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 Lago Vista
Duct repair and sealing in Lago Vista typically costs $280-$680 per air handler for flex-duct rebuilds and mastic sealing, with most jobs scheduled within 3-5 business days and completed in a single visit. Our crews coordinate dispatch from the Austin office and serve Lago Vista directly, carrying Rotobrush and Nikro equipment sized for the multi-system homes common on lake-terrace lots. Call (737) 252-1285 for a written estimate before any work starts.
We know Lago Vista’s housing stock - the 1960s cabins off Lohman Ford Road, the 2000s-2020s builds above Highland Lakes Drive, the vacation rentals along Lake Travis that sit empty for weeks then run hard through cedar season. Every system we touch gets a written price upfront, a camera-inspection record, and a pressure-drop verification before we leave. That’s Haven Standard Clause 1, and it’s how we’ve worked since 2013.
Why CleanRun Air Duct Cleaning Leander Is Lago Vista’s Preferred Duct Repair & Sealing Company
Our reputation in Lago Vista is built on documentation, not promises. We’ve served this market since expanding into Hill Country lake communities, and our Lago Vista customers return because the photo record shows what happened inside their attic - not because we told them to trust us.
Reviews from Lago Vista homeowners consistently cite the before-and-after photo deliverable as the deciding factor. They bought homes at peak Austin-exurb prices and expect trade work that can be verified. Our 365-Day Done Right Promise, backed in writing on every job, gives them a recourse if pressure readings drift or new leaks appear after cedar season.
Response time to Lago Vista runs 3-5 business days for standard duct sealing and flex-duct repair, with scheduling coordinated from our Austin office. We’re not guessing about your attic layout - our techs have worked the steep limestone lots above Lake Travis and know that a “simple seal” on Highland Lakes Drive often requires accessing a 22-foot flex run at a 140°F-stressed elbow.
Local knowledge matters because Lago Vista’s dual-threat climate varies block by block. Lakeside homes near the water draw enough humidity to grow mold inside ducts; uphill homes on cedar-covered limestone pull fine particulate that packs duct lining. A crew that treats both the same is guessing. We inspect first, then spec the repair.
Our Duct Repair & Sealing Services in Lago Vista
Duct Sealing
Sealing in Lago Vista starts with a pressure test, not a caulk gun. We pressurize the system, measure loss at each register and return, then target leaks with mastic sealant rated for the temperature swings these attics see. A typical duct sealing job in Lago Vista runs $280-$450 per system for accessible attic work. Homes with three air handlers - common in the 3,500+ square-foot builds above the lake - get priced per system, not lumped into a vague whole-house number. You know exactly what each system costs before we remove the first ceiling panel.
Flex Duct Repair
Flex-duct failures cluster on the highest attic runs in Lago Vista, where unshaded roof decking pushes temperatures past 140°F from June through September. The insulation delaminates. The interior liner tears at elbows. Then the system pulls cedar debris, limestone dust, and attic air directly into the conditioned space. Our Duct Repair & Sealing team rebuilds these runs with Guardsman-rated insulated flex, seals with mastic at every joint, and verifies with negative-pressure extraction and a final camera pass. Flex-duct repair in Lago Vista typically runs $340-$680 per run depending on length and access difficulty.
Metal Duct Repair
Older Lago Vista homes - the original lake cabins from the 1960s-1980s - often have galvanized metal ductwork that has corroded at seams or separated at collars. We cut out failed sections, fabricate replacements, and seal with mastic and fiberglass mesh for a repair that outlasts the original. Metal duct repair in Lago Vista runs $380-$720 per section, with written scope before cutting begins.
Duct Insulation
When flex-duct insulation has cooked beyond repair but the liner is intact, we wrap with foil-faced insulation rated for attic temperatures above 140°F. This is a common intermediate repair in Lago Vista’s uphill homes, where full replacement isn’t needed but bare flex will fail within a season. Insulation wrap jobs run $220-$380 per run.
Mastic Sealant Application
Mastic is the standard for durable sealing in high-temperature attics - tape fails, mastic doesn’t. We brush or trowel water-based mastic at every joint, collar, and penetration, then let it cure under negative pressure to confirm adhesion. This is included in our standard duct sealing scope, not sold as an add-on.

