Molds are a natural part of the environment and can be found almost anywhere that moisture and oxygen are present. They belong to the kingdom Fungi and thrive in moist places such as soil, plants and dead or decaying matter. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves, dead trees, and other debris; however, mold growth indoors is unhealthy and should be avoided.

There are many types of mold – all of them need water or moisture to grow. When excessive moisture accumulates in buildings or on building materials, mold growth often occurs, particularly if the moisture problem remains undiscovered or unaddressed. Mold growth can occur on, Wood, Paper, Carpet, Furniture, Paint, Foods, Insulation, and other organic materials. When mold spores land on damp spots or surfaces, they may begin growing indoors and digesting whatever they are growing on to survive. Eventually molds will destroy the things on which they grow.

There is always some mold around. Molds have been on the Earth for millions of years. Mold can get in your home through open doors, windows, vents, and heating and air conditioning systems. Mold in the air outside can be brought indoors on clothing, shoes, bags, and even pets.

Mold will grow where there is moisture, such as around leaks in roofs, windows, or pipes, or where there has been a flood. Mold grows on paper, cardboard, ceiling tiles, and wood. Mold can also grow in dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery.
