Hi, wonder if any one can help. Having been quoted £2900 to replace our bay window with pvc, am now considering refurbing it and having double glazed panels added. The window is in 3 parts, and is approx 208cm in height, with its central glass panel (with sash fitting) being 88cm wide. Am hoping someone has had this done and can offer a ballpark figure before I go down the pvc route. Many thanks in advance!
