Molds are tiny microscopic organisms that digest organic matter and reproduce by releasing spores. Molds are a type of fungi and there are over 100,000 species. In nature, mold helps decompose or break-down leaves, wood and other plant debris. Molds become a problem when they go where they are not wanted and digest materials such as our homes. You know you have mold when you smell a musty odor or see small black, darkened, or white specks along a damp bathroom, basement, or other walls.2
Mold enters the home as microscopic airborne spores, from a variety of sources. It is important to know that mold needs moisture to grow. So, controlling mold is a matter of controlling the moisture in the home.

Molds do not generally affect healthy individuals, however those with allergies or asthma may be more sensitive and develop reactions to mold. Sensitive people (and those with prolonged mold exposure) may experience hay-fever type symptoms including: coughing, skin rash, running nose, red eyes, nasal congestion, aggravation of asthma or difficulty breathing. Also, individuals with immune system suppression, lung diseases, are at increased risk for infection from molds.1
Controlling, and preventing moisture will prevent the growth, and spread of Mold.
In most cases, if visible mold growth is present, sampling is unnecessary. Since no EPA or other federal limits have been set for mold or mold spores, sampling cannot be used to check a building's compliance with federal mold standards. Surface sampling may be useful to determine if an area has been adequately cleaned or remediated.
Sampling for mold should be conducted by professionals who have specific experience in designing mold sampling protocols, sampling methods, and interpreting results.
Sample analysis should follow analytical methods recommended by the American Industrial Hygiene Association (AIHA), the American Conference of Governmental Industrial Hygienists (ACGIH), or other professional organizations.3
In all instances it is important to Act fast, as mold damages your home as it grows. Remember that unless the source of the moisture, or cause of water leak is rectified, the mold will regrow, and continue to cause damage and health concerns.
