Surface molds grow in just about any damp location, such as the grout lines of a ceramic tiled shower. They’re easy to scrub away with a mold cleaner mixture of 1/2 cup bleach, 1 qt. water and a little detergent. In mold remediation, the bleach in the cleaning mixture kills the mold, and the detergent helps lift it off the surface so you can rinse it away so it won’t return as fast. You can also buy a mildew cleaner at hardware stores, paint stores and most home centers.
Flooring repairs typically range between $200 to $500. The type of flooring and the length of time water sits affects the costs of removal and repair. Some types of flooring are more permeable than others. For example, laminates and carpet soak up liquids and degrade the subfloor quickly, whereas hardwood can sit underwater for short periods with little damage. Most tile products are either impervious to liquids or can be cleaned and dried with little or no damage, though the area may need grout work.

Locate and repair the source of the leak. The source of the problem is usually apparent once you remove the drywall and expose the framing. If the leak source is not easily determined, consult a licensed contractor before you replace the drywall. You must repair the cause of the leak or mold and mildew will eventually reform over the new drywall. An unresolved leak may also create additional damage to framing, insulation, siding and flooring.
After a mold has been cleaned, repaired, changed over, and final-checked, it needs to be given a new status and moved to one of three areas—typically racked in holding/storage area, reset in the press, or staged as a back-up mold in a molding-cell operation. It could also go to an outside vender for rebuild or production. You should know where your molds are.
Wear a respirator or a facemask rated for black mold spore protection, and cover arms, legs and hands to avoid contact with mold spores. Use soap and a sponge to remove visible mold. If the moldy area is dry, lightly spray with water, as this will reduce the incidence of airborne mold spores during cleaning. Next, use commercial black mold removal products, which can be found in most hardware or home repair stores, to disinfect the moldy areas, in addition to any adjacent areas. If you use bleach, make sure it won't discolor the material or surface. Place all sponges, equipment and other materials used in cleaning in a heavy duty garbage bag, and if possible, remove the bag through an nearby exit as opposed to the main house, to avoid distributing mold spores.
Category 2 Water - Refers to a source of water that contains a significant degree of chemical, biological or physical contaminants and causes discomfort or sickness when consumed or even exposed to. Known as "grey water". This type carries microorganisms and nutrients of micro-organisms. Examples are toilet bowls with urine (no feces), sump pump failures, seepage due to hydrostatic failure and water discharge from dishwashers or washing machines.
