After months of hand wringing and arguing with Julia I decided to tear the ceiling down. I started int he back and then recruited Manny Vargas to help me do the main room. Came down pretty easy. It was two layers of plaster and mesh on top of the original lath. 90 years of dust, asbestos roofing, mouse poop, and lead paint! Yum yum.
Glad we waited till it was really hot to do this.
