"A very professional, reliable company no complaints at all"

We were a little bit concerned about changing our original box sash windows for double glazed windows, as they are a very important part of the character of our house. So choosing a company that could retain as much of the original feel of the windows was very important to us.
The Original Box Sash Window Company were superb from start to finish we felt in very good hands, everything happened when they said it was going to and we were very happy with the end result (very well insulated windows, with no condensation or noise issues and that keep the original feel of the property) Several friends have commented that they would not have noticed that we changed the windows if I hadn't mentioned it.

Great company and I would highly recomend to anyone contemplating changing their original sash windows

"An open and shut case...."

We have had all the windows at the back of the house replaced and the kitchen bay rebuilt by The Original Box Sash Windows Co. From the first visit, to the surveyor's visit and the installer arriving everything went perfectly. They may not be the cheapest but they have to be the best around.
