Since your dryer vent is attached to your dryer, wherever you do laundry is where your dryer vent starts! Your dryer vent could be in a couple of different places: the basement, main floor or second floor. Depending on where your dryer vent is located will determine how we clean it. Dryer vent cleaning may be done from the inside of the home (if the external vent is not accessible), or the outside of the home (if the external vent is accessible).
