Hope my terminology is correct - I am a newbie at door replacement.
I have a weird sized exterior door in my house that I need to replace as inexpensively as possible. The existing door slab is 34" x 81¼" - inside opening of the door jamb is 34½" x 81½".
I can get an inexpensive prehung door that is 32" x 80", and the outside of that jamb measures 33½" x 81½"
Would there be a problem with mounting this door into the existing door jamb?
The existing door jamb is plastered in, the rough opening frame seems to be about 3/8" on each side and 1" on top.
In order to use that framing (which I would prefer not to do), I guess I would have to chip out the ¾" thick of plaster all around the existing door jamb that I am proposing to use as a rough opening. Clear as mud?
