I called Martin Garage Doors yesterday evening to schedule a repair. I said that it wasn't an emergency and that the door could be closed manually. I was given a time today between noon and 5pm. Roberto, the repair Technician, called at 11:30am and said he would be here in 15 minutes. He was right on schedule. He quickly identified the problem with the emergency brake, fixed the problem, and was on his way in less than 15 minutes. Roberto was very polite, professional, and solved the problem.
