We are very sorry for the water damages and any inconvenience you and your parents have encountered with replacing the cabinet, Tammy. There should be 15/16" of space between the top of the door and the bottom of the drawer facing. Please, at your earliest opportunity, discuss your purchase with your local Home Depot as they may have viable reorder options or solutions for you. We wish you all nothing but the best and hope that you are having a good day.
