Fast, Reliable Duct Sealing Across Paradise
Duct sealing in Paradise typically runs $450 – $1,400 for a whole-home job, depending on how much of the original ductwork can be saved and how many leaks our techs find once we get a camera inside the runs. Most Paradise homes built between the 1960s and 1980s were sealed with foil tape that has long since dried out and peeled away, which means the real fix usually involves mastic, UL-listed tape, or both, applied at every joint and connector we can access. If you live near Twain Avenue, Swenson Street, or anywhere off Maryland Parkway and your AC runs constantly without cooling the house, you’re likely losing conditioned air into the attic before it ever reaches a vent. Call us at (775) 383-5847 and we’ll tell you what a sealing job would cost for your specific home before any work starts.
We work all over Paradise, from the older single-family neighborhoods near Paradise Elementary School to the apartment complexes clustered around Tropicana Avenue and the Strip corridor. Our Duct Sealing crew knows what original 1960s metal duct and 1980s flex duct look like when they’ve spent decades in Mojave Desert air, and we price the work in writing before the first tool comes off the truck. You won’t get a ballpark that doubles once a technician is on site.
Why Hollis Air Duct Henderson Is Paradise’s Preferred Duct Sealing Company
Paradise homeowners call us because we show up when we said we would, price the job in writing before touching anything, and back every sealing repair for a full year under the 365-Day Done Right Promise. That means if a seam we sealed fails within 365 days, we come back at no charge and make it right, no negotiation and no second invoice.
Our techs are background-checked and uniformed, and they arrive inside the quoted window, not somewhere in a four-hour span that eats your whole afternoon. When you book a duct sealing job in Paradise, you’ll know who’s walking through your door before they get there. The trucks carry Rotobrush rotary brush systems, Nikro negative-air machines, and sealing materials including UL-listed tapes and water-based mastic, the same class of gear commercial crews use on larger buildings.
Every job is run to The Garrison Code: arrive inside the window, price in writing, complete the work by the book, and leave the site cleaner than we found it. Roy Castellanos, who leads Hollis Air Duct Henderson, set that standard because too many Paradise residents have been burned by crews that left a mess, ghosted a callback, or found a “new problem” that tripled the quote. We don’t run that game. Dispatch and scheduling for Paradise jobs are coordinated from the brand’s Las Vegas office, but the crews serving Paradise are local, and they know these homes.

Duct Repair in Paradise
Duct repair in Paradise usually means fixing what decades of heat, dust, and poor original installation have done to the runs feeding your bedrooms and living spaces. We camera-inspect before we quote, because the ductwork in this city hides problems you won’t see from the vent cover. A typical duct repair job in Paradise runs $250 – $700 per repair section, depending on whether we’re replacing a crushed flex run, re-hanging sagging duct, or sealing separated metal seams in an attic that’s been baking since the Johnson administration.
Collapsed and Crushed Flex Duct
Homes built in the 1970s and 1980s around Paradise Valley and south of Flamingo Road often have original flex duct that has collapsed under years of fine sand accumulation. Once a flex run kinks or tears at the connector, the air you’re paying to cool is dumping into the attic. We replace the damaged section, re-hang it with proper support straps, and seal both ends with mastic and UL-listed tape so it doesn’t sag again.
Separated Metal Seams
Original galvanized duct in 1960s-era Paradise homes has been through thousands of hot-cold cycles, and the seams where sections meet eventually work loose or rust through. When that happens, you’re losing 20 to 30 percent of your conditioned air into unconditioned space. Repair means pulling the nearby insulation, cleaning the joint down to bare metal, and sealing with a water-based mastic that bonds even in Paradise’s dry heat.
Air Duct Sealing in Paradise
Air duct sealing in Paradise is the repair that actually stops the leaks, not just the symptom. When our techs seal ductwork here, they’re working against decades of accumulated dust, sometimes grease, and the constant static pressure of a system that runs nearly year-round. A whole-home air duct sealing job in Paradise typically runs $450 – $1,400, with the final number depending on how many runs we can reach from the attic access and how badly the original joints have failed.
Sealant That Bonds to Paradise’s Duct Interiors
The biggest mistake we see from other companies is slapping tape over dust. Sealant won’t hold if the surface underneath is coated in fine alkaline powder, and in Paradise that powder is everywhere. Our techs clean each joint down to solid material before applying mastic and UL-listed tape. It takes longer, but it’s the difference between a seal that lasts one summer and a seal that holds for a decade.
Verification After the Work Is Done
We don’t hand you a bill and tell you to trust us. After sealing, our techs check static pressure and airflow at the vents to confirm the system is actually moving more air to the rooms you live in. If the numbers don’t improve, we haven’t finished. That verification is part of every air duct sealing job we do in Paradise, and it’s part of what the 365-Day Done Right Promise covers in writing.
Trusted Brands We Service in Paradise
We seal ductwork connected to every major HVAC brand you’ll find in Paradise homes, including systems covered by our Paradise Lennox service, and we carry a stock of common connectors, flex runs, and sealing materials on the truck so we’re not leaving mid-job to chase a part across town. When a Paradise homeowner calls about a leaking system, our techs work with Rotobrush rotary brush systems to prep the interior surface, Nikro negative-air machines to keep disturbed dust out of your living space, and sealing products that meet UL listings for fire and smoke safety. Filtration brands like Honeywell and Aprilaire may be part of the conversation if your system’s filter housing needs attention while we’re in there, and we’ll explain in plain terms what each piece does for your air before we touch anything.

