Dryer Vent Hose Replacement in Danville, CA

What actually gets replaced when the hose goes

Is the hose behind the dryer the whole problem? Usually not. The transition hose is only the visible part. In 1980s+ two-story tracts the real run goes up a chase to the roof. We replace the flex you can see, then camera the rest. White vinyl and thin foil flex from the 1970s and 80s still turns up here, crushed flat behind a dryer shoved tight to drywall.

The replacement itself is short work. UL 2158A foil transition, four feet or less, no screws into the airstream, clamps at both ends. Then the dryer gets set out from the wall far enough that the hose curves instead of kinking. That gap is the part people lose over time.

Rigid metal retrofit is the recommendation anywhere foil flex runs through a wall or ceiling cavity. Flex inside a cavity collects lint, and nobody can see it fail. Second-floor-to-gable-wall horizontals with three or more elbows are the worst offenders.

Check the termination yourself before calling. Oak woodland backs a lot of lots here, and birds and roof rats nest at uncapped roof jacks. If the flap does not swing, the hose is not your only issue.
