We’ve been driving to Irving from our Houston headquarters for over 42 years, and we know the difference between a Las Colinas condo built in 1989 and a slab-on-grade ranch off Story Road from 1965. That matters because the duct problems those two homes develop are completely different, and fixing them right means recognizing which is which before a single tool comes out of the van. Our Duct Repair & Sealing team carries the equipment to handle both: mastic sealant and mechanical fasteners for separated metal boots, and full flex duct replacement for collapsed runs in attic chases.
Irving sits on some of the most aggressive expansive clay soil in North Texas. That black gumbo shrinks and swells with every rain and drought cycle, and it’s been doing that since your home’s foundation was poured. The result? Duct connections that were tight in 1970 are now pulling loose, drawing attic air into your living space and sending your conditioned air into the wall cavities. We see it weekly in east Irving ZIP codes 75060, 75061, and 75062.
Why Bellows Air Duct & Vent Co. of Texas Is Irving’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in Irving on showing up, scoping the problem with a camera before we quote, and standing behind the work for 90 days in writing. No paperwork, no arguing. If it’s not right, we make it right.
Our technicians are background-checked and uniformed, and they answer to a live person at our office 24 hours a day. Not a voicemail tree. Not an app. A real person who can dispatch a crew to Irving today if that’s what you need.
We know the local housing stock because we’ve worked on it for decades. The post-war brick ranches with original galvanized ductwork. The 1980s Las Colinas townhomes with flex duct that’s now brittle from twenty years of 100°F summers. The mid-rise conversions off O’Connor Road with multi-zone systems that need commercial-grade attention. That local knowledge means we diagnose faster and fix it right the first time.
Our pricing is disclosed upfront, before we lift a single tool. The number we give you on the phone is the number on the invoice. No bait coupons, no price changes at the door. That’s been our promise since Wade Kellerman founded Bellows in 1984, and it’s not changing.
Our Duct Repair & Sealing Services in Irving
Duct Sealing
Most Irving homes lose 20-30% of conditioned air through leaks at joints, seams, and connections. In older neighborhoods like Barton Estates or the original Las Colinas subdivisions, that number can climb higher. We use professional-grade mastic sealant and metal-backed tape, not the cheap foil tape that peels off in a hot attic. A typical duct sealing job in Irving runs $280-$450 for a single-system home. We camera-inspect before and after, so you see the difference.
Flex Duct Repair
Flex duct is common in Las Colinas condos and townhomes built from the mid-1980s through the late 1990s. After thirty years of North Texas heat, the inner liner cracks, the insulation compresses, and the wire helix kinks where it bends through tight chases. We replace damaged sections with new, properly sized flex duct and secure it with mechanical fasteners, not just zip ties. Flex duct repair in Irving typically costs $180-$340 per run, depending on attic access and length.
Metal Duct Repair
East Irving’s 1960s and 1970s ranch homes often have original galvanized steel ductwork. It corrodes at the joints. It separates where the clay soil has shifted the slab. We’ve found supply plenums in homes off Shady Grove Road that were leaking so badly the master bedroom got almost no airflow in July. We repair metal duct with custom-fabricated patches, proper mechanical connections, and mastic sealant. Metal duct repair in Irving runs $320-$580, with larger jobs involving multiple disconnected runs toward the higher end.
Air Leak Repair
Air leaks are the hidden problem we find most often in Irving. Not the obvious disconnected trunk line, but the slow, steady pull of attic air through a gap that’s opened where the duct boot meets the ceiling drywall. That leak doesn’t just waste money. It pulls in insulation fibers, pollen, and whatever else is in your attic. In an east Irving ranch on a slab foundation, we arrived for a routine cleaning but scoped the supply plenum first-good thing: the 1970s flex duct boot had pulled loose by 1.5 inches from the shifted clay soil. We used mastic sealant and mechanical fasteners to reattach and seal the boot, preventing insulation fibers from being sucked into the living room air supply.
Duct Insulation
When we repair or replace duct in an unconditioned Irving attic, we always check the insulation. R-6 is the minimum for our climate, and many older homes have R-4 or less, or insulation that’s fallen away from the duct entirely. Re-insulating after repair keeps the air you paid to cool actually cool when it reaches your vents. Duct insulation in Irving typically adds $150-$280 to a repair job.

