Why Bellows Air Duct & Vent Co. of New York Is Upper Montclair’s Preferred Duct Repair & Sealing Company
Upper Montclair homeowners don’t call us once. They call us for their house, then their neighbor’s house, then their grown children’s houses. That’s how we’ve built our reputation here - one honest job at a time, no coupons, no bait pricing.
Our Upper Montclair customers leave reviews that mention the same things: we showed up when we said we would, we explained the problem without talking down to anyone, and the price on the phone matched the price on the invoice. We answer our own phones 24 hours a day - a live person, not a menu tree. Most repairs are finished in a single visit by technicians who’ve passed background checks and wear our uniform.
We know the local terrain. Upper Montclair sits on the elevated eastern slope of the First Watchung Mountain ridge, which pulls in more humidity than lower-lying towns like Brookdale or Cedar Grove. That moisture load matters when we’re sealing ducts in your unheated attic or treating mold inside a plaster-walled chase. We factor it into every recommendation we make.
Our Duct Repair & Sealing Services in Upper Montclair
Duct Sealing with Mastic Sealant
The original duct tape or mastic applied during your home’s 1950s or 60s coal-to-gas conversion has dried and cracked by now. Sixty years is a long time for any adhesive. We remove the old failing material, clean the joint surfaces, and apply fresh mastic sealant rated for the temperature swings your Upper Montclair system sees through all four seasons. On a recent job near Edgemont Park, we sealed 14 separate joints in a single Victorian’s retrofit duct network and dropped the homeowner’s air leakage by 34 percent. Camera-verified, before and after.
Flex Duct Repair
Flex duct doesn’t last forever, especially when it was installed in tight attic spaces never designed for it. On a Colonial Revival on South Mountain Avenue, we found a flex duct branch feeding the second floor had collapsed from age and was disconnected at the plenum. We replaced it with insulated flex duct, sealed all joints with mastic, and installed an Aprilaire filter to capture legacy coal soot still circulating. The homeowner’s upstairs bedrooms finally got warm.
Metal Duct Repair
Original galvanized metal ductwork in Upper Montclair’s pre-war homes corrodes from the inside out when decades of accumulated soot hold moisture against the steel. We patch salvageable sections with matching metal and sealant, or replace corroded runs entirely. Working inside narrow plaster-walled chases takes patience and the right flexible equipment - we’ve invested in both. Our Rotobrush and Nikro tools navigate spaces that rigid commercial gear simply won’t fit.
Duct Insulation
Uninsulated attic duct runs in Upper Montclair sweat all summer. The First Watchung ridge’s elevated humidity loads condense on cold metal and flex surfaces, creating the perfect conditions for mold growth inside your system. We wrap accessible runs with professional-grade insulation from Abatement Technologies and seal every penetration point. In winter, that same insulation keeps your heated air from bleeding into an unconditioned attic before it reaches your bedroom.

Trusted Brands We Service in Upper Montclair
We stock parts and materials from Honeywell, Aprilaire, Abatement Technologies, and Guardsman - the same brands serious HVAC contractors specify for their own homes. For Upper Montclair’s older housing stock, parts availability matters. A failed damper or corroded plenum connection in a 1930s Colonial Revival isn’t always a standard size. We carry the adapters, transition fittings, and specialized sealants that keep your repair moving instead of waiting on a warehouse shipment. Most jobs finish in one visit because we arrive prepared for what these houses actually contain.
Common Duct Repair & Sealing Problems We See in Upper Montclair Homes
- Original mastic or duct tape on retrofitted joints dries and cracks after 60+ years, causing major air leaks in hard-to-access chases. We find this in nearly every pre-WWII home we inspect in Upper Montclair. The material simply wasn’t designed to outlast two generations.
- Uninsulated attic duct runs in pre-war homes sweat in Upper Montclair’s humid climate, leading to mold growth that requires sealing and insulation repair. The First Watchung ridge’s weather patterns make this worse than in neighboring towns at lower elevation.
- Legacy coal-to-gas conversion debris, like soot and coal dust, clogs registers and reduces airflow, often needing metal duct repair or replacement of corroded sections. Many Upper Montclair homes, converted from coal to forced-air in the 1950s-60s, still have original plenum connections in basement mechanical rooms caked with decades of soot and debris that were never cleaned after the conversion.
- Collapsed flex duct branches in second-floor feeds cut off entire zones of the house. The original installers in the 1960s often used the lightest-grade flex available, routed through impossibly tight spaces. It fails predictably after 50+ years of thermal cycling.

Yes, we repair and replace metal ductwork inside narrow plaster chases throughout Upper Montclair’s 07043 ZIP code. Our flexible equipment from Rotobrush and Nikro navigates spaces rigid commercial tools cannot access. Most repairs run $420-$650 depending on accessibility and corrosion extent. We’ll camera-inspect the chase first so you know what you’re dealing with before any work begins.
We install professional-grade insulation on accessible attic duct runs, which is essential in Upper Montclair due to the First Watchung ridge’s elevated humidity. Uninsulated metal and flex duct sweat in summer, promoting mold growth and bleeding conditioned air into unused space. Typical attic insulation work runs $380-$580. The energy savings usually recover the cost within two heating seasons.
We can seal accessible joints inside chases through existing access panels or register openings, but we won’t promise what we can’t verify. Our camera inspection shows which leaks are reachable and which require minimal access. When we do need to open a wall, we work with small, precise cuts that a plaster contractor can patch cleanly. We’ll show you the camera footage and explain every option before you decide.
In Upper Montclair’s pre-WWII housing stock, we recommend inspection every 10-15 years and resealing when joints show cracking or air leakage exceeds 15 percent. The original 1950s-60s conversion materials simply don’t last forever. Our mastic sealant work carries the 90-Day Done Right Promise - if a joint we sealed fails within 90 days, we return at no charge with no paperwork required. For a current assessment of your system, call (833) 348-8789 and we’ll camera-inspect at no cost.
