Because moisture is an essential part of mold growth, it is vital to clean up the mold AND get rid of excess water or moisture. If the excess water or moisture problem is not fixed, mold will most probably grow again, even if the area was completely cleaned. Clean hard surfaces with water and detergent and dry quickly and completely. Absorbent materials such as ceiling tiles may have to be discarded.
Note that mold can cause health effects such as allergic reactions; remediators should avoid exposing themselves and others to mold. Wear waterproof gloves during clean up; do not touch mold or moldy items with bare hands. Respiratory protection should be used in most remediation situations to prevent inhalation exposure to mold.
According to industry guidelines, any visible mold growth over 10 sf (approximately 3’ x 3’), should be remediated by a qualified contractor trained and certified in mold remediation and following the EPA and/or IICRC S-520 Standards and Guidelines.
