The guy did a complex troubleshooting process and figured out the issue. He fixed the door and then gave me a quote to replace a different door. He did a good job comparing their prices to others and pointed out the lifetime warranty on springs and rollers as well as the fact that their installers are Mike's Overhead Doors employees and not sub contractors. The price was competitive and fair. Additionally they had the door in stock so only a 2-3 day wait. I would highly recommend Mike's Overhead Doors.
