Why Bellows Air Duct & Vent Co. of Texas Is Pflugerville’s Preferred Duct Repair & Sealing Company
We’ve earned our reputation in Pflugerville by showing up when we say we will and fixing the job right the first time.

Homeowners across Pflugerville’s master-planned communities have left us reviews praising our camera-verified results and our straightforward pricing, and we back every repair with our 90-Day Done Right Promise in writing.
Response time to Pflugerville is typically same-day or next-day, and we keep common flex duct fittings, mastic sealant, and insulation wrap stocked on every truck so we’re not making a second trip. We answer calls 24 hours a day with a live person, not a voicemail tree, because we know duct problems don’t wait for business hours. Wade Kellerman, our owner, built this company on the idea that a square deal means one honest price shown before work starts, and that standard hasn’t changed since 1984.
Our Duct Repair & Sealing Services in Pflugerville
Duct Sealing
We seal leaking duct joints and connections with professional-grade mastic sealant, not duct tape that dries out in Pflugerville’s attic heat. A typical duct sealing job in Pflugerville runs $280-$480 for a partial system and $550-$850 for full-system sealing, depending on accessibility and the condition of existing joints. We camera-inspect before and after so you see the difference.

Flex Duct Repair
Flex duct repair is what we do most often in Pflugerville. The builder-grade flexible duct in subdivisions like Stone Hill and Blackhawk was never meant to last 20 years in 140-degree attics, and we regularly find runs that have sagged, torn, or pulled completely off the register boot. Our crew replaces damaged sections with new insulated flex duct, secures them with metal collars and mastic, and adds support straps to prevent future sag. Most flex duct repairs in Pflugerville fall between $180-$340 per run.

Metal Duct Repair
While Pflugerville has very little pre-1990 housing with vintage galvanized ductwork, some custom homes and later renovations do use metal trunk lines that can corrode at seams or suffer impact damage. We patch metal ducts with proper sheet metal and sealant, or replace short sections when repair isn’t practical. Metal duct repair in Pflugerville typically runs $220-$450.

Duct Insulation
Uninsulated or degraded duct insulation in Pflugerville attics wastes enormous energy and creates condensation that feeds mold growth. We wrap repaired or exposed ductwork with fresh fiberglass insulation and vapor barrier, secured and sealed at every seam. Duct insulation work in Pflugerville generally costs $320-$580 depending on linear footage and attic access conditions.

Common Duct Repair & Sealing Problems We See in Pflugerville Homes
- Flex duct sags and detaches from register boots in sweltering attics. In Pflugerville’s 2000s-era subdivisions, the same two or three production builders ran identical flex-duct layouts across hundreds of homes. Secondary bedroom supply drops are almost always the first failure point, sagging away from the register boot in attic heat and pulling unfiltered attic air straight into your living space.
- Original builder mastic joints dry out and crack in extreme heat cycles. Pflugerville sits on the Blackland Prairie, where summer attic temperatures routinely exceed 140°F. The mastic sealant applied during original construction becomes brittle and separates at joints, causing conditioned air to leak into the attic before it ever reaches your rooms.
- Blown-in insulation conceals duct disconnections. Many Pflugerville homes have open-cell or blown-in insulation layered thick over attic air handlers. A duct can disconnect completely and vent conditioned air into the insulation for months with no visible warning, only showing up as a mysteriously high electric bill.
- Clay dust infiltration accelerates debris buildup. Pflugerville’s expansive black clay soils crack severely during drought cycles, allowing fine clay dust and allergens to infiltrate slab-on-grade homes. Once inside, this particulate gets pulled continuously into return-air systems, coating duct interiors and stressing connections.

FAQs - Duct Repair & Sealing in Pflugerville
Because two or three production builders used nearly identical duct layouts across master-planned subdivisions like Blackhawk and Falcon Pointe, and secondary bedroom supply drops are consistently the longest, most vulnerable flex-duct runs in those designs. The flex sags in attic heat, pulls away from the register boot, and leaks conditioned air into the attic instead of the bedroom. We recently repaired a duct system in Falcon Pointe where the bedroom supply drops had pulled away from the register boots, a pattern we see block after block in those 2008-2012 homes. Our crew reattached each flex duct with a new metal collar and mastic seal, then added insulation wrap to stop condensation in the Pflugerville summer attic. The homeowner avoided a full re-duct job. Call (866) 347-2063 for a free inspection if your bedrooms aren’t cooling evenly.
Mastic sealant alone can fix joint and seam leaks if the underlying ductwork is structurally sound, but it cannot repair detached flex duct or replace degraded insulation. In many 2009 Pflugerville homes, we find that original mastic has dried and cracked while the flex duct itself has also sagged or torn, meaning both repair methods are needed. We camera-inspect first to determine whether sealing, repair, or replacement is the right call for your specific system. Our $89 Seasonal Tune-Up includes a basic duct inspection if you’re unsure where to start. Call (866) 347-2063 to schedule.
Pflugerville’s expansive black clay soils crack severely during drought cycles, creating pathways for fine clay dust and allergens to infiltrate slab-on-grade homes through foundation gaps and exterior penetrations. This particulate loads up return-air filters faster and deposits inside ductwork, accelerating corrosion at metal joints and adding weight that stresses flex-duct connections. After we repair your ducts, we often recommend more frequent filter changes during dry summer months to protect the work. Call (866) 347-2063 and we’ll assess whether your return-air pathways need sealing against soil infiltration.
Repair is usually worth it if fewer than 30% of runs are damaged and the trunk line is intact. In Pflugerville’s 15-year-old homes, we typically find isolated flex-duct failures at bedroom supply drops while the main trunk and majority of runs remain serviceable for another decade. We replace the failed sections, reseal connections, and add support to prevent recurrence, a repair that usually costs $400-$900 versus $3,500-$6,500 for full replacement. If your system has multiple disconnected runs, degraded insulation throughout, or mold contamination, we’ll tell you honestly when replacement is the better investment. We also offer a Free Second Opinion on Any Written Estimate if another company has recommended full replacement. Call (866) 347-2063.
The biggest hidden failure is a completely disconnected return-air duct buried under blown-in insulation, venting attic air and particulates directly into your HVAC system while wasting 20-30% of your cooling capacity. Because Pflugerville homes have so much insulation layered over attic air handlers, this disconnection produces no visible dust or noise, only a creeping rise in electric bills and rooms that never reach set temperature. Our camera inspection finds these disconnections without tearing into insulation unnecessarily. If we find one, repair typically runs $280-$520 and restores efficiency immediately. Call (866) 347-2063 for a free estimate.
