Shown in the picture is mold growing on a block foundation in a basement. Basements provide some of the most ideal conditions for mold to form. They are cool, damp, and dark. Every basement has the possibility of outside water seeping into the structure for one reason or another leaving increased risk. The best way to prevent mold from growing is to invest in a dehumidifier to keep the moisture levels low so that mold does not grow and to water proof your basement so that water is no longer entering. If mold is found, do not clean with bleach. It does not remove the mold, only bleaches it. The best way to remove mold is to call SERVPRO to inspect the mold and to take samples. The first step to preventing mold, is to first remove it!
