I contacted B & M Garage Door, (as well as two others), on line and the responded next day, the others never did get back to me.
They showed on on time, within the 30 min. window, (they actually called to say they were going to be a few minutes late due to traffic). The repair; a spring replacement, was completed within a hour and the price was exactly what they estimated on the phone, I commented that the door was a bit noisy, Ed, the technician recommended replacing the rolls and the Garage door is almost silent. Excellent Job, great value. Ed was personable and friendly. On Time - On Budget - On the Mark.
