Air Duct Repair in Elk Grove, CA

Air duct repair in Elk Grove

Pull a register and look up the boot. You want a drawband on the inner liner. Then a second band over the outer jacket. Mastic over the collar seam. Missing bands are the common failure here. Flex creeps off the boot slowly. The room goes quiet before it goes hot.

Most of this town was framed during the subdivision push. Laguna, Laguna West, the east side. Flex duct in vented attics. Check how the runs are held up. Saddle hangers, wide, spaced along the run. Bare wire cuts into the jacket. Duct lying on drywall between joists bellies out. Bellies collect cellulose and dead air. Repair means re-hanging it, not taping it.

Sheldon, Wilton and Old Town keep older houses over crawlspaces. Sheet metal down there. Joints open as the clay shifts seasonally. Roof rats and ground squirrels get into panned returns. Odor shows up before anything else does. Clear and clean first, then seal. Seal first and you lock the smell in.

One thing people miss: a furnace changeout in California triggers a duct leakage test. A HERS rater verifies it. Existing torn ducts fail at that moment, not before. Ask for the measured leakage number. It belongs on the certificate. Tape without a UL 181 mark will not hold that result.
