If you have hardwood floors in your home, chances are you may have had to deal with water damage or perhaps you will in the future. Water damage can range from very minor - where you may not see the signs of it at all - to very serious, like when the floor is flooded with water from a broken pipe or an ice-maker hose.
Very often, the extent of the damage is determined by how long the water is on the floor before it is discovered and dealt with. Sometimes the water travels underneath the hardwood and is not at all visible from above. It becomes visible when warped boards begin to appear.
