Duct Sealing in San Marcos

Here is why sealing matters so much in a Hays County summer and how we do it.

Where the Money Leaks

Duct joints, boots, and connections loosen over time — clay-soil movement in San Marcos does not help — and the leaks let conditioned air escape into the attic. You feel it as a hot back bedroom and a high bill.

How We Seal It

We locate the leaks and seal them at the joints with mastic, and where the duct layout is buried or hard to reach we can seal from the inside. Then we verify the airflow improved rather than just declaring it done.

Comfort and Room Balance

Sealing usually fixes the room that never cooled, because the air that was leaking out now reaches the register. It also takes load off the system, which extends its life in a San Marcos summer.

Why San Marcos Homes in Particular

Master-planned communities like Blanco Vista and the 55-plus Kissing Tree brought a wave of new construction with builder-grade systems. Same story as everywhere — sized to a price, weak in a Texas August. We run a load calculation and fix the airflow once the warranty runs out.
