DRYER VENT CLEANINGS ARE VERY IMPORTANT!
House fires caused by dryers are far more common than are generally believed, a fact that can be appreciated upon reviewing statistics from the National Fire Protection Agency. Fires caused by dryers in 2005 were responsible for approximately 13,775 house fires, 418 injuries, 15 deaths, and $196 million in property damage. Most of these incidents occur in residences and are the result of lint buildup in your dryer vent and in and around the dryers casing.
Below pictures shows you before and after of your Lint buildup before and after as well as the lint buildup inside the casing.
