Flood Damage Restoration

--------------------------------------------------------------------------------

Flooded homes should be thoroughly dried out, a process that may take several days or weeks.

Wet carpet and padding should be removed and discarded.

Porous materials -- those that absorb water -- such as sheetrock, some paneling, fiberglass insulation, cellulose insulation, mattresses, pillows, wallpaper and upholstered furniture should be discarded.

Sheetrock and other porous wallboards should be removed to at least 12 inches above the water line. Check for wicking, the upward movement of moisture to higher levels.

Clean wall studs where wallboard has been removed and allow them to dry completely.

Floors, concrete or brick walls, countertops, plastic, glass and other non-porous materials should be washed with soap and water and then with a solution of one to two cups of chlorine bleach to a gallon of water and allowed to completely dry.

Wear rubber gloves and eye protection when using bleach and make sure area is well ventilated. Never mix bleach with any cleaning product that contains ammonia. Consider using an N-95 rated dust mask if heavy concentrations of mold are already growing.

Materials that cannot be effectively cleaned and dried should be placed in plastic garbage bags for disposal.

Launder clothing, sheets, and towels.

Valuable items such as books, wood furniture, or papers should be cleaned or discarded. Saving damaged items may require hiring professionals such as conservators who are familiar with cleaning and restoration techniques.

Check your air conditioning and heating systems for damage. Discard water-damaged filters. You may wish to hire a professional to inspect your system.
