What is mold?
We have probably all encountered mold at one time or another. It might have been in the shower, or on a stale piece of bread or wet drywall. Mold is a microscopic life form found in all parts of the world. It is part of the natural decay process of organic materials. There are many different species of mold, and while they are diverse, they share some common characteristics:
Molds require an organic food source. The most common food source indoors is cellulose, which is found in building materials such as wood and drywall.
Molds require oxygen, so they do not grow under water.
Molds require moisture. To prevent mold, buildings must be kept dry.
Molds are spread by tiny particles called “spores.”
Why is it a problem?
The colored, fuzzy growth on the surface of a wall, floor, ceiling or other indoor surface is obviously very objectionable.
Active mold colonies usually emit a very unpleasant, musty odor.
Because the job of mold is to digest, decay and recycle dead organic matter, it will eventually destroy whatever surface it grows on.
Exposure to mold spores can cause mild to severe allergic reactions, depending on individual sensitivity.
