Dryer Vent Cleaning in Alhambra, CA

On the 1920s–30s Craftsman and Spanish bungalows here, the vent usually punches straight through a stucco wall on a short run, and the cap sits low, often right above a planting bed. Those caps take sun, dust and sprinkler spray for decades, so the plastic louvers go brittle and snap. If the duct behind it is sound metal, replacing just the cap is the sensible fix and we can do it at the time of the cleaning. We'd recommend replacing more than the cap when the wall run itself is old flex, crushed where it turns, or when the stucco penetration has been patched and re-patched and no longer holds a clean seal. Repairing a cap on a bad duct is throwing good work after bad, and we'll tell you which one you have before touching it.

Two patterns dominate. In the older single-family stock, the wall cap sits low enough that it collects San Gabriel Valley dust, spring pollen and leaf litter from whatever is planted under it, and we regularly pull out spider nests, webbing and the occasional bird or insect debris packed behind a stuck flap. That mats with lint and chokes the opening. In the 1970s–80s stucco apartment and condo buildings, the problem is different: interior laundry closets with long runs through walls and ceilings, or ground-floor shared laundry rooms where several dryers tie into common ducting. Those shared ducts build lint at the junctions and one blocked branch backs up the others, which is why a dryer in a shared room can run fine one month and take three cycles the next.
