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.

AfterFast, Reliable Duct Repair & Sealing Across Wells Branch
Duct repair and sealing in Wells Branch typically costs $280-$750 for most residential jobs, with whole-system flex duct replacement running $1,800-$3,400 depending on home size and attic accessibility. Most Wells Branch homes need assessment before any work starts, because the neighborhood’s synchronized 1985-1995 construction window means original ductwork is failing on a predictable schedule. Call (737) 243-9544 and we’ll put a written price in your hand before a single panel comes off.
We dispatch to Wells Branch from our Austin office, and crews are familiar with the community’s specific housing stock - the tight cul-de-sacs off Wells Branch Parkway, the original 1980s and 1990s tract homes with flex duct in vented attics, and the newer infill builds near Heatherwilde Boulevard that still carry construction debris from drywall finishing. That local knowledge matters when a technician crawls into an attic and needs to distinguish between normal aging and a critical separation that’s been cooling 150°F attic air for three summers straight.
Why CleanRun Air Duct Cleaning Austin Is Wells Branch’s Preferred Duct Repair & Sealing Company
We’ve served Wells Branch since our founding in 2013, and the pattern is unmistakable: homes here fail differently than mixed-era Austin neighborhoods because they were built identically, all at once. Our Duct Repair & Sealing team knows what to expect when we pull back attic insulation on a 1989 build near Bratton Lane - brittle flex duct, separated mastic joints, and duct-board plenums that have begun delaminating at the air handler.
Our reputation here is documented, not claimed. Every Wells Branch job concludes with a photo record delivered to the customer: every duct run, before and after. The 365-Day Done Right Promise applies in writing, not as a verbal assurance. Tomas Reyes established this standard when CleanRun opened, and it has not changed.
Calls are answered by a live person, 24/7. Technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. We do not subcontract. The technician who quotes your job is the technician who performs it.
We also offer a Free Second Opinion on any written estimate from another company. Bring us a competitor’s quote; we put our number next to it in writing, with line-item scope, so you can compare documented work against documented work.
Our Duct Repair & Sealing Services in Wells Branch
Flex Duct Repair
Wells Branch’s original flex duct runs - the ribbed, insulated tubing installed in nearly every 1985-1995 home here - were rated for roughly 25 years of service. They’re now 30-40 years old. The plastic inner liner becomes brittle after decades of Central Texas heat cycling, and the fiberglass insulation compresses where the duct sags between trusses. We replace collapsed runs with new, properly supported flex duct using metal sleeves and UV-resistant zip ties, not tape. A typical flex duct repair in Wells Branch runs $280-$520 per run, with whole-home replacement starting around $1,800.
Duct Sealing & Mastic Sealant
Sealing is where most Wells Branch homes see immediate return. The original tape and mastic at trunk-line connections has dried and cracked, pulling return air from the attic instead of the conditioned space. We apply water-based mastic sealant (a thick, fiber-reinforced paste that remains flexible) to every joint, seam, and penetration, then pressure-test the system to verify leakage reduction. Mastic sealing of an average Wells Branch home’s accessible ductwork runs $340-$580. We use Abatement Technologies pressure-testing equipment to measure before-and-after leakage in CFM - documented in your job record.
Metal Duct Repair
Some Wells Branch homes, particularly later builds near McNeil Road and the commercial corridor, have galvanized steel trunk lines with flex duct branches. The metal itself rarely fails, but the longitudinal seams and takeoff connections corrode or separate. We re-seal with mastic and mechanical fasteners, replace rusted sections with snap-lock duct, and insulate to prevent condensation in humid attic conditions. Metal duct repair in Wells Branch typically runs $180-$420 depending on accessibility and extent.
Duct Insulation
Original flex duct insulation in Wells Branch attics has compressed to R-2 or lower in many homes, far below current code. In summer, when attic temperatures exceed 150°F, under-insulated supply ducts lose 15-25% of cooling capacity before air reaches the register. We re-insulate accessible runs with formaldehyde-free fiberglass wrap or replace with pre-insulated flex duct. Duct insulation work in Wells Branch averages $260-$480 for partial re-insulation, $890-$1,400 for full replacement with new insulated duct.

