Gary called to say he could come early which was great. He diagnosed our multiple problems with the motor, the drive chain mounting and stripped bearings and pulleys. He recommended replacing all moving parts which was pricey but the right solution to problems that had been building for a few years. He estimates the time needed to do the repairs. He had all the parts in his truck. He finished everything a half hour earlier than projected. We basically have a new system with a belt drive so it’s quiet, an outdoor keypad, motion detector light and a door lock capability. It’s an upgraded system with warranties. I knew this would be needed sooner or later. Gary did a great job making it happen efficiently. I highly recommend Precision Garage Door and their technician, Gary.
