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 Sunny Isles Beach
Duct sealing in Sunny Isles Beach typically runs $450 – $1,200 per unit depending on access, chase condition, and whether the work follows a Sunny Isles Beach Dryer Vent Cleaning. Most jobs are scheduled within a few days and require coordination with your building’s engineering office and condo association for elevator access and certificate of insurance.
We’re the Duct Sealing crew that works inside Sunny Isles Beach’s oceanfront towers week in and week out. Our dispatch and scheduling are coordinated from our Miami office, and our technicians serve Sunny Isles Beach locally. We know the Collins Avenue buildings, the Intracoastal towers, and the specific access protocols each association requires. If your unit’s pulling humid, salty air through a disconnected chase or your property manager needs post-work documentation before clearing re-occupancy, we handle the COI, the elevator scheduling, and the job itself. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Sunny Isles Beach’s Preferred Duct Sealing Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. We operate under The Garrison Standard, which means written prices before any work starts, arrival inside the quoted window, and a 365-Day Done Right Promise on every job. If the seal fails within a year, we come back and make it right at no charge, including a free second visit.
Our technicians are background-checked and uniformed. You know who’s walking into your unit before they arrive. Our 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.
We carry the equipment that matters for tower work: Rotobrush rotary brush systems for mechanical closet access, Nikro negative-air machines for contained cleaning, and sealing products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use, not hardware-store gear. And we explain what each one does for your specific chase configuration before we start.
Roy Castellanos leads this operation, and our Sunny Isles Beach customers get the same discipline we apply everywhere: price it in writing, do it by the book, leave the site clean.
Duct Repair in Sunny Isles Beach
Duct Repair in Sunny Isles Beach means fixing the mechanical failures that develop inside high-rise condominium units where in-unit air handlers connect to vertical duct chases through slab penetrations. The repair is almost always cabinet- and shaft-sealing work, not the flex-duct rewrap you’d find in a mainland attic. Typical Duct Repair in this market runs $350 – $850 depending on whether we’re reattaching a separated collar, replacing crushed chase sections, or rebuilding a plenum connection that salt air and vibration have loosened over decades.
Chase Penetration and Plenum Rebuilds
The worst leaks sit where your air handler cabinet meets the vertical chase through the concrete slab. Old foil tape dries and fails. Mastic cracks from decades of vibration. We remove the failed material, inspect with a camera, and rebuild the seal with mastic and reinforcing mesh rated for the humidity and salt exposure these closets see. The work is documented for your property manager if required.
Post-Leak Disconnection Repair
After a building plumbing or roof leak, moisture and salt air accelerate sealant failure. Collars separate. Duct liners sag. We find these during cleaning, show you the camera footage, and quote the repair before touching tools. No surprises at the door.
Air Duct Sealing in Sunny Isles Beach
Air Duct Sealing in Sunny Isles Beach is the preventive and corrective work that stops conditioned air from escaping into your building’s interstitial spaces and stops unconditioned, humid, salt-laden air from being drawn into your return. Because almost every Sunny Isles Beach residence is a high-rise condominium with its own in-unit air handler and slab-penetrating vertical duct chase, duct sealing here is cabinet- and shaft-sealing work done unit-by-unit inside a shared mechanical system – not the attic-and-crawlspace flex-duct rewrap that defines the same trade on the mainland. Air Duct Sealing in this market typically costs $450 – $1,200 per unit, with the higher end covering full chase sealing after a cleaning has exposed multiple leak points.
Mastic-and-Mesh Shaft Sealing
We seal the shaft penetration, the plenum connections, and the blower cabinet seams with duct mastic and fiberglass mesh. This outlasts foil tape by years, especially in the constant humidity and salt exposure of oceanfront towers. The seal is flexible, waterproof, and rated for the temperature cycling your system sees.
Supply and Return Rebalancing
After sealing, we measure static pressure and airflow at each register. A sealed system moves air differently than a leaky one. We adjust dampers and verify that your bedroom on the east side of the unit gets the same delivery as your living room facing Collins Avenue. Balancing is included in our sealing price, not tacked on later.
