Why Bellows Air Duct & Vent Co. Is Dearborn Heights’s Preferred Duct Repair & Sealing Company
We’ve earned our reputation in Dearborn Heights one job at a time. Homeowners here talk to each other - at the hardware store on Warren Avenue, at the church picnic, over the fence - and word gets around when a company shows up late, changes the price, or leaves a mess. We’ve never had to advertise heavily in Dearborn Heights because our customers call us back and tell their neighbors.
Our response time to Dearborn Heights is typically same-day or next-day, and emergency calls are answered by a live person 24 hours a day - not a voicemail tree, not an app. We know the local housing stock: the ranches with 7-foot basements near Ford Field Park, the Cape Cods off Beech Daly, the split-levels near John F. Kennedy Jr. Park. That familiarity means we bring the right tools the first time, including the low-profile Rotobrush attachments that fit where standard equipment won’t.
Every technician is background-checked and uniformed, and every job starts with a camera inspection and ends with one. You’ll see the corrosion, the crushed runs, the deteriorating liner - before we touch anything and after we’re done.

Our Duct Repair & Sealing Services in Dearborn Heights
Metal Duct Repair
The galvanized steel trunk lines in Dearborn Heights’s 1950s-60s ranches weren’t built to last forever. We’ve replaced corroded takeoff collars in basements near Annapolis, patched crushed main trunks under living rooms in the Inkster Road corridor, and rebuilt furnace plenums that had rusted through from decades of sump pump failures. Metal duct repair in Dearborn Heights typically runs $280-$550 for localized work, or $600-$1,200 if we’re replacing a full main trunk in a low-clearance basement where every cut has to be made at an awkward angle. Our crew carries sheet-metal brakes, crimpers, and Guardsman-grade aluminum tape for permanent seams - not the hardware-store foil that peels off in three seasons.
Duct Sealing
Original Dearborn Heights ductwork leaks. It’s not a question of if, but where and how much. The mastic sealant we apply with professional-grade pumps fills gaps that foil tape can’t touch, especially around irregular takeoff angles and old fiberglass liner edges. On a typical Dearborn Heights ranch, full duct sealing runs $350-$680 depending on linear footage and access difficulty. We seal every joint, every seam, every penetration - then verify with a camera that the mastic cured properly and no gaps were missed. The result is conditioned air that reaches your rooms instead of your basement or crawlspace.
Flex Duct Repair
Many Dearborn Heights homeowners had flex duct added during furnace replacements in the 1990s and 2000s, often routed through attics or crawlspaces that weren’t designed for it. That flex gets crushed by storage boxes, chewed by rodents, or simply sags and kinks over time. Flex duct repair in Dearborn Heights is usually $220-$420 per run, or $180-$320 if we’re replacing a short damaged section with new insulated flex properly supported every four feet. We use Nikro equipment to verify airflow after repair, ensuring the new flex isn’t just connected but actually delivering the CFM your rooms need.
Duct Insulation
Original fiberglass duct liner in Dearborn Heights homes is often past its useful life - crumbling, moisture-stained, or contaminated from basement flooding. We remove deteriorated liner and replace it with modern foil-faced insulation or external duct wrap, depending on clearance and configuration. Duct insulation work in Dearborn Heights ranges from $320 for localized replacement to $850 for full trunk-line re-insulation in a low-clearance basement. Every job includes a post-work camera inspection so you can see the difference.

Trusted Brands We Service in Dearborn Heights
We stock parts and specify equipment from the brands that professional HVAC contractors trust: Rotobrush for our compact spinning brush systems that fit Dearborn Heights’s tight basement clearances, Honeywell for zone dampers and control accessories, and Aprilaire for media air cleaners and fresh-air ventilators that integrate with repaired duct systems. We don’t order parts from a catalog and make you wait a week. Our trucks carry common fittings, sealants, and repair materials so most Dearborn Heights jobs are completed in a single visit - not two or three.
Common Duct Repair & Sealing Problems We See in Dearborn Heights Homes
- Deteriorating fiberglass duct liner shedding particles. The fibrous glass liner in 1950s-70s systems breaks down after decades of airflow and temperature cycling. Homeowners seal visible gaps with hardware-store tape but miss the liner erosion that’s pumping microscopic fibers into every room. We camera-inspect the full run to locate deterioration that surface repairs can’t address.
- Low-clearance basements blocking proper cleaning and repair. Many Dearborn Heights ranchers have main trunk ducts with less than 12 inches of clearance above basement floor joists. Standard spinning brushes and vacuum attachments can’t reach past the first few feet. Our Rotobrush compact heads and right-angle attachments are specifically sized for these spaces - the difference between a real repair and a register-level vacuum job.
- Moisture damage from basement flooding wicking into duct systems. Dearborn Heights’s flat topography and aging combined-sewer infrastructure make spring backups a recurring reality. When water reaches the furnace plenum area, it soaks fiberglass insulation and corrodes metal takeoff collars. Painting over stains doesn’t fix porous, mold-seeded duct runs - we remove wet material and seal with mastic to prevent recurrence.
- Crushed or disconnected flex duct from amateur repairs. On a home near Ford Field Park, the 60-year-old sheet-metal trunk was crushed by a previous owner’s misguided repair attempt, leaving a 4-inch gap that leaked conditioned air into the crawlspace. Our crew used Rotobrush spinning brushes and mastic sealant to restore the run, sealing all leaks with Guardsman-grade aluminum tape for a permanent fix.

FAQs - Duct Repair & Sealing in Dearborn Heights
Most flex duct added during 1990s-2000s furnace replacements can be repaired if the damage is localized - a crushed section, a disconnected collar, rodent damage to a short run. We typically repair rather than replace when the existing flex is less than 15 years old, properly routed, and not contaminated with moisture or mold. Call (844) 685-6342 and we’ll camera-inspect to give you a straight answer on repair versus replacement.
Mastic sealant is significantly better than foil tape for original galvanized steel in Dearborn Heights homes. The irregular surfaces, corroded edges, and deteriorating fiberglass liner on 1950s-60s ductwork don’t provide the smooth, clean substrate that foil tape needs to adhere permanently. We apply mastic with professional pumps, brush it into every seam and penetration, and back it with Guardsman-grade aluminum tape at high-stress joints. The combination lasts decades where foil tape fails in three to five years.
Wet or moisture-stained fiberglass liner must be removed, not sealed over. Sealing traps moisture against metal surfaces, accelerates corrosion, and creates an enclosed mold reservoir that distributes spores through your supply air. We remove damaged liner, treat the metal surface, and replace it with modern foil-faced insulation or external wrap depending on your basement clearance. In Dearborn Heights’s flood-prone areas near the combined-sewer zones, we also evaluate sump pump and drainage improvements to prevent recurrence.
We rebuild the damaged section with custom-fabricated galvanized steel or, in severe clearance constraints, transition to properly supported flex duct with rigid connectors. In Dearborn Heights’s sub-12-inch clearances, we use compact crimping tools and pre-formed angle pieces that fit where standard equipment won’t. Every repair is sealed with mastic and verified with a camera before we close access. The key is bringing tools sized for your space - which is why out-of-town crews often damage more than they fix in these homes.
There is rarely a benefit to full replacement with flex duct in Dearborn Heights’s postwar homes. Original sheet-metal trunk lines, properly repaired and sealed, outperform flex in durability, airflow, and rodent resistance. Flex is appropriate for short branch runs with good support and protection, but as a main trunk replacement it sags, creates turbulence, and typically reduces system efficiency. We recommend metal repair and sealing unless the original trunk is structurally compromised beyond restoration - and we’ll show you the camera footage so you can see why.
