You can reach us at (737) 259-5752 for a written estimate with no obligation.
We’ve worked in Georgetown homes long enough to know the difference between a standard duct sealing job and what this market actually demands. The Balcones Escarpment doesn’t just shape the terrain here. It shapes what’s inside your ductwork.
Why CleanRun Air Duct Cleaning Round Rock Is Georgetown’s Preferred Duct Repair & Sealing Company
Our Duct Repair & Sealing team has completed thousands of jobs in Williamson County since 2013, and Georgetown represents a distinct category of work within that count. The combination of Sun City Texas slab construction, explosive new growth in Wolf Ranch and Teravista, and the most concentrated Ashe juniper pollen event in North America means a technician who treats this like a generic Austin suburb will miss what’s actually wrong.
We don’t guess. Every Georgetown job starts with a camera inspection, a written price under Haven Standard Clause 1, and a documented photo record of every duct run before we touch anything. Our crews are background-checked, uniformed, and identified by name before arrival, operating under Haven Standard Clause 3: Verified Crews.
Homeowners in Georgetown have left us a strong local reputation built on one specific practice: we show the photo before we recommend the repair. The 365-Day Done Right Promise backs every job in writing, not as a policy subject to manager approval but as a contractual deliverable.
Calls are answered by a live person, 24/7. Scheduling to Georgetown is coordinated from our Austin office with local crew dispatch.
Our Duct Repair & Sealing Services in Georgetown
Duct Sealing
Unsealed ductwork in Georgetown loses 20-30% of conditioned air to attics, crawl spaces, and slab voids before it reaches your registers. In Sun City Texas homes, we regularly find boot connections that were never sealed during original construction, creating direct pathways for caliche dust and cedar pollen to bypass your filter entirely. Our duct sealing process uses mastic sealant and mechanical fasteners, not tape that degrades in Texas heat, and every sealed joint is pressure-tested before we close the access panel. A typical duct sealing job in Georgetown runs $280-$450 for a single-zone system.
Flex Duct Repair
Georgetown’s post-2000 master-planned homes feature long flex-duct runs across open floor plans, and after 15-25 years of continuous heating-season operation, these runs kink, sag, or crush at support points. In Teravista and Saddle Creek, we’ve replaced entire flex runs that had collapsed to half their original diameter, cutting airflow to back bedrooms by 40% or more. Our flex duct repair uses insulated, reinforced duct rated for the temperature swings of Hill Country attics, supported at proper intervals to prevent future sag. Replacement of a single crushed flex run in Georgetown typically costs $180-$340; whole-system replacement in larger homes runs $1,200-$2,400.
Metal Duct Repair
Older metal ductwork in Georgetown’s pre-2000 construction and some commercial applications develops seam separation, corrosion at joints, and damage from improper previous repairs. We patch or replace metal sections using proper sheet-metal fabrication, seal with mastic, and insulate to prevent condensation in humid summer conditions. Metal duct repair in Georgetown generally falls between $320-$680 depending on accessibility and extent of damage.
Duct Insulation & Mastic Sealant
Under-insulated ducts in Georgetown attics lose efficiency year-round, but the real problem we see is poorly applied or degraded sealant that lets attic air mix with conditioned air. Our mastic sealant application covers every joint, seam, and penetration with a brush-applied, fiber-reinforced compound that remains flexible through decades of thermal cycling. We pair this with proper insulation replacement where existing wrap has compressed or torn. Mastic sealing with spot insulation repair in Georgetown typically runs $350-$580.

BeforeAfterTrusted Brands We Service in Georgetown
Our equipment roster includes professional-grade tools from Nikro, Honeywell, and Aprilaire, brands you can verify independently before agreeing to any work. We stock common duct repair components locally for Georgetown jobs, including flex duct, mastic, mechanical fasteners, and register boots, which means most repairs are completed in a single visit without waiting on parts. For air quality upgrades following repair work, we install Aprilaire media filters and Honeywell whole-home purifiers with documented MERV ratings, not marketing claims.
