Why Bellows Air Duct & Vent Co. Is Montclair’s Preferred Duct Repair & Sealing Company
We’ve been in business since 1984 - 42 years of showing up when we say we will and standing behind the work. In Montclair, that reputation travels by word of mouth through neighborhoods like Upper Montclair, Brookdale, and along Bloomfield Avenue where homeowners talk to each other about who actually fixed the problem.
Our technicians are background-checked, uniformed, and carry the equipment to finish most jobs in a single visit. Calls come through to a live person 24 hours a day, not a voicemail tree. Before we touch a tool, we show you the camera inspection of your ductwork and we show you the price. Same number on the phone, same number on the invoice. Our 90-Day Done Right Promise covers every job in writing - if it’s not right, we make it right, no paperwork, no arguing.
We know the local building patterns here. Montclair’s residential core was built largely between the 1960s and 1980s, which means attic-run flex duct and fiberglass duct board that’s now 40 to 60 years old. We’ve replaced and sealed enough of it to know where the failures happen before we even climb the ladder.
Our Duct Repair & Sealing Services in Montclair
Duct Sealing
Leaky ducts waste 20 to 30 percent of your heated and cooled air, and in Montclair’s climate that’s real money from May through October when the AC runs hard. We seal metal joints with professional-grade mastic sealant - not tape, which dries and fails - and we pressure-test the system to verify results. Homes near the 60/10 interchange need this more urgently; the diesel particulate load in your return air accelerates seal degradation, so what held ten years ago may be failing now.
Flex Duct Repair
The flex duct in Montclair’s ranch homes and split-levels has often sagged, torn at the collars, or been chewed by rodents in the attic. We replace damaged runs with new insulated flex duct, properly supported every four feet so it doesn’t sag again. The field vignette from our crew: we recently sealed a 1970s ranch on Vernon Avenue near the 10 freeway, where the return plenum had a thick gray-black dust cake and the original flex duct had sagged and torn at the joints. We replaced the damaged flex with new insulated duct, applied mastic sealant to all metal connections, and wrapped the attic supply runs, restoring balanced airflow throughout the house.
Metal Duct Repair
Older Montclair homes with galvanized steel ductwork develop rust at the seams and separations where the original sealant has hardened. We cut out corroded sections, fabricate replacement pieces, and seal with mastic rated for metal-to-metal joints. If your system bangs or whistles when the blower starts, that’s often a metal duct joint that’s worked loose after decades of thermal cycling.
Duct Insulation
Uninsulated or degraded duct insulation in Montclair’s hot attic spaces means you’re cooling the attic all summer. We wrap supply runs with foil-faced fiberglass insulation or replace the duct entirely with pre-insulated flex where the old material has collapsed. This matters especially in Montclair’s inland climate, where attic temperatures can hit 140 degrees in August and every degree of lost cooling shows up on your PSE&G bill.

Common Duct Repair & Sealing Problems We See in Montclair Homes
- Mastic seals fail prematurely from diesel particulate buildup. Homes along the south and east sides near the 60/10 interchange have return-air plenums coated with a gray-black layer from the Ontario-Chino logistics corridor. This particulate is abrasive and chemically active; it breaks down mastic seals faster than in cleaner air, causing leaks at joints that were tight five years ago.
- Original fiberglass duct board deteriorates after 40-60 years. Montclair’s tract-built ranches from the 1960s through 1980s often still have the original fiberglass duct board. It sheds fibers, loses its structural rigidity, and the foil facing delaminates. We replace it with modern flex or sheet metal, sealed properly.
- Santa Ana wind events drive dust and allergens into duct systems. When those hot, dry winds blow from the high desert, they push fine particles through every infiltration gap in your home. Ducts with even small leaks pull this contamination directly into your airflow, and the abrasive dust accelerates wear on duct interiors.
- Attic flex duct sags and tears at supports. The original plastic straps in Montclair’s attic systems have often degraded in the heat. Duct sags, kinks, or pulls free at the collar. We re-support with metal strap and proper hanging methods that won’t repeat the problem.

FAQs - Duct Repair & Sealing in Montclair
It’s diesel ultra-fine particulate from the Ontario-Chino logistics corridor, one of the densest freight concentrations in the country. The 60/10 interchange funnels continuous truck traffic, and those particles penetrate home envelopes and settle in return-air plenums. We see this routinely on homes along Montclair’s south and east sides. The layer is not ordinary household dust - it’s oily, abrasive, and it degrades duct seals faster than typical particulate. Call (844) 685-6342 and we’ll inspect your system and show you exactly what’s in there.
Every 5 to 7 years for inspection, with sealing as needed. Montclair’s combination of diesel particulate, Santa Ana dust events, and heavy summer AC cycling accelerates seal degradation compared to coastal Southern California. If your home is within a mile of the 60/10 interchange or you run AC more than six months a year, inspect at 5 years. Call (844) 685-6342 to schedule - estimates are free.
Water-based mastic sealant applied with a brush or caulking gun to all metal joints, plus mechanical fastening of flex duct collars. Tape alone fails in Montclair’s attic heat. For the 1960s-1980s ranch homes that dominate Montclair’s housing stock, we also re-support sagging flex duct and replace degraded fiberglass duct board rather than trying to seal material that’s already disintegrating. Call (844) 685-6342 and we’ll assess what your specific system needs.
Yes, significantly. Sealed ducts don’t pull unfiltered air from your attic or wall cavities when the blower runs. During Santa Ana events, when outdoor particulate spikes and infiltration pressure increases, a sealed system only circulates the air that passes through your filter. We pressure-test after sealing to verify you’re not drawing in attic air. Call (844) 685-6342 for an estimate - we’ll show you the before and after with our camera.
Look for weak airflow from specific vents, rooms that won’t heat or cool evenly, or a musty smell when the system runs. In Montclair’s conditions, the inner liner of flex duct often tears at the joints or the insulation wrapper collapses, both of which you can’t see without a camera. We inspect every system before quoting - you’ll see exactly what we’re seeing. Call (844) 685-6342 to book a camera inspection; if repair is needed, the $89 seasonal tune-up or assessment fee is credited toward the work.
