Why CleanRun Air Duct Cleaning Leander Is Brushy Creek’s Preferred Duct Repair & Sealing Company

We’ve been documenting the inside of Brushy Creek ductwork since 2013, and the photo records tell a consistent story. Homes here built during the 1990s and 2000s suburban boom, particularly in neighborhoods like The Ranch at Brushy Creek, Brushy Creek North, and Fern Bluff, arrived with builder-grade flex duct in unconditioned attics. Those systems are now old enough that we’re regularly called in after a cleaning reveals disconnected runs, crushed elbows, or mastic that has dried and cracked after fifteen summers of 130°F attic heat.

Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we identify each crew member by name before arrival. Every Brushy Creek job starts with a written price under Haven Standard Clause 1, concludes with a Documented Photo Record of every duct run, and carries our 365-Day Done Right Promise in writing. We’ve served over 52,000 homes with this same protocol, and we offer a Free Second Opinion on any competitor’s written estimate, no cost, no obligation.

Our Duct Repair & Sealing Services in Brushy Creek

Flex Duct Repair

Flex duct repair is what we find ourselves doing most often in Brushy Creek. The inner liner of flex duct, the plastic sleeve that actually carries air, degrades after years in local attics that routinely hit 130-150°F from April through October. We see delamination, where the liner separates from the insulation jacket, and we see crushed sections at elbows where the original install left too tight a bend. Our crew cuts out the damaged section, installs new insulated flex with proper support straps, and seals every joint with mastic, not tape alone. In the Ranch at Brushy Creek, a two-story built in 2001 had a supply run in the attic that had collapsed at an elbow, so the master bedroom got almost no air while the bonus room roasted. We pulled a camera inspection on the flex run, found a disconnected joint and crushed inner liner near the plenum, cut out the bad section, and re-sealed with mastic and new insulated flex; the homeowner said the upstairs finally held temperature evenly for the first time in years.

Duct Sealing

Duct sealing in Brushy Creek is often the critical step that cleaning alone can’t fix. Return plenums and filter boxes in this cedar corridor collect fine yellow-green Ashe juniper pollen during December through February, but the deeper problem is the gaps and loose joints that let that pollen, plus attic air and insulation fibers, bypass the filter entirely. We seal supply and return plenums, register boots, and longitudinal seams with mastic sealant, then pressure-test to verify the seal. A typical Brushy Creek duct sealing job runs $340-$620 depending on system size and accessibility.

Metal Duct Repair

Metal ductwork in Brushy Creek appears mainly in older sections of Fern Bluff and in custom builds that used galvanized trunk lines with flex branches. We repair separated longitudinal seams, replace corroded sections, and reseal with mastic and mechanical fasteners. Metal duct doesn’t degrade from heat the way flex does, but the joints and seams fail from thermal expansion cycling, and we find that Brushy Creek’s extreme attic temperature swings, 150°F in summer to near-freezing in winter, accelerate that fatigue.

Duct Insulation

Duct insulation replacement becomes necessary when the fiberglass jacket on flex duct has compressed or gotten wet from condensation or roof leaks. In Brushy Creek’s humid cooling season, unconditioned attic air hitting cold supply ducts creates condensation that soaks insulation, reducing R-value and creating mold conditions. We replace compromised insulation with new vapor-barrier-wrapped material and verify with thermal imaging where appropriate.

Mastic Sealant Application

Mastic sealant is our standard for every Brushy Creek sealing job, not a tape-and-pray approach. We brush or trowel water-based mastic onto every joint, seam, and penetration, building a flexible, durable seal that outlasts foil tape by years. Mastic remains slightly pliable, so it accommodates the thermal expansion that destroys rigid seals in local attic conditions. A typical mastic sealing pass on a full Brushy Creek system takes 2-3 hours and is included in our duct sealing pricing.

Common Duct Repair & Sealing Problems We See in Brushy Creek Homes

• Flex duct inner liner delamination from sustained attic heat. The plastic air barrier inside flex duct separates from the fiberglass insulation after years at 130-150°F, creating a duct that looks intact from outside but leaks air through its entire length. We find this with camera inspection, then replace the run.
• Disconnected joints behind drywall chases. Original builder installs in 1990s-2000s Brushy Creek tract homes often buried flex connections in soffits or chase walls with no access panel. The joint works loose from thermal cycling, and the homeowner only notices when a room stops getting air. We locate the break with a camera, then cut minimal access to repair and seal.
• Return filter boxes coated in cedar pollen residue. During January cedar season, fine Ashe juniper pollen bypasses clogged filters and coats the interior of return plenums. This residue becomes a reservoir that re-releases allergens through spring, and it indicates gaps in the return path that need sealing, not just cleaning.
• Crushed or kinked flex at attic elbows. Tight turns in original installs, often where ducts round fireplace chases or beam pockets, collapse the inner liner over years. The duct appears to deliver air but at severely reduced volume, creating the hot-room-cold-room complaints we hear from Brushy Creek two-story owners.
