An odd situation - we have a pair of internal UPVC french doors that we want to remove. I have taken the doors off and the glass out fine and i am now faced with a problem where the doorframe is seated into the wall on all four sides by about 3 inches - left, right and top bottom. I guess they were fitted and the previous occupants had the builder render over the entry side. It looks like i would need to hack away the wall by three or four inches off all four surfaces which would need a lot of making good. I am hoping i can cut the frame in multiple places, but the frame does have a metal core. Just wondering if anyone knew how hard cutting this frame would be and if there are any weak points?
