Thanks for the offer, but I don't think I'll need to go that far just yet.
The flooring is the weather resistant type, of that I'm sure. I don't think the problem is deep. It appears to only be surface or just below. The floor has never been wet or even damp since the roof went on, it appears to be from just the humidity in the air from the cloud and rain we've had for the past 6 months. It has great ventilation.
