My garage door was opening on its own. I checked Angie's list for a repair service and found your advertisement. The door was bowed and the rollers have fallen off before because of the tension the bowing caused. The price was good so I signed for the service hoping I could kill two problems at the same time. Because of door opening problem, they agreed to come the next day to do the service. The entire experience was beyond expectations. The problem was the sensor board which he replaced along with doing the service. I highly recommend Precision Overhead Garage Door.
