Black Lumber Mold – how did it get here?

“Lumber that is solid and piled in moist weather conditions will have a tendency to mildew, leaving a dark

 almost black stain on the lumber. As lumber is exposed to the atmosphere, the moisture content goes down and it will equalize in the surrounding atmosphere at about 11%. This is well below the level needed to support fungi or mildew.” LACN

“Molds are typically characterized as fungi that discolor the wood surface through the production of pigmented spores that can be yellow, green, orange, black and an array of other colors. WWPA, Pg 4. Mold spores are present on surfaces in all homes, so cleaning will not prevent re-growth of mold (Taylor, 2004).

Every year billion of board feet of lumber are installed in our buildings, some with black lumber mold. Fungi only need oxygen, temperature, food, and water to grow. Controlling moisture in the environment is an essential task in preventing mold growth. In the event mold growth is visible on the surface “there are a number of products on the market, from commercial mildewcides to common bleach, which are promoted for removing mold from wood. However, the U.S. Environmental Protection Agency suggests using mild detergent and water for most mold clean up. For cleaning wood surfaces, the EPA recommends wet vacuuming the area, wiping or scrubbing the mold with detergent and water and, after
