Dryer Vent Replacement in Cardiff, CA

Why Cardiff dryer vents get replaced, not just cleaned

Salt air is the usual culprit. Coastal dampers corrode and seize shut. Wall hoods rust at the flange and pull away from stucco. Inside the duct, marine-layer humidity from May through September turns lint into a damp paste that cements to the wall. Once that hardens on flexible foil, brushing tears the material instead of clearing it. That duct is finished. Sand and fine grit from beach households and DG driveways bind into the same crust.

The other common replacement is crushed transition duct. Postwar ranches here have short exterior-wall runs, and the dryer gets shoved back until four-inch foil folds flat against the wall. Two inches of clearance is common. Foil and vinyl come out. Rigid or UL-listed semi-rigid metal goes in, with clamps rather than tape at the joints.

Second-floor laundry closets running up a chase to a roof cap are their own job. Lint props the spring damper open. Birds and eucalyptus debris follow. Prior owners often add termite mesh or wire screening that mats solid. Screened caps are never code-legal. They get replaced with a proper damper cap.

Condo and townhome closets with 20-plus feet of concealed horizontal duct above ceilings need access cut and patched. Ask about that before scheduling.
