Georgetown’s housing tells three different stories. You’ve got the older in-town homes with original flex duct or fiberglass duct board from the Carter and Reagan eras. You’ve got Sun City Texas, where thousands of homes went up between the late 1990s and 2010s with builder-grade materials that are now hitting their failure window. And you’ve got the explosive new construction in Wolf Ranch, Morningstar, and Teravista, where post-build debris in brand-new ducts is already a known issue. Each needs a different approach. We bring a camera, we look before we quote, and we seal what actually needs sealing - nothing more.
Why Bellows Air Duct & Vent Co. Is Georgetown’s Preferred Duct Repair & Sealing Company
We’ve been serving Georgetown since 2012, back when the population was under 10,000 and Williams Drive was still two lanes in spots. Ray Castillo built this company on the idea that a homeowner should know the price before a tool comes out of the truck, and that hasn’t changed. Our 90-Day Done Right Promise is stamped on every job - if it’s not right, we come back at no charge, no paperwork, no arguing. That’s not marketing language; it’s how we’ve operated for four decades.
Our technicians are background-checked, uniformed, and equipped with professional-grade gear from Nikro and Honeywell. Most repairs are completed in a single visit. Calls to (844) 685-6342 are answered by a live person, 24 hours a day - not a voicemail tree, not an app. Georgetown homeowners who’ve been burned by low-bid bait-and-switch operators tell us that’s why they keep our number on the fridge.
We know the local conditions that break ductwork here. The Balcones Escarpment’s dense Ashe Juniper loads pollen into return intakes every December through February. Summers at 100°F-plus run air handlers almost nonstop from June through September. That combination - heavy biological loading plus thermal stress - ages duct systems faster in Georgetown than in cooler, less pollen-dense markets to the north. We’ve seen it in attics across 78626, 78627, 78628, and 78633.
Our Duct Repair & Sealing Services in Georgetown
Flex Duct Repair
Flex duct is the soft, insulated tubing that connects your main trunk lines to individual room vents. In Georgetown, we see two distinct flex duct failure patterns. Sun City Texas homes from the 1990s through 2010s were built with original builder flex that’s now sagging, kinked, or pinholed from decades of attic heat cycling. The material simply wasn’t built to last 20-plus years in a Texas attic. In older in-town homes, we’ve found flex that’s been chewed by rodents or crushed by storage boxes in tight crawl spaces.
Our flex duct repair includes removing damaged sections, installing new insulated flex with proper support straps to prevent future sagging, and sealing all connections with mastic. A typical flex duct repair in Georgetown runs $180-$340 per branch line. We camera-inspect before and after so you see the difference.
Mastic Sealant Application
Mastic is a thick, water-based sealant we brush or trowel onto duct joints, seams, and connections. Unlike foil tape, which dries out and peels in attic heat, mastic remains flexible and forms a permanent airtight bond. This matters enormously in Georgetown, where attic temperatures routinely exceed 140°F in summer and thermal expansion constantly stresses duct connections.
We apply mastic to every accessible joint in your system - supply and return - after cleaning debris from the seam surfaces. A full mastic sealant treatment for an average Georgetown home runs $350-$550. For Sun City Texas homes with original builder ductwork, this is often the single most cost-effective improvement you can make, cutting air loss by 20-30 percent in systems where joints have never been properly sealed.
Air Leak Repair
Air leaks in ductwork waste money and strain your HVAC equipment. In Georgetown, we find them in predictable places: disconnected flex-to-metal connections in Sun City attics, corroded supply plenums in 1970s-80s homes near the historic square, and poorly sealed register boots in new construction where speed trumped quality. The cedar pollen that infiltrates through these leaks is what separates Georgetown from markets without comparable allergen loads - it’s not just wasted air, it’s contaminated air.
We locate leaks with pressure testing and camera inspection, then repair with appropriate methods: mastic sealing, metal patching, flex replacement, or plenum reconstruction. Air leak repair in Georgetown typically ranges from $200-$480 depending on accessibility and extent. Every repair is camera-verified before we close up.
Metal Duct Repair
Older Georgetown homes, particularly those 1970s-80s builds in the historic district and near Southwestern University, often have galvanized steel trunk lines and supply ducts. These can corrode at seams, separate at slip joints, or develop holes from contact with electrical wiring or fasteners. Metal duct repair requires sheet metal skills that many discount operators simply don’t have - we fabricate custom patches, re-seal joints with mastic and mechanical fasteners, and reinforce weak sections. Metal duct repair in Georgetown runs $280-$520.
