I read the two other reviews yesterday and called Able Garage Door this morning on their good advice. When I told Tim I had one roller broken on my door, he tried to tell me how to fix it myself to save the price of the service call. But having no experience with this kind of repair I asked him to come fix it anyway. He arrived in just 45 minutes from the other side of town. He fixed the door and oiled everything on it. It runs smooth as silk now. Tim was very polite and professional and I highly recommend him.
