Dryer Vent Cleaning: The Fire-Safety Chore Most Homes Skip
Fire departments respond to thousands of dryer fires every year, and the leading cause is the simplest one: lint that was never cleaned out. The lint trap catches only a fraction of what a load produces. The rest travels into the vent line, a little with every cycle, until the line is a felted tube of fuel with a heating element at one end.
The five warning signs
Loads take two cycles. The dryer is fine — the moist air has nowhere to go. Clothes come out hot but damp. Heat without airflow. A burning smell during a cycle — stop the dryer and treat this one seriously. The laundry room feels humid or smells musty while drying, meaning exhaust is leaking back indoors. The exterior flapper barely moves while the dryer runs, or is visibly matted with lint.
Why long and roof-exit vents clog worst
Every bend and every extra foot of vent line slows the air and gives lint a place to settle. The long runs and roof exits common in newer Maryland construction clog fastest of all — and because they are out of sight, they are the ones that go a decade without attention.
What a real cleaning includes
Not a brush on a drill for the first three feet. A proper job measures airflow at the exterior cap, runs rotary brushes the full length of the line under vacuum, clears the lint trap housing and transition hose, checks every connection, and measures airflow again so you can see the difference. It takes under an hour for most homes.
The annual rule
Dryer manufacturers and fire departments agree: clean the vent line once a year. Put it on the same mental list as the chimney sweep.
