I recently bought a house and have planned a few repairs. One of them involves adding french doors into a pre-existing doorway between the living room and family room. The doorway is very wide, so I'll need to basically "shrink" it to fit any pre-hung doors I buy. My question is, will I need to rebuild the header if it is just a single 2x4 along the top of the doorway, or can I just remove the drywall, add the appropriate number of studs to shrink the doorway to fit, and hang the door? Do I need multiple 2x4's as a header or will one suffice? I'm just trying to plan ahead.
Thanks in advance.
