Duct Sealing in Castroville

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

Where the Money Leaks

Duct joints, boots, and connections loosen over time — clay-soil movement in Castroville 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 Castroville summer.