BeforeAfterTrusted Brands We Service in Lago Vista
We carry parts and materials from Honeywell, Aprilaire, and Rotobrush on every Lago Vista truck, and our flex-duct stock includes Guardsman-rated insulated product sized for the long runs common in lake-terrace homes. Nikro negative-pressure extractors handle the post-repair verification pull. You can look up every brand we name - we don’t use equipment we can’t document. For Lago Vista customers, this means same-day completion on most flex-duct and sealing jobs without waiting on parts from Austin.
Common Duct Repair & Sealing Problems We See in Lago Vista Homes
- Flex-duct insulation cooks and delaminates on the highest attic runs. In Lago Vista’s unshaded attics, the top 20% of any duct system sees the worst heat. The insulation separates from the flex core, then the core tears at the next stress point. The homeowner notices weak airflow upstairs, not the 140°F damage three feet below the ridge vent.
- Lakeside humidity grows mold; uphill homes pack with cedar and limestone dust. The humidity gradient around Lake Travis means a house on a low-elevation street off Lohman Ford Road may need mold remediation inside the duct before sealing, while a home 200 feet higher needs particulate extraction and filter upgrades. Same ZIP code, different repair spec.
- Second-home “on/off” cycles stress seams at the worst times. A Lake Travis rental that sits stagnant for three weeks, then runs 24/7 through December cedar season or June heat, pressurizes flex-duct seams that have hardened in the dry attic. The failure shows up as pressure loss and room-to-room imbalance, not a visible tear.
- Multi-system homes hide failures in the least-used zone. Lago Vista’s larger builds often have three air handlers with the master-suite system running least. That system’s attic flex sits hottest, longest, and fails first - but the homeowner feels it last because the other two systems compensate.

You get a written price for each air handler before work starts, and you can schedule one system or all three. No per-vent pricing, no $79 coupon that becomes $1,200 on the invoice. Haven Standard Clause 1: written price, every time.
Factors that push Lago Vista jobs toward the higher end: steep roof pitches that require harness work, rodent damage requiring multiple run replacements, and mold remediation inside lakeside ducts before sealing can begin. We tell you which applies before you agree to the work.

FAQs - Duct Repair & Sealing in Lago Vista
Each air handler is priced as a separate system with its own written scope, because each has its own attic routing, flex-run lengths, and failure points. A three-system home on a Lago Vista lake-terrace lot might have one system with 18 feet of exposed flex in a 140°F attic peak, another with short runs over conditioned space, and a third that sits unused for months. Lumping them into one “whole house” price means someone subsidizes someone else’s repair. Per-system pricing means you know what each costs, and you can schedule one now and defer others if you choose. Call (737) 252-1285 for exact per-system numbers - estimates are free.
Yes - cleaning removes what’s inside; sealing stops new pollen from entering through leaks. Lago Vista sits in the densest mountain cedar belt in the United States, and December through February fills attics with pollen that pulls directly into torn flex-duct liner or separated metal seams. Cleaning without sealing is a temporary fix. Sealing without cleaning leaves packed pollen that recirculates. We recommend both, with the seal verified by pressure test so the system doesn’t re-contaminate before cedar season ends. Call (737) 252-1285 to schedule before December.
You should receive three deliverables: a written scope and price agreed before work starts, a camera photo from inside every repaired or sealed duct run showing condition before and after, and a pressure-drop reading confirming the system holds spec. CleanRun’s Documented Photo Record is standard on every visit, not an upgrade. Haven Standard Clause 4 requires it. If a technician tells you the work is done but can’t show you the inside of the duct, the work isn’t documented.
They need inspection before heavy-use periods, not a calendar schedule. A Lago Vista vacation rental that sits empty for weeks, then runs hard through Memorial Day weekend or December cedar season, pressurizes stagnant ductwork at exactly the wrong time. We recommend a pre-arrival inspection and seal verification in late May and early November - before peak heat and peak pollen. The 365-Day Done Right Promise covers any seal failure that appears within a year of our work, even if the house was unoccupied for months in between.
We use Rotobrush agitation tools for debris loosening inside flex runs, Nikro negative-pressure extractors for post-reair verification, Honeywell and Aprilaire components for register and filtration upgrades, and Guardsman-rated insulated flex for rebuilds. Every brand is named on your written scope so you can verify specifications independently. We don’t use equipment we can’t document. Call (737) 252-1285 if you want to confirm a specific component before scheduling.
