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 Golden Glades
Duct sealing in Golden Glades typically runs $450 – $1,200 per system depending on access, duct material, and how many independent air handlers serve the home. Most jobs take a half day to a full day, and we schedule within a few days of your call. If your home has multiple zones, each system gets its own written scope and its own measured leakage documentation before we start. Call (361) 326-5060 for a free estimate with a price that won’t change at the door.
We know Golden Glades. Our crews dispatch from the Miami office and work this corridor regularly, from the low-rise blocks off NW 7th Avenue to the apartment clusters near the interchange. The 1960s – 80s concrete-block housing stock here, the year-round AC load, and the particulate that blows in from I-95 and the Palmetto Expressway all shape what goes wrong in these ducts and how we fix it. This isn’t generic suburban work. The humidity, the truck traffic, and the post-storm power outages create failure patterns a local crew recognizes on sight.
Why Hollis Air Duct Cleaning Is Golden Glades’s Preferred Duct Sealing Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Miami office dispatches crews to Golden Glades homes weekly. That repetition matters. A technician who sealed ducts in a 1972 block home off NW 135th Street last month knows what to expect in the next one: fiberglass duct board plenums that have absorbed decades of humidity, flex runs sagging in the attic, and added-zone systems that were never properly integrated into the original sealing scope.
Our customers in Golden Glades leave reviews that mention the same things: the technician arrived inside the window, explained the per-system pricing before touching anything, and left documentation they could actually read. We don’t compete on the lowest teaser price. We compete on The Garrison Standard: written price before work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise backed in writing. If the seal fails within a year, we come back and make it right at no charge, including a free second visit.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When you’re dealing with mold smell from stagnant post-storm air, you don’t wait until Monday.
Duct Repair in Golden Glades
Duct Repair in Golden Glades means fixing the physical damage that makes sealing impossible: collapsed flex duct in hot attics, separated seams in fiberglass duct board plenums, and boots pulled loose from drywall by decades of vibration. We see this most often after summer storm season, when attic access is limited and the damage isn’t visible from the living space. A typical duct repair in Golden Glades runs $280 – $650 per location depending on material and access.
When Repair Comes Before Sealing
Sealing a torn flex run is pointless. We inspect with a camera first, identify every break or collapse, and repair with matching materials before any mastic goes on. In Golden Glades homes with original 1960s – 80s duct board, we often find the plenum itself delaminating, which requires rebuild, not just tape.
Documentation You Can Verify
Every repair gets photographed before and after. You see what we saw. If a section of flex duct got replaced, you see the old material and the new routing. This matters in Golden Glades, where multiple systems in one house mean repairs happen in attics you never enter.
Air Duct Sealing in Golden Glades
Air Duct Sealing in Golden Glades addresses the conditioned air leaking into attics, wall cavities, and crawl spaces through gaps at plenums, boots, and seams. In this climate, every cubic foot of cooled air you lose costs you twice: once to generate it, once to dehumidify the replacement air your system pulls from outside. A typical air duct sealing job in Golden Glades runs $450 – $1,200 per system based on linear footage of duct, number of boots, and whether we need to remove and reseal existing failed tape.
Per-System Scoping, Not Per-House Flat Rates
Golden Glades homes often have two or three independent systems added over decades. Each has its own air handler, its own plenum, its own supply and return runs. We measure leakage on each separately with a duct blaster or pressure pan test, seal each to its own standard, and document each with before/after numbers. One flat price for the whole house would either overcharge you for a small system or under-scope a large one.
Mastic and Mesh for This Climate
We use water-based duct mastic reinforced with fiberglass mesh tape, applied to clean, dry surfaces. In Golden Glades, that means we check for active moisture intrusion first. Sealing over damp fiberglass duct board guarantees the tape lifts within a season. Our techs verify dryness with a moisture meter, especially after storm events when attic humidity spikes.
