They began framing my house and unfortunatly it has rained quite a bit on the subfloor. I live in Michigan so we weren't expecting any rain in December, go figure. The material used is plywood but I don't know the grade etc, is there a way to tell by looking at the sheets? I already see some dilaminating and buckeling. Not sure if these are the right terms but basically the top layer in some areas is coming up, not the entire sheet but small areas starting at the edge. I also see some small areas that bubble/bulge upward. I'll try to take pictures. I have two questions:
1) Will this cause problems with the 3" solid hardwood flooring that is installed later?
2) Can they replace the subfloor if the walls are up? They have all the walls studded out on the first floor, can they work around these since they are nailed into the subfloor?

To replace the subfloor around the edges they will have to make cuts as the walls are built on top of the floor. For sheets not under walls a simple solution to delamination is to pry up the plywood and flip it over as the other side is probably in good shape. I'm not sure how difficult this will be if the subfloor was glued down as well.
I can't answer whether the delamination will be a problem under hardwood but for my projects, I make sure the subfloor is as perfect as possible.
