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.
