Expansion in partical board flooring cont.....?

Question

There is nothing wrong with the laminte, infact we will be able to re-use it once we replace the sub floor, its not expansion, its a LARGE "bump". I hope that its the one about absorbing moister from under house, but it seems so weird that its only happened there. We already had a leak in the bathroom and replaced it with plywood, and we'll be doing the same in the kitchen, and I guess now in the living romm!

Answer 1

It may have nothing to do with moisture. Have you had unusual weather lately? It could be expansion and contraction thermally.

Answer 2

Condemned property?
