Air Duct Repair in Houston, TX

Air duct repair in Houston homes

Start at the register, not the equipment. Run a hand around the grille edge. A gray halo on the ceiling paint means the boot never sealed to the drywall. That gap pulls attic air and blown-in fiber into the room. Brown rings under a supply boot mean something else. Bare metal above the insulation sweats in a Gulf Coast attic. The drip lands on the ceiling board.

Cloth-backed duct tape fails here. Attic heat dries the adhesive and the collar lets go. Flex then hangs off the takeoff while the outer jacket still looks fine from the walkboards. Mastic over mesh holds. Metal strap and a drawband under it. Check that connection before anyone talks about cleaning.

Pier-and-beam stock in the Heights, Woodland Heights and Montrose puts duct in the crawlspace. Straps rot. Flex sags into dirt. After heavy rain it sits in standing water. Boots carry silt lines after flooding. Those sections get replaced.

Slab-era ranches in Oak Forest and Garden Oaks usually have one central return. Whistling at that grille is a static pressure problem. Sealing supplies downstream makes it louder. Fix the return path first, then chase leaks.