Trusted Brands We Service in Sunny Isles Beach
We carry sealing and filtration products from Honeywell, Aprilaire, and Abatement Technologies on every truck serving Sunny Isles Beach. These aren’t special-order items that delay your job. Our Miami warehouse stocks mastic, mesh, collar kits, and replacement plenum sections sized for the in-unit air handlers common in local towers, from older Carrier and Trane cabinets to newer Lennox and Goodman configurations. If your building requires specific materials for COI compliance, we source to spec and document accordingly. Fast turnaround matters in a market where property managers often need units cleared for re-occupancy on tight timelines.
Common Duct Sealing Problems We See in Sunny Isles Beach Homes
- Failed foil tape and dried mastic at the air handler plenum and duct-chase penetrations. The worst leaks sit in a tight mechanical closet no mainland attic job ever sees, and the repair usually surfaces during a cleaning, not before. Your technician runs a camera, finds the separation, and shows you the footage before quoting.
- Crushed or disconnected vertical chase runs after a building plumbing or roof leak. Moisture and salt air eat the sealant. The cabinet vibrates loose enough to separate the collar. We see this in 1960s and 1970s towers along Collins Avenue especially, where original materials have decades of exposure.
- Sealing the visible register boots while leaving the shaft penetration and blower cabinet open. Some crews do this. Humid salt-laden air keeps being drawn into the return. The mold odor returns within weeks. We seal from the cabinet outward, not just what you can see from the living room.
- Post-hurricane musty duct syndrome requiring documented cleaning and sealing before re-occupancy. After a hurricane or building-wide water intrusion, ducts in oceanfront towers can take on musty mold odors within days because the AC never stops running in the subtropical humidity. Property managers often require duct cleaning documentation before clearing a unit. We provide that documentation, and we seal the source so the problem doesn’t repeat.
Pricing for Duct Sealing in Sunny Isles Beach, FL
Duct sealing in Sunny Isles Beach runs $450 – $1,200 for a typical condominium unit. Duct repair, when needed separately, runs $350 – $850. What moves you within that range: the number of leak points the camera inspection reveals, whether we need to disassemble cabinetry or dropped ceiling to access the chase, and whether the work follows a full cleaning or stands alone.
We do not quote per-vent teaser prices that balloon once we’re inside. We give one flat price per system, agreed in writing before any work starts. The price does not move at the door. Estimates are free. Before-and-after photos of your own ducts are included. If your property manager needs COI, access coordination, or post-work documentation, we handle that at no extra charge.

FAQs About Duct Sealing in Sunny Isles Beach
We don’t touch the building’s central plant. Each condominium unit in Sunny Isles Beach has its own in-unit air handler, so we seal only your cabinet and vertical chase. We coordinate elevator access and COI with your building engineer, work inside your unit, and never interrupt other residents’ systems. Call (361) 326-5060 to schedule around your building’s access windows.
Sealing is usually part of the fix, but not the whole fix. We clean first, camera-inspect to find where moisture entered, then seal the penetration or collar separation that let humid air and mold spores in. Without sealing the source, the odor returns. We document the work for your property manager if re-occupancy clearance is required. Call (361) 326-5060 for a free estimate.
We remove failed foil tape entirely. It doesn’t seal anymore; it’s decorative at best. We clean the joint, apply mastic and reinforcing mesh, and rebuild the connection properly. The new seal outlasts the original by years, even in salt-air humidity. Call (361) 326-5060 to see what condition your joints are in.
We can seal without cleaning if the ducts are already clean and accessible. In practice, most Sunny Isles Beach units need cleaning first because the camera can’t see through buildup, and the leaks surface during that inspection. We quote both options after seeing your system. Call (361) 326-5060 and we’ll tell you which applies.
Yes. Salt-laden air accelerates corrosion on metal collars and dries out mastic faster than inland climates. We use sealing products rated for marine environments, and we inspect for salt corrosion on hardware that mainland crews rarely see. Your Intracoastal location makes proper sealing more important, not less. Call (361) 326-5060 for an inspection.
