Re: What to do with these walls?
by no means would i ever consider simply letting the electrician do his thing then repair the drywall or skin over it when the kitchen needs updating. god only knows how many things might have issues with them from the insulatin, plumbing, electical and range hood venting.. even though it will cost more. things will go more smoothly and there is much more peace of mind knowing that all the mechanical is up to the latest codes.
btw the only time i go over existing walls or ceilings is when there is stipled ceilings or wallpaper that the homeowner wants to do away with, these are both nothing more than cosmetic things. it takes much longer to strip the wall or ceiling then feather out gouges in the wall than what it takes to put up a few sheets of board then tape them
fire up the saw and make some dust
