John and the team were excellent from start to finish, simple as that. They were very keen to do what was best, not only our budget but also what would suit the features of our home. John came up with some great practical solutions for us which we'd previously not considered. I would definitely recommend AGS to anyone for price, quality of windows and installation.

I had a Conservatory which was falling down. Relatives and friends would not go in it. The trader replaced all the rotten woodwork and the single glazing, replacing it with double glazing, and put a new roof on. I now have a fabulous conservatory and cannot praise the company enough.
