Dryer Vent Inspection in Berkeley, CA

What a dryer vent inspection actually involves

First the dryer gets pulled out. We look at the transition hose behind it. In most Berkeley homes it is crushed flat against the wall. Then we open the lint screen housing and check for dryer sheet residue, which glazes the mesh and blocks airflow you cannot see. Next we go to the termination. Outside, the hood flapper either swings free or it does not. Lint-stuck flappers are common on low garage-corner hoods in San Leandro and San Lorenzo tracts, where shrubs and stored boxes sit right against them.

Then the run itself. We measure length and count elbows. Pre-1940 homes in Berkeley, Albany and North Oakland often have long basement or under-house runs with original foil or white vinyl flex, sagging between joists. Each sag holds lint and water. A camera goes in where the run allows.

Fog-season air matters here. Damp intake air condenses in cool duct sections, and wet lint cakes instead of blowing through. That is why elbows clog first.

Gas dryers in basements and garages get an extra look. A restricted duct can push combustion gases back into the room.

Most households benefit from annual checks. Roof-cap runs and heavy pet-bedding loads need it sooner.
