With the wood exterior underneath the foam, I don't think the stud cavity will have moisture problems?

Kenneth,My wife and I lived out in York Harbor for years, beautiful state.Try a plastic barrel that actually seals, I have seen them with an o ring, hinge and clamp.This may keep the moisture out better than a metal bucket.

Hardwwod floors warp and seperate with moisture.

About a foot from the bottom up has suffered rain/moisture damage.

I would think if you used all glue and not mechanical fasteners that over time the moisture migrating through the concrete from the outside soils would cause the glue to eventually delaminate.

Mini splits have a warmer coil so they don't wring as much moisture out of the air.

A vapor barrier on an interior wall is unnecessary and actually acts to trap moisture in wall and degrade components. 

I think I would gently poke those areas and if they were not spongy, I would use the kiltz as already described.

Again, rough handling of appliances at move-in or when cleaning, and the floor is trashed.The new laminate wood flooring is not much different, except it also swells up when moisture finds its way under the pretty top surface at the seams.Vinyl commercial tile costs more than sheet vinyl, but considerably less than ceramic.

I didn't notice any low spots where excessive moisture could be accumulating or any big trees in that area (roots issue), so I'm guessing it could be a compaction issue.
