Many homes built on Long Island, and I imagine elsewhere, after World War II used steel framed interior doors. Does anyone have any experience in changing these. The steel frame is connected to the studs via tabs nailed to the studs. I was able to use a sawsall to cut these tabs and to cut the frame into sections. The problem is that the steel frame was installed on the sub floor and then the finished oak floor was installed over the nailed tab. There doesn’t appear to be any way to reach the tab on the sub floor without cutting away the finished floor. The removal and repair of the finished floor took more time than installing the new door. I also found that I had to go to a 32″ wide door to replace the original 30″ as the steel frame was very wide. If I blocked it out for a 30″ replacement the trim would not reach the sheetrock.
