I had a large extention fitted to the back of my house. It was completed in mid March and it looks fantastic and I've had no probelms with it so far. The aftercare is very good, they have keept in touch making sure everything is still good and that no prblems have arrisen. I would highly recommend them to anyone.

We had a conservatory built 4 years ago by them and they did such a good job the first time, we've had them back a couple of weeks ago to fit a second conservatory for us. They cleaned everything up afterwards and were always on time. Very friendly and efficent workers.
