Why Be Concerned About Mold?
Mold's purpose in this world is to decompose dead organic materials. If molds did not exist, the trees in a forest would be buried over time by their own leaves. The problem with mold growth, other than physically destroying construction materials in your home (such as lumber, flooring or drywall), is that when mold growth occurs indoors, mold spores can become concentrated, and may cause adverse health impacts. A variety of adverse health impacts to humans (such as allergic reactions, asthma, and other respiratory ailments) have been associated with exposure to mold growth.
How Does Mold Grow Indoors?
Due to their lack of efficient root structures, mold spores can only germinate and thrive when abundant moisture is present. Minor levels of mold growth that commonly occur indoors, in locations such as a shower, generally can be managed through routine house keeping and/or adequate ventilation.
Significant/unhealthful mold growth indoors typically occurs when construction materials are exposed to some form of a water leak. Leaks often are related to plumbing fixtures that have failed/leaked/backed up, or where a home's exterior roofs, windows or walls are not water tight. Often, these types of leaks are not readily observable.
