Dryer Vent Replacement in La Jolla, CA

When cleaning stops working and the duct has to be replaced

Loads take two or three cycles. You cleaned the vent last year. It came back within months. That pattern usually means the duct itself is the problem, not the lint. Crushed foil behind the dryer is the classic one in La Jolla's 1950s-70s slab tract homes, where a short garage-wall run gets pinched flat when the machine is pushed back. Torn or sagged flex between joists won't clean clean. Same for flex that collects condensate. It has to come out.

Replacement means rigid galvanized pipe through the concealed run, foil transition only behind the appliance, and joints taped rather than screwed. Screws point inward and catch lint. That detail matters most on second-floor laundry rooms in 1990s-2000s two-story homes, where the attic run climbs to a roof jack and packs at the vertical rise. Damp coastal lint mats instead of blowing free, so every elbow we can delete helps more than any brush.

Terminations get replaced too. Salt corrosion seizes flapper caps at the coast. Screened roof jacks trap lint and should not be screened at all. Spring brings bird and wasp nesting in eave vents.

Condo stacked closets with shared chases are the hard case. Sometimes the honest answer is reroute, not replace.
