The People Behind the Work

Gulf Coast humidity is the controlling variable here. The intake air a dryer pulls from a laundry closet is already moisture-loaded most of the year, so cycles run long, lint sheds heavier, and damp lint packs into duct seams instead of blowing clear. Slab construction pushes laundry inboard. Older one-story ranches around Houston often get a short 6–12 ft sidewall run through brick or siding, which is the easy version. Post-1990 two-story builds in the master-planned suburbs put the laundry upstairs or in a center hall, forcing 20–35 ft of duct through hot attic space to a roof cap. Attic temperatures over 140 F in summer, long horizontal runs with sag in flex duct, and roof terminations with screened caps turn up again and again across this metro. Winter cold snaps are brief but sharp enough to condense moisture in roof-run ducts, and that wet lint sets up hard. Pine, oak and ragweed pollen in spring and fall, plus construction dust from ongoing subdivision build-out, loads exterior vent hoods from the outside in.

Most calls sound the same: towels taking two cycles, the laundry room hot and damp after a load, a dryer shutting off early, or lint showing up around the door seal. We come with a rotary brush on a flexible drive line, a vacuum that stays sealed to the duct while the brush runs, and an anemometer to read airflow at the hood before we start and again when we finish. The before-and-after reading is the part that matters. It tells us whether we actually moved the restriction or whether the problem is the duct itself. We work behind gas and electric units, stacked and side-by-side, pedestal installs, and the condo closets where the dryer has to come out to reach the transition. We clean sidewall runs, attic runs to roof caps, and the long center-hall routes. On roof terminations we clear the screened cap or remove the screen entirely, since that screen is usually where the blockage starts.

Sometimes we pull the line, run the camera or the brush, and the duct is clean. We say so and we do not clean it. What we often find instead is a rebuild problem: Harvey and prior flood rebuilds left a lot of replaced laundry rooms with improvised flexible foil duct behind new drywall, and foil crushes, sags and tears. That is a repair or a full new run, not a cleaning, and we will tell you which one you are looking at. On cost, a short sidewall run on a one-story is the simple job. The number moves when the duct runs 25 or 30 feet through a hot attic to a roof cap, when the dryer has to be pulled and the transition rebuilt to reach the duct, or when we find foil instead of rigid metal and the run has to be opened up. If you are not sure what you have, start with an inspection and decide from there.
