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 Lakeway
Duct repair and sealing in Lakeway typically runs $340-$890 for most residential jobs, with flex duct replacement in original 1970s homes landing at the higher end due to attic access challenges. We also offer Lakeway Dryer Vent Cleaning to address another common fire-safety issue in these same attic spaces. Our crews dispatch from the Austin office and carry the equipment to handle both crushed flex duct runs in older resort-era homes and complex zoned systems in newer Lakeway developments. Call (737) 259-5752 for a written estimate before any work starts - Haven Standard Clause 1.
We’ve been working in Lakeway since 2013, and the pattern is consistent: homes built during the original resort development years have flex duct in attics that was never designed to survive 50+ summers of 150°F heat. The result is collapsed runs, disconnected joints, and systems that pull in cedar pollen and limestone dust through gaps the homeowner can’t see. Our Duct Repair & Sealing team documents every finding with before-and-after photos of the duct interior, delivered as part of the standard job record.
Why CleanRun Air Duct Cleaning Round Rock Is Lakeway’s Preferred Duct Repair & Sealing Company
Lakeway homeowners tend to research thoroughly before calling - we know because they ask specific questions about mastic sealant curing times, R-8 flex duct R-values, and whether we’ll photograph the actual duct runs, not just the registers. We’ve built our reputation here on answering those questions with documented evidence, not assurances.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. Tomas Reyes established CleanRun in 2013 with the requirement that every job, including every Duct Repair & Sealing in Lakeway, closes with a written price agreed beforehand and a photo record of every duct run after. No exceptions. The 365-Day Done Right Promise applies here exactly as it does everywhere we serve: if the work is not right, we make it right, backed in writing.
We’ve completed duct repair and sealing work across Lakeway’s full housing spectrum, from original 1970s ranch homes near Lakeway Boulevard to multi-story custom builds in Rough Hollow. The problems differ. The documentation standard does not.
Our Duct Repair & Sealing Services in Lakeway
Flex Duct Repair
This is our most common scope in Lakeway. The original 1970s resort-era homes here hide flex duct in sweltering attics where the inner liner can collapse almost completely under the combined weight of heat, cedar pollen, and limestone dust - a failure mode that’s rare in the flat, newer suburbs of Austin and most other Texas metros. Our flex duct repair work here heavily focuses on restoring crushed attic runs, not just mastic-sealing disconnected joints. We remove the damaged run, install new R-8 flex duct rated for extreme attic temperatures, and seal every connection with mastic sealant. The photo record shows the collapsed run and the restored airflow path.
Duct Sealing
Sealing in Lakeway addresses gaps that pull unconditioned attic air into the living space. Original metal duct joints in resort-era homes separate as the duct expands and contracts in extreme attic temperatures, pulling in pollen-laden air through every gap. In newer Lakeway Highlands builds, complex zoned systems develop leaks at branch connections that reduce efficiency without obvious symptoms. We seal with mastic, not tape - mastic remains flexible across temperature swings and won’t degrade under Lakeway’s attic conditions. Every sealed joint is photographed.
Metal Duct Repair
Some Lakeway homes, particularly those built during the early resort development, used galvanized metal trunk lines with flex branch takeoffs. The metal itself can separate at seams or corrode where condensation collects. We repair or replace metal sections, reconnect with proper mechanical fasteners, and seal with mastic. Metal duct repair in Lakeway attics requires working in confined spaces at high temperature - our crews carry portable ventilation and work in shifts when necessary.
Duct Insulation
When we replace flex duct in Lakeway’s 150°F attics, we specify R-8 insulation minimum - the highest standard readily available for residential flex duct. Original 1970s duct may carry R-4 or R-6, which is insufficient for Hill Country attic exposure. Better insulation reduces conductive heat gain, which means your conditioned air arrives at the register closer to the temperature your thermostat requested. The difference is measurable: we’ve documented supply air temperature improvements of 8-12°F after R-8 replacement in Lakeway attics.

Our equipment roster includes Rotobrush for mechanical agitation in duct runs, Nikro negative-pressure extraction systems, and Honeywell media filters and zoning controls for post-repair air quality upgrades. We don’t stock every part for every brand, but we carry common flex duct diameters, mastic, and connection hardware on every Lakeway truck. For specialized components in zoned systems - particularly in Rough Hollow custom homes with complex controls - we source through local suppliers with next-day availability. The brands we use are ones you can look up independently: Guardsman for certain sealant applications, Rotobrush and Nikro for the core cleaning and extraction work.
