We’ve worked in Colleyville long enough to know the difference between a 1992 build off Glade Road and a 2005 estate near Bransford Road. The ductwork tells the story. Homes here are bigger, the HVAC systems are more complex, and the conditions in those attics are harder on flex duct than most homeowners realize. That’s why we camera-inspect every system before we quote, and why we seal with mastic, not tape that’ll bake off in July.
Why Bellows Air Duct & Vent Co. of Texas Is Colleyville’s Preferred Duct Repair & Sealing Company
We’ve been serving Texas homeowners since 1984 - over 42 years - and Colleyville has been part of our route for decades. The homes here demand a different level of care than standard suburban construction. A 4,500-square-foot custom build with four zones and 200 linear feet of flex duct routed through a 140°F attic isn’t a job for quick-patch work.
Our technicians are background-checked, uniformed, and trained on the specific failure modes we see in Colleyville’s housing stock. They answer to a live person at our office, 24 hours a day. No voicemail, no app. When you call (866) 347-2063, someone picks up.
Our 90-Day Done Right Promise applies to every Colleyville job. If the seal doesn’t hold, if a connection fails, if the temperature balance is off - we come back at no charge. No paperwork to file, no argument. We stand behind it because we’ve stood behind our work for four decades.
We’re also the square-deal alternative to coupon bait-and-switch. Our price is our price. Disclosed before we lift a tool. The number on the phone is the number on the invoice.
Our Duct Repair & Sealing Services in Colleyville
Duct Sealing
Air leaks in Colleyville’s multi-zone systems waste 20-30% of conditioned air on average, and summer attic heat makes the problem worse. We seal every joint, transition, and penetration with professional-grade mastic sealant, then verify with camera inspection. In a custom estate near Bransford Road, we sealed and insulated 20-year-old metal duct trunks where jet exhaust particulates had accelerated corrosion at transition points. We applied mastic sealant and new flex duct sections, matching the original 12-inch R-6 insulation to maintain the homeowner’s zoned temperature precision. Duct sealing in Colleyville typically runs $1,200-$2,800 for whole-system work, or $250-$450 per zone for targeted repairs.

Flex Duct Repair
Colleyville’s 1990s-era flex duct is now 25-30 years old, and attic heat has baked the inner liners brittle. We see this constantly in homes off Glade Road and throughout the 76034 zip code. Our technicians inspect liner integrity with cameras before any repair - cleaning a compromised liner releases fiberglass particles into your living space, a failure mode that’s disproportionately common here. When we replace flex duct, we use R-6 or R-8 insulation to match or exceed original specs, and we secure every run with proper supports so it doesn’t sag and restrict airflow. Flex duct repair in Colleyville ranges from $350-$850 per run depending on length and attic access.

Metal Duct Repair
Original metal ductwork in Colleyville’s estate homes corrodes unevenly at transitions and seams, especially where ultrafine particulates from DFW flight corridors accumulate and recirculate. We cut out damaged sections, fabricate replacements to match, and seal with mastic for a permanent fix. Metal duct repair typically costs $400-$950 per section, including insulation restoration to prevent condensation and energy loss.

Duct Insulation Replacement
Summer attic temperatures of 140-150°F in Colleyville degrade duct insulation from the outside in. We replace compressed, moisture-damaged, or heat-brittled insulation with new R-6 or R-8 wraps, sealed at every seam. Proper insulation maintains the temperature precision your zoned system was designed for, and it prevents the condensation that leads to mold and metal corrosion. Insulation replacement runs $2-$4 per linear foot, with most Colleyville homes needing 150-300 feet of coverage.

Common Duct Repair & Sealing Problems We See in Colleyville Homes
- Brittle flex duct liners shedding fiberglass. Original 1990s flex duct in Colleyville’s estate homes has inner liners that crack and flake after decades in extreme attic heat. We camera-inspect every system before cleaning or sealing to catch this - repairing without checking risks blowing fiberglass particles through every vent.
- Multi-zone air leaks at attic connections. Long flex runs between zone dampers and trunk lines develop gaps at connection points, especially where tape adhesive has failed from repeated 140°F+ exposure. Mastic sealing restores airflow balance and stops the temperature swings between rooms.
- Metal duct corrosion from recirculated particulates. Colleyville’s position under DFW flight corridors means ultrafine jet exhaust particles cycle through HVAC systems continuously. These accumulate at metal transitions, accelerating corrosion hidden behind insulation until airflow drops or musty odors appear.
- Insulation compression and thermal bridging. Original R-6 insulation in 1990s builds has settled, torn, or been displaced by rodents and service work over 30 years. Bare metal duct in a 150°F attic loses cooling capacity fast, and your system runs longer to compensate.
Pricing for Duct Repair & Sealing in Colleyville, TX
We’re upfront about numbers because nobody likes a surprise on the invoice. Here’s what duct repair and sealing costs in Colleyville’s market:
| Service | Typical Range |
|---|---|
| Single-zone duct sealing (mastic) | $250 - $450 |
| Whole-system duct sealing | $1,200 - $2,800 |

| Metal duct repair (per section) | $400 - $950 |
| Duct insulation replacement | $2 - $4 per linear foot |
| Duct inspection with camera | $89 - $149 (waived with repair) |
Three things move the price: attic accessibility (tight truss spaces take longer), the linear footage of ductwork (Colleyville’s larger homes have more), and whether we find corroded metal that needs section replacement versus simple resealing. We inspect first, quote second, and start work third. No bait coupons, no price changes at the door.
We also honor our standing offers: $50 off any repair over $250, free second opinion on any written estimate, $89 seasonal tune-up, and a permanent 5% senior and veteran discount. Call (866) 347-2063 for your exact quote - estimates are free.

FAQs - Duct Repair & Sealing in Colleyville
Ultrafine jet exhaust particles accumulate in Colleyville homes at rates meaningfully higher than Keller or Southlake, then recirculate through HVAC systems and accelerate corrosion at metal duct transitions. We inspect for this damage specifically in Colleyville homes, and we seal with mastic rather than tape because particulate-laden airflow erodes standard adhesives faster. Call (866) 347-2063 if you’ve noticed musty odors or uneven cooling - we’ll camera-inspect and quote free.
Yes - the 4,000-6,500 square foot homes built from the late 1980s through mid-2000s have far more ductwork than standard construction, and 25-30 years of thermal cycling has loosened joints and degraded seals. Multi-zone systems with long flex runs are especially prone to attic leaks that waste conditioned air and create temperature imbalances between rooms. Whole-system sealing typically pays for itself in 2-4 years through reduced energy bills in these larger homes.
We match or exceed original R-values on every replacement - R-6 for standard flex duct, R-8 where code or system design requires it. In the Bransford Road job, we matched 12-inch R-6 insulation precisely to preserve the homeowner’s zoned temperature control. We don’t guess; we measure what’s there and replicate it with new material that meets current standards.
White or gray dust around supply vents, sudden allergy symptoms when the system runs, or a technician’s warning after previous cleaning are the three most common indicators. In Colleyville specifically, 1990s flex duct baked in 140-150°F attics develops brittle, shedding liners at rates we don’t see in newer suburbs. We camera-inspect before any work to confirm liner integrity - it’s a step some crews skip, and it matters here more than most places.
Yes - we cut out corroded sections, fabricate matching replacements, and seal with mastic for a permanent fix. Metal duct corrosion from recirculated particulates is a Colleyville-specific issue we encounter regularly, especially at trunk line transitions behind old insulation. Most metal repairs run $400-$950 per section and are completed in a single visit. Call (866) 347-2063 for a free inspection - we’ll show you the corrosion on camera before quoting any work.
