Since I'm not smart enough to have made myself an actual webpage yet, I decided to post a link to Webshots to give access to my "Idea File". You can access that (and other assorted photos of mine) here.
I've been doing lots of thinking about the plaster. After much research, I believe that we can do most of the work ourselves. We can patch any cracks or holes, and if the wall is absoloutely hideous, we can put up wire mesh and use joint compound to recreate a smooth wall surface. This method has already been used in the bathroom (and probably 2 of the bedrooms, as they have no wallpaper and textured ceilings).
Another option (most likely for ceilings) is a product called Nu-Wal. You might have seen the ads for it in the back of Old House Journal. Basically, it is a fiberglass sheeting that is adhered to the wall and painted. Same basic idea as liner wallpaper, but supposedly longer-lasting and designed to hide imperfections. I'm not sure how keen I am on the idea, since you're basically covering the plaster with a fake wall... Still, it's a thought, in case the ceilings are as bad as I'm afraid they will be.
The walls between the master bedroom, master closet, and the office will have to be redone, as with the wall between the office and the office closet. I'm sure I've mentioned this before, but they're made out of framing and paneling. No drywall. No plaster. Just 1/8" paneling nailed to the studs. Those will be replaced with blueboard with plaster veneer.
So... I think that will be project #1.
Project #2 will be replacing the carpet in the kitchen (yes, a carpeted kitchen...) with linoleum. Maybe that should be #1, since it will be so much cheaper...!
