Mold is a microscopic organism that can be found indoors: in the basement, in showers, or in any areas around any heating or cooling appliances. It also grows outdoors in shady or damp places or around decomposing vegetation.

Mold in the basement looks like irregularly-shaped stains or specks that are green, brown, white, black, or orange. The color depends on the type of mold growing in your basement and starts growing as fuzzy white fibers and becomes powdery or fluffy over time.