Common Duct Repair & Sealing Problems We See in Georgetown Homes
- Unsealed boot connections in Sun City slab homes. The limestone soil and persistent wind off the Balcones Escarpment create negative pressure at slab level that pulls caliche dust and cedar pollen directly into return plenums through gaps around register boots. We find this in roughly half the Sun City homes we inspect that have never had professional duct service.
- Kinked or sagging flex duct in 15-25-year-old systems. Georgetown’s continuous heating use through December-February causes repeated expansion and contraction in attic flex runs. Over years, support straps fail and ducts sag onto insulation or framing, creating sharp bends that choke airflow to distant rooms.
- Post-construction caliche dust masking leaks in newer homes. In Wolf Ranch and Teravista, we’ve opened ducts in homes less than five years old and found caliche limestone dust coating interior surfaces so thickly that it obscures seams and joints. Some contractors seal over this debris; we remove it first with Rotobrush agitation and negative-pressure extraction, then seal clean metal.
- Insulation degradation from attic heat and rodent activity. Hill Country attics regularly exceed 140°F in summer, accelerating compression and tearing of duct insulation. Combined with roof rat pressure in established Georgetown neighborhoods, this creates exposed metal that sweats moisture and breeds mold in shoulder seasons.

FAQs - Duct Repair & Sealing in Georgetown
Yes, but only if the sealing addresses the specific infiltration paths that cedar pollen uses in Georgetown homes. Sealing return plenum boots, repairing damaged flex runs, and ensuring your filter cabinet is properly gasketed will reduce the pollen load entering your system. It won’t eliminate cedar pollen from your indoor air entirely, because some enters through doors, windows, and on clothing. In Sun City Texas homes with unsealed slab-level boots, we’ve measured significant reduction in register dust within one heating season after proper mastic sealing. Call (737) 259-5752 for an inspection that identifies your specific infiltration points.
Expect to find original flex duct that has sagged or kinked at support points, boot connections that were never sealed with mastic, and a return plenum that may contain visible layers of cedar pollen, caliche dust, and insulation fibers. We inspect with a camera first, provide a written price before any work, and deliver before-and-after photos of every duct run. Most Sun City whole-system repairs run $1,400-$2,600 depending on home size and extent of duct degradation. The work typically takes one full day, and we schedule with low-disruption timing for residents who are home during the day.
Yes. We schedule Georgetown jobs with specific arrival windows, not all-day waits, and our technicians call 30 minutes before arrival. For Sun City Texas residents and others who are home throughout the day, we offer morning-start appointments that typically conclude by early afternoon, minimizing the time your system is offline. We also protect floors and furniture, work room-by-room rather than opening every register simultaneously, and clean work areas before departure. The documented photo record is delivered electronically, so no second visit is needed for review.
Caliche is calcium carbonate-cemented soil, essentially natural concrete, that forms in the limestone geology of the Balcones Escarpment. When disturbed by construction, wind, or slab settling, it produces extremely fine, abrasive particles that resist standard vacuuming and embed in duct seams. Unlike organic dust, caliche doesn’t break down or degrade; it accumulates in layers that can visibly coat duct interiors within months of construction completion. In Georgetown, we remove caliche with mechanical agitation (Rotobrush) under negative pressure, then seal clean surfaces, because sealing over caliche guarantees early failure. This specific soil condition doesn’t exist at this concentration in clay-soil suburbs like Hutto or Round Rock.
We use a three-step verification: visual camera inspection of every accessible run, pressure differential testing across the air handler, and smoke-pencil detection at registers and boots. In Georgetown homes, we pay particular attention to slab-level boot connections and attic flex junctions, which are the dominant leak paths we find. The camera shows debris patterns that reveal hidden leaks; pressure testing quantifies total system leakage; smoke testing locates exact points. All findings are photographed, included in your written estimate, and reviewed with you before any sealing begins. Call (737) 259-5752 to schedule this inspection.
