When you call (877) 502-3903, a live person answers, day or night. We’ll give you an honest price before we start, and we back every job with our 90-Day Done Right Promise in writing.
Why Bellows Air Duct & Vent Co. of Chicago Is Schiller Park’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in Schiller Park one house at a time, mostly through neighbors telling neighbors. Our technicians know to expect original sheet-metal ductwork in the postwar ranches near Lawrence Avenue, and they know the FAA sound-insulated homes around the village’s eastern edge need a different approach to return sealing than uninsulated stock just blocks away in Franklin Park.
Homeowners here call us back because we show up when we say we will, in uniform, with background-checked crews who answer to a live dispatcher 24 hours a day. We camera-inspect every duct system before we quote and again before we leave, so you see what we see. No bait coupons, no price changes at the door. The number we give on the phone is the number on the invoice.
Ray Dempsey has run Bellows since 2012 under a simple standard: if it’s not done right, we make it right, no paperwork, no arguing. That 90-Day Done Right Promise is stamped on every job we do in Schiller Park, whether it’s a mastic seal on a basement plenum or a full flex duct replacement in an attic.
Our Duct Repair & Sealing Services in Schiller Park
Duct Sealing
Schiller Park’s 1950s-1960s homes were built fast, and the original duct sealing was often tape that dries and curls after six decades. Worse, the FAA’s O’Hare noise mitigation program retrofitted tighter windows and envelopes in many homes here, which reduced natural air exchange and concentrated aviation particulates inside. We seal supply and return plenums, trunk lines, and branch takeoffs with professional-grade mastic sealant, the same product serious HVAC contractors specify. A typical duct sealing job in Schiller Park runs $280-$450 for a single-system home. We pressure-test after we seal to verify the drop.

Metal Duct Repair
Original galvanized steel ductwork in Schiller Park bungalows and ranches is built to last, but after 60+ years it corrodes at seams, separates at joints, and develops whistle-inducing gaps. We patch small breaches with sheet metal and sealant, reinforce sagging trunk lines with proper support, and replace sections too far gone to save. Metal duct repair in Schiller Park typically runs $180-$380 for localized work, or $520-$650 if we’re rebuilding a major trunk section. We’ll tell you straight when repair makes sense and when replacement is the square deal.

Flex Duct Repair
Flex duct was retrofitted into many Schiller Park attics and crawl spaces in the 1980s and 1990s, and it’s now reaching the end of its service life. We see crushed, kinked, and torn flex runs that choke airflow and let unconditioned attic air into the system. Our crew replaces degraded flex with insulated aluminum ductwork, properly supported and sealed. Typical flex duct replacement in Schiller Park runs $220-$480 per run depending on length and attic access. We recently repaired a flex duct run in a 1950s ranch on Irving Park Road where the homeowner had lived for 30 years without servicing. The original fiberglass duct board was shedding particles, and the system was pulling in airport-grade fine dust through gaps at the plenum. We sealed all joints with mastic and replaced the degrading flex section with insulated aluminum duct.

Duct Insulation
Uninsulated attic duct runs are common in Schiller Park’s ranch homes, and Chicago’s humid summers turn them into condensation factories. Wet fiberglass breeds mold. Wet metal corrodes. We wrap existing ductwork with formaldehyde-free insulation or replace uninsulated runs with pre-insulated product. Duct insulation in Schiller Park typically runs $340-$580 for a standard ranch attic. The payoff is immediate: less condensation, more stable delivery temperatures, and lower summer humidity in the living space.

Common Duct Repair & Sealing Problems We See in Schiller Park Homes
- Degrading fiberglass duct board sheds particles into airflow. The 1950s-1960s ranches near Lawrence Avenue and 17th Street frequently retain original fiberglass-lined duct board that breaks down after 50-60 years. These particles clog evaporator coils, reduce airflow, and circulate through the home. We replace degrading sections with sealed metal or insulated flex.
- O’Hare sound-insulated homes trap aviation particulates in duct systems. The FAA noise mitigation program tightened building envelopes across Schiller Park, but many contractors didn’t upgrade return sealing proportionally. The result is concentrated jet exhaust and ultra-fine combustion byproducts cycling through ducts at higher concentrations than in unsealed neighboring homes. We seal returns and upgrade filtration to match the tighter envelope.
- Uninsulated attic ducts grow mold in summer humidity. Ranch homes with ductwork in vented attics see condensation on cold supply lines when humid Chicago air hits 80+ degrees. We’ve found active mold growth in July on ducts that were clean in April. Insulation and proper attic ventilation solve it.
- Original metal ductwork separates at seams after decades of thermal cycling. Chicago’s furnace runs hard from November through March, expanding and contracting sheet metal thousands of times. Seams loosen, mastic cracks, and conditioned air leaks into basements and crawl spaces. We reseal with modern mastic that flexes with the metal.

FAQs - Duct Repair & Sealing in Schiller Park
Yes. The tighter building envelope concentrates aviation particulates and indoor pollutants, so return duct sealing and filtration upgrades matter more here than in uninsulated homes just blocks away. We seal returns more aggressively in sound-insulated homes and often recommend higher-grade filtration to match the reduced air exchange. Call (877) 502-3903 and we’ll assess your specific envelope - estimates are free.
Original ductwork in 1960s Schiller Park bungalows should be camera-inspected every 3-5 years, and sooner if you notice uneven heating, rising energy bills, or visible dust at registers. The combination of 60-year-old materials and O’Hare’s particulate load accelerates degradation beyond what the industry-standard 5-7 year interval assumes. Our $89 Seasonal Tune-Up includes full camera inspection. Call (877) 502-3903 to schedule.
Most original 1950s galvanized ductwork in Schiller Park can be repaired if the metal itself is structurally sound - we patch holes, reseal seams, and reinforce supports. We recommend replacement only when corrosion has thinned the metal extensively or when the original layout is so poorly designed that repair won’t solve airflow problems. A typical metal repair runs $180-$380; full replacement starts around $1,800. We’ll show you the camera footage and give an honest recommendation.
It can. The fine combustion contamination unique to Schiller Park’s aviation corridor often requires additional cleaning before we can properly seal or repair ductwork, which adds $80-$150 to jobs where buildup is heavy. This is not a factor we see in River Grove or Northlake, where the particulate profile is different. We assess this during our free estimate and tell you before we start if extra cleaning is needed.
Failed original duct sealing at the plenum and trunk line joints, combined with degrading fiberglass duct board in attics and crawl spaces. The 1950s ranches along Irving Park Road and near Lawrence Avenue were built with tape seals that dried out decades ago, and the fiberglass lining is now shedding. We typically find both problems on the same job: reseal the metal with mastic, replace the degrading fiberglass sections. Call (877) 502-3903 for a free inspection - we’ll show you exactly what your system needs.
