Molds and fungi are found everywhere inside and outside, and can grow on almost any substance when moisture is present. Molds when they reproduce make spores, which can be carried by air currents. When these spores land on a moist surface that is suitable for life, they begin to grow. Molds are essential to the natural breakdown of organic materials in the environment. Mold is normally found indoors at levels that do not affect most healthy individuals.
Because common building materials are capable of sustaining mold growth, and mold spores are ever-present, mold growth in an indoor environment is typically related to water or moisture indoors. Mold growth may also be caused by incomplete drying of flooring and building materials. Flooding, leaky roofs, building maintenance problems, or indoor plumbing problems can lead to mold growth inside homes, schools, or office buildings.
For significant mold growth to occur, there must be a source of water (which could be invisible humidity), a source of food, and a medium capable of sustaining growth. Common building materials, such as plywood, drywall, carpets, and carpet padding are food for molds. In carpet, invisible dust and cellulose are the food sources. After a single incident of water damage occurs in a building without being dried completely, molds grow inside walls and then become dormant until a subsequent incident of high humidity; this illustrates how mold can appear to be a sudden problem, long after a previous flood or water incident that did not produce such a problem. The right conditions reactivate mold.
Both our indoor and outdoor environments have mold spores present. There is no such thing as a mold free environment in the Earth’s biosphere. When these mold levels become abnormally high, as determined by indoor air quality testing or mold inspection, remediation is recommended. It should only be carried out by a professional remediation company, like MERRITT Professional Carpet Cleaning and Restoration, Inc.
