I bought some pre-hung doors, intending to replace several interior doors. The problem is, the existing door jambs are shallower than usual -- I think 3.5" instead of 4.5". So if I simply remove the old doors and install the new pre-hung doors, I'll need to build up the frame or something to attach the casing. Seems like a big hassle, and not likely to look good.
So I thought maybe the best plan would be to leave the frames in place, but replace the doors. I figure:
- Remove the hinges from the existing frames
- Use wood putty to fill the spots where the hinges were (is this a mortise?)
- On the new door, measure the location of the hinges
- Use the hinges to draw a template on the existing frames
- Drill pilot holes for where the screws will go on the existing framse
- Use a router to mortise the hinge template
- Screw in the hinges
- Hang the door
I'm obviously 99% clueless so if this is a terrible plan, please let me know.
