Dryer Vent Maintenance in Houston, TX

Why does one load of towels take two hours now?

Usually the run, not the dryer. Houston homes vent in a few patterns. Slab ranch homes get short side-wall runs, 4–10 ft through brick or Hardie. Two-story homes built from the 1990s onward often push 20–40 ft through the attic with two to four elbows and a roof jack. Three-story townhomes and mid-rise condos use a vertical chase. Garage-corner setups go out a sidewall or up through the garage ceiling. Manufactured homes run underfloor and exit at the skirting or rim. Each one fails differently.

Humidity here changes what we find. Lint that stays damp packs into a mat instead of a fluff. Dryer sheet residue plus moist air leaves a varnish-like film on the duct wall. A brush alone skates over that. Sagging attic flex holds condensate at the low spots, and the lint cements there. At roof jacks, pollen-bound lint glues the flapper partly shut.

We also pull bird and wasp nests out of uncapped hoods. Foil and vinyl flex crushed behind the dryer in a shallow utility closet is the other common one. That gets replaced with rigid or semi-rigid metal.

Single-family households are usually fine at 12 months. Long attic or roof-terminated runs, or homes with pets and big families: 6–9 months.