Duct Insulation Replacement
When duct insulation gets wet from condensation, damaged by rodents, or simply degrades after decades in a hot attic, your system loses thermal efficiency and can start sweating, causing ceiling stains or mold concerns. We remove compromised insulation and install new R-6 or R-8 fiberglass wrap with vapor barrier, sealed at every seam. Duct insulation work in Georgetown typically costs $300-$600 for accessible trunk lines.

Common Duct Repair & Sealing Problems We See in Georgetown Homes
- Original builder flex duct in Sun City Texas homes (1990s-2010s) sags and develops pinhole leaks after decades of attic heat, wasting conditioned air and cycling 100°F-plus summer air through compromised insulation. Many homeowners moved from out of state and have never experienced Central Texas thermal stress on flexible materials.
- Leaky return plenums in older in-town homes near the historic square (1970s-80s) pull in attic dust and cedar pollen, overwhelming filters and reducing indoor air quality. The return side operates under negative pressure, so every gap becomes an intake for whatever is in your attic or wall cavities.
- New-construction master-planned communities like Wolf Ranch and Teravista often have drywall dust and insulation debris trapped in ducts post-build, requiring thorough sealing after cleaning. We’ve opened registers in two-year-old homes and found construction debris packed against the damper.
- Separated metal duct joints throughout Georgetown’s housing stock whistle when the AC cycles on, especially in summer when system pressure peaks. That whistle is conditioned air escaping into your attic - air you paid to cool.

FAQs - Duct Repair & Sealing in Georgetown
Georgetown’s cedar pollen season, peaking December through February, forces your HVAC system to recirculate allergen-laden air through any gap or leak in your ductwork. The Ashe Juniper on the Balcones Escarpment produces some of Texas’s heaviest pollen loads, and that pollen infiltrates return air intakes through unsealed plenums, register gaps, and filter bypasses. Proper mastic sealing and leak repair reduces indoor pollen concentration significantly. If your allergies spike every January despite a clean filter, you likely have return-side leakage. Call (844) 685-6342 and we’ll pressure-test your system to find the gaps.
Most 2002 Sun City Texas flex duct is at or past its reliable service life and should be evaluated for replacement rather than repeated repair. The original builder-grade flex was not designed for 20-plus years of Georgetown attic heat, and by now you’re likely seeing sagging, insulation degradation, and pinhole leaks throughout the system. In Sun City Texas near the Del Webb clubhouse, we repaired a 15-year-old flex duct system where the original uninsulated metal supply runs had separated at the joints due to age and humidity. After sealing with mastic and replacing a collapsed flex branch, we restored balanced airflow and eliminated a whistling noise. The homeowner had never had the ducts inspected since moving from California. For a 2002 system, we typically recommend partial or full replacement with supported, properly insulated flex - repair is a short-term patch. A full replacement in Georgetown runs $1,800-$3,200 for an average Sun City home. We’ll camera-inspect and give you an honest assessment with no pressure.
Yes - post-construction debris and builder-speed installation practices often leave new Wolf Ranch and Teravista homes with significant leakage and contamination. We’ve found drywall dust, insulation scraps, and even fastener debris packed into ductwork in homes less than two years old. The ducts may be new, but they’re rarely clean or well-sealed. We recommend a camera inspection and targeted sealing within your first year of occupancy. The $89 seasonal tune-up is a good entry point - we’ll look inside and tell you what actually needs attention.
Whistling at duct seams indicates high-velocity air escaping through gaps or separations, most commonly where metal trunk lines connect to flex branches or where slip joints have worked loose under thermal cycling. In Georgetown, this worsens in summer when your system runs longer and at higher static pressure. The whistle is literally your money escaping into the attic. We locate the source with pressure testing and camera inspection, then seal with mastic or mechanical repair. Most whistling repairs in Georgetown are completed in a single visit for $200-$400. Call (844) 685-6342 for a free estimate.
Older homes near Georgetown’s historic square with 1970s-80s duct systems are among the most leak-prone we service. Original fiberglass duct board or early flex duct has often degraded, and return plenums frequently pull in attic air loaded with dust and cedar pollen. Sealing these systems - particularly the return side - improves air quality and reduces HVAC runtime noticeably. We’ve seen 25-35 percent airflow improvement after proper mastic sealing in these older homes. The work typically runs $350-$550 and pays back in comfort within the first summer. Call (844) 685-6342 to schedule a camera inspection - estimates are free.
