Our garage door opener is eight years old. It still works and didn't need to be replaced. I found All Access Garage Doors on Angie's List, where they're highly recommended. The $65 tune-up included: replacing the brackets so our garage door no longer shakes back and forth when it opens/closes, tightening loose wires by adding wire nuts and placing bare wires back inside the walls, and tightening wires on the wall button inside the garage. He took 30 minutes and accepted a check -- sweet!
