They charge 10.00 per MINUTE. The guy was friendly...he, in a friendly manner, tried to convince me that parts of my garage door needed to be replaced. I assured him that I was the one who broke the garage door and I knew exactly what went wrong. After 20 minutes of this he went to work, popped it back in the track, touched it up with lube, and, in a very friendly way, charged me 300.00. He was there for 30 minutes. He used NO NEW PARTS. There wasn't even any lifting involved. Total rip off. Unless money is no object, I would recommend anyone else in the valley.
