A dryer pushes hot, damp, lint-laden air through a duct to the outside. Lint that gets past the screen sticks to the duct walls and gathers at bends and at the outside hood until airflow is choked. The dryer then runs longer and hotter. The U.S. Fire Administration estimates about 2,900 home clothes dryer fires a year nationally and names failure to clean as the leading factor. Chimney companies commonly offer the service because they already carry the rods, brushes and vacuums the job requires.

  • Duct cleaned end to end with rotary brush and vacuum
  • Connection hose behind the dryer inspected and replaced if damaged
  • Outside hood cleared and the damper flap freed
  • Airflow measured before and after cleaning
  • Unsafe duct materials and routing identified

Dryer vents in older Richmond houses

Houses built before clothes dryers existed were never laid out for one. Dryers end up in basements, in converted pantries and in closets added during a renovation, and the duct takes whatever path was available — a long run across a basement ceiling, several elbows, sometimes an exit through an old window opening. Every bend and every extra foot collects lint. Flexible plastic or thin foil duct, which is still found in older installations, sags, traps lint and can burn; rigid or semi-rigid metal is the safe material.

Warning signs

Loads taking more than one cycle to dry. The top of the dryer hot to the touch. A humid or musty laundry area. A burning smell. Lint around the outside vent, or a flap that does not open when the dryer is running. A dryer that stops mid-cycle. Any one of these is reason to have the duct cleaned before the next load.

Cost and frequency

Angi reports an average of about $143, usually between $103 and $184. Hard-to-reach terminations and long runs add to it. Once a year suits most households; clean more often if the run is long, the household is large or you dry a lot of pet bedding and towels. In a rowhouse or an apartment building with shared or stacked vents, ask the landlord or association who is responsible.

Dryer Vent Cleaning FAQs

How often should a dryer vent be cleaned?

At least once a year for a typical household. Long or convoluted ducts, heavy use and pets shorten the interval. Clean the lint screen after every load regardless; it is the first line of defense, not the only one.

Is dryer vent cleaning different from air duct cleaning?

Yes. The dryer vent is a single exhaust duct carrying lint to the outdoors and is a fire-safety matter. Air ducts carry heated and cooled air around the house. They are separate systems and separate services.
