I have a 120+ year old home that has plaster ceilings. The previous owner papered over the plaster then painted (they did this on the walls too). The paper has cracked in some spots, and in others the ceiling is bowed and cracked, presumably from the plaster pulling away.
I had a contractor out who wanted to just place 3/8 drywall over the plaster and skim. Since I was putting molding around the edges I told him he didn't have to tape the edges. His quote was $1200 without painting. Room is 17 x 14. Seems pretty high to me, plus I wasn't impressed with his idea of just hanging new over the old. First of all, how is he going to be sure he's just not screwing into the plaster lathes?
Anyway, I'm going to pull down the old ceiling, inspect the beams, which I'm sure need to be sured up, and hang new drywall. All of this to ask, do I need to skim over the whole ceiling?
