I am very satisfied with the work done by AGS. From the initial phone call to the after work service, I have been communicated with professionally, the work has been done to a high standard, receipt and after service documents provided swiftly. I've got no complaints at all and would not hesitate to recommend AGS for any window replacement work.

Installation of a new rear window and door. This was the third time we have used this company and, as on previous occasions, their products and workmanship are first class.

We have used AGS a few times before and didn't regret using them again to complete the rest of the house. They did an excellent job, four large windows, one a bay, and a front door. The whole process from first call to completion was great.

The service from start to finish was extremely professional and each person from the company was very friendly and made us feel like a valued customer. We were after a colour that was about to be removed from manufacture and Tyler did his utmost to make sure we had the door ordered in time. The installation was quick, problem free and they even created a fascia at the top of the door that matched. The door looks amazing, and we have been getting many compliments. The windows were also replaced extremely quickly. We are very happy with the service from AGS and would highly recommend them!
