Here are some tips and a checklist for what to do in the aftermath of a flood or water damage situation:

If your property has been damaged by flooding, restoring and cleaning it up is vital. However, rushing into rebuilding can cause problems such as mold growth, insect infestations, and deterioration of wall coverings because submerged wood can absorb a lot of water. You should remove and replace all porous building materials, as floodwaters are not clean.

Before entering the property, inspect for structural and electrical damage from the outside to ensure your safety. Electrical safety is especially critical during floods, so check for fire hazards and gas leaks. Use battery-powered light sources and avoid mixing chlorine bleach with ammonia or vinegar.

Wear sturdy shoes, rubber gloves, and eye protection, and watch out for fire ants, snakes, or other animals. If there is mold, wear a respirator that can filter spores.

Start by making sure that your electricity and gas supply are turned off.

If your property has experienced short-term flooding, there are some steps you can take to minimize damage before permanent repairs are made. However, long-term flooding or wetness may ruin most interior finishes and contents. It's important to delay permanent repairs until the building is thoroughly dry, which may take several weeks.

Here are some specific steps you can take for different types of flooring:

1. Subfloors: If your plywood or OSB subfloors have been submerged, they will likely separate or swell. It would be best to replace affected sections to prevent the new floor covering from buckling. After removing the floor coverings, allow the subflooring to dry thoroughly, which may take months without a dehumidifier. Check for warping before installing new flooring.

2. Wood floors: To reduce buckling caused by swelling, carefully remove a board every few feet. If your panels are tongue-and-grooved, it's best to consult a carpenter or flooring professional. After removing the boards, clean and dry the floor thoroughly before attempting repairs.

3. Tile and sheet flooring: Remove the flooring if your wood subfloor swells or separates. (Note: A professional should only remove asbestos tiles.) After removing the flooring, allow the subfloor to dry thoroughly before attempting repairs.
