no - the same thing happened to us. It dries out.

No...not a problem.

As long as your GC doesn't leave it like that for years...LOL!
;)

Ours has had so much rain on it it is unreal!! Drys out faster then you would think :-)

Good luck with your home!

I assume the sub-floor is not in yet. We used 1-1/8 T&G plywood which is NOTHING like 3/4 CDX in terms of being water resistant. We knew it would be exposed for at least one entire winter, so we varnished it. It turned out to be one of the smartest things we ever did. There was one small spot that the varnish missed. The plywood completely delaminated in this one place. I'm sure if we hadn't protected it, we would have had to replace the entire floor. For a more water resistant product like 3/4 CDX, one trick is to wait for a good rain, then go out with a cordless drill and drill a bunch of 3/4" holes where the puddles are so the water drains down into the basement. I'll NEVER, EVER build another house, but if I ever do, I will definitely varnish the sub floor again.
