It's possbile it's structural, but not that likely. It's very
common for floors that were done fast and cheap to have this problem,
which makes noise abnd is very annoying, but doesn't mean the
structure isn't sound or is in danger of failing. To be done
properly, the plywood should have been glued with construction
adhesive, as well as screwed or nailed (screws are better). If done
improperly, you have this problem, but I doubt it meets the definition
of structural in new home warranties.

When the floor was screwed down, did they put screws no less than 6"
apart along all the joists? In this difficult case, I'd put them
every 4" If that doesn't solve it, then depending on what sound
remains, I might consider opening the ceiling below, depending on
area, etc, so that you can inspect the suspect joists hangers,
nailing, etc. Taking out the ceiling might be easier than removing
the flooring.

When the builder came out to see the house he was with the inspector,
a structural engineer, from the warranty company, who said the joists
were sound. You are correct, this did not meet the definition of
structural defect in the home warranty.

When our neighbor screwed down the floor the second time, he put tons
of nails in the subflooring, at least 6 inches apart or even closer
together.

I am just baffled by this problem. Could humidity play a part in it?

I am going to start calling more contractors to come out and look at
it again. But the last time we were calling around, very few were very
interested to even come out and take a look at it. The one guy who did
really wasn't too sure what to do about it.

Thanks for all the input!!
