Hi - we're looking for a restorer / tradesperson for some work on the windows of our flat. The crittall windows at the front are in need of some restoration works and we need to find a good specialist. We need to take the windows right back to the metal. Burn off the layers of old paint, maybe nitromors, remove any rust completely, then put an oxide paint on - to seal and deal with the rust. Then two under coats and two or three coats of an outdoor metal paint. Does anyone have someone they can recommend please?
