After meeting such awful double glazing salesmen who quoted ridiculous amount, AGS was a breath of fresh air. The job was done to perfection and the price was amazing. In my view the best out there.

AGS installed our door and windows in 2008. We have always enjoyed good after sale service. The 10 years guarantee was worth it.

Superb from start to finish. Gave realistic and competitive quote on day one with no "wheeling & dealing", Special offers etc, etc. Explained window specification and they were as described when fitted. Quick turn around, very prompt installation and very professional and friendly fitters.

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.

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.

We wouldn't hesitate to use AGS in the future, or recommend them. They were quick to reply to our initial enquiry and Andy came to give us a quote the next evening. Andy helped us work out a solution for our back door using an aluminium frame with a single pane of glass. The job was completed to a very high standard within 2 weeks. Honest, reliable, great value and a lovely team - thank you all at AGS.
