The wood flooring in my parents kitchen was refinished one to many times and they now have to replace the floor.
They have hired a contractor and he has suggested that they install the new tongue & groove hardwood flooring directly over the old hardwood flooring. My parents have told me that the contractor will be installing the new floor perpendicular to the old floor. The contractor has told them that this is perfectly fine. I think that this is a classic cross grain situation and when the floor tries to move they will end up with a horrible mess.
What does the contractor know that I don't?
