We’ve been driving to Bedford homes for over four decades, and we know the town’s streets well enough to find a colonial off Great Road or a split-level near the Bedford VA without GPS. Our technicians are dispatched from our Dallas-Fort Worth office, but they live and work in the communities they serve. That matters when your attic ducts are leaking heated air into January cold and your system can’t keep the living room above 64°F. We’ll be there when we say, and we’ll show you exactly what’s wrong before we touch a tool.
Why Bellows Air Duct & Vent Co. Is Bedford’s Preferred Duct Repair & Sealing Company
Bedford homeowners don’t call us for flash. They call because their neighbor on Concord Road did, or their coworker at a Route 128 firm mentioned we fixed a 1970s attic trunk without pushing a full replacement. Our reputation here is built on showing up, doing the job right, and leaving without drama.
We answer the phone 24 hours a day with a live person, not a menu tree. Most Bedford calls reach a technician on the road within the hour. Our background-checked, uniformed crews carry the equipment to complete most repairs in one visit, including mastic sealant, metal tape, flex-duct replacement sections, and rigid insulation board for attic chases.
Our 90-Day Done Right Promise applies to every Bedford job. If the seal fails or the repair doesn’t hold, we return at no charge. No paperwork, no arguing. We’ve operated this way since 1984 because it’s the only way that keeps a customer for forty years.
We also honor a permanent 5% Senior and Veteran discount, and we offer $50 off any repair over $250. Our $89 Seasonal Tune-Up catches duct problems before they become expensive failures.
Our Duct Repair & Sealing Services in Bedford
Duct Sealing
Bedford’s Hanscom-era homes lose 20-30% of conditioned air through leaks before it reaches the rooms. We seal with mastic compound and professional metal tape, not the hardware-store foil tape that peels in attic heat. A typical duct sealing job in Bedford runs $280-$450 for a single system. We camera-inspect before and after so you see the difference.

Flex Duct Repair
The flex-duct branches connecting your registers to the main trunk were never designed for fifty years of Bedford heating cycles. We see collapsed liners, torn connections, and joints that have pulled completely free in crawlspaces and basements. Repair runs $180-$340 per branch; replacement with new insulated flex is $320-$480. We’ll tell you which makes sense after we look.

Metal Duct Repair
This is where Bedford’s housing stock creates problems no generic duct page can address. The 1960s-1980s colonials and split-levels built for Hanscom AFB and Route 128 contractors commonly have main duct trunks routed through uninsulated attic chases. Attic temperatures in Bedford exceed 130°F in summer. That repeated expansion and contraction pulls sheet-metal seams apart, sometimes gaping ¾ inch or more. Once open, those seams draw in decades of accumulated fiberglass batt debris and blown-in insulation directly into your supply air.
We re-seal with mastic, reinforce with metal tape, and insulate the chase to stop the thermal cycling that caused the failure. In a 1972 split-level on Cross Street, we found the original sheet-metal trunk in the attic had seam separations up to ¾ inch, sucking in fiberglass batts from the uninsulated chase. We re-sealed the entire trunk with mastic and applied metal tape to all joints, then insulated the chase to stop the thermal cycling that caused the failure. The homeowner’s energy bill dropped 18% the following heating season. Metal duct repair in Bedford typically runs $380-$650 depending on trunk length and access.

Duct Insulation
Uninsulated or degraded duct insulation is a second, hidden problem in Bedford’s attic runs. We install foil-faced rigid board or wrap with formaldehyde-free fiberglass, bringing attic ducts up to current energy code and stopping the heat loss that forces your furnace to run overtime through six-month heating seasons. Expect $450-$780 for full trunk insulation in a typical Bedford colonial.

Trusted Brands We Service in Bedford
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same brands serious HVAC contractors specify for commercial jobs. We stock mastic sealants, metal tapes, and flex-duct fittings sized for the older systems common in Bedford, so we’re not ordering parts and making you wait. That matters when your ducts are leaking in February and every day of delay costs you money on the heating bill.
Common Duct Repair & Sealing Problems We See in Bedford Homes
- Seam separation in attic trunks from 130°F summer heat cycling. Bedford’s uninsulated attic chases cook sheet-metal ducts July through August. The expansion and contraction works joints loose over decades, and once a gap opens, it pulls in insulation debris every time the blower runs. We see this in colonials off Great Road and split-levels near the Bedford Center regularly.
- Flex-duct joints at registers split apart from decades of heating cycles. The original flex branches in 1960s-1980s homes have hardened, cracked, or pulled free at the collar. Conditioned air leaks into crawlspaces and attics instead of reaching bedrooms. Homeowners notice cold spots first, then rising heating bills.
- Return-air grilles clogged with heavy spring pollen. Bedford’s dense tree canopy, oak and maple especially, produces pollen loads that overwhelm standard grille filters during the brief window when windows are open between heating and cooling seasons. Starved returns increase static pressure, which worsens leaks in already compromised ductwork.
- Interior liner deterioration in original flex duct. The fiberglass liner inside early flex duct breaks down after forty years, releasing particles into supply air and reducing duct diameter. We camera-inspect to assess whether repair or full replacement is the honest call.

FAQs - Duct Repair & Sealing in Bedford
Re-seal the trunk with mastic and metal tape, then insulate the attic chase to stop the thermal cycling that caused it. This is the most common repair we do in Bedford’s Hanscom-era homes, and it typically runs $380-$650. Full replacement is rarely necessary unless the metal is corroded through. Call (844) 685-6342 for a free inspection - we’ll show you camera footage of exactly what’s happening in your attic.
If the outer jacket is torn or the interior liner is shedding particles, replacement is the honest call; if only the connection collar has pulled free, repair suffices. We camera-inspect every flex duct before recommending anything. Most Bedford homes need some of each. A free second opinion on any written estimate guarantees you get the straight answer.
Yes. Bedford’s six-month heating season means every leak costs you daily from October through April. Our Cross Street customer saw an 18% drop after we sealed and insulated their attic trunk. Typical savings range 12-25% depending on leak severity. The work pays for itself over two to three heating seasons.
Upgrade to MERV 11 or 13 filters during pollen season, seal window frames and attic hatches, and keep returns clear of landscaping debris. We also inspect and seal return-air plenums where pollen infiltrates through gaps in the duct wall. Our $89 Seasonal Tune-Up includes filter sizing and return inspection.
Original sheet-metal trunk lines in Bedford’s Hanscom-era homes are almost always repairable. The metal itself lasts; it’s the seams and joints that fail from thermal cycling. We re-seal, reinforce, and insulate rather than replace unless we find rust-through or physical damage. Camera inspection tells the story in five minutes. Call (844) 685-6342 to schedule - estimates are free.
