Great service from the start to finish. James was brilliant about explaining everything about different styles and sizes. We had the whole house done 13 windows and a French door, they were all original wooden single pane and changed to white upvc double glazing. We are very happy with the finish and the Kirk and Cam we great all week. Brilliant service and very professional would recommend to anyone.
