Recently, there has been growing concern over mold in the indoor environment. News stories have focused on numerous health concerns reportedly caused by exposure to mold in the home or office. The most common (documented) symptom is an allergic reaction. At this time, there is still much to learn about what other health effects can actually be directly related to mold exposure.
There are no regulatory limits for mold in the home or office environment (federal, state or local). Because of this, air sampling may or may not prove useful. Sample results can vary widely based on a number of variables. Be sure to discuss with your consultant what it is you expect to determine from any sampling activity.
The best advice is as follows: If you suspect you have a mold problem, look for a source of moisture. Microbials can be found any place. They need a source of moisture and a source of food to grow and multiply. Before successful remediation can take place, the source of moisture must be eliminated or the problem can reoccur.
If you have visible mold, clean it up. Remediation tips can be found at www.epa.gov/iaq/molds. Please be advised, some materials may not be able to be cleaned and may need to be discarded.
