Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Duct Repair & Sealing Across Colleyville
Duct repair and sealing in Colleyville typically costs $180-$650 per system depending on whether the job involves spot sealing with mastic, flex-duct replacement, or full-system restoration. Most Colleyville homes need one to three systems addressed, and our crews complete standard sealing jobs in a single scheduled day. Call (817) 520-8797 for a written estimate before any work starts.
We dispatch to Colleyville from our Dallas-Fort Worth office, and our technicians know the difference between a 1990s custom build off Glade Road and a newer estate near Colleyville Boulevard. That matters because the ductwork in those homes fails differently. Our Duct Repair & Sealing team carries per-system pricing, camera inspection gear, and the documentation tools to show you what we found - not just tell you.
Why CleanRun Air Duct Cleaning Fort Worth Is Colleyville’s Preferred Duct Repair & Sealing Company
We’ve served Colleyville since adding the city to our route schedule in 2013, and the pattern is consistent: homeowners here research before calling, ask about equipment brands, and want the photo record. We deliver all three. Our 365-Day Done Right Promise is backed in writing on every job, not offered as a verbal courtesy.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The license number is published on this page, not buried in a footer. Every estimate is free, every price is written before work begins, and every job concludes with a Documented Photo Record of every duct run.
Colleyville’s concentration of large custom homes means longer service times and more complex system layouts than typical suburban jobs. We quote per system, not per vent, so a 6,000 square foot home with three air handlers gets three separate written scopes - not a single vague number that balloons once the crew is inside.
Our Duct Repair & Sealing Services in Colleyville

Duct Sealing
Leaky ducts pull attic air, pollen, and in Colleyville’s case, jet-exhaust particulate into your supply stream. We seal metal trunk lines and flex-duct joints with mastic sealant rated for North Texas thermal cycling, then verify with negative-pressure testing. A typical duct sealing job in Colleyville runs $280-$450 per system for homes under 4,500 square feet, and $400-$650 for larger estates with extended branch runs.

Flex Duct Repair
Colleyville’s 1990s-2000s custom homes relied heavily on flex duct for long branch runs - 150 linear feet or more per system in many houses near Cheek-Sparger Road and John McCain Road. That liner degrades after 20-30 years, shedding fibers and creating leaks where carbon-laden debris has accumulated. We replace degraded sections with Guardsman flex-duct products and seal all joints with mastic. Spot repairs run $180-$340; full branch-run replacement on a single system ranges $450-$890.

Metal Duct Repair
Metal trunk lines in Colleyville homes crack at elbows and seams from decades of expansion and contraction through 100-degree summers and hard freezes. We patch or replace damaged sections, then coat joints with mastic sealant. Metal repair typically runs $220-$480 per location, depending on accessibility and whether the trunk runs through finished ceiling space.

Mastic Sealant Application
Mastic is the standard for durable duct sealing - not tape, which fails. We brush-apply mastic to every joint, seam, and penetration after cleaning, then allow proper cure time before system restart. This is included in our standard duct sealing scope, not sold as an add-on. The material we use is rated for the thermal stress of attics that hit 140°F in August.

Duct Insulation
Uninsulated or degraded duct wrap in Colleyville attics wastes cooling capacity through eight-month summers. We install fresh insulation on repaired or sealed runs, typically $3-$5 per linear foot depending on R-value and accessibility.

AfterTrusted Brands We Service in Colleyville
Our equipment roster includes Rotobrush agitation systems, Nikro negative-pressure extractors, and Honeywell media filters - brands customers can look up independently. We stock Guardsman flex-duct repair materials on every Colleyville truck, so most flex-duct jobs don’t wait for parts. Technicians also carry mastic sealant rated for the temperature swings specific to unconditioned North Texas attics. If your system uses Aprilaire or Abatement Technologies components, we service those too.
Common Duct Repair & Sealing Problems We See in Colleyville Homes

