Dryer Vent Replacement in Houston, TX

Replacing a dryer vent that has stopped moving air

Clothes need two or three cycles in July humidity. The laundry room smells damp and mildewy. Sometimes there is a scorched-lint odor, or the dryer quits mid-load because a thermal fuse tripped. That is restricted airflow. Cleaning fixes some of it. A collapsed or wrong duct has to come out.

The usual culprit is crushed flexible foil behind the dryer in tight closets. Push the machine back, the duct folds flat, lint stacks at the crease. Rigid metal replacement solves it. Joints go together with clamps and foil tape, not screws driven into the airstream, since screw tips catch lint and build a plug.

Run type drives the job. Short 4-8 ft exterior sidewall runs in postwar single-story ranches and bungalows are straightforward. Two-story subdivision homes carry 20-35 ft attic runs to roof caps, where hot-then-cool duct sweats and turns lint to paste, and elbows jog to clear a truss. Interior laundry closets in midrise condos, townhomes, and garden apartments share long horizontal chases, so the building usually controls that duct.

Terminations matter as much as the duct. Roof-cap screens trap lint. Bird and wasp nests block the hood. We clear the cap, fit a proper bird guard, then check airflow at the outlet before leaving.
