Controlling Mold Growth: It's All About Moisture ControlBecause mold can grow on many different types of materials, it is essential to maintain effective moisture control within a building. The fact that molds need moisture to colonize a surface means that preventing excess moisture in a building usually will prevent mold from growing. Once mold has established itself as a colony, it often can survive in much less moisture than was required to establish the colony. Additionally, the reintroduction of even a slight amount of moisture into an environment where an inactive mold colony exists can trigger new growth of the colony.
Moisture can enter a home through many different means, such as pipe leaks, roof leaks, high ground water and condensation. In addition, many daily activities can produce moisture. Some of these include cooking, showering and drying clothes. In fact, people themselves produce about three pints of water vapor per day while breathing.
Mold growth in a building can be prevented by practicing effective moisture control procedures. Examples of moisture control methods include:
