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 Cedar Park
Most duct repair and sealing jobs in Cedar Park run $280-$650 for a standard single-system home, and we can usually schedule within 3-5 business days. Our crews are already working the RM 1431 and RM 2243 corridors weekly, so western Cedar Park neighborhoods like Ranch at Brushy Creek and Buttercup Creek don’t wait for a tech to drive up from Austin.
We’ve been dispatching to Cedar Park from our Austin office since 2013, and the route is familiar enough that our technicians know which master-planned subdivisions have the long attic flex runs typical of 2000s-2020s slab-on-grade construction. That matters because Cedar Park’s housing stock is unusually uniform, and the failure modes we see here - flex duct collars popping at the air handler, mastic sealant drying out in 130°F attic heat, cedar pollen loading return systems every February - aren’t random. They’re predictable. Call (737) 243-9544 for a written estimate before any work starts.
Why CleanRun Air Duct Cleaning Austin Is Cedar Park’s Preferred Duct Repair & Sealing Company
CleanRun has completed duct repair and sealing work in more than 2,800 Cedar Park homes since 2013, and the documented photo record from every job - before and after, inside every duct run - is available for customers to review. That archive is how we know that flex duct collar separation at the attic air handler is the single most common repair call we get from the Avery Ranch and Ranch at Brushy Creek areas.
Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. Tomas Reyes, who leads CleanRun, requires that every Cedar Park job start with a written price delivered before a single panel comes off - no exceptions, no “call for a quote.” The 365-Day Done Right Promise applies in Cedar Park exactly as it does everywhere else we work: if the repair or seal isn’t right, we make it right, backed in writing on every invoice.
Response time to Cedar Park is typically 3-5 business days for standard duct sealing and flex duct repair, with scheduling coordinated from our Austin office. We’re not guessing at your system layout. Most Cedar Park homes built between 2000 and 2020 share the same basic architecture: single central air handler in the attic, long flex duct trunk lines to perimeter rooms, and return grilles pulling air from central hallways. Our crews have worked that configuration hundreds of times.
Our Duct Repair & Sealing Services in Cedar Park

Duct Sealing
Duct sealing in Cedar Park addresses the conditioned air leaking into your attic through gaps at plenum connections, register boots, and seam joints. In the 5-15 year-old homes common in Buttercup Creek and Avery Ranch, we regularly find that original mastic sealant has dried and cracked after summers of 130°F+ attic exposure. Our crew removes the degraded material, reseals with fresh mastic, and pressure-tests the system to confirm the leakage rate has dropped. A typical duct sealing job in Cedar Park runs $280-$450 for a single-system home.

Flex Duct Repair
Flex duct repair is our most frequent Cedar Park service call. The plastic inner liner and insulation wrap on flex ducts degrade faster in hot attics, and the adhesive at collar connections softens and fails. In western Cedar Park neighborhoods along RM 1431, where homes sit closer to undeveloped Hill Country scrub, we also see flex ducts damaged by rodent activity and by filters loading so heavily with cedar pollen that the blower motor over-amps and vibrates ductwork loose. We replace damaged flex sections, reconnect collars with mechanical fasteners plus mastic, and insulate to R-6 or better. Typical flex duct repair in Cedar Park: $180-$380 per run.

Metal Duct Repair
Metal duct repair in Cedar Park is less common than flex work but critical when it arises. Older metal trunk lines in pre-2000 homes, and some custom builds in the Ranch at Brushy Creek area, can corrode at seams or separate at slip joints after years of thermal expansion. We patch small breaches with sheet metal and sealant, replace rotted sections, and reinforce connections. Metal duct repair in Cedar Park typically runs $320-$650 depending on accessibility and extent.

Duct Insulation
Duct insulation in Cedar Park addresses the energy loss and condensation problems that come from running 55°F supply air through ducts in 130°F attics. We see this most often in homes where original insulation has compressed, torn, or been disturbed by prior service work. Our crew wraps repaired or exposed ductwork with new fiberglass insulation and vapor barrier, sealed at seams. Duct insulation work in Cedar Park generally runs $200-$400 per duct run.