AfterCommon Duct Sealing Problems We See in Paradise Homes
- Greasy film on duct interiors near the Strip. Units within a half-mile of Las Vegas Boulevard often show a gray, greasy residue inside return ducts – a mix of casino exhaust and airborne cooking oils from 24-hour restaurant workers. That film has to come off before any sealant can bond, which is a step a lot of companies skip.
- Rusted or separated seams on original 1960s – 1980s metal duct. Decades of condensate cycles in Paradise’s hot-dry-then-cold-aired homes have caused seams to corrode and pull apart. The brittle alkaline dust that fills the gaps makes standard sealant fail within a season if the surface isn’t prepped properly.
- Sagging flex duct in older multifamily buildings. Fine sand weighs down unsupported flex runs in apartments along Tropicana and Flamingo Road corridors, and once a run sags, it tears at the connector. Re-hanging and sealing both ends is the only repair that lasts.
- Leaking return plenums on 1960s split-levels. Homes near Paradise Park and the neighborhoods north of the airport often have return plenums built with drywall and minimal sealing. Those leak unconditioned attic air into your return stream, which means you’re cooling an attic you don’t even live in.
Pricing for Duct Sealing in Paradise, NV
Here’s what you can expect to pay for Duct Sealing in Paradise, based on the jobs we do most often.

A whole-home sealing job across all accessible supply and return runs typically falls between $450 and $1,400. What pushes the number up: multiple collapsed sections, heavy grease or dust buildup that requires extra prep, and tight attic access that slows the work down.

FAQs About Duct Sealing in Paradise
Homes within about half a mile of the Strip pick up a gray, greasy film inside return ducts that comes from casino exhaust and airborne cooking oils from 24-hour restaurant workers. Sealant won’t bond to grease, so if a company doesn’t clean and prep the interior surface before sealing, the tape and mastic peel off within months. We clean every joint down to solid material before applying anything, which is the only way to get a seal that lasts in this specific part of Paradise. Call (775) 383-5847 for an honest assessment of your duct condition.
Yes, in most cases the original galvanized metal is still structurally sound and only the seams and connections have failed. We can clean the joints, seal them with mastic and UL-listed tape, and restore most of the airflow you’ve been losing without ripping out and replacing every section. Replacement only becomes necessary when the metal itself is rusted through or crushed. A camera inspection tells us what you’re actually working with, and we’ll show you the footage before we quote.
No. If the flex duct is crushed or torn, sealing alone won’t restore airflow, because the run itself has collapsed. In older Paradise multifamily buildings, fine sand weighs down unsupported flex runs until they sag and tear at the connectors. The fix is to replace the damaged section, re-hang it with proper support, and seal both ends. Sealing is the finishing step, not the whole repair. Call (775) 383-5847 and we’ll camera-inspect your ducts to see what’s actually going on before quoting anything.
Paradise’s AC systems run almost continuously from May through October, and often well into the shoulder months, which means the ducts are under constant static pressure and any weak seam leaks constantly. The dry Mojave air also makes the dust and debris inside old ducts brittle, so cleaning before sealing is more involved than in more humid climates. We prep every joint knowing the system will be running hot within days, so the sealant and tape have to hold up under immediate, sustained pressure and extreme attic heat.
We check. After sealing, our techs measure static pressure before and after the job, and we verify airflow at the vents. On a 1970s single-family home near Twain Avenue, we found the original flex duct had collapsed in two places and the return plenum was coated in a sticky gray paste. We camera-inspected both supply and return runs, replaced the crushed sections, and sealed every joint, then verified with negative pressure that static dropped from 0.9 to 0.5 inches. If the numbers don’t improve, we haven’t finished, and the 365-Day Done Right Promise means we’d come back at no charge if anything regressed.
