Duct Repair & Sealing in Keller - We Measure the Leak Before We Quote

Fast, Reliable Duct Repair & Sealing Across Keller

Most Keller homes were built during the same 15-year window, and they’re all showing the same duct problems right now. If you’re noticing weak airflow upstairs, dust that returns within days of cleaning, or a blower motor that runs longer than it used to, the issue is probably in your attic ductwork, not your HVAC unit. Our Duct Repair & Sealing crews serve Keller from our Dallas-Fort Worth office, and we know the specific failure patterns in subdivisions like Saddlebrook Estates, Hidden Lakes, and the streets off Keller Parkway.

Why CleanRun Air Duct Cleaning Irving Is Keller’s Preferred Duct Repair & Sealing Company

We’ve been documenting every duct run we touch since 2013. That practice matters in Keller more than most places because of how this city was built, and it’s why our Keller Dryer Vent Cleaning service follows the same rigorous standards.

Keller’s residential explosion between roughly 1993 and 2008 means the vast majority of its housing stock is now 15-30 years old - precisely the age at which builder-grade flexible ductwork installed in Texas attic spaces begins to sag, micro-tear, and accumulate a decade or more of compacted debris. Because nearly the entire city was platted and built within this same narrow window, Keller has an unusually dense concentration of homes all hitting their first critical duct-cleaning milestone at the same time, a demand pattern that distinguishes it from older Fort Worth neighborhoods (different materials, already cycled through cleaning) or newer Northlake-era developments (ductwork still fresh).

Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We publish our license number on every page. Every job starts with a written price and ends with a Documented Photo Record of every duct run, delivered to you as a standard deliverable, not an upsell. The 365-Day Done Right Promise applies in writing on every Keller job. If it’s not right, we make it right.

We’re also Keller‘s direct answer to the $79 coupon model. That approach can’t fix a kinked flex duct run or seal a leaking plenum penetration. We use Rotobrush and Nikro professional-grade equipment, and we name those brands so you can verify what we’re bringing into your home before you agree to any price.

Our Duct Repair & Sealing Services in Keller

Flex Duct Repair

Keller’s large two-story tract homes, common in subdivisions near Keller Smithfield Road and along Davis Boulevard, use long flex duct runs routed through unconditioned attics. Summer temperatures in those attics routinely exceed 140°F, which accelerates liner degradation and bakes accumulated dust onto interior surfaces. Technicians working Keller’s older subdivisions consistently find that flex duct runs installed circa 1997-2006 have sagged and kinked where they cross attic joists or HVAC platforms, creating low-point debris traps that a standard vacuum wand cannot reach without physically repositioning the duct first - a labor step many companies skip, but one that local repeat customers in Keller’s older subdivisions have learned to specifically ask about. We repair or replace damaged flex sections, reposition runs for proper slope and airflow, and document the before and after.

Mastic Sealant Application

Air leaks around plenum penetrations and platform joints pull 140°F attic dust directly into your system, bypassing the filter entirely. This failure is especially common in Keller’s large two-story homes, where multiple return-air chases create more penetration points than smaller single-story stock. We seal every joint with mastic, a brush-applied sealant that outlasts tape in Texas attic conditions. Haven Standard Clause 1 requires the written price before work starts; Clause 2 requires the photo record after. Both apply to every mastic job we do in Keller.

Air Leak Repair

Unsealed return-air chases in Keller homes pull mountain cedar (Ashe juniper) pollen directly from the attic during January-February “cedar fever” events, some of the highest airborne pollen counts in the country. That pollen bakes onto duct interiors and spikes indoor-air-quality complaints each late winter. We pressure-test your duct system, locate leaks with smoke pencils and thermal checks, and repair them with sealed mechanical connections or mastic, depending on the location and access.

Metal Duct Repair

Some Keller homes, particularly earlier builds from the 1993-1997 period and certain custom construction near Bear Creek Parkway, used galvanized metal ductwork for main trunk lines. Metal ducts don’t sag like flex, but they do separate at seams and corrode at condensate collection points. We repair separated seams with mechanical drives and seal them with mastic, replacing sections where corrosion has compromised the wall.

Duct Insulation

When flex duct liner degrades in a 140°F Keller attic, the insulation value drops and condensation forms on cool-air supply runs. We replace damaged insulation with properly rated materials and verify R-value recovery with thermal imaging, included in the standard photo record.

Trusted Brands We Service in Keller

CleanRun crews arrive with professional-grade equipment from Rotobrush, Nikro, Honeywell, and Aprilaire - brands you can look up independently before we start. We don’t use shop vacs with extra hoses. For Keller’s specific conditions, the Rotobrush brush-and-vacuum system breaks up compacted drywall debris and baked-on pollen that negative-pressure extraction alone won’t move, while Nikro HEPA-filtered collection ensures what we pull out of your ducts doesn’t recirculate through your home. We stock common flex duct diameters and mastic quantities locally, so most Keller repairs don’t wait on parts.

Common Duct Repair & Sealing Problems We See in Keller Homes

• Builder handover dust: Drywall debris and construction dust from Keller’s 1997-2006 builds left in the supply and return ducts, clogging filters and loading the air handler before the first year is up. We regularly find this compacted at the first elbow in homes off Keller Parkway and around Hidden Lakes.
• Sagged flex duct at joist crossings: Runs that kink and create low-point debris traps in attic spaces where summer temperatures routinely exceed 140°F, accelerating liner degradation. The two-story floor plans common in Keller mean longer runs and more joist crossings than single-story stock.
• Cedar pollen intrusion through unsealed joints: January-February Ashe juniper pollen pulled into leaky return-air chases, baking onto interior duct surfaces and spiking indoor-air complaints. This is a Keller-specific problem; the DFW mountain cedar belt runs directly through this area.
• Mastic skipped at platform penetrations: Air leaks around the air handler and plenum that pull attic dust into the system instead of through the filter, a failure common in Keller’s large two-story tract homes where builders minimized labor on invisible attic work.
