AGS were recommended to me by a friend. I found them to be very easy to deal with, no hard sell. The guys who fitted them did a very professional job with no mess. I have already recommended AGS to friends.

I cannot rate this company high enough - brilliant service yet again. Outstanding from start to finish. Windows and doors are beautiful. Should I need to use them in the future if I move home, I will be using them again. I've recommended them to all my family.

The service was fantastic throughout the whole cycle. We received a great quote which had not been inflated and didn't feel pressured at all. Once the windows were ordered we had a very experienced and knowledgeable surveyor attend the house. He gave good practical advice and really added value to the process. Once we were ready to install the team of two arrived. They were again very experienced and friendly just like everyone else had been. The experience and knowledge really helped for the little things that happen on the day. All in all we found the whole company and employees of the highest standard and would recommend to others.
