Why Bellows Air Duct & Vent Co. of Chicago Is Elmhurst’s Preferred Duct Repair & Sealing Company
We’ve worked in Elmhurst long enough to know which streets have the 1950s ranches with original sheet-metal ductwork and which have the split-levels where a kitchen remodel in the 1990s left fiberglass fragments in the return plenum. That kind of local knowledge means we show up with the right tools and materials, not a guess.
Our technicians are background-checked, uniformed, and trained on Rotobrush and Nikro equipment. Every job gets a camera inspection before and after, so you see what we see. Our 90-Day Done Right Promise applies to every Elmhurst home we work on: if it’s not right, we come back at no charge, no paperwork, no arguing.
Calls are answered by a live person, 24 hours a day. Not a voicemail, not an app. If you’ve got a detached workshop with a heating system that’s blowing cold air in January, you want to talk to someone who can dispatch a truck, not leave a message.
We also offer a standing $50 off any repair over $250, a free second opinion on any written estimate, and a permanent 5% senior and veteran discount. The price we quote on the phone is the price on the invoice. No bait coupons, no changes at the door.
Our Duct Repair & Sealing Services in Elmhurst
Metal Duct Repair
Elmhurst’s core neighborhoods are full of homes built between the late 1940s and early 1970s with original sheet-metal trunk-and-branch systems. These ducts weren’t designed for today’s HVAC loads, and after seventy years, joint separation and interior liner deterioration are common. We cut out rusted or collapsed sections, fabricate replacement trunk lines on-site, and seal everything with mastic. A typical metal duct repair in Elmhurst runs $350-$580.
Mastic Sealant Application
We apply professional-grade mastic to every joint, seam, and penetration point. In Elmhurst, this matters more than in newer suburbs because these older metal systems have dozens of joints that have never been properly sealed. The mastic we use is rated for the temperature swings these ducts see through a Chicago winter. Mastic sealing for a full system in Elmhurst typically costs $280-$450.
Flex Duct Repair
Flex duct is common in additions, basement retrofits, and detached garages throughout Elmhurst. It collapses, gets punctured by contractors, or simply degrades after twenty years. We replace flex runs with properly sized, insulated duct and secure it so it doesn’t sag or kink. Flex duct repair in Elmhurst usually runs $180-$340 per run.
Duct Insulation
Ducts routed through unconditioned crawl spaces or attics in Elmhurst lose enormous efficiency in winter. We wrap metal and flex runs with formaldehyde-free insulation, sealed at all seams. This is especially important for homes near Salt Creek, where humidity in summer creates condensation on cold duct surfaces. Duct insulation work in Elmhurst typically costs $320-$520.

Trusted Brands We Service in Elmhurst
We carry Rotobrush and Nikro equipment on every truck, and we stock Honeywell controls and dampers for the zoning repairs these older Elmhurst systems often need. Most Elmhurst jobs are completed in a single visit. The brands we use are the same ones serious HVAC contractors specify, not the discount-house generics that fail in two seasons.
Common Duct Repair & Sealing Problems We See in Elmhurst Homes
- Original sheet-metal systems with joint separation. The post-WWII ranch and Cape Cod homes that dominate Elmhurst’s 60126 ZIP were built with unsealed trunk-and-branch ductwork. Decades of thermal cycling have opened gaps at every joint. We find air leaks costing homeowners 20-30% efficiency loss before we even touch the furnace.
- Rust-through from flood history near Salt Creek. Homes in the low-lying eastern neighborhoods have documented moisture and periodic flooding histories. Our technicians regularly find rusted-out metal duct runs and microbial growth in basements and crawl spaces. This isn’t a standard cleaning job; it requires metal replacement and remediation-level sealing.
- Collapsed flex duct in detached workshops and garages. Elmhurst’s acreage properties often have outbuildings with heating systems that were installed as afterthoughts. The flex duct runs through unconditioned space, sagging over time, getting crushed, or simply falling apart. We replace these with properly supported, insulated runs.
- DIY mastic jobs that missed the real leaks. Self-reliant homeowners in Elmhurst often try to seal their own ducts but can’t reach or identify hidden joint separations. We use smoke testing and pressure diagnostics to find the leaks that matter, not just the ones you can see.
We recently serviced a detached workshop on a multi-acre property near Salt Creek. The heavy-duty 8-foot sliding door needed a new torsion spring and opener upgrade. Inside, the metal duct system had rust-through from past flooding; we applied mastic sealant to all joints and replaced a collapsed flex run, all in a single trip.

FAQs - Duct Repair & Sealing in Elmhurst
Yes, we stock heavy-duty springs, openers, and duct materials for exactly this situation. We recently completed a single-trip repair on a Salt Creek area workshop with an 8-foot sliding door and rusted metal ductwork. The technician replaced the torsion spring, upgraded the opener, applied mastic sealant to all duct joints, and replaced a collapsed flex run. Most Elmhurst workshop calls are wrapped in one visit. Call (877) 502-3903 to schedule.
Homes near Salt Creek have well-documented moisture and periodic flooding history that causes rust-through and microbial growth on duct runs in basements and crawl spaces. This requires remediation-level metal repair and replacement, not just standard cleaning or sealing. Western Elmhurst neighborhoods at higher elevation rarely see this pattern. If you’re in the flood zone, we inspect for rust and biological growth as standard practice. Call (877) 502-3903 for a camera inspection.
Original sheet-metal trunk-and-branch systems in Elmhurst split-levels typically have unsealed joints, deteriorated interior fiberglass liner, and air leaks at the furnace plenum connection. These systems were never designed for modern HVAC loads, and seventy years of thermal cycling has opened gaps that simple vacuuming won’t fix. We use smoke testing to locate leaks, then seal with mastic and replace damaged sections. A typical split-level sealing job in Elmhurst runs $350-$580. Call (877) 502-3903 for an exact quote.
Yes, we regularly replace collapsed, uninsulated, or improperly supported flex duct in Elmhurst detached garages and workshops. These runs often degrade faster than indoor ductwork because they’re exposed to temperature extremes and physical damage. We install properly sized, insulated flex with secure supports that prevent sagging. Per-run replacement typically costs $180-$340. Call (877) 502-3903 to schedule.
Yes, we carry heavy-duty opener components and torsion springs for oversized doors on every service truck. Elmhurst’s acreage properties with detached workshops need heavier-duty hardware than standard residential openers, and we don’t make you wait for a parts order. Most installations are completed same-day. Call (877) 502-3903 to confirm availability for your specific model.
