Dryer Vent Repair in Cardiff, CA

When does a dryer vent need repair instead of another cleaning?

Ask this: does the clog come back fast? A vent cleaned last year that clogs again usually has a duct problem, not a lint problem. In Cardiff the common culprits are physical. Original flexible foil or plastic duct still in place on short 4-8 ft garage-wall runs in postwar single-story homes. Crushed foil behind pedestal-mounted washer and dryer sets in tight closets. A corroded exterior flapper hood stuck part-open from salt air. Cleaning does nothing for any of those.

Repair work here is mostly duct replacement and termination work. Foil and plastic get swapped for rigid or semi-rigid metal. Interior seams get foil tape, never screws, since screw tips catch lint and start the next clog. On 20-35 ft attic runs from second-floor laundry rooms in 1990s-2000s tracts, we look for sags. Lint settles at the low points and stays there. Damp coastal lint cakes rather than blows through.

Roof jacks get their own attention. A clogged termination screen is not repairable in place and the screen usually should not be there at all. Sidewall and soffit terminations on stacked condo closets need a working backdraft damper, or inland dust gets pulled back in.

What makes a repair not worth doing: an unreachable buried run with no attic or crawl access. Rerouting beats fighting it.
