Who You Are Calling

A job here starts at the dryer, not at the wall. We pull the machine out, disconnect the transition hose, and check airflow at the exterior hood with a meter so there's a number to compare against later. Then the rotary brush goes in on a flexible line, driven by a drill, and we work the run from the cleanest access point we can get — usually the dryer side, sometimes the hood, often both on a long vertical. A vacuum stays sealed at the open end the whole time so the lint comes out instead of settling in your attic or laundry room. We pull the hood cover, clear the damper flaps, and clean the last few feet by hand because that's where the packed lint usually sits. Then we reconnect, run the dryer, and read airflow again. If the second number doesn't move, we tell you that and we keep looking instead of calling it done.

We work in La Mesa and across San Diego's East County and the inland-suburban band, and the housing era tells us most of what we need to know before we arrive. Prewar and 1940s bungalows were never built with a dryer location in mind. Laundry got added to a back porch, a service hall, or an attached garage decades later, so the duct is retrofit, often flexible foil, often run through a crawlspace, attic, or along a stucco exterior to whatever wall was closest. The 1950s and 60s slab-on-grade ranch tracts put laundry in the garage or an interior hall closet. Garage runs are short and usually fine. Interior closets mean 15 to 25 feet through the attic with elbows, and the elbows collect. The 1970s through 2000s two-story tract homes and condos stacked laundry upstairs or in an interior closet with the duct going vertically up through the roof. Those are the longest and worst-draining runs in the county, and they're the bulk of our calls. We work behind gas and electric units of every age, stacked units, and the tight closets that make the transition hose crush behind the machine.

Low ambient humidity and warm air mean people here don't notice a drying problem until the run is substantially blocked, so vents go unserviced far longer than they would in a humid climate. Coastal cities get marine-layer moisture most mornings that keeps lint tacky against the duct wall. Inland and foothill cities like this one pull in Santa Ana dust, decomposed-granite grit, and seasonal pollen through the same exterior termination, and that mix binds with lint into something a leaf blower will never move. Gas dryers are common across every housing era around here, which means a blocked duct is a backdraft and carbon monoxide question, not just a lint question. Cost tracks the run: a short garage shot is a different job than a two-story vertical to a roof jack that needs ladder work, or a foil retrofit through a crawlspace that has to be pulled apart to be cleaned. If we open yours up and the airflow is already good, we say so and don't clean it. That happens often enough with newer short runs. If the duct is crushed, disconnected in the attic, or foil where it shouldn't be, we'll talk about repair or a proper new installation, and if you just want to know where you stand, an inspection answers it.
