Molds can be a serious indoor air quality problem in a home, in a school or in a workplace. Molds procreate by releasing spores into the air. Mold spores that are released into the environment may cause a wide variety of adverse health effects. Additionally, people may experience undesirable health effects in response to nonliving mold-related substances such as mycotoxins, nonliving mold spores and other nonliving cellular structures.

Mold spores are found virtually everywhere and only need the opportune set of conditions to establish a colony and grow. Molds require nutrients and the presence of moisture in order to colonize a surface and grow. Molds are able to colonize many different types of materials and have even been known to grow on mildew-resistant material. Measures to control mold growth should be utilized to prevent mold from establishing itself within a building environment.

If a building exhibits chronic moisture control problems, it is likely to have or to develop a mold problem. Mold can be very elusive and can exist in a building even if it cannot be seen. Mold testing can help find and identify mold within a building; however, testing can be very expensive and is often unnecessary. Mold found in a building should be removed, using proper clean-up techniques, as soon as practical to lessen the health effects on building occupants.
