 If it's just a matter of this floor, why is it happening? We have two bedrooms on the upper, well, it's a ranch, but two bedrooms on this first floor as well. Underneath the carpet, it's doing the same thing. And that's not the same type of floor that we have throughout the house, obviously. There's probably plywood or something similar, too. I'm pretty sure that we think it was a decent material. But why is it just not the hardwoods? Why is it happening underneath the carpets, too?
