We’ve been working in Cicero since 2012, and we know the town’s housing stock like our own toolbox. The 1920s brick bungalows along 16th Street, the two-flats clustered near Cermak Road, the postwar conversions stretching toward the old Western Electric site - these aren’t abstract addresses to us. They’re buildings with specific duct problems that repeat often enough we’ve developed methods for them. Our Duct Repair & Sealing team carries the fittings and sealants that fit Cicero’s legacy systems, not just standard new construction.
Why Bellows Air Duct & Vent Co. Is Cicero’s Preferred Duct Repair & Sealing Company
Cicero homeowners don’t call us for flash. They call because their neighbor called, or because they got tired of a company that quoted one price and invoiced another.

Our Duct Repair & Sealing Services in Cicero
Duct Sealing
Sealing is often the right first move in Cicero’s older homes. We use mastic sealant - a brush-applied, fiber-reinforced compound that fills gaps in metal joints and seams far better than tape alone. In a typical Cicero bungalow, we’ll find 15-30% of conditioned air leaking into walls, crawl spaces, or the basement plenum before it reaches the rooms. Mastic sealing brings that down to under 5% in most cases. We seal first, then verify with a camera pass and pressure check.
Metal Duct Repair
Original galvanized ductwork in Cicero’s pre-1950 housing rusts at the seams and collars, especially where decades of humidity cycling have corroded the protective zinc layer. We cut out failed sections, fabricate replacement runs on-site, and reconnect with sealed transitions. Where the original trunk line is sound but局部 damaged, a targeted metal repair preserves the system without the cost of full replacement. In a 1920s two-flat on 16th Street, we found a spliced flex-duct junction where collapsed liner had rerouted airflow into a dead crawl space. We removed the old section, installed a new insulated metal transition with mastic sealant, and restored balance to both floors - keeping the homeowner’s vintage gravity-to-forced-air conversion intact.
Flex Duct Repair
Flex-duct extensions added during 1950s and 1960s conversions are a recurring problem in Cicero. The plastic liner collapses at bends, the insulation compresses, and the junction points to original metal trunks loosen. We replace collapsed flex runs with properly sized new sections, support them to prevent sagging, and seal every connection. A standard brush cleaning won’t fix a flex duct that’s collapsed internally - the airflow problem returns until the physical damage is addressed.
Duct Insulation
Cicero’s crawl-space and basement plenums lose significant heat in winter and gain humidity in summer. We install foil-faced fiberglass or closed-cell insulation around repaired duct runs, particularly where metal transitions replace old flex sections. Proper insulation keeps the air you’ve paid to condition at temperature until it reaches the register, and it reduces condensation that leads to mold in humid basement environments.

Trusted Brands We Service in Cicero
We stock parts and sealants from Aprilaire, Abatement Technologies, and Rotobrush - the same brands serious HVAC contractors specify when they’re doing the job right, not cutting corners. For Cicero homeowners with older systems, this matters because legacy ductwork often needs adapters and transition fittings that aren’t sitting on a big-box shelf. We carry the inventory to fabricate repairs on-site, which means most jobs finish in one visit instead of stretching across multiple appointments.
Common Duct Repair & Sealing Problems We See in Cicero Homes
- Rusted seams on galvanized ductwork. Decades-old galvanized ductwork in Cicero’s bungalows rusts at the seams during humidity swings, creating hidden leaks that can’t be mastic-sealed without first removing compacted debris. We scrape, clean, then seal - in that order.
- Collapsed flex-duct junctions. Spliced-on flex-duct extensions from 1950s conversions collapse at the junction points, blocking airflow and pressurizing unsealed sections. The fix is physical replacement, not more tape.
- Cross-contamination between floors. Interconnected duct runs between floors of Cicero two-flats allow cross-contamination; inadequate separation during sealing leaves upstairs units pulling debris from the basement plenum. We map the runs before sealing anything.
- Industrial particulate legacy. Cicero’s east-side homes near the former Western Electric Hawthorne Works site have duct systems that trapped decades of industrial particulate in sharp-bend retrofit runs - a legacy contaminant load that standard cleaning can’t fully remediate without sealing and repair. Sealing prevents recontamination once the debris is removed.

FAQs - Duct Repair & Sealing in Cicero
Yes, we regularly seal and repair original galvanized ductwork in Cicero bungalows, provided the metal is structurally sound. We clean the seams, apply mastic sealant to joints and collars, and replace any sections that have rusted through. Where the galvanized is too far gone, we fabricate matching metal transitions that fit the existing trunk line. Call (844) 685-6342 and we’ll camera-inspect to tell you what’s salvageable - estimates are free.
Yes, we’ve found compacted industrial particulate in duct systems east of Laramie Avenue, particularly in homes with 1950s forced-air conversions that added sharp bends where debris collects. Standard cleaning removes loose material, but sealing is critical afterward - without sealing the gaps and seams, the remaining fine particulate recirculates. We camera-inspect to assess the load, then recommend cleaning followed by targeted mastic sealing to prevent recontamination.
Sealing helps, but if the flex-duct itself has collapsed internally or the liner has detached, sealing the joint won’t restore airflow. We camera the run first. When the flex is damaged, we replace the section with new insulated flex or a metal transition, then seal. In Cicero two-flats, we also check whether the upstairs and downstairs runs are properly separated - an interconnected system will keep circulating problems even after sealing.
Most Cicero systems benefit from repair and sealing rather than full replacement, especially where original metal trunk lines are structurally sound. Replacement becomes the better choice when multiple sections are rusted through, the system was poorly designed from the conversion, or repair costs approach 60% of replacement. We’ll show you the camera footage and give you both numbers - no pressure either way. Our $50 off repairs over $250 and free second opinions apply either direction.
Yes, if done with the right materials. We use fiber-reinforced mastic rated for temperature cycling, not cheap foil tape that peels in damp conditions. For crawl-space plenums common to Cicero bungalows, we also inspect for standing water or foundation moisture that would undermine any seal. Addressing the humidity source - not just the duct leak - is what makes the repair last. Our 90-Day Done Right Promise covers the seal; if it fails, we return at no charge.
