Call (844) 685-6342 and we’ll get you a real person, 24 hours a day.
West Town’s housing stock is unlike anywhere else in Chicago. The brick two-flats and three-flats along Haddon, Thomas, and the surrounding streets were built for gravity hot-air furnaces, then retrofitted with forced-air systems in the 1950s and later. Those conversions left behind oversized sheet-metal trunk lines routed through masonry chases and basement ceiling cavities that were never designed to be sealed or inspected. Our Duct Repair & Sealing crews have worked these buildings for decades. We know where the leaks hide, what the access problems look like, and how to fix them without tearing your walls apart.
Why Bellows Air Duct & Vent Co. Is West Town’s Preferred Duct Repair & Sealing Company
We’ve been serving Chicago-area homeowners since 1984, and West Town has been part of our route for most of those 42 years. Ray Castillo built this company on the idea that a job done right shouldn’t need a callback, and that starts with showing up when we say we will. Our technicians know the difference between a courtyard greystone on Augusta and a narrow two-flat on Haddon, and they bring equipment sized for both.
Our reputation in 60622 is built on camera-verified results. Every job gets inspected before we start and after we finish, with footage you can see. No claims without proof. West Town customers have told us for years that they appreciate a company that answers the phone with a live person, not an app or a voicemail maze. That’s how we’ve always operated.
Response time to West Town is typically same-day or next-morning, depending on when you call. Emergency air-leak situations, like a disconnected trunk line dumping heated air into a basement cavity, get priority scheduling. We don’t bait-switch on pricing, either. The number we give you on the phone is the number on the invoice. Our 90-Day Done Right Promise covers every job in writing, no paperwork required if something needs attention.
Our Duct Repair & Sealing Services in West Town
Duct Sealing
Sealing West Town’s legacy ductwork is a specialty we’ve developed over four decades. Those 1950s forced-air retrofits in Ukrainian Village two-flats were never sealed to modern standards. Open seams at every joint leak conditioned air into basement cavities and pull in dust from crawlspaces. We seal what we can reach with mastic and mechanical fasteners, and we document every sealed joint with camera footage. A typical duct-sealing job in West Town runs $320-$580, depending on linear footage and access difficulty.
Flex Duct Repair
Postwar flex-duct splices into aging metal trunks are common in East Village renovations, and they’re often where we find the worst problems. Uninsulated flex draped against hot water pipes causes condensation and mold. In winter, that same flex can collapse from negative pressure when the furnace kicks hard. We replace damaged sections with insulated flex rated for Chicago’s temperature swings, and we reroute away from plumbing where possible. Most flex repairs in West Town fall between $180-$340.
Metal Duct Repair
The original sheet-metal trunk lines in West Town greystones weren’t built to last 70 years, but many have. We repair separated seams, corroded sections, and failed hangers without replacing entire systems when it’s practical. Sometimes a partial replacement of the worst section, sealed properly into the remaining sound metal, is the square deal. Metal duct repair in 60622 typically ranges $280-$520.
Duct Insulation
Basement and crawlspace ducts in West Town lose enormous heat in winter. Chicago’s heating season runs November through March, and uninsulated metal in a 45-degree basement is like heating the outdoors. We install foil-faced fiberglass or closed-cell wrap on accessible runs, paying special attention to the chase penetrations where masonry meets metal. Insulation jobs start around $240 for limited runs and run to $600 for full basement systems.
Mastic Sealant Application
Mastic is our preferred sealant for West Town’s legacy metal. Unlike tape, which fails in temperature swings, mastic remains flexible and airtight for decades. We apply it with brushes, trowels, and flexible endoscopic applicators for tight masonry chases where standard tools won’t reach. The oversized gravity-furnace plenums in these buildings prevent access for conventional equipment, so we’ve adapted. Mastic sealing adds 30-60 minutes to a typical job but produces results that last. Figure $350-$620 for a full mastic treatment.
Air Leak Repair
Air leaks in West Town homes aren’t minor inefficiencies. They’re energy drains and indoor air quality problems. Leaks at plenum connections pull basement air, radon, and construction dust into your supply. We pressure-test, locate, and seal with a combination of mechanical fastening and mastic. Our Duct Repair & Sealing in West Town includes post-repair pressure verification so you know the fix held.

Trusted Brands We Service in West Town
We stock parts and specify equipment from Rotobrush, Abatement Technologies, and Aprilaire, the same brands serious HVAC contractors use. For West Town’s older systems, that means flexible cleaning and sealing tools that fit into masonry chases built before duct maintenance existed as a trade. We don’t show up hoping we have the right gear. Our trucks carry multiple applicator sizes, inspection cameras with articulating heads, and mastic rated from 30°F below to 200°F above, which covers anything a Chicago winter or summer throws at it. Most repairs are completed in a single visit because we’ve learned what these buildings need.