- Carbon-laden film on supply registers near DFW flight paths. Homes on the Cheek-Sparger Road and John McCain Road corridors regularly develop a dark, sooty coating that homeowners mistake for mold. Our cameras show it’s fine particulate from aircraft combustion exhaust, drawn through fresh-air intakes and envelope gaps. Sealing the duct system and filtering the intake air stops the re-entrainment.
- Flex-duct liner degradation in 1990s-2000s custom homes. Those long branch runs - 150+ feet per system in 4,000+ square foot homes - reach end-of-life right about now. The liner cracks, sags at elbows, and sheds fiberglass into the airstream while leaking conditioned air into the attic.
- Multi-zone systems sealed as single units. A Colleyville home with three air handlers and zone dampers needs three separate inspection and sealing scopes. Miss the leaks at individual zone takeoffs and you’re paying to cool your attic.
- Mastic joints cracked from thermal cycling. North Texas attics swing from below freezing to above 130°F. Previous sealing work loosens at trunk-line elbows. We find this constantly in Colleyville homes that had “duct cleaning” from coupon services that never inspected the seams.
Pricing for Duct Repair & Sealing in Colleyville, TX
We publish ranges because Haven Standard Clause 1 requires a written price before any work starts. Here is what duct repair and sealing costs in Colleyville’s market:
| Service | Typical Range (per system) |
|---|---|
| Spot duct sealing with mastic | $180-$340 |
| Full-system duct sealing | $280-$650 |
| Flex-duct spot repair | $180-$340 |
| Flex-duct branch-run replacement | $450-$890 |
| Metal duct repair (per location) | $220-$480 |
| Duct insulation (per linear foot) | $3-$5 |
Two factors push Colleyville jobs toward the higher end: home size (more square footage means more ductwork) and system count. A 3,500 square foot home with one system sits at the low end. A 6,500 square foot home near Glade Road with three systems and 150-foot runs per handler requires three separate scopes. We quote each system individually so you see exactly what you’re paying for. Free estimates. Written price before work begins. No per-vent pricing, no coupon bait.

FAQs - Duct Repair & Sealing in Colleyville

It’s usually not mold. Homes beneath DFW’s runway 36R/18L approach corridors - particularly near Cheek-Sparger Road and John McCain Road - draw aircraft combustion particulate through fresh-air intakes and envelope infiltration. The carbon-laden PM2.5 deposits as a dark, sooty film on supply registers and inner duct walls. We verify this with camera inspection, then seal the duct system to reduce re-entrainment and upgrade intake filtration where appropriate. Call (817) 520-8797 for a free inspection and written estimate.
Yes. We quote and invoice per system, not per vent or per square foot. Each air handler and its associated ductwork is a separate scope of work with its own written price, camera inspection, and photo record. A home with three systems gets three separate documented reports. This prevents the common bait-and-switch where a single low quote balloons once the crew discovers the complexity. Every system gets its own Haven Standard Clause 1 written price before work starts.
You receive a Documented Photo Record of every duct run, before and after, as a standard deliverable on every job. We photograph each branch takeoff, elbow, and sealed joint. You also get the written scope stating what was sealed and with what material. The 365-Day Done Right Promise means if a sealed joint fails, we return and make it right - backed in writing, not subject to manager approval. This documentation practice has been standard on every CleanRun job since 2013.
Replace if the liner is degraded or shedding fibers; repair isolated damage if the liner is intact. We determine this with camera inspection, not guesswork. Colleyville’s 1990s-2000s custom homes with 150+ foot flex-duct runs are at the age where liner degradation accelerates, especially in branches near DFW flight paths where carbon particulate has accumulated for decades. We show you the camera footage, quote both options in writing, and let you decide. Free second opinion on any competitor’s written estimate.
It means the particulate load is heavier and more chemically complex, which accelerates buildup on duct surfaces and can degrade seals faster - but “more often” depends on your home’s envelope condition and filtration. The critical difference in Colleyville is that unsealed ducts pull this exhaust-laden air into your supply stream continuously. Proper sealing with mastic, verified under negative pressure, breaks that pathway. Homes a mile north of the flight path don’t face this same source. We assess your specific situation with camera inspection and negative-pressure testing, then quote sealing scope in writing. Call (817) 520-8797.
Ready for a written estimate? Call (817) 520-8797. We’ll schedule a camera inspection, show you what’s inside your ducts, and deliver a per-system price before any work begins. Every job includes the Documented Photo Record and the 365-Day Done Right Promise.
