Molds are one-type of fungi or single-cell organisms. Other similar microorganisms include mushrooms, yeast, and mildew. Mold is present everywhere—indoors and outdoors. It grows from spores which are distributed by the wind and other means. Usually the spores are inactive, but they will germinate when exposed to the right amount of moisture and warmth, and a suitable food source is present. They serve an important, positive role in nature, by helping to break down organic matter. But molds can also be harmful, both to the health of individuals and to the condition of building components. Molds can be allergenic, infectious or toxic. They can also cause damage to walls, floors, and other structural elements as well as any organic materials that will support their growth.
Consideration. The growth of mold indoors where it can affect air quality presents the greatest concern. Mold is most likely to grow when building materials are affected by roof damage, plumbing leaks, basement water penetration or any other condition that contributes to high moisture levels. Poor maintenance and insufficient air exchanges increase the potential for major mold problems. Homes should be monitored for any signs of mold or conditions conducive to mold growth. All sources or cause of excess moisture should be eliminated immediately. When considering the purchase of a home, a professional home inspection is the first step in assessing conditions. This should be followed an evaluation by a qualified technician for an assessment and testing for harmful molds when conditions dictate or personal concerns exist.
