Identify why moisture is in your wood. Reasons could range from a leak from a pipe or appliance, high humidity in the room or excessive moisture traveling upwards from the basement below your floor.
It does no good to correct the cupping if it is just going to happen again.
Check the humidity in the room with a hygrometer (or humidity sensor). Hygrometers are inexpensive and can be found at home improvement stories.
A hygrometer will tell you whether the room has too much or too little humidity.
Correct the humidity level in the room with a humidifier or dehumidifier, if necessary.
Wait to see if the cupping goes away and the floor levels out on its own after removing the source of moisture. Use floor fans and dehumidifiers to help the wood dry.
Take moisture readings of your floor. Information about moisture readers can be found at woodfloorsonlinecom.
Sand and refinish your floor if the cupping has not gone away and the moisture reader shows the wood in your floor is now completely dry.
