Mold is a type of fungus with spores and hair-like bodies of individual mold colonies which are too small for us to see without a microscope. Molds are decomposers of dead organic material, such as wood; plants; and leaves. When there is a large amount of mold growing on a surface, it will appear to have a black or green color. The color of mold can be influenced by the age of the colony and nutrient source the mold feeds on. When mold grows behind vinyl wallpaper, you will notice pink or purple splotches.

What Causes Mold to Grow?
Any mold growths you may have are going to be caused by result of water incursion. Mold needs water and oxygen, along with a temperature between 40 degrees and 100 degrees Fahrenheit in order to grow. Mold decomposes dead organic (once living) material, which can grow on wood, the paper facing on gypsum board (drywall) and other materials made from wood. Molds can also grow on synthetic materials, such as, adhesives; pastes; and paints, as well as, nonorganic materials such as metal, glass or concrete.
What are the Health Effects of Mold Exposure?
Mold can cause nasal stuffiness, eye irritation, wheezing, or skin irritation. It has even caused death in severe cases. Mold affects people differently, as do allergies. Some people, such as those with serious allergies to molds, may experience more severe reactions. Those exposed to large amounts of molds may also experience severe reactions.
