The lint screen in the dryer door catches only part of the lint. The rest travels into the duct, where it clings to the walls, collects at every bend and builds up at the outside hood. A restricted duct makes the dryer run longer and hotter. The U.S. Fire Administration estimates about 2,900 home clothes dryer fires are reported each year, and it identifies failure to clean as the leading cause. Many chimney companies clean dryer vents because the tools and the job — clearing a duct that carries hot exhaust — are closely related.

  • Full duct run cleaned with rotary brushes and vacuum
  • Transition hose behind the dryer checked and replaced if crushed or foil-type
  • Exterior hood or roof termination cleared, including bird nests
  • Airflow tested before and after
  • Booster fans and long or concealed runs inspected

Signs a dryer vent needs cleaning

The clearest sign is time: a load that once dried in one cycle now takes two. Others are a dryer or laundry room that gets noticeably hot, a burning or musty smell, lint collecting around the outside hood, a flap that barely opens when the dryer runs, and a dryer that shuts itself off on its high-limit safety. Any of these means the exhaust is not getting out.

Long runs and roof vents in newer homes

In many Fort Worth homes built in the last thirty years, the laundry room is in the middle of the house or on the second floor, and the duct runs a long way through a wall and attic to exit at the roof. Long, vertical runs clog faster than a short duct through an outside wall, and a roof termination is the hardest place to check from the ground. These are the vents that most need a regular schedule.

What it costs and how often

Angi puts dryer vent cleaning at an average of about $143, typically $103 to $184. Roof terminations, long runs and nests raise the price. Once a year is the usual recommendation, and more often for a large household, a long duct or a dryer that runs daily.

Common dryer vent cleaning situations in Fort Worth

  • Clothes still damp after a full cycle
  • A laundry room that turns hot and humid when the dryer runs
  • Lint blowing around the exterior vent hood
  • A burning smell from the dryer
  • Birds nesting in the vent termination

Keep in mind: Cleaning the lint screen and the short hose behind the dryer is not the same as cleaning the duct. The build-up that causes fires is in the run you cannot see.

Dryer Vent Cleaning FAQs

How long does dryer vent cleaning take?

Usually 30 minutes to an hour for a typical run. Long ducts, roof access or a removed nest can extend it. The dryer is pulled out, the duct is brushed and vacuumed, and airflow is checked at the end.

Can I clean a dryer vent myself?

A short, straight duct through an exterior wall can be cleaned with a brush kit. Long runs, multiple bends and roof terminations are difficult to clear fully without professional rods and vacuum, and a brush head lost in the duct makes the blockage worse.
