Water damage is one of the few legitimate threats to hardwood floors. All the worse because flooding is often not covered by most insurance policies.
Wooden floors suffering some small scale water damage can often be repaired, though it depends on the extent of the damage and the type of water.
Though clean water flooding is very inconvenient the floor can often be recovered. Wood will quickly soak up water when flooded, and this water is slow and difficult to remove. If the surface water is quickly drained away the remaining water, which has soaked into the timber surface, can be removed with absorbent material and air circulating fans.
If the water that is soaked into the wooden floor is left to long there will be problems with mould, mildew and fungus. Once this has set in the floor is irreparably damaged, and the room will probably cause health problems.
If the floor can be dried in time, so that there is no mould or mildew, it can be restored. But the water will probably have caused swelling and buckling in the floor surface, making the whole floor uneven.
Re-sanding can restore a wooden floor to virtually new condition, removing the uneven surface left by clean flood water.
