We've had A1 Garage Door Service come out a couple times to diagnose and fix our garage door that was working intermittently. Daniel came out and was very professional and explained what the problem was. He told us that the garage door springs were broken and the door opener (motor) was pretty old and might need to be replaced soon. We opted to just replace the springs initially because we were trying to save some money. A few months later our motor died (as Daniel anticipated) and he came back out to replace it with a new motor.
Each time, Daniel was prompt, professional, and knowledgeable. Would definitely recommend A1 Garage Doors to a friend.
