Live in a home built in 1920's. Balloon framing. Just pulled down kitchen ceiling. Want to do room over in drywall. Do we rip the plaster and lath down on the walls. Heard that studs may be uneven. Is this true in all cases. I would like to DIY but not sure I can do it if I have to shim out walls to hang the drywall. Had a contractor just look at it and he recommended drywalling over plaster. I've been watching Holmes on Holmes and he usually recommends always taking old out before starting new. Any suggestions greatly appreciated. I did check other threads first. Thanks.
