AfterFast, Reliable Duct Sealing Across West Park
Duct sealing in West Park, FL typically costs $450 – $1,200 for a whole-home seal on mid-century ranch homes, with most jobs completed in a single visit. We’re Hollis Air Duct Cleaning, and we’ve been crawling the attics of West Park’s concrete-block ranches since 2004 - we also offer West Park Dryer Vent Cleaning for homes in the area. Our dispatch office in Miami coordinates crews who serve West Park directly, and we know the difference between a routine duct cleaning call and the sealing work these older homes actually need. Call (361) 326-5060 for a free estimate, or read on to understand why your 1960s ranch might be leaking half its conditioned air into the attic.
Why Hollis Air Duct Cleaning Is West Park’s Preferred Duct Sealing Company
We’re not new to Broward County. Our Duct Sealing team has handled the specific headache of West Park’s retrofit attic ductwork for two decades. Homeowners here deal with a housing stock that doesn’t exist anywhere else in South Florida, at least not in this concentration: fully built-out, slab-on-grade, mid-century ranches with abandoned under-slab supplies and decades-old flex overhead.
That matters because a technician who treats your home like a standard suburban build will clean your ducts and leave the real problem untouched. We don’t do that. Our written price covers the inspection, the seal, and the verification, and it doesn’t move once we’re inside. Our 365-Day Done Right Promise means if a sealed joint fails within a year, we come back at no charge, including a free second visit. Background-checked, uniformed technicians arrive inside the quoted window, price in writing before touching anything, and leave the site clean. That’s The Garrison Standard, and it’s how we operate in West Park on every job.
Duct Insulation in West Park
Duct Insulation in West Park is usually a repair, not an upgrade. The flex duct retrofitted into your vented attic decades ago has an R-value so degraded that it sweats through every summer, and that condensation breeds the mildew you smell when the blower kicks on. We reinsulate with Guardsman-approved foil-facing materials after sealing, because a sealed duct that still sweats will fail again.
When Attic Sweat Destroys the Liner
West Park’s dew points sit in the mid-70s for months. That moisture hits the cool surface of uninsulated or poorly insulated flex and doesn’t stop. The inner liner delaminates, the fiberglass sags, and suddenly you’ve got a 12-inch supply run pouring $0.14-per-kWh cooled air into a 140-degree attic. We strip the damaged wrap, seal the underlying joint with mastic, then reinsulate to R-8 or better.
Matching Insulation to Sealed Joints
Insulating over a leak is pointless. Our sequence is inspect, seal, then insulate, with a camera pass to verify. The homeowner sees the before and after. No guesswork.
HVAC Duct Sealing in West Park
HVAC Duct Sealing in West Park addresses the disconnected, crushed, and rodent-damaged flex runs that are standard in 1950s – 1970s ranches with attic retrofits. We use negative-air HEPA equipment during the process so disturbed particulate doesn’t enter your living space, and we verify seal integrity with pressure testing.
Abandoned Slab Stubs and Mismatched Transitions
Here’s what we find constantly. The original under-slab supply was abandoned years ago. The attic retrofit tied into the old slab stub with a transition that was never meant to last. It’s unsealed, uninsulated, and leaking. We cut back to solid duct, install a proper collar, seal with mastic, and support the run so it doesn’t sag off the truss.
Pressure Testing After the Seal
A sealed system should hold. We measure static pressure before and after, and we show the homeowner the numbers. If the post-seal pressure doesn’t improve, we keep looking until we find the leak. That’s The Garrison Code: do it by the book, verify it, explain it.
Trusted Brands We Service in West Park
We stock parts and materials from Rotobrush, Nikro, and Guardsman for West Park jobs, which means no waiting on a Miami warehouse run for standard seals, collars, or foil-facing insulation. Our rotary brush systems handle the source removal before we seal, and our negative-air machines keep the work zone contained. For filtration and finishing, we source Honeywell and Aprilaire products when the job calls for upgraded media downstream of the seal. Fast turnaround matters in a climate where every day of leaking ductwork is money burned.
Common Duct Sealing Problems We See in West Park Homes
- Flex duct sweating and delaminating in vented attics. West Park’s 9 – 10 month cooling season means attic flex never gets a break. The inner liner turns black with mildew, the adhesive fails, and joints peel apart while the homeowner wonders why the electric bill climbed $80.
- Rodent nesting behind knee walls in low-slope roofs. These ranches don’t have steep pitches. Squirrels and rats get in, chew through flex, and displace insulation. We find shredded duct and acorn caches regularly on SW 56th Avenue and surrounding blocks.
- Disconnected wyes on attic retrofit runs. The original installer draped flex over trusses and called it done. Gravity, heat, and vibration do the rest. A wye 12 feet from the air handler separates, and the back bedroom gets nothing.
- Leaky transitions where attic retrofits meet abandoned slab stubs. This is nearly universal in West Park’s 1950s – 70s stock. The slab duct is gone but the boot remains, and the retrofit connection was never sealed to modern standards.
Pricing for Duct Sealing in West Park, FL
A typical duct sealing job in West Park runs $450 – $1,200 for a whole-home seal on a single-story ranch, depending on how many runs need attention and whether we find rodent damage requiring section replacement. Partial seals on two or three problem runs start around $280. Full replacement of degraded flex with new sealed ductwork, plus reinsulation, can reach $1,800 – $2,400 on larger homes with extensive attic retrofit systems.
What moves the number: accessibility (tight attics take longer), extent of rodent damage, whether the original slab stubs need capping, and how many transitions require rebuilding.

FAQs About Duct Sealing in West Park
You likely need both, but sealing is the fix for the comfort problem. Duct cleaning removes the debris; sealing fixes why the debris accumulated and why rooms won’t hold temperature. In a 1965 West Park ranch, the attic retrofit flex is probably leaking at multiple joints. We clean first, then seal, then verify. Call (361) 326-5060 for an exact quote, estimates are free.
The cleaning removed the dirt but not the leak. In West Park ranches, the back bedroom supply often runs through the hottest part of the attic, draped over trusses with a disconnected wye or crushed sag point. We camera the run, find the separation, and seal it. That back bedroom finally gets the airflow the system was designed to deliver.
Yes, and that’s most of what we do in West Park. The abandoned slab stub gets capped properly, the attic retrofit gets supported and sealed at every joint, and transitions get rebuilt with mastic and mechanical fasteners. We can’t access the slab duct, but we can make the attic system perform.
It helps if the smell comes from mildew growing on sweating, leaking duct surfaces. Sealing stops the conditioned air loss, which reduces the temperature differential that causes condensation. We typically pair sealing with reinsulation using Guardsman-approved materials to eliminate the sweat surface entirely. If mold is inside the duct liner itself, we may recommend section replacement.
Chewed flex with exposed fiberglass is past sealing, it needs section replacement. But rodent damage often starts at a joint they used for nesting access, and the surrounding seal may be intact enough to save. We inspect with a camera, mark what needs replacement versus what can be sealed, and write the price for both before starting. Call (361) 326-5060.
