Dryer Vent Replacement in Petaluma, CA

When is a dryer vent worth replacing instead of cleaning?

Ask this first: does the duct still hold its shape? Cleaning restores a sound duct. It does nothing for crushed flex behind a dryer shoved tight to a closet wall. It does nothing for sagging foil strung between joists in a Victorian basement or back porch. Lint settles in every low spot of a sag. Replacement is the fix there. So is replacing original crimped metal in postwar ranch garage-wall and hall-closet runs, where the crimps often point the wrong way and catch lint at every joint.

Rigid metal duct is the goal. Foil and vinyl flex go away. Joints get taped, not screwed. Screws stick into the airstream and collect lint. Short ranch runs of four to ten feet are usually a straightforward swap. Attic and roof-terminated runs in two-story tract homes are the harder job. Long runs, several elbows, and a roof cap packed with lint or a bird nest make it slower work.

Termination matters as much as the pipe. Unscreened wall hoods in semi-rural areas invite rodents and birds. Vineyard and pasture dust plus wildfire-season ash load exterior hoods here.

Condo stacked closets venting through a shared multi-story chase with no cleanout are a different conversation. Sometimes that is an HOA matter, not a homeowner one, and we will say so.
