Dryer Vent Replacement in San Antonio, TX

What makes a dryer vent replacement job hard here

Pull the dryer out and look down. White vinyl flex is the first fail. Foil flex crushed into an accordion is the second. Both were common installs in older tract laundry closets. Neither should go back in.

Slab-on-grade ranches vent straight through a sidewall. That run is short and easy. The trouble is upstairs laundry in two-story builds. The duct leaves the closet, turns, crosses joist bays, and climbs to a roof jack. Every elbow eats the allowable length. We count elbows before quoting the path, not after.

Interior walls hide the real problem. Drywall closes over a joint that was never taped. Lint then drifts into the bay and sits on insulation. You find it as a gray halo on the ceiling or a musty smell near the closet door.

Attic sections sag between trusses. Sagging makes a low spot. Low spots hold condensate in winter and turn lint to paste. We strap rigid pipe to framing so it stays straight.

Terminations matter more than most homeowners expect. Pull the screen out of any louvered hood. Replace roof flappers that wasps or starlings have propped open. Guards go on the outside face only, never inside the pipe.
