They successfully obtained planning permission for replacement UPVC windows for several flat owners, worked with us & co-ordinated successful installation. The previous contractor has been unable to obtain planning permission. Advanced Gazling Systems went to lots of trouble in helping us.

John, the Director, was very knowledgeable and experienced in dealing with local council. He even helped us with planning application and was persistent with calling and going to council office to reason with planning officer and after months they finally approved! That's John! They organised scaffolding for all 3 flats in the building thanks to John co-ordinating the dates and it was all done with 12 windows (4 per flat) and a balcony door and all cleaned up in 3 days. The guys worked long days to get job done. Double glazed acoustic glass really keeps the noise out now. We don't hear a thing even when DLR train goes past. New windows and doors kept us warm, dry and quiet all winter. Cannot recommend John and his team more!

On 04/02/10, we had the windows and door replaced by AGS and were very impressed by the professional way our order was taken with help, then the very high quality of materials and fittings. On 30/09/15 we chose AGS again to fit windows and door to a new extension on rear with same full satisfaction.
