Why Bellows Air Duct & Vent Co. of New York Is Somerset’s Preferred Duct Repair & Sealing Company
We’ve worked in Somerset long enough to know which split-levels on Hamilton Street have the tight 12-inch crawl spaces, which 1980s colonials near Easton Avenue need degreaser pre-treatment before we’ll even touch the return grilles, and why flex duct in the 08875 section fails differently than in neighboring Piscataway. Our technicians are background-checked and uniformed, and they answer to a live person at our office who picks up 24 hours a day. We’ve built our reputation in Somerset on one principle: the price we quote on the phone is the price on the invoice, backed by our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork. No arguing.
Our Somerset customers tend to be longtime homeowners, not flippers. They want the repair done once, done properly, and never thought about again. That’s who we built this company for.
Our Duct Repair & Sealing Services in Somerset
Mastic Sealant
Somerset’s 1970s-1990s sheet-metal trunk lines were originally sealed with a thin bead of mastic that has dried and cracked over 30-50 years of thermal cycling. We apply mastic in a 1/8-inch bed, reinforced with fiberglass mesh tape at seams and joints, then brush a second coat to full saturation. In Somerset’s humid summers and cold winters, undersized mastic applications crack within a single season. We don’t shortcut this. A typical mastic resealing job for a Somerset colonial runs $320-$480.
Flex Duct Repair
The flex-duct branches in Somerset’s raised-ranch and split-level homes were installed with minimal slack and no accommodation for Central New Jersey’s humidity-driven expansion and contraction. Joints gape. Insulation sags. We replace damaged sections with insulated R-8 flex duct, install proper support straps every 4 feet, and leave enough slack for seasonal movement. In a 1985 split-level on Hamilton Street, our crew found a metal trunk line with a split seam at a tight 90-degree bend and flex duct joints gaping from seasonal expansion. We sealed the metal seam with mastic and fiberglass tape, replaced the damaged flex section with insulated R-8 duct, and degreased the return grille with a citrus solvent before finalizing the repair. Flex duct repair in Somerset typically runs $240-$420.
Metal Duct Repair
Somerset’s original galvanized steel trunk lines corrode at seams, split at stress points, and separate at collars. We cut out damaged sections, fabricate replacement pieces on-site, and seal with mastic and fiberglass tape, not duct tape. Duct tape fails in Somerset’s humidity. Metal repair jobs range from $280 for a localized seam fix to $650 for trunk line section replacement.
Duct Insulation
Uninsulated or degraded duct insulation in Somerset’s crawl spaces and attics creates condensation problems six months of the year. We install R-8 fiberglass duct wrap with vapor barrier, sealed at all seams, to stop sweating and thermal loss. Full insulation wrap for a typical Somerset split-level system runs $480-$720.

Common Duct Repair & Sealing Problems We See in Somerset Homes
- Undersized mastic applications that crack within one season, re-opening gaps in aging metal duct seams. Somerset’s temperature swings between summer humidity and winter cold stress every seal. Thin mastic can’t survive it.
- Flex duct repairs that ignore the seasonal expansion-contraction cycle, leading to re-gapping within months. We see this from cut-rate competitors who pull flex taut and call it done. It fails by spring.
- Skipping degreaser pre-treatment on kitchen returns, leaving turmeric-oil residue that re-clogs fresh seals. Standard residential cleaning protocols don’t account for Somerset’s cooking intensity. We pre-treat with citrus solvent before agitation.
- Condensation damage in uninsulated crawl space ducts. Somerset’s summer dewpoints regularly push duct surfaces below the condensation point. Uninsulated metal sweats, rusts, and breeds mold.

FAQs - Duct Repair & Sealing in Somerset
Central New Jersey’s humidity swings cause flex duct to expand in summer and contract in winter, pulling joints apart if they were installed without slack or proper support. We replace damaged sections with properly supported R-8 flex and leave expansion loops at turns. Call (833) 348-8789 for an inspection - estimates are free.
Yes. The aerosolized oil and spice particulates in Somerset’s high-heat cooking environments bond to sheet-metal walls and act as a glue for dust, preventing proper mastic adhesion and clogging downstream filters. We degrease kitchen returns with citrus solvent before sealing. Call (833) 348-8789 - we’ll show you the camera footage.
Not necessarily. Often the supports have failed or the original installer didn’t leave expansion slack. We camera-inspect first. If the flex is intact, we re-support and reseal. If it’s degraded, we replace the damaged section. A typical partial repair runs $240-$420 in Somerset. Call (833) 348-8789 for a free estimate.
We use mastic brushes on extension poles and pre-cut fiberglass tape strips applied by hand in tight quarters. It’s slower work, which is why some contractors skip it or use duct tape. We don’t. Crawl space sealing in Somerset’s split-levels typically adds 1-2 hours to the job. Call (833) 348-8789 to discuss your specific access.
Sealing leaks helps contain cooking odors within the conditioned space, but persistent turmeric smell usually requires full system cleaning with degreaser pre-treatment, not just sealing. We often recommend both for Somerset kitchens. Call (833) 348-8789 - we’ll design the right approach for your home.
