Why Bellows Air Duct & Vent Co. of Chicago Is Kenwood’s Preferred Duct Repair & Sealing Company
We’ve worked in Kenwood for over four decades. Ray Dempsey, who leads our company, started this business on the principle that a tradesman should stand behind his work without making the homeowner fill out forms to prove it. That still holds.
Our technicians are background-checked and uniformed. They arrive with camera inspection equipment from Rotobrush and Nikro, and they photograph your ductwork before touching it and again when finished. You see what we see. No claims without proof.
We answer our phones 24 hours a day with a live person, not a menu tree. Most Kenwood jobs are completed in a single visit. Our 90-Day Done Right Promise means if something isn’t right, we return at no charge. No paperwork, no arguing. That’s been our policy since 2012.
Kenwood’s housing stock demands specific expertise. The ZIP 60615 contains some of Chicago’s grandest surviving residential architecture from the 1880s through the 1920s, homes built before Kenwood HVAC Cleaning systems existed. Many were later subdivided and reconverted, leaving behind labyrinthine duct runs that confuse technicians trained only on suburban tract construction. We know the difference.
Our Duct Repair & Sealing Services in Kenwood
Duct Sealing
Sealing in Kenwood isn’t a matter of running tape around joints. Many historic mansions here have ductwork retrofitted into original coal-chute openings or dumbwaiter shafts, creating odd angles and dead-leg runs that require custom sealing work not seen in newer homes. We use mastic sealant and fiberglass mesh on metal connections, and we verify every seal with a camera inspection. A typical duct sealing job in Kenwood runs $280-$450 for a single system.
Metal Duct Repair
Kenwood’s original cast-iron or heavy-gauge sheet-metal trunk lines from 1920s-1940s retrofits are often buried in finished walls and plaster ceilings. These systems look complete on a floor plan but frequently contain sealed-off branches that haven’t moved air in 40-plus years. We locate these dead zones, patch corrosion holes with proper sheet-metal sleeves, and restore airflow without tearing out historic plaster. Metal duct repair in Kenwood typically costs $320-$580 depending on accessibility.
Flex Duct Repair
Flex duct repairs in Kenwood’s attics often fail because the original supports were designed for heavier metal ducts and sag under the flex’s weight. The result is collapsed runs, kinked bends, and torn connections. We replace damaged flex with properly supported runs rated for the application, not just patch and hope. Expect $240-$420 for most flex duct repairs in Kenwood homes.
Duct Insulation
Chicago’s proximity to Lake Michigan produces high summer humidity that promotes condensation and mold growth inside older, less-insulated ductwork common in Kenwood’s historic homes, which is why Air Duct Cleaning - Kenwood is often needed. We insulate exposed runs in basements, crawl spaces, and attics using materials appropriate for each location. Proper insulation also prevents heat loss during Chicago’s extended heating season, when furnaces often run from October through April. Duct insulation in Kenwood generally runs $180-$340 per run, with full system insulation at $450-$780.

Trusted Brands We Service in Kenwood
We carry professional-grade equipment and materials from Rotobrush, Nikro, Honeywell, and Aprilaire, the same brands serious HVAC contractors specify for their own jobs. For Kenwood homeowners, this means we stock the right mastic compounds, fiberglass mesh, metal sleeves, and insulation wraps for older, non-standard duct configurations without waiting on special orders. Most repairs are completed the same day we arrive. We don’t substitute cheaper materials that fail in two seasons. The brands we use are chosen because they last.
Common Duct Repair & Sealing Problems We See in Kenwood Homes
- Mastic sealant fails within a year on old galvanized ducts if the surface isn’t properly cleaned of decades of grime and rust. We see this frequently in Kenwood’s 1920s-era metal trunk lines, where previous contractors slapped sealant over dirty metal and called it done. We grind, brush, and prep every surface before applying new mastic.
- Flex duct repairs collapse in Kenwood attics because the original supports were designed for heavier metal ducts and sag under the flex’s weight. The sag creates dead air zones and strains connections until they tear. We install proper support straps and hangers rated for flex duct weight and span.
- Sealing off abandoned branches from 1940s retrofits gets missed if the technician only inspects visible runs. Hidden leaks waste airflow and pressurize wall cavities. Our camera inspection finds these dead legs before we seal the active system, so you’re not heating empty space behind plaster.
- Condensation damage from Lake Michigan humidity attacks uninsulated metal ducts in Kenwood’s basements and crawl spaces. The moisture rusts metal, loosens tape, and promotes mold. We insulate and seal simultaneously, addressing both the symptom and the cause.

FAQs - Duct Repair & Sealing in Kenwood
Duct tape fails because it was never designed for heating ducts, and on Kenwood’s old galvanized metal, the adhesive breaks down faster from temperature cycling and surface oxidation. The tape dries, cracks, and peels within months, especially on the rust-speckled metal common in 1920s-1940s retrofits. We remove failed tape entirely, clean the metal with wire brushes, and seal with mastic and fiberglass mesh rated for 200-plus degrees. For a permanent fix on your Kenwood home’s metal ducts, call (877) 502-3903 for a free inspection.
Yes, we can access and seal many hidden duct runs using existing register openings, basement connections, and small strategic access points rather than demolishing historic plaster. For the 1910 Colonial Revival on Blackstone Avenue we recently worked on, we sealed a leaking metal trunk line where a previous contractor had connected flex duct to an abandoned steam riser. Using mastic and fiberglass mesh, we patched the joint and insulated the exposed section to prevent condensation in the humid Chicago summers. Camera verification confirmed the seal held. Call us to discuss your specific layout.
Rattling flex ducts usually indicate loose supports, improper sag, or a blower motor vibrating against an unsupported run; most cases are repairable without full replacement. We inspect the supports, tighten connections, and add proper hangers where the original installation skimped. If the flex itself is torn or crushed, we replace the damaged section. Most Kenwood Dryer Vent Cleaning and flex duct repairs in Kenwood condos run $240-$420. Call (877) 502-3903 and we’ll diagnose it in person.
We use foil-faced fiberglass wrap or rigid board insulation rated for the temperature extremes of Chicago attics, sealing all seams with mastic to prevent moisture infiltration. In Kenwood’s older homes, we frequently find original metal ducts with no insulation at all, or degraded asbestos-wrap remnants that require careful handling. We install new insulation that meets current Chicago energy code while respecting your home’s historic character. Full attic duct insulation in Kenwood typically costs $450-$780. Call for an exact quote.
The best method is removing the register, cleaning the boot-to-duct joint, applying mastic sealant, and reinstalling with a proper gasket; on historic plaster walls, we also seal the gap between the boot and the wall opening with fire-rated caulk. Register boot sealing in Kenwood homes runs $150-$280 per boot, with discounts for multiple units. This stops the conditioned air from leaking into your wall cavities. Call (877) 502-3903 to schedule.
