Keep Dryer Vents Free From Blockage

What causes a clogged dryer vent?

Simply stated, a clogged dryer vent is caused by the build-up of lint in the dryer ventilation system.

Many new homes built today have dryers located away from an outside wall. These dryers tend to be vented longer distances creating more bends in the vent through the home. The additional length creates more places for lint to collect or for animals and birds to hide.

Dryer vents are often made from flexible plastic or foil duct, which may be easily kinked or crushed where they exit the dryer and enter the wall or floor. Ducts made of this material are more likely to sag and let lint build up at low points than ridge metal or UL approved flexible metal ducts. Poorly connected internal ducts can also trap lint. Screens or cages at the duct termination are helpful to prevent animals from getting into the exhaust from the outside, but if they are not properly cleaned and maintained they can also become clogged and restrict air flow.

Clogged vents may be a safety hazard when lint is left to accumulate in the ventilation ducts. When vents are professionally cleaned they can provide energy efficiency and cleaner indoor air quality.
