AGS supplied and fitted windows, door and patio doors for our extension. We have used them before and both times found the service and quality to be very good indeed. They are a family company and really care about what they do.

We have used AGS twice to fit a front door & side panel (June 2016) and a year earlier to fit five windows, including a bay window. Excellent service and very refreshing to not be pushed into a decision immediately (I have found other double glazing salesmen very pushy). John is very easy to talk to and incredibly helpful. We are very happy with our windows & door and would use AGS again.
