I just wanted to drop a note about the service I received yesterday on my dryer vent. The technicians arrived within the time quoted. set up right away and went to work. They were very fast and efficient. The lint came out like snow from 20 years of use. They cleaned up and were gone in less than an hour with my dryer working much safer. It was an enjoyable experience that could have been a nightmare. Thanks for a great job, Bob Schaub
