How long does it take for cupped floors to dry?

As the wood is expanding during the summer, moisture can seep into the wood grain, which will settle and not come out easily.

Why are my floors buckling?

Floor buckling happens most often after a floor has been flooded for an extended period of time.

What does cupping look like on a hardwood floor?

What does cupping look like on a hardwood floor? When moisture interacts with a hardwood floor, the side of the boards closest to the moisture expands. This expansion can be in the form of cupping (the center of the board is lower than the edges) or crowning (the center of the board is higher than the edges).

Why do I have cupping on my Kitchen Floor?
