Dryer Vent Inspection in Houston, TX

What a dryer vent inspection actually involves

The dryer gets pulled out first. We look at the transition piece behind it. Foil and vinyl flex crushed in a shallow utility closet is the most common find. Then the duct gets measured and mapped. Run type matters more than anything else. A 4–10 ft side-wall run through brick or Hardie on a slab ranch behaves nothing like a 20–40 ft attic run with three elbows ending at a roof jack.

Next comes airflow at the termination. We watch the hood or roof-jack flapper while the dryer runs on no heat. Weak flutter means a restriction upstream. A camera goes in where the run allows it. In attics we walk the duct looking for sagging flex holding condensate, because that sag is where lint cements into a damp mat.

Houston adds its own failures. Pollen binds to lint on screened wall hoods. Uncapped hoods take bird and wasp nests. Dryer sheet residue plus humidity leaves a varnish-like film that brushing alone will not lift.

You can pre-check two things. Time a towel load. Stand in the laundry room afterward. Two hours and a hot room usually means the duct, not the dryer.
