Why Bellows Air Duct & Vent Co. of Texas Is Bee Cave’s Preferred Duct Repair & Sealing Company
We’ve been serving Bee Cave long enough to remember when Falconhead was still breaking ground and Spanish Oaks was mostly cedar scrub. That history matters because the ductwork problems we see in Bee Cave’s master-planned communities aren’t random - they follow patterns tied to how these homes were built, when they were built, and what the Hill Country climate does to them.
Our technicians are background-checked, uniformed, and carry the same professional-grade equipment Rotobrush and Nikro manufacture for serious HVAC contractors. Every job gets camera-inspected before and after, so you see what we see. Calls to (866) 347-2063 are answered by a live person, 24 hours a day - not a voicemail tree, not an app.
The 90-Day Done Right Promise applies to every Bee Cave job we do. If it’s not right, we return at no charge. No paperwork, no arguing. That’s been our standard since 1984, and Wade Kellerman doesn’t intend to change it.
Our Duct Repair & Sealing Services in Bee Cave
Flex Duct Repair
In Bee Cave’s newer master-planned homes, builders often used low-cost flex ducts that degrade rapidly in attics exceeding 130°F, leading to seal failures and dust infiltration within 5-7 years. We repaired a flex-duct tear in a Falconhead home’s master bedroom zone, where the builder’s original duct had split near the air handler. We reconnected it with mastic sealant and reinforced with a metal collar, restoring airflow and stopping dust intrusion. Most flex duct repairs in Bee Cave run $280-$420, depending on accessibility and the extent of liner degradation.
Duct Sealing
Multi-zone systems with long flex-duct runs - common in 3,000-5,500 sq ft Bee Cave homes - often develop leaks at joints and connections that you can’t see but definitely pay for. Our sealing process targets these pressure points with mastic and mechanical reinforcement, not tape that dries and fails. A typical whole-system sealing for a Bee Cave home runs $450-$780. Homes backing up to cedar-covered ridgelines in Spillman Ranch see particular benefit, since sealed returns don’t pull unfiltered pollen through gaps.
Metal Duct Repair
Older metal ductwork in Bee Cave properties - less common but present in some early-2000s builds - suffers from seam separation and corrosion where condensation meets Hill Country limestone dust. We cut out damaged sections, fabricate replacements, and seal with mastic for a permanent fix. Metal repairs typically start around $320 and range to $580 for moderate damage.
Duct Insulation & Mastic Sealant
Bee Cave attics hit 130°F-plus for months each summer. That heat cooks the insulation backing on flex ducts and degrades mastic over time. We reinsulate with foil-faced wrap rated for extreme attic temperatures and apply fresh mastic sealant at every joint. Insulation upgrades run $180-$340 per duct run, with mastic touch-ups at $120-$220 for targeted sealing.

Common Duct Repair & Sealing Problems We See in Bee Cave Homes
- Builder-grade flex ducts in attics over 130°F lose insulation value and develop cracks within 5-7 years, causing conditioned air loss and dust entry. We see this constantly in 2015-2020 builds where the original ductwork is now right at that failure window.
- Multi-zone systems with long flex-duct runs often have sagging sections that trap moisture, promoting mold growth and reducing efficiency. Bee Cave’s humidity spikes after Hill Country thunderstorms make this worse than in drier West Texas markets.
- Cedar-season pollen loads overwhelm return grilles, leading to increased static pressure and leakage at duct joints. The Ashe juniper belt doesn’t just cause sneezing - it forces your system to work harder against partially blocked returns.
- Visible amber pollen coating on return-air grilles within days of a cedar-release cold front - a hyper-local pattern in subdivisions like Falconhead and Spillman Ranch that back directly up to cedar-covered ridgelines. This prompts many allergy-sensitive households in 78738 to schedule duct evaluation as a near-annual post-cedar-season ritual.

FAQs - Duct Repair & Sealing in Bee Cave
Every 5-7 years for most Bee Cave homes, or sooner if you notice dust increase, uneven cooling, or post-cedar-season allergy spikes. The combination of extreme attic heat and cedar pollen stress accelerates seal degradation compared to milder climates. Call (866) 347-2063 to schedule an evaluation - our $89 Seasonal Tune-Up includes a camera inspection that spots problems before they spread.
Yes, proper duct sealing significantly reduces pollen infiltration by closing the gaps in your return ductwork where unfiltered outdoor air gets pulled in. In Bee Cave, where December-February cedar releases saturate 78738 with microscopic pollen, sealed returns are one of the most effective non-pharmaceutical defenses for allergy-sensitive households. We see the biggest improvement in homes backing up to ridgelines in Falconhead and Spillman Ranch. Call (866) 347-2063 for a free estimate.
Yes, 2018 is right in the window where Bee Cave builders commonly used lower-grade flex duct that degrades fastest in extreme attic heat. You’re likely at year 6 or 7 now, which is when we see the first wave of liner cracks and seal failures in this vintage. A camera inspection will show exactly where you stand - no guesswork, no scare tactics. Call (866) 347-2063 to book.
Yes, we apply professional-grade mastic sealant to metal duct seams and connections, which outlasts tape and handles Bee Cave’s thermal expansion cycles better than any adhesive product. Metal ductwork with proper mastic sealing can perform reliably for 15-20 years even in our harsh attic conditions. Most metal sealing jobs run $320-$580. Call (866) 347-2063 for an exact quote - estimates are free.
A full duct sealing for a 4,000 sq ft Bee Cave home with multi-zone HVAC typically runs $580-$920, depending on zone count, attic accessibility, and whether any flex duct sections need replacement. Homes in Spanish Oaks or Falconhead with four or five zones and long attic runs tend toward the higher end. We apply our $50 Off Any Repair Over $250 to most jobs this size, and seniors and veterans save an additional 5% permanently. Call (866) 347-2063 for your exact number - estimates are free.
