Duct Sealing in Shady Hollow - Tested First, Written Price Second

Fast, Reliable Duct Sealing Across Shady Hollow

Duct sealing in Shady Hollow typically runs $450 – $1,200 for a whole-home system, with most jobs completed in a single visit and priced in writing before we start. If your HVAC bills keep climbing or certain rooms never reach the thermostat setting, the problem is often air leaking into your attic or crawl space through gaps in the ductwork, not the unit itself.

Call (361) 326-5060

We know Shady Hollow well. Our crews dispatch from the Austin office and regularly work the winding streets off Brodie Lane, the wooded lots along Slaughter Creek, and the custom homes near the Shady Hollow Community Park. The mature live-oak canopy that makes this neighborhood beautiful also creates conditions we see nowhere else: squirrels and raccoons nesting in attic duct runs, leaf litter pulled into return plenums, and pier-and-beam homes with flex duct crushed or disconnected under the floor where wildlife entered through foundation vents. That local knowledge changes how we approach the job and what we find when we get into the system. Call (361) 326-5060 for a free estimate.

Air Duct Sealing in Shady Hollow

Air Duct Sealing in Shady Hollow means closing the gaps, seams, and connection points where conditioned air escapes your duct system before it reaches the rooms you actually live in. In a neighborhood where most homes were built between the 1970s and 1990s, the original ductwork is often flex duct or early rigid-metal trunk lines that have separated at joints, dried out at collars, or been disturbed by decades of attic traffic from wildlife. We seal with mastic compound and metal-backed tape rated for HVAC temperatures, not the hardware-store duct tape that fails in a season or two.

Most Shady Hollow homeowners call us after noticing hot second floors, cold spots in back bedrooms, or utility bills that jumped without explanation. The Central Texas heat pushes systems to run nearly year-round, so even a 15 – 20% air loss through leaks forces the compressor to work harder and longer. Our Duct Sealing team starts with a pressure test to measure exactly how much air you’re losing, then seals every accessible joint and registers the improvement before we leave.

Attic Duct Sealing

Attic runs in Shady Hollow suffer from temperature extremes and wildlife intrusion. We pull back insulation, seal each connection with mastic, then restore the thermal barrier so your conditioned air stays in the ducts, not heating your attic in July.

Crawl Space and Pier-and-Beam Repair

On pier-and-beam homes common in the older sections near Slaughter Creek, flex duct under the floor often gets crushed by settling or torn by animals entering through foundation vents. We repair or replace damaged sections and seal the system to prevent recurrences.

Duct Sealing Services in Shady Hollow

Duct Sealing Services in Shady Hollow cover everything from spot repairs on disconnected flex runs to full-system mastic sealing for homes with 30-year-old metal trunk lines. Because this neighborhood’s housing stock is almost entirely custom and semi-custom single-family homes on large wooded lots, no two systems are identical. Some homes have been retrofitted with zoning dampers; others still run the original single-zone layout. Our technicians assess what’s actually in your attic or crawl space, explain what we found, and give you a written price before we open a single sealant bucket.

The cedar pollen season here runs December through February, and spring oak pollen follows immediately after. That sticky pollen coats evaporator coils and lines ductwork in ways dry-climate dust doesn’t. When your ducts leak, that pollen gets pulled into wall cavities and ceiling spaces, then circulates back into the living area through any gap it can find. Sealing the duct system stops that cycle. We also offer Air Duct Cleaning in Shady Hollow for homes where the buildup has already occurred, and Dryer Vent Cleaning in Shady Hollow to complete the ventilation picture.

Pressure Testing and Leak Detection

We pressurize the duct system and measure leakage against industry standards. In Shady Hollow’s older homes, we regularly find systems losing 25 – 40% of conditioned air. The test gives us a baseline and proves the improvement after sealing.

Register and Boot Sealing

Wall and ceiling registers often separate from drywall or duct boots over decades of thermal cycling. We seal these connection points with mastic and proper backing so air stops leaking into wall cavities.

Trusted Brands We Service in Shady Hollow

Hollis carries professional-grade equipment and materials from manufacturers who build for commercial crews, not weekend projects. Our sealing work uses mastic and metal-backed tapes from Abatement Technologies, filtration components from Aprilaire, and when duct repair requires replacement sections, we source compatible materials from Guardsman. For homes needing full duct cleaning before sealing, we deploy Rotobrush rotary brush systems and Nikro negative-air machines to remove the pollen, leaf debris, and wildlife contamination common in Shady Hollow’s wooded lots. We stock the materials locally, so most jobs don’t wait on parts. That matters when your system is running hard through another 100-degree Central Texas afternoon.

Common Duct Sealing Problems We See in Shady Hollow Homes

• Wildlife-damaged flex duct in attics. The live-oak canopy touches rooflines throughout Shady Hollow, giving squirrels direct access to soffits and attic vents. We regularly find nests, acorns, and chewed flex duct that has separated at joints, dumping conditioned air directly into the attic.
• Disconnected returns under pier-and-beam floors. Homes on pier-and-beam foundations, common in the older sections near the community park, often have flex duct runs that have pulled loose from boots or been crushed by settling. The crawl space draws hot, humid air into the system through these gaps.
• Dried mastic and separated metal trunk lines. The 1970s and 1980s rigid-metal systems in many Shady Hollow homes were originally sealed with water-based mastic that has cracked and flaked after 30-plus years of thermal cycling. We scrape and reseal with modern solvent-based compounds rated for the temperature swings.
• Return plenums clogged with cedar and oak pollen. Shady Hollow’s heavy pollen seasons deposit sticky material on evaporator coils that then sloughs into return plenums. When the plenum leaks at seams, that pollen-laden air enters wall cavities and recirculates through any gap in the building envelope.
