Very happy with the service from AGS. Quote was very competitive and they were able to install a new kitchen door and window within two weeks of my placing the order, which was much faster than I had expected. They did a very neat job and left the kitchen clean and tidy. Dealing with them was easy with no pressure to buy. Originally asked them to quote based on the recommendation of one of my neighbours. Cover a reasonably wide area as we live in London N10
