Dryer Vent Cleaning in Alamo, CA

What a dryer vent job looks like in Alamo

The dryer comes out first. We pull the transition hose and check it before anything else. Then a rotating brush goes down the duct on a flexible rod. Air pushes lint ahead of the brush. We work from the laundry room toward the roof jack, then back down from the termination. The screen or damper gets cleared by hand. Dryer goes back, cycle runs, airflow checked at the exit.

Alamo makes that longer than most towns. This is unincorporated San Ramon Valley, south of Walnut Creek, with large-lot custom homes. Many are 1960s–80s ranch and split-level. Laundry rooms sit away from exterior walls, so the duct runs through the attic 25 to 40 feet to a roof jack. Two or three 90-degree elbows are common. Some newer two-story builds on hillside lots off Danville Blvd and Stone Valley carry a booster fan mid-run.

Local weather takes a toll on that duct. Oak-covered hills drop heavy spring pollen and summer dust. Valley summers run hot and dry, over 95F. Winter nights go cold and clear, and uninsulated attic duct condenses exhaust. Damp lint cakes instead of blowing through.

Check it yourself. Stand outside during a cycle. Weak or cold air at the roof means the run is loaded.
