Doug was courteous, mannerly and efficient. Problem for repair turned out to be that the 3rd roller from the bottom right side of the garage door (looking from outside) was out of the track. It even came out again after it was thought to have been be repaired by Doug, causing Doug to get it back in, and then tighten the vertical track rails. Hopefully this problem is now corrected, and the roller will stay in the track. A new keypad was also installed by Doug.