BeforeAfterTrusted Brands We Service in Wells Branch
CleanRun technicians carry professional-grade equipment from Rotobrush, Nikro, Honeywell, and Aprilaire - brands published here so Wells Branch customers can verify specifications independently before agreeing to any price. Our Rotobrush negative-pressure extraction systems and Honeywell media filtration components are standard on Wells Branch jobs. We do not use shop-vac adapters or consumer-grade tools. Parts for common Wells Branch systems are stocked locally, so flex duct repair and sealing jobs rarely wait on material orders. The equipment roster has not changed since 2013 because these manufacturers publish verified performance data; we do not make claims beyond what their documentation supports.
Common Duct Repair & Sealing Problems We See in Wells Branch Homes
- Collapsed flex duct at attic trunk connections. The original 1980s-90s flex duct in Wells Branch tract homes has sagged and separated at trunk-line connections in unconditioned attics, where summer attic temperatures exceed 150°F. Customers sometimes cool their attic space for years without knowing it, and a duct assessment visit becomes the moment the real structural failure gets diagnosed.
- Delaminating duct-board plenums. The pressed-fiberboard plenums installed at Wells Branch air handlers are now shedding their foil facing and leaking at seams. This drops static pressure, starves the blower motor, and causes the system to run longer cycles - visible on utility bills before it’s visible in comfort.
- Construction debris in newer Wells Branch homes. Homes handed over near Heatherwilde and newer infill areas still carry drywall dust, joint compound, and wood framing debris in supply and return ducts. The first “cleaning” these homes need is really builder cleanup, and sealing is often required because the debris has abraded mastic joints during the initial HVAC startup phase.
- Cedar Fever infiltration through unsealed return pathways. During December-February, when mountain cedar pollen counts peak, Wells Branch homes with leaky return ductwork pull unfiltered attic air directly into the system. Sealing returns and plenum connections is the structural fix; filtration upgrades address the symptom.

FAQs - Duct Repair & Sealing in Wells Branch
New construction ducts in Wells Branch often contain drywall dust, joint compound, and wood debris from the finishing phase, and the initial HVAC startup can abrade mastic joints before homeowners move in. We recommend assessment within the first 18 months on any new build, with documented photo evidence of what the builder left behind. Call (737) 243-9544 for a free estimate - estimates include the photo record.
The most reliable indicator is uneven cooling: back bedrooms or south-facing rooms that never match the thermostat, combined with utility bills that climb each summer despite no rate change. We verify with camera inspection - the technician photographs every duct run and shows you the separation before quoting repair. A homeowner on a 1980s flex-duct cul-de-sac off Wells Branch Parkway called us because the back bedrooms ran warm all summer; our tech’s camera inspection found the main trunk flex run had collapsed and separated from the plenum up in the 150°F attic, so the system had effectively been cooling the attic for years. We reconnected and mastic-sealed the trunk joint, re-insulated the sagging run, and after source removal on the supply and return ducts the back rooms finally matched the thermostat.
Yes, because December-February mountain cedar pollen is among the heaviest allergen loads in the country, and leaky return ductwork pulls unfiltered attic air directly into the system. Sealing returns and plenum connections before peak season reduces infiltration significantly; filtration upgrades alone cannot compensate for structural leaks. Call (737) 243-9544 to schedule assessment before December.
Every job starts with a written scope and price, then a camera inspection of every accessible duct run. We photograph the condition, perform the agreed repair - mastic sealing, flex duct replacement, metal repair, or insulation - pressure-test the system for leakage reduction, and deliver a documented photo record of every run before and after. The 365-Day Done Right Promise applies in writing. Typical residential jobs take 4-6 hours; whole-system replacement may require a return visit.
Yes. Wells Branch has notable density of 1980s-90s apartment complexes built during the same construction window as the single-family homes, with identical flex duct and duct-board materials now reaching end of service life. We perform commercial-scale duct assessment and repair for property managers, with the same documented photo record and written pricing structure. Multi-unit jobs are quoted per system, not per vent, with scope defined before work begins.
