Why Bellows Air Duct & Vent Co. Is Hudson’s Preferred Duct Repair & Sealing Company
Hudson homeowners don’t call us for flash. They call because their neighbor did, or because they got tired of a contractor who showed up late, found “extra problems,” and handed them a bill that looked nothing like the phone quote. We’ve built our reputation in Worcester County on doing the opposite.
Our Duct Repair & Sealing team has worked in Hudson’s 01749 zip code since the 1980s. We’ve sealed ducts in the Victorian multi-families near the Assabet River, replaced flex duct in postwar Capes off Cox Street, and tracked down air leaks in ranch basements near the Stow town line. Every job gets a camera inspection before we start and another when we’re done. You see what we see. No claims, just footage.
Calls to our office are answered by a live person, 24 hours a day. Not a voicemail tree. Not an app. A real person who can get a technician to Hudson today if that’s what you need. Most repairs are completed in a single visit. Our 90-Day Done Right Promise is stamped on every invoice: if it’s not right, we make it right, no paperwork, no arguing. That’s been our policy since 1984.
Our Duct Repair & Sealing Services in Hudson
Duct Sealing
Sealing is where most Hudson homes need to start. The retrofitted forced-air systems in this town’s older housing stock were installed with duct tape that has turned to dust behind your walls. We seal metal trunk joints with professional-grade mastic, the thick paste that hardens into a permanent bond. In a Victorian multi-family near the Assabet River on Broad Street, we found a return-air plenum lined with mold due to ground-level humidity. We sealed all metal trunk joints with mastic, replaced two lengths of deteriorating flex duct, and installed a Honeywell UV air purifier to prevent regrowth, completing the job in a single trip as promised. Mastic sealing in Hudson typically runs $280-$520 for an average single-family home.
Flex Duct Repair
Flex duct is common in Hudson’s 1950s and 60s retrofits, and it’s usually failing where it connects to metal trunks or where it has been crushed in tight crawlspaces. We replace deteriorated flex with new insulated duct, properly supported and sealed. The undersized sheet-metal trunks common in retrofitted mill housing cause poor airflow that forces furnaces to run longer, worsening static pressure and accelerating duct joint failures. Flex duct replacement in Hudson ranges from $180 for a single run to $640 for multiple lengths in a multi-family.
Metal Duct Repair
When a sheet-metal trunk is rusted through, disconnected at a seam, or punctured, we cut out the damaged section and install new galvanized ductwork, sealed with mastic and mechanical fasteners. This is heavy-duty work, especially in the tight mechanical closets and crawlspaces of Hudson’s older homes. We don’t patch with tape and hope. We repair so it lasts.
Duct Insulation
Uninsulated or poorly insulated ducts in Hudson’s unconditioned basements and crawlspaces lose heated air in winter and cooled air in summer. That means your furnace works harder during those sustained sub-freezing stretches Worcester County is known for, and your AC strains against the humidity the Assabet River valley holds in July. We install proper insulation where it’s missing or degraded, typically $340-$580 for a standard Hudson home.

Trusted Brands We Service in Hudson
We stock parts and equipment from Rotobrush, Nikro, and Abatement Technologies on every truck that rolls toward Hudson. These are the same brands serious HVAC contractors specify, not hardware-store substitutes. For air quality concerns tied to Hudson’s river-adjacent humidity, we also install Honeywell and Aprilaire UV purifiers and dehumidification components. Because we carry inventory rather than ordering as-needed, most Hudson repairs don’t wait on parts. We fix it today.
Common Duct Repair & Sealing Problems We See in Hudson Homes
- Failed duct-tape seals in 1950s retrofits. Duct-tape seals on 1950s retrofits have completely degraded behind walls, leading to massive air leakage and dust infiltration that can’t be fixed without accessing tight crawlspaces. We find this in nearly every pre-1960 multi-family we inspect in Hudson.
- Undersized trunks causing static pressure damage. The original sheet-metal trunks in mill-era housing were never designed for modern airflow demands. Poor airflow forces furnaces to run longer, worsening static pressure and accelerating duct joint failures until the system is leaking more air than it’s delivering.
- Mold in river-adjacent return plenums. River-adjacent properties experience persistent mold in return plenums due to elevated humidity, which standard duct sealants won’t address without integrated microbial treatment. Technicians working homes near the Assabet River floodplain frequently find this condition, far less common on the drier, higher-elevation lots of neighboring Berlin or Stow.
- Crushed or disconnected flex duct in crawlspaces. Hudson’s older homes have minimal clearances. Flex duct gets compressed by storage, damaged by rodents, or pulled loose at connections. We replace and properly support it so airflow is restored.
Pricing for Duct Repair & Sealing in Hudson, MA
We’re upfront about numbers because nobody likes a surprise on the bill. A typical duct sealing job in Hudson runs $280-$520 for a single-family home, $420-$780 for a multi-family with more trunk line to address. Flex duct repair or replacement is $180-$640 depending on length and accessibility. Metal duct repair starts around $340 for a section replacement and can reach $850 for extensive trunk rebuilding in a tight crawlspace. Duct insulation runs $340-$580.
What moves you within these ranges? Accessibility matters most. A full basement with headroom costs less than a dirt crawlspace under a 1900s triple-decker.

FAQs - Duct Repair & Sealing in Hudson
Yes, in most cases we access and seal leaks through existing basement or crawlspace openings without cutting wall plaster. We use remote camera inspection to locate the worst leakage points, then apply mastic sealant to accessible joints and replace damaged flex duct from below. Call (844) 685-6342 for a free inspection - estimates are free.
We seal ductwork in any structure with a forced-air system, including detached workshops, converted barns, and outbuildings. If your workshop has a furnace or heat pump connected to ductwork, we can inspect, seal, and repair it. The same upfront pricing applies. Call (844) 685-6342 to schedule.
That smell is almost always mold or microbial growth in your return-air plenum, caused by the elevated ground-level humidity in Hudson’s river-adjacent neighborhoods. Standard duct cleaning alone won’t solve it. We treat the affected components with antimicrobial agents, seal with mastic to prevent reinfiltration of moist air, and can install a Honeywell UV purifier for ongoing prevention. Call (844) 685-6342 - estimates are free.
Most duct sealing jobs on Hudson’s triple-deckers take four to six hours, depending on crawlspace accessibility and whether flex duct replacement is needed. We complete the work in a single visit as promised. Call (844) 685-6342 to book - we’ll be there when we say.
Not always. If the flex duct is intact but poorly connected, we can reattach and seal it with mastic. If the inner liner is torn, the insulation is waterlogged, or the duct is crushed, replacement is the only lasting fix. We camera-inspect every run and show you the condition before recommending anything. Call (844) 685-6342 for an honest assessment - estimates are free.
