Dryer Vent Installation in Houston, TX

Why dryer vent installation goes wrong here

Most failures start at the layout, not the duct. Builders in 1990s–2000s two-story subdivisions put laundry upstairs and ran the exhaust through the attic to a roof jack. Add two to four elbows and the equivalent length passes the 35 ft limit fast. In 1950s–70s ranch homes the opposite problem shows up: a shallow utility room or garage wall, with the dryer shoved tight and the flex duct crushed flat behind it.

So the first step is counting elbows and measuring, then deciding whether the run should move at all. A short exterior-wall path beats a long attic path almost every time. In three-story townhomes the stacked vertical chase is often the only option, which makes duct quality matter more.

We install rigid metal, joints taped rather than screwed, since screws catch lint. Attic sections get slope and support so winter-front condensation drains out instead of pooling. Shallow closets get a recessed dryer box so the duct does not kink.

Terminations matter in this climate. Roof jacks with screens clog with wet lint and nesting birds. A hooded flapper that actually closes keeps humid air from back-drafting into the laundry room and feeding mildew on drywall.
