Hello!
I discovered that the ceiling of the laundry room (which becomes the floor of one of the guesthouse bedrooms) is made of pressure-treated wood. They seem relatively "new" as they are in good condition. I have heard/read that this should not be enclosed behind walls, ceilings, and floors. How important is it to replace them, and is it something that will "definitely" become a problem later on? Is it worth spending the money and time to replace it?
What would you have done?
