Why Bellows Air Duct & Vent Co. of Chicago Is Maywood’s Preferred Duct Repair & Sealing Company

We’ve been driving to Maywood for over four decades, long before the Eisenhower Expressway was the route it is today. Ray Dempsey started this company in 1984 on a simple principle: show the homeowner what’s broken, quote it honestly, and stand behind the fix. That hasn’t changed.

Our technicians are background-checked, uniformed, and carry the same Rotobrush and Nikro equipment that serious HVAC contractors specify. Every duct repair in Maywood gets camera-inspected before and after, so you see the corroded joint or the detached flex connection, not just take our word for it. Calls to our office are answered by a live person 24 hours a day, not an app or a voicemail tree. And our 90-Day Done Right Promise means if the seal doesn’t hold or the repair fails, we return at no charge with no paperwork to argue over.

Maywood homeowners tend to stay put. They know their houses, they know when something’s off, and they’ve usually already been burned by a low-bid contractor who disappeared. We don’t compete on coupons. We compete on never needing to be called back.

Our Duct Repair & Sealing Services in Maywood

Duct Sealing with Mastic Sealant

Maywood’s low-lying position in the Des Plaines River floodplain causes persistent ground moisture that accelerates joint corrosion in aging galvanized duct trunks, making mastic sealant repairs far more common here than in drier neighboring suburbs. We brush on professional-grade mastic sealant and reinforce with foil tape at every joint, seam, and register boot. The mastic remains flexible through Chicago’s brutal temperature swings, so it won’t crack like cheap tape jobs. On a bungalow near 5th Avenue and Washington Boulevard, our crew used mastic sealant and foil tape to reseal a split trunk joint corroded by past flood moisture; we also installed a Honeywell UV air purifier to address mold spores left behind after the water receded. Most mastic sealing jobs in Maywood run $180-$340 and are finished in two to three hours.

Duct Sealing with Mastic Sealant

Metal Duct Repair

Maywood’s housing stock is dominated by early-to-mid 20th century brick bungalows and two-flats, the majority built between the 1920s and 1940s, many with oversized, uninsulated galvanized trunk-and-branch duct systems converted from original gravity (octopus) furnaces. These large-diameter, aging metal runs accumulate decades of debris, are prone to joint separation, and present sealing challenges after cleaning that newer flex-duct systems do not. We cut out corroded sections, fabricate replacement trunk pieces on-site, and seal with mastic and mechanical fasteners. A full metal trunk repair in Maywood typically runs $400-$650, depending on accessibility and how many branch takeoffs need reworking.

Metal Duct Repair

Air Leak Repair

Corroded metal duct joints in older bungalows fail under seasonal humidity swings, causing air leaks that reduce HVAC efficiency and draw in attic dust. We pressurize the system, locate leaks with a smoke pencil, then seal each breach. The Chicago metro’s wide seasonal humidity swings already stress ductwork, but Maywood’s low-lying position in the Des Plaines River corridor means ambient ground moisture is persistently elevated in basements and crawl spaces, accelerating mold and dust-mite colonization inside duct systems compared to drier, upland suburbs on the same latitude. Air leak repair in Maywood generally falls between $220 and $450.

Air Leak Repair

Flex Duct Repair

Flex duct connections in crawl spaces detach due to ground moisture weakening the clamps, leading to pressurized air loss and condensation damage. We replace degraded flex, install new galvanized clamps, and support with proper hangers so the duct doesn’t sag back into the damp. Flex duct repair in Maywood typically costs $200-$380.

Flex Duct Repair

Duct Insulation

Uninsulated metal trunks in Maywood basements sweat heavily in summer, dripping onto floors and promoting mold. We wrap with formaldehyde-free fiberglass insulation and vapor barrier, sealed at every seam. Duct insulation jobs in Maywood run $300-$550 for a typical bungalow system.

Trusted Brands We Service in Maywood

We carry Rotobrush agitation tools and Nikro HEPA vacuums on every truck, and we stock Honeywell and Aprilaire air quality components for same-day installation when your duct repair reveals a deeper problem. Our Maywood customers don’t wait two weeks for a part. If your repair uncovers a failing UV light, a dead zone damper, or a humidifier pad choked with flood silt, we likely have the replacement on the van. That’s the difference between a duct company and a company that actually fixes houses.

Common Duct Repair & Sealing Problems We See in Maywood Homes

  • Corroded galvanized joints from floodplain moisture. Maywood sits in the Des Plaines River floodplain corridor and has experienced repeated flood events over the decades; many of the village’s older bungalows and two-flats have basement or ground-level ductwork that has been exposed to floodwater intrusion, making mold contamination and silty debris inside duct systems a far more common finding here than in the higher-elevation suburbs immediately to the east like River Forest or Oak Park. Air duct cleaning in Maywood routinely doubles as post-flood remediation work, a combination most neighboring communities rarely face at the same scale.
  • Detached flex ducts in damp crawl spaces. The persistent ground moisture weakens nylon cable ties and corrodes metal clamps, so flex connections separate and blow conditioned air into the dirt.
  • Post-flood silty debris blocking registers. Technicians working in Maywood’s western flood-zone blocks regularly pull register boots and find silty residue, waterline staining, or dried organic debris deep inside main trunks - evidence of past flood intrusion that homeowners, especially recent buyers, are often completely unaware of. Post-flood silty debris trapped in main trunks is often overlooked by homeowners, causing repeated blockages at registers and requiring aggressive vacuum extraction before any sealant can adhere.
  • Failed gravity-furnace conversions with oversized trunks. Those old octopus systems were never designed for forced air. The trunk diameter is too large, velocity drops, and dust settles in seams that were never meant to be sealed.

What Maywood Customers Say

Trusted by homeowners across Maywood and surrounding areas.

★★★★★

"Fair price and thorough work. They ran about an hour and a half past the estimated finish, so do not schedule anything tight after them."

Malik Hampton · Verified customer
★★★★★

"Found a disconnected run in the crawlspace while they were down there and told me about it rather than cleaning around it."

Gabriela Castillo · Verified customer
★★★★★

"They ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
