Molds (moulds) are commonly found in areas exposed to water damage such as flooded homes, buildings constructed during wet weather, or prior marijuana grow operations. Most homes and outdoor environments will normally contain small amounts of mold. Molds reproduce by generating tiny airborne spores floating through the air both indoor and out. When mold spores land on damp indoor areas, they may begin growing. Molds commonly grow on surfaces such as drywall, wood, paper, carpet, and foods, often becoming unmanageable when excessive moisture or water accumulates. This can be particularly hazardous if the moisture problem remains undiscovered or unaddressed.
