Something jammed the the garage door to the shed at our church so it would not open. I had a great experience years ago with Rainier Garage Door when they serviced the garage door at my house, and they did a quality job again. Robert arrived in the specified time window and even called ahead to give a more precise arrival time. He quickly assessed the problem, got the door moving again by aligning the guide wire, but then went the extra mile to make sure it ran smoothly. He noticed there was a gap on one side when it was closed, so he adjusted the door to close more evenly. He lubricated all the rollers and spring to ensure it would move more easily, and now the door stays all the way up. He noticed the guide rail was crooked on one side and straightened it so now the rollers are not strained or pulling out. He installed extra screws on the bars holding the rollers to the door since from experience he knows they have a tendency to pull out. He also added extra screws so the weather stripping was tight on the bottom of the door. He noted that the spring was old and could break soon, but no pressure to replace it, so I left it for now. Very friendly and knowledgeable. I would recommend Rainier, and will keep using them in the future.