Mastic Sealant Application
Mastic sealant is the standard we apply on every Cedar Park duct sealing job - not tape alone, which degrades. We brush or trowel water-based mastic onto all seams, joints, and connections, then allow proper cure time before restoring system pressure. The mastic we use is rated for the temperature swings Cedar Park attics experience, and we document the application with photos included in your job record.

AfterTrusted Brands We Service in Cedar Park
CleanRun carries professional-grade equipment from Nikro, Honeywell, and Aprilaire on every Cedar Park job, and we stock common flex duct diameters, collar sizes, and mastic compounds locally so repairs aren’t delayed waiting on parts. Our negative-pressure extraction systems from Nikro and Abatement Technologies are the same units specified in commercial HVAC standards, and the Honeywell and Aprilaire media filters we can install after sealing work are rated for the fine particulate load Cedar Park’s cedar season produces. You can verify any of these brands independently - we name them specifically so you can.
Common Duct Repair & Sealing Problems We See in Cedar Park Homes

- Flex duct collars pop loose at the attic air handler after years of 130°F+ summer attic heat degrading the adhesive. This is common in 2000s-2020s slab-on-grade tract builds with long single-trunk flex runs, which describes most of Cedar Park’s housing stock. The separation leaks conditioned air into the attic and pulls unfiltered attic air into the return.
- Original-construction drywall dust and sawdust from fast master-planned subdivision builds gets sealed into the supply and return ducts and never removed. Many Cedar Park homes in the 5-15 year range have never had duct cleaning since construction. That debris re-entrains every time the blower motor starts, loading filters prematurely and obscuring leak points we’d otherwise seal.
- Rural-adjacent homes near the RM 1431/RM 2243 cedar scrub pull fine Ashe juniper pollen so heavily that cheap low-MERV filters load within weeks. Once the filter is clogged, air bypasses the frame and enters every duct seam, collar gap, and plenum joint - exactly the leaks we’d seal in a standard duct sealing job, but now they’re actively importing pollen.
- Long attic flex runs in Cedar Park’s typical single-trunk designs sag between supports, creating low points where condensation collects and insulation compresses. The sag also increases static pressure, forcing the blower motor to work harder and accelerating wear on the entire system.

FAQs - Duct Repair & Sealing in Cedar Park

Every 2-3 years for rural-adjacent Cedar Park properties, and annually if you heat with wood or have unpaved road dust loading the system. The Ashe juniper pollen alone, plus Hill Country dust from open land, creates a particulate burden that suburban Cedar Park homes 5 miles east don’t match. Call (737) 243-9544 and we’ll inspect your filter loading and duct integrity to set an interval specific to your property.
The adhesive at flex duct collars degrades after repeated exposure to 130°F+ attic heat, which is standard in Cedar Park from May through October. Once the adhesive fails, the mechanical stress of blower motor startup and shutdown finishes the separation. We repair with mechanical fasteners plus fresh mastic, not adhesive alone, and we document the repair with before-and-after photos.
Yes, measurably. The fine yellow-green Ashe juniper pollen that loads Cedar Park’s return systems every February-March is 20-30 microns and highly allergenic. Removing that accumulated load from duct interiors, plus sealing the leaks that reintroduce it, drops airborne particulate in the living space. We photograph the pollen accumulation before removal so you can see what was in the system.
Yes, especially for duct sealing. Construction debris sealed into ducts during fast master-planned builds in Avery Ranch, Ranch at Brushy Creek, and similar communities obscures leak points and loads filters prematurely. We find original drywall dust in roughly 60% of first-time cleanings in these neighborhoods. Cleaning first lets us seal properly, and the photo record shows you what was there.
Yes, we regularly repair and seal ductwork in detached workshops, garage HVAC additions, and guest house mini-split conversions in the western Cedar Park rural interface. The same written pricing and photo documentation apply. Access and materials may affect scheduling, so call (737) 243-9544 with your specific setup for an exact quote.
