Dryer Vent Installation in Houston, TX

Why dryer vent installs fail in Houston

Most bad vents here started as a builder shortcut. Flexible foil got stuffed behind the dryer. The closet was tight, so the duct kinked. In a two-story subdivision home that foil then climbs 20 to 35 feet through the attic to a roof cap. Attic air is hot, then cools overnight. Moist exhaust condenses inside the metal. Lint stops being fluff and becomes paste. Elbows added to clear a truss pack solid first.

A proper install uses rigid metal with a smooth bore, joints running with the airflow. Male end points downstream. Foil tape, not screws. Screws catch lint and build a dam. Seams sealed. Supported so the run does not sag between joists. Short sidewall runs in postwar ranches and bungalows are easy wins. Attic runs need the straightest path we can find, not the path the drywall crew left.

Termination matters as much as the duct. Roof caps in Houston collect bird and wasp nests. Screened caps trap lint behind the mesh. We install a damper-style cap with a bird guard and no screen.

After install we verify airflow at the hood. If the run can't be made short enough, we say so before cutting anything.
