Why Bellows Air Duct & Vent Co. Is Livonia’s Preferred Duct Repair & Sealing Company
We’ve worked in Livonia long enough to recognize the house before we walk in. The ranch on a slab foundation with the furnace sitting in the corner of a full basement, the split-level with the return-air chase framed into the wall behind the stairs, the quad-level where the trunk line runs the length of the house at eye level - these aren’t abstract floor plans to us. They’re the specific conditions we prepare for.
Our reputation here is built on not needing to come back. The 90-Day Done Right Promise is stamped on every job - if it’s not right, we make it right, no arguing, no forms to fill out. Calls are answered by a live person 24 hours a day, not an app or a voicemail tree. Our technicians are background-checked, uniformed, and carry the tools and materials to handle flex duct repair, mastic sealant application, and duct insulation replacement without a second trip. That’s especially important in Livonia, where many homes have been owned by the same family since the 1970s or 1980s, and the ductwork has never been professionally addressed since the original installation.
We also offer $50 off any repair over $250, a free second opinion on any written estimate you bring us, and a permanent 5% senior and veteran discount. The price we quote is the price on the invoice - no bait coupons, no changes at the door.
Our Duct Repair & Sealing Services in Livonia
Duct Sealing with Mastic Sealant
Sealing leaky ductwork in Livonia’s 50-70-year-old systems is rarely a tape-and-hope job. The original sheet-metal joints in these postwar homes were typically sealed with fabric tape that has dried and failed decades ago. We apply professional-grade mastic sealant - a thick, brush-applied compound that remains flexible and fills gaps tape cannot reach. In Livonia’s humid continental climate, where summer humidity pushes through basement return boxes and winter heating drives constant airflow, a proper mastic seal holds where other methods fail. We camera-inspect before and after so you see the difference.
Flex Duct Repair
Flex duct in Livonia attics and crawlspaces suffers from a specific set of problems. The insulation wrap compresses over time, the inner liner tears at connection points, and in some of the tighter attic spaces common to split-level additions, the duct gets crushed by stored items or its own sagging weight. We replace damaged flex duct with properly sized, insulated runs, support it to prevent future sagging, and seal every connection with mastic. Most flex duct repairs in Livonia run $180-$340 and are completed in the same visit.
Metal Duct Repair
The galvanized steel trunk lines and branch ducts in Livonia’s original construction are durable but not immortal. We’ve found rust-through at the bottom of horizontal runs where condensation collects, separated seams at elbows, and in one memorable case on St. Johns Avenue, a 1968 furnace plenum with a return-air chase built from wood and drywall that had never been meant to carry air. Our crew removed a section of drywall, cleaned 55 years of debris from the structural framing, applied mastic sealant to seal the chase properly, and replaced the deteriorated fiberglass liner with smooth aluminum interior to stop fiber shedding. Metal duct repair in Livonia typically ranges from $320-$580 depending on access and extent.
Duct Insulation Replacement
Livonia homes need duct insulation more than newer construction in Northville or Canton for a straightforward reason: the original 1960s fiberglass interior liner inside those steel trunk lines has often deteriorated after decades of thermal cycling. The pronounced humidity swings - muggy Lake Erie-influenced summers followed by dry, heavily heated winters - create repeated condensation cycles inside basement ductwork. When that original liner is actively shedding fibers into the airstream, or when the exterior insulation wrap on flex duct has compressed to half its original thickness, you’re losing conditioned air into unconditioned spaces and pulling basement air into the return. We assess liner condition before any agitation, replace degraded insulation with modern materials, and verify with camera inspection. Duct insulation work in Livonia generally runs $400-$720 for main trunk lines.

The right equipment for the specific conditions in these older homes - that’s how we finish in one trip.
Common Duct Repair & Sealing Problems We See in Livonia Homes
- Degraded fiberglass liner shedding fibers. The original 1960s interior liner in Livonia’s ranch basements deteriorates after decades of thermal cycling. Aggressive cleaning without a liner-condition assessment releases those fibers directly into your living space. We inspect first, replace liner when needed, and never make the air quality worse.
- Wood-framed return-air chases packed with debris. A common construction shortcut in Livonia’s 1950-1972 housing stock used framed cavities as return-air paths instead of sealed metal duct. These chases accumulate decades of debris inside the structural framing itself. We access, clean, and seal them properly with mastic so they don’t become a reservoir for mold and dust.
- Condensation cycling promoting mold growth. Livonia’s humid continental climate drives repeated condensation on basement slab near return boxes, especially where ground moisture is present. The combination of humid summers and dry, heavily heated winters creates ideal conditions for mold and dust-mite debris buildup in ductwork that sits cold and then warm.
- Original tape seals failed at every joint. Fifty to seventy years of thermal expansion and contraction has destroyed the original fabric tape at sheet-metal joints. The leaks are often invisible - buried above basement ceilings or inside soffits - but measurable in lost efficiency and uneven heating. We find them with pressure testing and seal them with mastic.

FAQs - Duct Repair & Sealing in Livonia
It can, if the liner is degraded and the cleaning is aggressive. We assess liner condition with camera inspection before any agitation. When we find active deterioration and fiber shedding, we replace the liner with smooth aluminum interior rather than risk making your indoor air quality worse. This is a common condition in Livonia’s ranches and less common in newer suburbs. Call (844) 685-6342 to schedule an assessment - estimates are free.
The proper method is to access the framed cavity, remove accumulated debris, apply mastic sealant to all interior joints to create a sealed air path, and verify with pressure testing. Simply patching the visible opening leaves the structural framing as a debris reservoir. We’ve sealed dozens of these in Livonia’s split-levels and quad-levels, where this construction shortcut was standard practice through the early 1970s. Call for a free estimate.
Most jobs on a standard Livonia ranch with full basement access are completed in four to six hours. If we’re replacing degraded fiberglass liner or accessing wood-framed chases, it may extend toward a full day. We finish in one visit - our trucks carry the materials and equipment for liner replacement, mastic application, and insulation work. You’ll know the timeframe when we quote, not when we arrive.
Livonia’s housing stock is almost entirely 1950-1972 construction with original duct systems now 50-70 years old. The fiberglass liner and exterior insulation have simply reached end of useful life through decades of thermal cycling. Northville has significant newer construction with modern duct materials and better original insulation. In Livonia, we routinely find compressed or degraded insulation that’s losing 20-30% of conditioned air into unconditioned basement space. That’s real money on your utility bill.
Yes. We replace the damaged section with properly sized, insulated flex duct, support it to prevent future crushing, and seal all connections with mastic.
