1. Remove any water soaked items from the floor

Soaked objects such as carpet, rugs and furniture has to be removed from the room and be taken outside in the sun or another area where they can dry. Ensure they are completely dry before you take them back inside. A damp carpet can cause a moldy and smelly floor as well as worsening the level of damage to the wood.

2. Soak or vacuum the water as much as possible

Immediately use towels or mops to soak up if you are dealing with small spills or puddles. For large accumulation of water, use a wet vacuum to suck up all water that is standing. Continue running the vacuum even if no water is visible on the floor. You will realize water is still collecting in the canister and you will have to continue for a while. This completely removes water even from the invisible wood pores and plank seams.

3. Clean the surface using a disinfectant

5. Use fans to clear moisture

Set large fans to face the floor, open the windows slightly for about 3 inches and door wide open. Run the fans at the highest speed to drive out any moisture in the room. Ensure your fan is clean with no dust. You could also turn on your air conditioning system without any heat. Heat may cause wood cupping and splitting especially if it has not dried completely.

6. Dry a sub-floor if you have any
