One of the cables snapped and my garage door dropped off the rails bending the tracks. I was sure it would be a lengthy & costly repair. Nolan showed up and looked it over and said it would be about 30 minutes and $135. In my mind I could NOT see how a quality job could be done so quickly. Sure enough in about 30 minutes he repaired it and had it running great for $149 (had to replace a damaged rolling pin & bracket). Now that's a professional! It was great to be able to get out of the garage again. Thanks!
