We’ve been driving to Dearborn since 1984, back when these brick bungalows and small ranches were already twenty years old. Now they’re pushing seventy, and the original sheet-metal ductwork is showing it. We’re familiar with the narrow basement runs in East Dearborn, the asbestos-wrapped trunk lines in pre-1960 homes, and the particular corrosion pattern that industrial particulates cause near the Rouge River corridor. That local knowledge changes what we bring on the truck and how we approach the repair.
Why Bellows Air Duct & Vent Co. Is Dearborn’s Preferred Duct Repair & Sealing Company
Our reputation in Dearborn was built on showing up when we say and standing behind the work. The 90-Day Done Right Promise is stamped on every job - if it’s not right, we make it right, no paperwork, no arguing. Homeowners in the 48128 and 48120 ZIPs have told us that’s why they call back and why they refer their neighbors.
Calls to our office are answered by a live person, 24/7 - not a voicemail system, not an app. When a Dearborn caller needs same-day service because their furnace is cycling non-stop and the house won’t hold temperature, we can typically have a background-checked, uniformed technician on the road within hours. Most repairs are completed in a single visit.
We know the local housing stock because we’ve worked inside it for decades. The compact bungalows near Michigan Avenue, the ranches south of Ford Road, the dense blocks east of Greenfield - each has its own duct configuration, its own access challenges, and its own contamination profile. That matters when we’re pricing the job honestly upfront and choosing the right materials to fix it permanently.
Our Duct Repair & Sealing Services in Dearborn
Duct Sealing
Leaky duct joints can waste 20-30% of your heated or cooled air before it reaches the rooms. In Dearborn’s older homes, we see this constantly - original sheet-metal seams that were never properly sealed, now aggravated by decades of thermal cycling and, in the industrial corridor, accelerated corrosion from ferrous particulates. Our duct sealing service uses professional-grade mastic sealant and metal-backed tape to close gaps permanently, not the hardware-store foil tape that peels in Michigan humidity. We camera-inspect before and after, so you see the difference. A typical duct sealing job in Dearborn runs $280-$480 for a single system.
Metal Duct Repair
This is where Dearborn’s housing stock and industrial environment converge into a real problem. The original 1950s sheet-metal trunk lines in homes near the Ford Dearborn Truck Plant - especially in the 48120 ZIP - often rust through at the joints after years of metallic dust and humidity exposure. We replace damaged sections with 24-gauge galvanized steel, seal with mastic, and insulate to prevent condensation from starting the cycle again. Metal duct repair in Dearborn typically costs $350-$650 depending on linear feet and access. In a 48120 bungalow near the Ford complex, we tackled exactly this: the original trunk lines had rusted through at the joints, corroded by years of metallic dust and humidity. We replaced the damaged sections, sealed with mastic, and insulated the run. The homeowner noted the dark, metallic-smelling debris we extracted - a telltale sign of the industrial air intake that Dearborn techs recognize immediately and that suburban crews five miles west rarely encounter.
Flex Duct Repair
Some 1960s Dearborn ranches, particularly in the 48124 and 48128 areas, used flex duct in crawlspaces and attic drops where rigid metal wouldn’t fit. Flex duct crushes, tears, and separates at collars over time. We repair or replace damaged flex runs with properly sized, insulated flex or convert to rigid where access allows. Flex duct repair in Dearborn generally runs $180-$340 per run. The tight crawlspaces in these homes make access tricky, but our technicians carry the right equipment to work in confined spaces without cutting corners on the seal.
Duct Insulation
Uninsulated or deteriorated duct insulation in Dearborn’s climate is a year-round problem. In winter, heated air loses temperature traveling through cold basement runs. In summer, humid attic air condenses on cool duct surfaces, feeding mold and biofilm - especially in homes near the Rouge River floodplain where basement humidity runs high. We install new fiberglass duct wrap or replace degraded insulation on existing runs. Duct insulation in Dearborn typically costs $2.50-$4.50 per linear foot. For a typical bungalow with 40-60 feet of trunk line, that’s $400-$850. We use Abatement Technologies and Aprilaire materials specified for residential HVAC applications.

