Dryer Vent Hose Replacement in San Antonio, TX

What we find behind the dryer, and what the hose can't fix

The hose is not the duct. It is the connector from dryer collar to wall stub. People call for a hose and have a duct problem. The two fail differently, so look at both.

Patterns repeat by house type. Postwar ranches on raised foundations vent down and out a rim joist. Those runs sag between joists and hold lint at the low spot. Split-levels stack the laundry mid-flight and push duct up through conditioned wall cavity. Second-floor laundry in newer subdivisions runs long and ends at a roof cap. Older homes with laundry in the basement often vent through a window infill panel. That panel is usually plywood with a lint-choked louver.

Replacement is UL-listed semi-rigid aluminum, cut to the true gap. No white vinyl. No foil accordion stretched and coiled. Clamps go at both collars, no screws in the airstream, since screw tips snag fiber. A pedestal washer sliding back crushes hose flat, so a close-clearance box buys depth.

Check it yourself first. Run the machine on heat and hold a hand at the exterior hood. Watch whether the damper flaps open. A steady push means the hose is your issue. Barely moving air means something downstream is packed.
