All I have to say is don't make my mistake by not getting a detailed quote in writing. When the salesman tells you what you are getting, make sure to get it in writing and, get at least one or two quotes from different companies so you have comparisons before making a decision, it will pay off in the long run. I was told by the salesman that the rollers and workings would be hidden inside a box, it is not, it is completely open. After phoning the office I was told they don't put a cover over the rollers on the inside of the garage, but if I wanted one they could make one for £500. Mmmmmm let me think about that. So now my integral garage which we use regularly throughout the day looks very pretty on the outside, but not inside.
