Customer scheduled an appointment because the door was not opening. Once I got on site I was able to diagnose it relatively quickly as a broken spring. Did my inspection and noticed cables and bottom brackets were rusting out and the rust was now transferring to the bottom, two rollers, typed up an estimate for the customer. The customer decided they wanted to move forward with the recommended part replacements. Once I got the door up and running it balanced well, ran smoothly, quietly, and efficiently.
