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.

We’ve been working in Manor long enough to recognize the pattern. A homeowner calls about weak airflow in a bedroom, or a chalky smell when the AC starts, or utility bills that climbed for no clear reason. The house was built in 2012, 2016, maybe 2020. The ducts should be fine. They’re not. Manor’s building boom left a specific problem in its wake, and our Duct Repair & Sealing team has documented it in hundreds of homes across the city.
Why CleanRun Air Duct Cleaning Round Rock Is Manor’s Preferred Duct Repair & Sealing Company
CleanRun has served the Austin metro since 2013, and Manor has been a core part of our route for years. We’ve completed repairs in Shadowglen, along FM 973, and throughout the subdivisions east of downtown. Our crews know the difference between a 2014 build with original flex duct and a 2019 build that may already have warranty-grade issues. That local pattern recognition matters when we’re diagnosing whether your problem is debris accumulation, seal failure, or crushed ductwork from original installation.
Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We identify our techs by name before arrival, not by truck number. The written price you receive is the price you pay - Haven Standard Clause 1, no exceptions. And every job concludes with a Documented Photo Record of every duct run, delivered to you as a standard deliverable, not an upsell.
Our 365-Day Done Right Promise applies in Manor exactly as it does everywhere else we work. If the repair fails, we make it right. That’s a written guarantee, not a policy that disappears when you call.
Our Duct Repair & Sealing Services in Manor

Duct Sealing
Most Manor homes built between 2010 and 2020 were sealed with builder-grade mastic or foil tape at the flex duct collars. That tape has a functional lifespan of roughly 8-12 years in Central Texas attic heat. We’re now in that window. Our duct sealing service removes the failing material and applies fresh mastic sealant (a thick, fiber-reinforced paste that hardens into a permanent airtight bond) at every connection point. We pressure-test the system afterward to verify the seal.

Flex Duct Repair
Flex duct - the ribbed, insulated tubing that carries conditioned air from your plenum (the main distribution box) to each room - is the standard in Manor tract homes. It’s also fragile. We’ve found crushed flex runs in attics across Shadowglen and newer subdivisions near US-290, often caused by storage placement or original installation where the duct was pulled too tight around a framing member. Our flex duct repair replaces damaged sections with new insulated flex, supported properly to prevent sagging or kinking.

Metal Duct Repair
Some Manor homes, particularly custom builds and certain phases of Shadowglen, use galvanized metal ductwork for main trunk lines. Metal ducts don’t tear like flex, but they do rust at seams and can separate at joints. We repair metal duct with proper mechanical fasteners and sealant rated for metal-to-metal contact, not the foil tape that will fail in two seasons.

Duct Insulation
Manor attics hit 140°F in July. Any duct without intact insulation is dumping cooled air into that heat before it reaches your register (the vent cover in your room). We replace degraded insulation with fresh fiberglass wrap or closed-cell insulation, depending on the application, and seal the vapor barrier to prevent condensation.

Mastic Sealant Application
Mastic isn’t tape. It’s a brush-applied compound that fills gaps and hardens into a flexible, permanent seal. We apply it at every collar, elbow, and seam in your system. In Manor’s newer homes, this is often the first time the ducts have been properly sealed since the original builder’s rushed application.

Air Leak Repair
Air leaks in Manor homes typically show up as hot spots in summer, cold spots in winter, or dust that reappears within days of cleaning. We locate leaks with pressure testing and visual inspection, then repair with appropriate materials - never a quick tape patch that will fail before the next cedar pollen season.

Common Duct Repair & Sealing Problems We See in Manor Homes

- Builder-grade tape failure at flex duct collars. The foil tape applied during Manor’s 2010s construction rush degrades in attic heat. We’re now seeing separation at 8-12 years - right on schedule. Homeowners notice it as weak airflow, dust, or a persistent attic smell.
- Construction debris embedded in flex duct corrugations. Manor’s active subdivision grading during the building boom drove caliche limestone dust and drywall particulate into ductwork before first occupancy. That debris doesn’t leave on its own. It compresses into the ribbed interior of flex duct, permanently reducing diameter and airflow.
- Crushed or kinked flex runs from attic storage or poor original support. A 6-inch flex duct crushed to 4 inches delivers roughly half the designed airflow. We find this in attics where homeowners stored holiday decorations, or where the original installer ran duct across a framing member without proper support.
- Pollen infiltration through poorly sealed connections during cedar season. Manor’s January mountain cedar (Ashe juniper) pollen is among the most intense allergen events in the United States. Poorly sealed duct connections pull that pollen into the system continuously, then distribute it through every register. Sealing the system is the fix, not another filter change.

FAQs - Duct Repair & Sealing in Manor

Because 2015 falls squarely in Manor’s builder-grade flex duct failure window. The foil tape and rushed mastic application used during the 2010s construction boom has a functional lifespan of 8-12 years in Central Texas attic heat. Your ducts aren’t old; the sealing material is simply expiring on schedule. We see this pattern throughout Shadowglen and subdivisions near FM 973. Call (737) 259-5752 for a camera inspection and written estimate.
Yes, if your home was occupied while adjacent lots were still being graded and framed. Manor’s rapid growth meant many homeowners moved into houses surrounded by active construction. HVAC systems running during that phase pulled caliche limestone dust, drywall particulate, and other construction debris directly into the ductwork. That material embeds in flex duct corrugations and remains there permanently without physical agitation and negative-pressure extraction. It’s a repair and cleaning issue, not something that resolves with time.
We start with a camera inspection of your supply and return ducts, then deliver a written scope and price before any work begins. For a typical Manor tract home, we remove failing tape and mastic at all flex duct collars, apply fresh mastic sealant, replace any crushed or damaged flex runs, and pressure-test the system to verify airtightness. The visit concludes with a Documented Photo Record of every run, before and after, delivered to you as part of the standard job record. Most visits take 3-5 hours. Call (737) 259-5752 to schedule.
Manor’s January mountain cedar (Ashe juniper) pollen is among the most intense allergen events in the United States. If your duct connections are poorly sealed, your HVAC system pulls that pollen continuously from the attic or wall cavities, then distributes it through every register. A sealed system with intact mastic at every joint is the only effective defense. Filter changes help, but they can’t compensate for an unsealed duct system pulling unfiltered attic air. We see the strongest demand for sealing visits in February and March, right after peak cedar season.
Nearly always. The vast majority of duct leaks in Manor’s slab-on-grade tract homes occur at accessible attic connections - the collars where flex duct meets the plenum or where branch lines split. We work from the attic, not from inside your walls. Only in rare cases of metal duct failure inside a wall cavity would access be more invasive, and we would note that specifically in your written scope and price before any work began. Call (737) 259-5752 to discuss your home’s layout.
