Why Hollis Air Duct Cleaning Is Dripping Springs’s Preferred Duct Sealing Company

We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing in Dripping Springs follows The Garrison Standard: arrive inside the window, price in writing, complete the job by the book, leave the site clean. That standard matters here because Dripping Springs properties aren’t suburban tract homes. They’re 1970s ranch houses on caliche lots, or 3,500-square-foot custom builds with three zones and a workshop system that got forgotten during construction.

Our technicians are background-checked and uniformed, and phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. Every repair carries the 365-Day Done Right Promise in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. In a market where some crews skip camera inspection on long rural drives, we bring the full rig every time.

Duct Sealing Services in Dripping Springs

Duct Sealing Services in Dripping Springs address leaks in supply and return ductwork that waste conditioned air, pull in attic dust, and let cedar pollen bypass your filter. A typical sealing job for a single-system Dripping Springs home runs $450 – $850; homes with two or three systems, common in newer construction near Belterra and Highpointe, range $800 – $1,600 depending on accessibility and whether flex duct rerouting is needed.

Leak Detection and Mastic Sealing

We pressurize the duct system and use smoke pencils or thermal cameras to find leaks at joints, plenum connections, and register boots. Accessible seams get sealed with duct mastic, a water-based compound that remains flexible and won’t crack like foil tape. In Dripping Springs, we often find plenum disconnections in new builds where drywall crews bumped flex runs during finish work.

Flex Duct Repair and Reconnection

Crushed or kinked flex duct can’t be sealed with mastic alone. We reroute or replace damaged runs, reconnect boots at the register, and support the duct properly so it doesn’t sag or pinch again. This is common in Dripping Springs custom homes where 40-foot flex runs were forced through tight chases during construction on caliche-heavy lots.

Duct Insulation in Dripping Springs

Duct Insulation in Dripping Springs prevents condensation on cool supply ducts running through hot attics, a problem that peaks when outdoor temperatures hit 100 degrees and your system is working hardest. Uninsulated or poorly insulated ducts in Hill Country homes lose 20 – 30% of cooling capacity before the air reaches the register. A typical attic duct insulation job in Dripping Springs runs $600 – $1,200 for a single system, depending on linear footage and whether we need to remove degraded old wrap first.

R-8 Fiberglass Wrap Replacement

Older Dripping Springs ranch homes often have R-4 or R-6 duct wrap that has compressed, torn, or been disturbed by rodents. We remove the degraded material and install R-8 fiberglass insulation with a reinforced vapor barrier, sealed at seams with mastic. The upgrade pays for itself in reduced run times during the long cooling season.

Closed-Cell Spray Foam Encapsulation

For ducts in vented attics with chronic condensation issues, we offer encapsulation with closed-cell spray foam. This creates a monolithic seal that stops both air leakage and thermal bridging. It’s a bigger investment, typically $1,500 – $2,800 for a Dripping Springs home with a single system, but it eliminates the maintenance cycle of re-wrapping every decade.

Trusted Brands We Service in Dripping Springs

Our trucks stock parts and materials from Honeywell, Aprilaire, and Abatement Technologies, the same filtration and sealing products used in commercial HVAC work. For Dripping Springs customers, that means no waiting on a parts run to Austin when we find a disconnected Honeywell media cabinet or a failed Aprilaire humidifier bypass duct. We carry mastic, foil tape, flex duct in multiple diameters, and insulated register boots so most jobs finish in one visit. If your system uses a specialty component, we’ll tell you before we leave the estimate, not after we’ve opened the duct.

Common Duct Sealing Problems We See in Dripping Springs Homes

• Crushed flex duct in new custom builds. On caliche-heavy lots, installers sometimes force flex runs through chases too small for the diameter, creating kinks that restrict airflow and leak at the strain points. Sealant alone won’t fix these; the run needs rerouting or replacement.
• Disconnected return plenums pulling in attic air. We regularly find 12-inch or larger return ducts disconnected at the air handler plenum, especially in homes built during the 2020 – 2023 construction surge. The system pulls hot attic air, caliche dust, and cedar pollen straight into the blower, bypassing the filter entirely.
• Poorly sealed filter slots and access doors. In Dripping Springs, where cedar pollen peaks December through March, an unsealed filter slot lets allergenic particles bypass the media and coat the evaporator coil. We seal these gaps with gasketed access panels and mastic.
• Outbuilding and second-zone systems neglected during original sealing. Rural Dripping Springs properties often have a workshop, guest house, or pool equipment room with its own duct run. These smaller systems get skipped by crews in a hurry, leaving leaks that waste energy and draw in dust from unpaved driveways and open land.
