I had site finished oak strip flooring in my previous house. I had a bunch of water leak from my freezer because the door was left cracked open for three days. The floor swelled up. I left the floor to dry for a good six months and then someone came in with a moisture meter and tested the moisture content. They declared it was dry enough to refinish. I had it refinished and within six months the floor was cupped the other way. The floor was not completely dry when it was re-finished.

I don't know if I would do wood flooring again in a kitchen.
