Why Bellows Air Duct & Vent Co. Is Irvington’s Preferred Duct Repair & Sealing Company
We’ve been serving Irvington and the surrounding Newark metro corridor since 1984. That’s over 42 years of crawling through basement trunk lines in converted two-families, sealing retrofitted ducts in floor cavities, and explaining to homeowners on Hillside Avenue why their 1920s row house has airflow problems no suburban HVAC contractor could diagnose.
Our technicians are background-checked, uniformed, and trained on the specific failure modes of Irvington’s housing: crumbled mid-century insulation, shared duct trunks serving multiple rental units, and flex duct crushed behind alley-loaded townhomes. Every job gets a camera inspection before and after, so you see the gap, the seal, and the result. Our 90-Day Done Right Promise means if the seal doesn’t hold, we come back. No paperwork. No arguing.

Our Duct Repair & Sealing Services in Irvington
Duct Sealing
Most Irvington homes lose 20 to 30 percent of conditioned air through leaks in duct joints, splices, and trunk line connections. In a converted two-family on Elmwood Avenue or Nye Avenue, that means the furnace works harder, the bills climb, and rooms stay cold. We seal every accessible joint with mastic sealant and foil tape, then pressure-test the system to verify the fix. Our camera records before and after. You see the leak, you see the seal, you see the airflow improvement.

Mastic Sealant Application
Mastic is the only sealant we trust for Irvington’s older metal ductwork. Caulk dries and cracks. Tape alone peels. Mastic stays flexible, fills gaps up to a quarter-inch, and bonds to galvanized steel, fiberglass, and flex duct sleeves. In Irvington’s humid summers, that flexibility matters. We apply it with brushes and spatulas in basement trunk lines, around register boots, and at splices inside wall cavities where retrofitted ducts pass between units. It’s messy work. We wear coveralls so you don’t have to worry about yours.

Flex Duct Repair
Flex duct is common in Irvington’s retrofitted systems, run through closets, basement ceilings, and floor cavities never designed for forced air. It crushes, it kinks, it tears at splices. On Lyons Avenue, we sealed a leaking flex duct splice tucked inside a closet of a converted two-family where the original duct trunk served both units. The joint had a 3-inch gap dumping conditioned air into the wall cavity, and we used mastic sealant and foil tape from our Rotobrush kit to restore airflow and stop attic mold from being drawn into the bedroom registers. Most flex duct repairs in Irvington run $180 to $340 and are done in under two hours.

Metal Duct Repair
Galvanized steel trunk lines in Irvington’s older homes corrode at seams, separate at joints, and get punctured by decades of basement work. We patch small holes with metal-backed tape and mastic, replace rusted sections with new snap-lock pipe, and rehang sagging lines with proper strap supports. In shared basements serving multiple units, we coordinate access with tenants and landlords. One honest price. Shown before we start.

Duct Insulation Replacement
Crumbled mid-century duct insulation in basement trunk lines sheds fibers and debris into the airstream. We remove the old material, clean the metal, and install new foil-faced insulation with sealed seams. In Irvington’s converted two-families, this is often the first step before sealing can begin. Insulation replacement for a typical basement trunk line runs $400 to $650.

Common Duct Repair & Sealing Problems We See in Irvington Homes
- Crumbled mid-century duct insulation in basement trunk lines sheds fibers and debris into the airstream, requiring full insulation removal and mastic sealing before the duct can be resealed. We see this in nearly every pre-1960 two-family we enter in Irvington.
- Improperly spliced, alley-loaded flex duct runs behind townhomes are crushed by trash bins or snagged during landscaping, creating hard-to-find air leaks that waste energy and pull in dusty crawlspace air. These repairs often require crawling through tight rear accessways common on the blocks off Springfield Avenue.
- Landlords defer sealing of leaky return-side ducts in basement ceilings, causing the furnace to pull soot-laden air from old boiler rooms and crawl spaces, recirculating particulates from decades of urban dust and diesel exhaust. We document this with our camera and show tenants and owners exactly what’s entering their air supply.
- Shared duct trunks serving multiple rental units develop leaks at partition penetrations where walls were added or modified, dumping conditioned air into interstitial spaces and creating pressure imbalances that draw in unfiltered basement air.

FAQs - Duct Repair & Sealing in Irvington
Duct repairs in Irvington’s older two-families take longer because the ductwork was retrofitted decades after construction into spaces never designed for it, often running through floor cavities, closets, and basement ceilings with tight clearances and non-standard connections. Many systems have never been professionally maintained, so we encounter crumbled insulation, debris accumulation, and improvised splices that must be addressed before sealing can begin. A job that takes two hours in a purpose-built ranch can take four in a 1920s Irvington two-family. Call (844) 685-6342 for a free estimate and we’ll explain what your specific system needs.
Yes, we regularly seal shared duct trunks in Irvington’s converted two-families and row homes, though we may need access to both units or coordinate with your landlord if you rent. We seal leaks at partition penetrations, rehang sagging sections, and install balancing dampers where possible to improve airflow to both sides. The work is documented with camera footage, and our 90-Day Done Right Promise covers the entire trunk regardless of how many units it serves. Call (844) 685-6342 to schedule an inspection.
We use flexible borescope cameras to inspect ducts through existing registers, basement cleanouts, and small access panels before cutting any wall or ceiling. In Irvington’s cramped basements, our technicians are trained to work in spaces as tight as 18 inches, and we carry compact tools specifically for these conditions. If wall access is necessary, we cut minimal openings, document the leak, seal it, and patch the access point. You’ll see the camera footage before and after. Call (844) 685-6342 for a free inspection.
Yes, crushed or kinked flex duct behind alley-loaded townhomes is one of the most common repairs we do in Irvington, and most are fixed in a single visit. We replace the damaged section with new insulated flex duct, support it properly to prevent future crushing, and seal all joints with mastic and foil tape. If the original run was poorly routed, we’ll reroute it to avoid the pinch point. Typical cost is $180 to $340. Call (844) 685-6342 for an exact quote.
Yes, duct sealing typically reduces heating and cooling costs by 20 to 30 percent in Irvington’s older homes, where leaks in shared trunk lines and retrofitted duct runs waste conditioned air into basements and wall cavities. In a converted two-family with deferred maintenance, the savings can be substantial enough to pay back the sealing cost within two heating seasons. We pressure-test before and after to measure the improvement. Call (844) 685-6342 for a free estimate and we’ll show you where your money is going.
