AGS Ltd was recommended to us and we could se why. Andy visited to explain the options for full double glazing replacement, gave us a quote with no pressure to buy then arranged a date of installation before he left. Job completed on time. Very professional and very pleased with result. Highly recommended.

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.

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.