Trusted Brands We Service in Irving
We stock parts and use equipment from Rotobrush, Honeywell, and Aprilaire, the same brands serious HVAC contractors specify for the Texas market. That means faster turnaround for Irving customers.

For a standard repair, most Irving jobs are completed in a single visit.
Common Duct Repair & Sealing Problems We See in Irving Homes
- Separated flex duct boots from foundation shifting. After years of foundation shifting from expansive clay soil, flex duct boots separate from the supply plenum, drawing attic insulation and debris into the living space even during cleaning. We scope every connection before we clean.
- Corroded galvanized joints in original 1960s ductwork. Original galvanized ductwork from the 1960s has corroded at joints, creating large leaks that drastically reduce system efficiency and allow unconditioned attic air to mix in. We patch or replace sections as needed.
- Hidden kinks and holes in aging Las Colinas flex duct. Aging flex duct in Las Colinas condos (built 1980s-1990s) develops hidden kinks and holes from years of heavy cooling-season use, which standard cleaning won’t address without repair. We locate and replace damaged runs.
- Disconnected returns pulling in garage or attic air. In slab homes where the return chase runs through the garage, we’ve found separated connections that pull in car exhaust and attic heat. That’s a health and efficiency problem, and we seal it properly.
Pricing for Duct Repair & Sealing in Irving, TX
Here’s what duct repair and sealing costs in Irving’s market:
| Service | Typical Range in Irving |
|---|---|
| Duct sealing (mastic, joints, seams) | $280-$450 |
| Flex duct repair/replacement (per run) | $180-$340 |
| Metal duct repair (patching, reconnection) | $320-$580 |
| Air leak repair (boot reattachment, sealing) | $220-$380 |
| Duct insulation (add-on to repair) | $150-$280 |
What moves you within these ranges? Attic access matters. A walk-up attic with a permanent ladder takes less time than a hatch in a closet. The extent of separation matters. One loose boot is a different job than four disconnected returns. And the age of the system matters. Original 1960s galvanized duct sometimes needs more extensive work than 1990s flex.
We offer $50 off any repair over $250, and we always provide a free second opinion on any written estimate you’ve received. Our $89 Seasonal Tune-Up can catch duct problems before they become expensive repairs. Seniors and veterans receive a permanent 5% discount.

FAQs - Duct Repair & Sealing in Irving
Yes, in most cases we can repair and seal original galvanized ductwork without full replacement. We patch corroded joints, reconnect separated sections with mechanical fasteners, and seal everything with mastic. Full replacement is only necessary when the metal is too deteriorated to hold a seal, which we determine with camera inspection. Call (866) 347-2063 for a free assessment.
Yes, we repair flex duct in Las Colinas condos and townhomes, including runs hidden in ceiling chases and wall cavities. We use camera equipment to locate kinks, holes, and collapsed sections without unnecessary drywall damage. Most Las Colinas flex duct repairs run $180-$340 per run. Call (866) 347-2063 to schedule.
Disconnected duct boots are a common cause of persistent dust after cleaning, especially in east Irving slab homes where clay soil movement has pulled boots loose. If the boot is separated from the plenum, cleaning just redistributes attic debris into your living space. We scope every connection before cleaning to prevent this. Call (866) 347-2063 and we’ll check it with a camera.
Yes, we handle residential duct repair throughout Irving’s neighborhoods and commercial work in the Las Colinas Urban Center, including multi-zone HVAC systems in office towers and hotel complexes. Commercial pricing depends on system size and access. Call (866) 347-2063 to discuss your building’s needs.
Irving follows the 2021 International Mechanical Code with Texas amendments, which requires duct sealants to meet UL 181 standards for smoke and flame spread. We use only code-compliant mastic and tape. For homeowners, the practical implication is that cheap hardware-store foil tape won’t pass inspection and won’t hold up in a hot Irving attic. We use professional-grade materials on every job. Call (866) 347-2063 with specific questions.
