Fast, Reliable Duct Repair & Sealing Across Paradise
We’re Bellows Air Duct & Vent Co., and we’ve been driving out to Paradise since 1984 to fix ductwork that other companies walk away from. If you live in the 89119 ZIP, in one of those mid-rise apartment complexes off Twain Avenue or near the airport corridor, you know the drill: your AC runs nonstop from May through September, and somehow there’s still dust on every surface no matter how often you clean. That’s not a housekeeping problem. That’s leaking ductwork pulling in Mojave caliche and construction particulate from every unsealed joint.
We answer calls 24 hours a day, and most Paradise jobs are completed in a single visit. Our technicians are background-checked, uniformed, and carry the equipment to seal metal ducts, replace torn flex runs, and apply mastic sealant in tight crawlspaces and utility closets. Call (844) 685-6342 for a free estimate. We’ll show you exactly what’s wrong with a camera inspection before we lift a single tool.
Why Bellows Air Duct & Vent Co. Is Paradise’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in Paradise on showing up when we say we will and leaving systems that stay fixed. Our Duct Repair & Sealing in Paradise work is backed by our 90-Day Done Right Promise - if it’s not right, we return at no charge, no paperwork, no arguing. That’s been our standard for over 42 years.
Paradise customers call us because we’ve seen what desert heat and airport-adjacent dust do to 1970s and 1980s ductwork. We repaired and sealed the flex duct branches in a 1980s townhome off Twain Avenue, where unfiltered return-air intake had allowed crystalline silica dust to accumulate into a gray-brown cake, choking the system. We replaced the damaged flex with insulated duct, applied mastic sealant at all joints, and installed a new Aprilaire media filter to protect the system from future desert dust. That’s the kind of work we do.
Every job gets a camera inspection before and after. You see what we see. Our pricing is disclosed upfront before work begins - the number on the phone is the number on the invoice. No bait coupons, no changes at the door. And calls are answered by a live person, 24/7, not a voicemail tree.
Our Duct Repair & Sealing Services in Paradise
Mastic Sealant Application
In Paradise’s 89119 ZIP, aging apartment complexes built between 1970-1990 often share central ductwork that has never been sealed, and the airport’s construction dust adds a second particulate burden on top of Mojave caliche. We apply professional-grade mastic sealant to every joint, seam, and penetration point - not just the ones you can see. Mastic remains flexible under thermal expansion, which matters when your attic hits 140°F in July and metal ducts are contracting every night. We use Abatement Technologies prep systems to clean surfaces before application, so the sealant bonds properly and lasts. In 1970s casino-boom builds, we’ve found that improper mastic application on metal duct joints is the single most common cause of recurring air leaks under 115°F heat strain.
Flex Duct Repair
Flex duct in Paradise crawlspaces and utility chases deteriorates faster than almost anywhere else. The combination of constant airflow, attic heat cycling, and rodent activity in dense multi-unit housing means tears and collapsed runs are routine. We replace damaged sections with insulated flex duct rated for desert conditions, seal all connections with mastic and mechanical fasteners, and verify airflow balance before we leave. Flex duct repairs that ignore the double dust load from airport construction cause rapid re-clogging within a single cooling season - we see it every summer. We don’t just patch the tear; we trace the intake path and seal the return plenum so the new duct stays clean.
Metal Duct Repair
Original galvanized steel ductwork in Paradise’s older complexes develops rust at low points, separates at longitudinal seams, and whistles at joint gaps when static pressure builds. We patch corroded sections, re-seam separated runs, and reinforce hanger supports that have sagged under decades of vibration. Our metal duct repair includes pressure-testing the system after completion to verify we’ve eliminated the leaks causing that whistling noise. In 1970s Paradise complexes, this is often the only way to stop the noise and restore even airflow to every unit.
Duct Insulation & Air Leak Repair
Uninsulated or poorly insulated ductwork in Paradise attics bleeds cooled air into 130°F spaces before it ever reaches your vents. We install foil-faced fiberglass insulation on repaired and sealed runs, with vapor barriers facing the correct direction for our dry climate. Air leak repair targets the return side especially - that’s where unfiltered desert air gets sucked into the system, bypassing your filter entirely. Sealing only visible leaks while leaving return plenums unsealed allows caliche and silica to bypass filters and re-contaminate the system. We don’t do half a job.

Common Duct Repair & Sealing Problems We See in Paradise Homes
- Improper mastic application on metal duct joints in 1970s casino-boom builds, leading to recurring air leaks under 115°F heat strain. The original installers often used tape that degrades in attic heat, or applied mastic too thin to survive thermal cycling. We strip the old material, prep the surface, and apply sealant to the correct thickness.
- Flex duct repairs that ignore the double dust load from airport construction, causing rapid re-clogging within a single cooling season. Harry Reid International’s expansion has added construction particulate to the baseline Mojave caliche. If we don’t seal the intake path, your new flex duct is dirty again before fall.
- Sealing only visible leaks while leaving return plenums unsealed, allowing caliche and silica to bypass filters and re-contaminate the system. The return plenum is often the dirtiest, leakiest part of the system in Paradise’s multi-unit buildings. We inspect and seal it every time.
- Collapsed flex duct in tight crawlspaces of 1980s townhomes, choking airflow to second-floor units. These spaces are often too cramped for standard equipment. We carry compact tools specifically for Paradise’s dense housing stock.

FAQs - Duct Repair & Sealing in Paradise
Yes. Duct seams from the 1980s were typically sealed with foil tape or thin mastic that degrades after 40 years of thermal cycling, and leaks pull attic air into the system long before dust becomes visible at your vents. In Paradise’s climate, that means 115°F attic air mixing with your cooled supply air every summer, wasting energy and overworking your compressor. Call (844) 685-6342 for a camera inspection - estimates are free.
Yes, but only if the repair includes sealing the return plenum and intake path, not just the supply ducts. That gray-brown debris is crystalline silica and construction particulate from Harry Reid International’s expansion activity, combined with Mojave caliche, entering through unsealed return-air leaks. We see this exact pattern in 89119 apartment complexes. Without sealing the intake side, cleaning is temporary. Call (844) 685-6342 and we’ll show you the leak sources on camera.
Yes. We splice in insulated flex duct sections using mechanical collars and mastic sealant, matching the existing diameter and R-value, without disturbing intact runs. Most Paradise crawlspace repairs are completed in two to three hours. Call (844) 685-6342 for same-week scheduling.
Yes, if the whistling is caused by joint gaps or seam separation at static pressure points - the most common source in 1970s casino-boom construction. We pressure-test after repair to confirm. If the noise persists, it’s usually a damper or register issue, which we also diagnose. Call (844) 685-6342 for an exact diagnosis.
Yes, we carry Rotobrush agitation systems on every Paradise truck for cleaning and prep work before sealing, especially in flex duct with heavy particulate buildup. The brush system loosens debris so our Nikro HEPA vacuum extracts it completely. We don’t seal over contamination. Call (844) 685-6342 to schedule.
