Good morning, Cafe. Thanks for the coffee, Shad.
Had a good work day at mom's house yesterday. I need to pick up the windows and a few supplies today and have DH help me wrestle the tub/shower surround out of the bathroom. I can then finish removing all the second layer drywall and the first layer in all the areas I'm going to tile.
I was originally going to set the wall tile outside the shower stall on the original drywall but decided to just take it down when I saw how badly damaged it was. I started at the bottom and it just crumbled in my hands. The back of the wall was covered in mold. Once I had the wet wall interior exposed, I could see more mold growing on the back of the drywall behind the kitchen sink base cabinet so I cut that out too.
Once I clean it all out, I'll wrap up all the cold lines with insulation so they don't sweat in there anymore. And of course install green board instead of standard drywall when I start rebuilding.
I'm REALLY glad that I decided to gut to the studs and will have all that nastiness OUT of mom's house.
