During a flood cleanup, the indoor air quality in your home or office may appear to be the least of your problems. However, failure to remove contaminated materials and to reduce moisture and humidity can present serious long-term health risks. Standing water and wet materials are a breeding ground for microorganisms, such as viruses, bacteria and mold. They can cause disease, trigger allergic reactions and continue to damage materials long after the flood.

Replacing Your Flooring after a Flood
If you are repairing your home or building after a flood or hurricane, to prevent mold growth you should be sure your foundation is dry before you replace the flooring. The American Society for Testing and Materials (ASTM) issued a standard which describes an easy way to check if your concrete slab is dry enough to replace the flooring. The basic approach is to fasten the edges of a clear piece of plastic sheeting to a concrete slab, and wait for approximately 16 hours. If moisture is visible on the plastic sheeting, it is still too wet to replace the flooring. For more details, visit the ASTM's portal for standard, testing, learning and more
