This past summer, I changed my 1950's ranch into a 2-story, which was a major project. (And no, I still don't live in the house yet). While the roof was off and the 2nd story was being added, rain had gotten the old 1/2" to 9/16" plywood flooring wet. The plywood sits atop 3/4" solid wood planks running at a diagonal, and all of the original subfloor is still in place.
Now that it's winter and getting dryer, I'm noticing that the plywood is crackling as I walk over it, and I think it's delaminated in many areas, even though, from the surface, it looks fine. I would like to finish the floor with 3/4" hardwood, with tile in the bathroom and possibly kitchen, but I'm concerned about the crackling plywood. The noise is more of a crackle than a creak or pop, but I'm thinking that the sound may still transmit through the hardwood and/or tile when we walk over the floor. I'd be putting backerboard down under the tile, but does anyone have any experience with delaminated plywood? Also, as a side note, I've been told by a high-end builder that they don't use backerboard under tile, but rather, just another sheet of plywood. What's up with that? Well, maybe that's another thread.
Anyways, is there anything I can do, other than to just replace all of the old plywood (leaving the 3/4" solid planking), and putting down new? It's about 1600 square feet of old floor, and that amounts to a bunch of money for "new" underlayment, but I also don't want to be kicking myself later, after spending even more on the finish floor.
Thanks!
