So today my wife noticed the new floor (3 weeks installed) has a funny feel in one spot. I noticed a few wood panels look warped and cupped particularly in one area. What causes that and how to correct it. ?
Moisture can often cause that, if a spill isn't cleaned up promptly or you mop with excessive water, for example.
Likewise, if this is over a wet basement this can happen, but I would bet the issue is from the top half of the floor (in the room).
Less likely is that there is not enough of an expansion gap between the sides of the floor and the wall, and temperature changes in the room are forcing the boards into each other (though the damage in this case is quite possibly more extensive).
