Dryer Vent Replacement in Houston, TX

Replacing a dryer vent in Houston homes

Towels come out damp. Two cycles, sometimes three. The laundry room runs hot and smells faintly burnt. That's a vent problem, not a dryer problem. Most of the time the duct itself has failed, and cleaning only buys a few weeks.

Replacement starts with measuring equivalent length. Every elbow counts against the 35-foot limit. A long attic run with four elbows to a roof jack often blows past it on paper. Short runs behind garage dryers in 1950s-70s ranch homes have the opposite problem. The dryer gets shoved tight to the wall and the flex duct folds flat behind it. We replace vinyl and foil flex with rigid metal through the run, keeping flex to the short transition piece only.

Roof jacks are their own job. Screens trap wet lint. Birds nest under flapper hoods. Screens should come out, not get cleaned over and over.

Attic sections sweat during winter fronts. You will see drip stains on insulation below the duct. Back-drafting humid air into a laundry closet shows up as mildew spotting on drywall near the ceiling. Both mean the termination or the joints failed.

Three-story townhome stacked runs and shared condo wall chases usually need interior access cut. That decides most of the work involved.
