re: 100 yr old house progress

Your getting there man. Like Jeff, we could never get away with water on an outside wall now. My own house however has it in the kitchen but it’s inside the insulated wall away from the Gyprock by 4 inches. That was code sixty years ago here. We have multiple power outages for days ata time every winter here with temps going down to -25C. Frozen pipes are a reality a lot of winters for people that don’t know how to drain stuff if the power goes out.
