My Liftmaster opener failed. I opened it up hoping I could fix it myself, only to find shredded gears. Without the time or knowledge to work on it, I called Fastest garage door around midnight and left a message. He called me first thing in the morning and set up a visit a few hours later. Tech quickly made the repair and helped me to understand what caused the problem and how to prevent it from happening in the future. I appreciate the helpful advice, reasonable price, and timely service. I will call Greensboro Fastest garage door in the future should I have any more trouble with my garage door. Thanks guys!
