Flat rate includes cleaning from where the vent exhausts outside to where it connects to the back of the dryer (we do not clean inside the dryer itself and we cannot handle vents that exhaust out over 20ft from the ground) Very few people realize the importance of clothes dryer fire prevention. However, according to the U.S. Consumer Product Safety Commission, there are an estimated annual 15,500 fires, 10 deaths and 10 injuries due to clothes dryer fires. Several hundred people a year are also subjected to carbon monoxide poisoning from improper dryer vent setups. The financial costs come to nearly $100,000,000 per year. In some cases faulty appliances are to blame, but many fires can be prevented with proper dryer venting.
