Even small amounts of water left on wood floors can cause wood to swell and eventually become damaged if not properly dried. Leaks from a water heater or a plumbing problem can damage wood floors.
How to Dry Wood Floors
Mop up as much of the water as you can. Wring out the mop in a mop bucket when the mop is saturated and then mop up more water.
Open all windows and doors and use circulating fans in the room to provide good air flow through the room.
Place dry towels on the floor to absorb moisture. Stand on the towels and move them over the floor with your feet, or kneel down and use your hands to rub the towels over the floor. Remove the damp towels and replace these with dry towels and repeat this step.
Wood floors may appear dry when they are still moist. It may take several hours for the floor to dry before you can close windows and doors and turn off the fans.
