Why Bellows Air Duct & Vent Co. of Chicago Is Glen Ellyn’s Preferred Duct Repair & Sealing Company
We’ve been serving Glen Ellyn homeowners since 2012, long enough to know the difference between a 1920s Colonial with gravity-furnace conversion ductwork and a 1965 split-level off Roosevelt Road. Our Duct Repair & Sealing team has worked on both, and the before-and-after camera footage lives in our files.
Our reviews from Glen Ellyn customers consistently mention the same things: we show up when we say we will, we explain the problem without talking down, and the price on the phone matches the price on the invoice. We’re not the cheapest outfit advertising a $49 coupon in the PennySaver. We’re the company you call when that outfit leaves your ducts worse than they found them.
Response time to Glen Ellyn is typically same-day or next-morning. We keep common fittings and mastic sealant stocked for the village’s predominant duct types, so most jobs finish in a single visit. And every repair carries our 90-Day Done Right Promise in writing - if it’s not right, we return at no charge, no paperwork, no arguing.
Our Duct Repair & Sealing Services in Glen Ellyn
Duct Sealing
Leaky ducts steal 20-30% of your heating and cooling before it reaches your rooms. In Glen Ellyn, we see this constantly in split-levels where floor-cavity transitions have worked loose over fifty years of thermal cycling. We seal with mastic and fiberglass mesh at every joint, then pressure-test to verify. The result is air that goes where it’s supposed to, not into your walls or attic.
Mastic Sealant Application
Mastic is the only proper sealant for metal ductwork - tape dries and fails, especially in Glen Ellyn’s climate of hot humid summers and dry forced-air winters. We brush mastic into every seam and joint, building a flexible, permanent seal that outlasts the house. For homes near the historic downtown with original gravity-furnace trunk lines, mastic is often the difference between a system that works and one that labors.
Duct Insulation
Uninsulated metal ducts in attics and crawl spaces sweat when humid Glen Ellyn air hits their cool surface. That condensation breeds mold, rusts fittings, and drips through ceiling drywall. We wrap with formaldehyde-free fiberglass insulation, sealed with vapor barrier, to keep the air inside your ducts at the temperature you paid to create. This is especially critical for the village’s many 1950s-1970s homes where original insulation has crumbled to dust.
Flex Duct Repair
The flexible duct runs common in 1970s Colonials tear at attic truss contact points or collapse where supports have failed. We replace damaged sections with new insulated flex, properly supported and sealed, or transition to hard pipe where the run allows. Either way, we camera-inspect before and after so you see the difference.
Metal Duct Repair
Rusted sections, disconnected collars, and damaged dampers in original sheet-metal ductwork can’t be patched with tape and hope. We cut out damaged sections, fabricate replacements, and seal with mastic for a repair that lasts. For Glen Ellyn’s older homes with oversized round trunks from gravity-furnace conversions, we adapt our tools and techniques rather than forcing a one-size approach.

Trusted Brands We Service in Glen Ellyn
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Honeywell - the same brands serious HVAC contractors specify when they’re working on their own homes. For Glen Ellyn’s oversized gravity-furnace trunks, we use Rotobrush systems with extended-reach attachments that standard cleaning tools can’t match. We stock common fittings and sealants locally, so a typical repair doesn’t wait on parts. When we pull up to your home near Main Street or out by the Village Links, we’re carrying what we need to finish the job that day.
Common Duct Repair & Sealing Problems We See in Glen Ellyn Homes
- Uninsulated round trunk lines from gravity-furnace conversions sweat in humid summers. Glen Ellyn’s July dew points regularly spike above 70°F, and cool air inside uninsulated metal ducts condenses moisture that mold colonizes within weeks. Cleaning removes the mold; sealing and insulation stop it from returning.
- Hidden leaks at floor-cavity transitions in split-levels waste energy for decades. The 1950s-1970s split-levels that dominate Glen Ellyn’s postwar neighborhoods have duct runs through floor cavities and interior stud bays that no homeowner ever sees. Pressure testing reveals leaks our technicians then access and seal properly.
- Oak and maple pollen loads filters and ducts faster than in less-forested suburbs. Glen Ellyn’s dense mature canopy is beautiful and a point of civic pride, but April-May pollen surges and October leaf-decomposition particulate visibly load return-air grilles. Without sealed ductwork, that debris pulls into the system and stays there.
- Original sheet-metal ductwork in 50-70-year-old homes has never been cleaned or sealed. The postwar Colonials and split-levels that fill out the village beyond the historic core have ductwork at or past its functional lifespan. Seams have opened, supports have failed, and accumulated debris restricts airflow to the point where systems run continuously without satisfying the thermostat.

FAQs - Duct Repair & Sealing in Glen Ellyn
Yes. We regularly work on gravity-furnace conversion ductwork in Glen Ellyn’s historic neighborhoods near the Metra station and Main Street. The 14-inch round metal trunks are larger than standard tools handle, so we use Rotobrush systems with extended-reach attachments and apply mastic sealant by hand at every joint. We recently repaired and sealed ductwork in a 1940s Colonial near the Metra station where the original gravity-furnace trunk lines were uninsulated 14-inch round metal ducts. Our crew used Rotobrush tools to clean the oversized lines, then applied mastic sealant to reseal leaky joints that were drawing in attic dust and pollen from the village’s heavy oak canopy. Call (877) 502-3903 for a free inspection - we’ll show you exactly what we’re working with.
We locate leaks with a pressure test first, then access through existing registers, return grilles, or small strategic openings that we restore afterward. For the multi-level duct runs common in Glen Ellyn split-levels, we often find the worst leaks at floor-cavity transitions between levels - places no homeowner has seen in fifty years. Our camera shows you the damage before we cut any access. Estimates are free; call (877) 502-3903 to schedule.
Glen Ellyn’s dense oak and maple canopy produces pollen loads that exceed what comparably aged suburbs like Lombard experience. Without sealed ductwork, that pollen pulls past the filter and adheres to interior duct walls, creating a reservoir that feeds back into your air each season. Cleaning removes the buildup; sealing the return ductwork stops the infiltration. For a permanent fix, we seal the leaks and verify with a pressure test. Call (877) 502-3903 - we’ll diagnose whether sealing or a combination of cleaning and sealing is the right approach.
Insulation is the only reliable solution. Mastic sealing stops air leaks, but uninsulated metal in Glen Ellyn’s humid attic and crawl spaces will still sweat when cool air hits 70°F+ dew point air. We wrap ducts with formaldehyde-free fiberglass insulation and vapor barrier, sealed at every seam. For homes with original gravity-furnace trunks, this is often the critical step that cleaning alone misses. Free estimates: (877) 502-3903.
Yes. We replace torn or collapsed flex duct with new insulated flex, properly supported to prevent contact with attic trusses, and sealed with mastic at every connection. The original 1970s flex in Glen Ellyn’s Colonials has typically degraded where it touches framing or where supports have failed. We camera-inspect the full run to find all damage, not just the obvious tear. Most replacements finish in a single visit. Call (877) 502-3903 for an exact quote - estimates are free, and we honor our Free Second Opinion on Any Written Estimate if you’ve already been quoted elsewhere.
