There over 15,800 reported dryer vent fires per year.  The lint in a dirty dryer vent and heat from a dryer during use is a dangerous mixture.  Still today we find dryer vents hooked up using hazardous plastic connector hoses meant only to vent bathroom exhaust.  During a dryer vent fire this hose quickly melts exposing house framing and walls to open flames.

This is an example of a crushed exhaust hose.		This vent is in serious need of cleaning.

An improperly installed and dirty dryer vent is not only hazardous, it is also highly inefficient.  Many customers say they have to run their dryer two or three times for one load of laundry.  They can't understand why the dryer used to work fine and now doesn't.  Most times the reason is the dryer vent being dirty and/or deteriorated.
