Keep plaster walls or replace with drywall?
We're remodeling our kitchen, and need to decide whether to go down to the studs or preserve the existing plaster and lathe walls. Our house is circa 1915 and these are plaster over wood lathe with a smooth finish.
One of the four walls must come down to the studs (removing a chimney) and will then be drywalled. The others are in good condition and would only need minor patching. Somewhat astoundingly we are clear for both asbestos and lead paint in these walls so there is no real reason to remove them or leave them on that front.
Are there compelling arguments for getting rid of the plaster? Drywall guy says we will have problems with plaster cracking and should replace it all so that it matches---but then again, he's the drywall guy. We do have cracking as the house settles, but it's an old house and that seems par for the course---doesn't bother us too much. We are adding some electrical, but no new plumbing and 2/3 of the wiring to be added will be in the wall that's getting taken down to the studs anyway (which leaves one new outlet each in each of the remaining three walls).
My concern on taking the plaster out is that the wood/plaster combo may be providing good sound insulation right now, but that might not be the case...? (The three walls in question are two exterior walls and an interior wall between the kitchen and our bedroom.)
Thoughts on this? Thanks!
