Ceiling in 1920's house help
We bought an old house and can only afford to get the big ticket items done professionally. I plan to do a lot of repairs myself. yesterday, I wanted to see what was under the Styrofoam tiles in the laundry room. The adjacent mud room has the original Beadboard. I could tell by looking at the crown molding (if that's what they called it, not fancy) that the laundry room ceiling was about 2 inches lower. With my trusty scraper and drill I started removing the tile to find sections of wood and particle board screwed in. I pulled away a piece of particle board and was showered with what I think is insulation. I have included pictures to get some advice. The particle board is separating and the insulation looks old. Should I pull the whole thing down and start over? New insulation? The room is about 25 square feet.
