Floor might level itself out

Q: Providing I cut back the flooring along the walls and address the moisture issue once I determine it (as you assumed the crawl space has a dirt surface and there was no intentional source built into the crawl space for cross ventilation from what I can determine) will the cupping that has already occurred level itself back out or will I have to level it manually (i.e.- sanding)?

A: The floor might level itself out. I would give it several months to determine if it will adjust itself. If you do have to have it sanded, make sure it is tested with a moisture meter first to be sure it has returned to normal range.