Common Duct Repair & Sealing Problems We See in West Town Homes
- Original sheet-metal trunk lines with open seams. The 1950s retrofits in West Town two-flats used snap-lock or drive-cleat joints with no sealing. Seventy years of thermal cycling has opened gaps at every joint. Conditioned air leaks into basement cavities while the system pulls in dust and debris from crawlspaces. We find this on nearly every pre-1980 building we inspect in 60622.
- Oversized plenums in inaccessible masonry chases. Gravity-furnace plenums were built big because they didn’t need pressure. Forced-air retrofits left those same plenums in place, now with a modern blower trying to pressurize a volume three times what’s needed. Standard sealing tools don’t fit. We use flexible endoscopic mastic applicators that extend our reach by four feet, though the tight access adds significant time per job.
- Uninsulated flex-duct splices against plumbing. East Village renovations often splice new flex into old metal trunks to serve added rooms. When that flex drapes against hot water pipes, summer humidity condenses on the cold duct surface. Mold follows. We’ve rerouted and re-insulated dozens of these in West Town, usually finding the problem has been active for years before anyone looks.
- Construction dust infiltration from gut renovations. West Town’s gentrification has meant heavy construction on nearly every block. Drywall particulate, insulation fibers, and demolition debris enter existing duct systems through leaks that should have been sealed decades ago. Sealing first, then cleaning, is the only sequence that makes sense. Otherwise you’re cleaning a system that recontaminates itself in a week.
Pricing for Duct Repair & Sealing in West Town, IL
Here’s what honest pricing looks like for West Town’s market. These ranges reflect the access challenges and legacy conditions specific to 60622 housing:
| Service | Typical Range in West Town |
|---|---|
| Basic air-leak sealing (accessible ducts) | $280-$420 |
| Full mastic sealant application | $350-$620 |
| Flex duct repair/replacement | $180-$340 |
| Metal duct repair (partial section) | $280-$520 |
| Duct insulation (basement runs) | $240-$600 |
| Combination sealing + insulation | $480-$850 |
What moves you within these ranges? Access difficulty is the big one. A basement with a full 7-foot ceiling and exposed ductwork is straightforward. A trunk line buried in a masonry chase behind a finished wall takes longer. The age and condition of existing metal matters too, corroded sections need repair before sealing. We disclose your exact price before any work begins, no changes at the door. Estimates are free, and we offer $50 off any repair over $250. Call (844) 685-6342 for yours.

FAQs - Duct Repair & Sealing in West Town
Yes, in most cases we can seal legacy trunk lines without demolition. We use flexible endoscopic applicators to reach mastic into masonry chases where standard tools won’t fit. On a Ukrainian Village three-flat along Thomas Street, we found a 2005 Carrier furnace pushing air through the original 1950s trunk lines with gaping seams at every joint. We sealed 22 leaks with mastic and installed a duct liner in the main chase, cutting the homeowner’s heating bills by an estimated 18% before the next Chicago winter. Camera inspection before and after documents what we reached and what we sealed. Call (844) 685-6342 for a free assessment of your specific layout.
Sealing alone won’t remove existing dust, but it’s essential to preventing recontamination. Unsealed ducts in West Town’s older buildings act like vacuum lines, pulling construction particulate from wall cavities and basement spaces into your living areas. We seal first, then clean, so the system stays clean. Our camera inspection identifies the leak points that renovation dust is entering through. Most East Village renovation-related sealing jobs run $320-$550. Mention your renovation schedule when you call and we’ll coordinate timing.
Yes, chase penetrations are a common failure point in West Town two-flats and they’re absolutely sealable. We use mastic with reinforcing mesh for larger gaps, and mechanical support where the duct has settled against brick. These penetrations often leak both air and debris from wall cavities, so sealing them produces noticeable improvements in both efficiency and air quality. The brick-and-plaster construction in 60622 buildings makes these repairs slower than wood-frame work, but we’ve done hundreds. Expect $300-$480 for typical chase-penetration sealing on Haddon or similar streets.
Replacement is rarely necessary if the metal is structurally sound. We’ve found that properly sealed 1950s trunk lines often perform as well as new, provided they’re supported correctly and not actively corroded. Replacement makes sense when metal is rusted through, when the original sizing is wildly wrong for modern equipment, or when access for sealing would require more demolition than replacement. For most West Town homeowners, sealing is the square deal, runs $280-$620 versus $2,000-$4,500 for full replacement, and carries our 90-Day Done Right Promise either way. We’ll show you camera footage of your specific ducts and give you an honest recommendation.
We do not use aerosol-based sealing in West Town’s legacy housing stock. Aerosol systems require a duct system that can be pressurized and sealed at all registers, which isn’t practical with the mixed metal-and-flex configurations and open chases common in 60622. More importantly, aerosol sealant can’t address the structural seam separation and chase-penetration gaps we find in these buildings. Hand-applied mastic with mechanical fastening is slower but produces repairs that last decades, not years. We stand behind our work with a 90-Day Done Right Promise, no paperwork required if you need us back. Call (844) 685-6342 to discuss the right approach for your system.