Trusted Brands We Service in Dearborn
We stock parts and specify materials from Rotobrush, Abatement Technologies, and Aprilaire - the same brands serious HVAC contractors use, not generic hardware-store substitutes. For Dearborn homeowners, that means faster turnaround because we’re not ordering parts from a catalog while your system sits open. When we’re working on a metal duct repair in a 48120 home or sealing joints in a 48128 ranch, we have the right mastic, the proper gauge steel, and the correct insulation on the truck. No return trips for materials, no delays. Our technicians are trained on the specific application of these products in older residential systems like the ones that dominate Dearborn’s housing stock.
Common Duct Repair & Sealing Problems We See in Dearborn Homes
- Rust-through at duct joints from industrial particulate corrosion. Homes in the 48120 corridor near the Ford plant and Rouge River pull in fine ferrous dust and carbon soot that settles in ductwork, accelerates corrosion at joints, and combines with humidity to eat through sheet metal faster than in purely residential suburbs.
- Asbestos-wrapped trunk line delamination in pre-1960s bungalows. Many Dearborn homes built in the 1940s and 1950s have cloth-wrapped or tape-wrapped asbestos insulation on original trunk lines. We seal around these areas without disturbing fibers, using containment and proper technique - never tearing into wrapped material.
- Undersized narrow duct runs trapping debris and impeding access. East Dearborn’s dense blocks of small ranches and bungalows often have 6-inch or smaller branch runs that were adequate for 1950s heating loads but now restrict airflow and make thorough sealing difficult with standard equipment.
- Basement humidity infiltration feeding mold in low-slung trunk lines. Homes near the Rouge River floodplain in 48120 and adjacent ZIPs deal with chronic basement dampness. Moisture enters through foundation gaps and condenses on cool duct surfaces, creating biofilm that degrades seals and reduces indoor air quality.

FAQs - Duct Repair & Sealing in Dearborn
Yes, in most cases we can seal and repair original sheet-metal ducts without full replacement. We use mastic sealant and metal-backed tape at joints, replace isolated rusted sections with matching 24-gauge galvanized steel, and camera-verify the seal. Full replacement is only necessary when corrosion has compromised multiple trunk sections or when the original design is fundamentally undersized for modern heating and cooling loads. Call (844) 685-6342 for a free inspection - we’ll show you exactly what needs work and what doesn’t.
It’s common in the 48120 corridor due to ambient industrial particulates, but it’s not something to ignore. The dark, metallic-smelling debris our technicians extract from ducts near the Ford Dearborn Truck Plant is a distinct contamination signature - fine ferrous dust and carbon soot drawn in through return air pathways, accelerated by the area’s humidity. This debris corrodes metal, degrades seals, and circulates into your living space. We clean and seal against it, and we can recommend filtration upgrades. Call (844) 685-6342 - estimates are free.
We work around asbestos-wrapped ductwork using containment and non-disturbance techniques, but we do not tear into, remove, or abate asbestos insulation - that requires licensed abatement. For sealing, we access joints from the unwrapped side, use extendable applicators for mastic, and seal collars without disturbing the wrap. If the wrap is delaminating or damaged, we’ll refer you to a certified abatement contractor before we proceed. We handle this situation regularly in Dearborn’s pre-1960 housing stock and know the proper protocol. Call (844) 685-6342 to discuss your specific configuration.
Yes, if your attic ducts are uninsulated or the existing insulation is degraded, sealing without insulating leaves significant efficiency on the table. In East Dearborn’s 1960s ranches, we often find attic drops with thin or missing insulation that lets heated air cool in winter and causes condensation in summer. Sealing stops air loss; insulation stops thermal loss. Doing both together typically pays back in 2-3 heating seasons given Michigan’s temperature swings. We price insulation by the linear foot and can bundle it with sealing for a single visit. Call (844) 685-6342 for an exact quote.
Yes, we seal and repair flex duct in tight crawlspaces - it’s a common challenge in Dearborn’s 1960s ranches where builders used flex for attic drops and under-floor runs. We repair separated collars, replace crushed sections, and seal connections with proper clamps and mastic. The tight access means we use compact equipment and work methodically, but we’ve completed hundreds of these repairs in Dearborn homes with similar layouts. Flex duct repair in these configurations typically runs $180-$340 per run. Call (844) 685-6342 - we’ll assess access and give you an upfront price.
