Dryer Vent Installation in San Diego, CA

Why dryer vent installs fail in San Diego homes

Most vents we replace were never built to survive a pushed-back dryer. Builders ran flex foil to the nearest wall and called it done. Shallow garage alcoves leave no clearance behind the machine. The foil crushes flat the first time someone slides the dryer home. On 1950s ranch tracts the original run often went under-slab or through-wall, where lint settles and stays. Two-story tract homes got long vertical roof-terminated runs with elbows that pack solid.

A proper install is rigid metal, 4-inch, male ends pointed downstream. Joints get foil tape, not screws. Screws hang into the airstream and snag lint. Shallow alcoves get a recessed box or periscope so the duct never gets crushed again. We support the run so it cannot sag into a lint trap.

Terminations decide a lot. Screened hood caps invite bird nests and belong off. Stucco sidewall hoods need a flapper that still moves, not one painted shut. Roof jacks need a damper that seals against marine layer moisture. Santa Ana grit collects in the last few feet regardless.

Every elbow adds effective length. Shortening the path beats upsizing the dryer. After install, plan cleanings around 12–18 months, sooner for upstairs laundries.
