Patio doors

Recently had patio doors fitted by AGS and overall very pleased with the installation. The doors were of excellent quality and the fitters did a great job considering a 1st floor flat which made it awkward. They were very clean and tidy throughout and I would recommend AGS to friends and family. A great price.

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.