Trusted Brands We Service in Golden Glades
Our trucks carry sealing and repair materials from Nikro, Honeywell, and Abatement Technologies, plus filtration upgrades from Aprilaire when a sealed system needs better protection against the fine particulate that blows through the Golden Glades interchange. We stock local parts for fast turnaround on common Golden Glades configurations: 14-inch flex duct, fiberglass duct board plenums, and the boot adapters used in 1960s – 80s concrete-block construction. If your system needs a filtration upgrade after sealing, we size it to the actual airflow we measured, not guess from the nominal tonnage.
Common Duct Sealing Problems We See in Golden Glades Homes
- Moisture-compromised mastic from prior work. In Golden Glades, fiberglass duct board and flex duct hold humidity for days after summer storms. Mastic or tape applied over damp surfaces lifts within one cooling season, leaving the homeowner with a fresh invoice and the same leaks. We dry-test every surface before sealing.
- Added-zone systems skipped in whole-house scopes. Many Golden Glades homes started with one system and added a second or third zone later. A crew sealing only the main system’s plenum and boots leaves the added systems leaking, often the ones running the longest flex runs through the hottest attic space. We scope and document every independent air handler.
- Biological growth sealed behind new work. Post-storm power outages leave stagnant, humid air sitting in ducts for days. Sealing without first addressing active mold or mildew traps the contamination behind the new seal. The smell returns through registers within weeks. We inspect visually and with cameras before sealing.
- Storm-silt film coating duct interiors. The Golden Glades interchange area sees heavy truck traffic and road spray that introduces ultrafine particulate through outdoor intakes. This film reduces airflow and provides a substrate for mold. We agitate and extract before sealing so the new seal adheres to actual duct material, not grime.
Pricing for Duct Sealing in Golden Glades, FL
A typical single-system duct sealing in Golden Glades runs $450 – $750. Two-system homes range $800 – $1,100. Three-system homes, common in larger properties with added zones, run $1,050 – $1,400 total. These are whole-system prices, not per-vent teaser rates that balloon once the van is in your driveway.
What moves the number: linear footage of ductwork, number of boots and plenums, whether existing tape and mastic need complete removal, and whether we find moisture damage requiring repair before sealing. We give you one flat price per system, agreed in writing, before any work starts. No per-vent add-ons. No “while we’re here” upsells.

FAQs About Duct Sealing in Golden Glades
You pay per system, because each has its own measured leakage, its own plenum, and its own set of boots and runs to seal. A single-system scope would either miss the added zones entirely or average the cost in a way that overcharges you. We test and document each air handler separately, and you get independent before/after numbers for every one. Call (361) 326-5060 for a free estimate that counts your actual systems.
Storm events introduce extra silt through outdoor intakes and raise attic humidity enough to compromise existing seals. If your ducts show active moisture damage or biological growth, we need to address that before sealing, which adds scope. Your neighbor with a drier attic and cleaner duct interior gets a different job. We quote what we find, not a flat rate that ignores conditions. Call (361) 326-5060 for an inspection that reflects your actual duct state.
Yes, these are the materials we work with most often in Golden Glades. Fiberglass duct board requires mastic and mesh tape at all seams and corners; flex duct needs proper support and sealing at both ends. The key is surface preparation. We verify the fiberglass is dry and the flex isn’t collapsed or torn before sealing, because new mastic on damaged substrate fails fast in this humidity. Call (361) 326-5060 to schedule an inspection.
We measure static pressure and airflow at each air handler before and after sealing, and we photograph accessible seams and boots. You get a written report with those numbers and images, not a verbal “it’s done.” In Golden Glades, where multiple systems and long flex runs hide most of the ductwork, this documentation is the only proof you have. If the numbers don’t improve, we don’t call it finished. Call (361) 326-5060 for a job that includes real verification.
Clean first, then seal. In Golden Glades, the combination of year-round humidity and fine road particulate means ducts often carry a film of silt and organic material that prevents proper mastic adhesion. Sealing over that film traps contamination and guarantees early failure. We agitate and extract, verify clean dry surfaces, then seal. The 365-Day Done Right Promise covers the sealing work, but it requires proper prep to honor. Call (361) 326-5060 to schedule both steps in the right sequence.
