays flexible and bonds to galvanized metal, fiberglass board, and properly prepared flex duct. Unlike foil tape, which peels under constant condensation, mastic cures to a permanent seal. In Sunrise’s year-round cooling climate, that matters.

Duct Insulation in Sunrise
Duct Insulation in Sunrise is often the missing half of the fix. Sealing stops air loss, but uninsulated ductwork in a hot attic or flooded chase still bleeds temperature. We wrap repaired and sealed trunks with Guardsman insulation wrap and install proper R-value barriers where the original builder skipped them or where condensation has destroyed the facing. A typical duct insulation job in Sunrise runs $600 – $1,400 for a single-family home, depending on linear footage and whether we need to replace water-damaged insulation before wrapping. Low-rise condos with attic or chase access usually fall on the lower end; slab-on-grade homes with buried ducts may need more extensive remediation.
Condensation Control in Humid Climates
Sunrise’s tropical monsoon climate means cold supply ducts sweat almost year-round. We install vapor barriers and proper insulation facing to prevent that moisture from reaching the duct surface. Without this step, sealed ducts grow mold inside the wrap. We’ve seen it.
Insulation Replacement After Water Damage
When groundwater intrusion has saturated the original insulation, we remove it, treat the duct surface for microbial growth, seal, then re-insulate. The new wrap goes on dry ductwork, not over wet fiberglass. Doing it in the right order is what makes the fix last.
Trusted Brands We Service in Sunrise
We stock parts and materials from Nikro, Honeywell, Aprilaire, and Abatement Technologies, the same brands commercial crews specify. For Sunrise homeowners, that means we don’t order parts from a warehouse three counties away and make you wait. Our vans carry mastic, mesh, Guardsman wrap, and filtration components for the common duct configurations we see in 1960s – 90s Sunrise construction. If your system uses Honeywell media filters or Aprilaire whole-house filtration, we can assess how duct leakage is bypassing that equipment and fix the path. Fast turnaround because the material is already on the truck.
Common Duct Sealing Problems We See in Sunrise Homes
- Groundwater intrusion through slab cracks. After heavy summer rains, Sunrise’s high water table floods subterranean return plenums in slab-on-grade homes. Standing water corrodes galvanized metal ducts and creates new leaks that bypass surface sealant. Sealing alone fails here; we pair it with moisture remediation.
- Disconnected original ducts in Sunrise Golf Village. The 1960s – 80s galvanized supply runs under slab floors separate at joints or crush under settling soil. Foil tape can’t bridge a half-inch gap; we open the chase, rejoin the runs, and seal with mastic and mesh.
- Crushed flex duct in low-rise condos. Original flex runs in older Sunrise condos get compressed during renovation or by storage in attic spaces. The section is flattened and airless. We replace the damaged run, then seal the new connection properly.
- Sealant failure from constant condensation. Year-round cooling in Sunrise means cold ducts stay wet. Cheap sealants peel or grow mold before they cure. We use mastic rated for wet application and verify the cure before closing the chase.
Pricing for Duct Sealing in Sunrise, FL
A typical whole-house duct sealing in Sunrise runs $850 – $1,800. Duct insulation alone runs $600 – $1,400. Combined sealing and insulation for a full system usually falls between $1,200 and $2,800. What moves you within those ranges: system size (a 3-ton single-stage versus a 5-ton zoned system), whether we need to repair or replace disconnected sections first, and whether groundwater intrusion requires moisture remediation before sealing can hold.

FAQs About Duct Sealing in Sunrise
Sunrise’s combination of 1960s – 90s construction, slab-on-grade foundations, high water table, and year-round cooling creates conditions that destroy ductwork faster than in drier, newer cities. Groundwater floods plenums, constant condensation corrodes metal, and decades of use separate original joints. Sealing is maintenance here, not an upgrade. Call (361) 326-5060 for a free inspection.
We run a camera through the duct system and perform pressure testing to locate drops in airflow. In Sunrise Golf Village, we expect to find disconnected galvanized runs under the slab and standing water in returns after storms. The camera shows us the gap; the pressure test measures how much air you’re losing. Call (361) 326-5060 to schedule.
No. Sealing over wet ductwork guarantees failure. We pump out standing water, dry the plenum with commercial air movers, treat for microbial growth, then seal. In Sunrise, this sequence is standard, not optional. The seal only holds on clean, dry metal. Call (361) 326-5060 and we’ll assess whether moisture remediation is needed.
We use Nikro agitation and negative-air equipment for cleaning before sealing, Honeywell and Aprilaire filtration components where integrated, and Guardsman insulation wrap for post-seal thermal protection. Mastic and mesh are commercial-grade, not hardware-store tape. The brands are on the truck, so there’s no delay. Call (361) 326-5060 for specifics on your system.
Constant cooling means cold ducts stay wet with condensation, which degrades inferior sealants within months. We use mastic rated for wet climates and verify full cure before closing the chase. The 365-Day Done Right Promise covers seal failure for a full year, including free return visits. In Sunrise’s climate, that written guarantee matters. Call (361) 326-5060.