Common Duct Repair & Sealing Problems We See in Lakeway Homes
- Collapsed flex duct in original 1970s-80s attics. The inner liner degrades from 150°F summer heat and the weight of accumulated cedar pollen and limestone dust, choking airflow to a trickle. Homeowners notice weak supply at distant registers first. The camera shows the sag before we remove anything.
- Disconnected or crushed runs behind drywall in multi-story Rough Hollow custom homes. These go unnoticed until a blower motor overheats from the added static pressure. We find them during camera inspection, not guesswork.
- Original metal duct joints separating in resort-era homes. Expansion and contraction in extreme attic temperatures open gaps that pull unconditioned, pollen-laden attic air into the system. The homeowner smells attic dust or sees elevated particle counts; the smoke pencil shows the leak path.
- Cedar pollen accumulation accelerating liner degradation. Microscopic cedar pollen particles infiltrate return-air grilles and coat ductwork interiors. In Lakeway’s original flex duct, this accumulation adds weight and retains moisture, speeding the breakdown of the inner liner. Post-cedar-season inspections - January through March - regularly reveal damage that wasn’t visible the previous fall.
Pricing for Duct Repair & Sealing in Lakeway, TX
A typical duct sealing job in Lakeway runs $340-$580 for a single-system home with accessible attic space. Flex duct repair or replacement in original 1970s homes, where crushed runs are common, typically falls between $520-$890 depending on linear footage and attic access difficulty. Metal duct repair starts around $480 for localized seam sealing and can reach $1,200+ for extensive trunk line reconstruction. Duct insulation upgrade during replacement adds $180-$340.
What moves the price: attic accessibility (tight truss spacing common in 1970s builds adds labor), number of duct runs affected, and whether the system requires rebalancing after repair. Every price is written before work starts - Haven Standard Clause 1 - and includes the documented photo record. No per-vent pricing, no add-ons after the truck arrives.

FAQs - Duct Repair & Sealing in Lakeway
Lakeway’s original 1970s resort-era homes were built with flex duct in unconditioned attics that routinely exceed 150°F, and the inner liner was not engineered for that sustained heat load. The added weight of cedar pollen accumulation - unique to the Hill Country juniper belt - and caliche dust infiltration causes sagging and collapse that’s rare in flat-terrain suburban builds with newer materials. Call (737) 259-5752 for a camera inspection that shows the actual condition of your attic runs.
We run a camera through every accessible duct run during our pre-work inspection - this is standard on every Lakeway job, not an add-on. The camera shows a 3-inch debris build-up at the first elbow, a fully collapsed liner, or a disconnected joint hanging open. You see the image before we write the scope. Call (737) 259-5752 to schedule.
Yes. Cedar pollen season peaks December through February in Lakeway, and microscopic particles infiltrate through every gap in the duct system. Sealing gaps before or immediately after cedar season prevents the accumulation that degrades flex duct liners and degrades indoor air quality for months afterward. The sealing work is the same; the timing matters more here than in areas with milder pollen loads. Call (737) 259-5752 for a pre-season inspection.
Typically: camera inspection of all attic runs, removal of collapsed or degraded flex duct, installation of new R-8 flex duct with proper support straps, mastic sealing of every joint and connection, and rebalancing of supply and return airflow. Our tech was called to an original 1972 ranch-style home near Lakeway Boulevard after the homeowner noticed weak airflow in the master bedroom and a whistling return. Using a camera inspection, we found a 25-foot flex duct run in the attic that had fully collapsed on itself - the inner liner was sagging under years of cedar pollen and caliche dust, and the connection at the air handler was hanging loose. We removed the crushed run, installed new R-8 flex duct, sealed every joint with mastic, and rebalanced the supply and return ducts; airflow at the register more than doubled. The photo record documented every stage. Call (737) 259-5752 for a written scope on your home.
Original 1970s-80s flex duct in Lakeway should be camera-inspected every 3-5 years given the attic heat load and pollen exposure. Newer homes with properly installed R-8 duct and quality sealing can go 7-10 years between inspections unless symptoms appear - weak airflow, uneven temperatures, or elevated energy bills. The 365-Day Done Right Promise covers any sealing failure within the first year. Call (737) 259-5752 to set a baseline inspection.
