Quick Reference to Mold!
Mold needs moisture to grow. Mold does not grow on dry materials. Molds are microscopic fungi, a group of organisms which also includes mushrooms and yeasts. Fungi are highly adapted to grow and reproduce rapidly, producing spores and mycelia in the process.
You encounter Mold every day. Foods spoil because of mold. Leaves decay and pieces of wood lying on the ground rot due to Mold. That fuzzy black growth on wet window sills is mold. Paper or fabrics stored in a damp place get a musty smell that is due to the action of molds.

What makes Molds grow?
Molds will grow if we provide them water, moisture and nutrients. So If we keep the property dry, Molds dos not grow. High moisture levels can be the result of water coming in from the outside, through the floor, walls or roof, or from plumbing leaks, or moisture produced by the people living in the home, through daily activities like bathing, washing clothes or cooking. Water enters the building when there is a weakness or failure in the structure. Moisture accumulates within the home when there is not enough ventilation to expel that moisture or when water damage has occurred and proper mitigation and remediation is not performed.
