How We Seal Ducts in Little Elm

Duct sealing pairs naturally with an AC tune-up in Little Elm, and you can see all our duct sealing options or explore the full lineup of Little Elm HVAC services.

Mastic, Not Tape

We seal joints with brush-grade mastic that holds in 130-degree Texas attics, instead of tape that peels in a few summers.

Measured Results

We check airflow and static pressure before and after so the energy savings are real, not just claimed.

Lower Summer Bills

Sealing leaks keeps your cooled air in the ducts, which can cut energy waste by up to 30% on a Little Elm system.

5-Year Sealing Warranty

Our duct sealing work is backed for 5 years, with Aeroseal-style internal sealing warranted up to 10.

Sealing Leaky Ducts to Cut Energy Loss in Little Elm

A typical home loses 20 to 30 percent of its conditioned air through duct leaks, and in Little Elm it is often worse because builder-grade tape from the mid-2000s building boom has dried out and let go in hot attics. Sealing those gaps keeps the cooled air inside the ducts and going to your rooms, not into a 130-degree attic.

We seal accessible joints with brush-grade mastic that bonds permanently, and for ducts that are hard to reach we use an Aeroseal-style internal process that seals the system from the inside. We measure airflow before and after so you can see the difference. If a run is actually crushed or disconnected rather than just leaky, that is a job for our duct repair and sealing service in Little Elm, and sealing also helps the dust and moisture handled by indoor air quality services.
