How Mold Found in a Crawlspace Effects Your Health

It is important for the health of inhabitants of a home, including pets, to detect and eradicate mold. In most structures, some type of crawlspaces exists where the access to ducts, pipes, electrical, and flooring is located. Mostly these crawlspaces have poor ventilation and they are prone to the buildup of moisture. According to studies, about 60% of homes have crawlspace mold. Wooden wall framing or sub-flooring, dirt floors, and insulation of fiberglass are the common places where mold grows because these materials give a source of food to crawlspace mold colonies. Moisture may easily get into the crawlspaces by coming inside from the outside gutters and the storm window wells, or leaky interior plumbing and air conditioning systems. Mold will be inevitably present wherever there’s moisture.

Often, the first sign that crawlspace mold might be present is the musty or pungent odor, which is often associated with basements and crawlspaces. Fuzziness or discoloration might be visible on the ceiling. This is mold. Due to dirt floors and insulation, it is likely that you won’t be able to detect the crawlspace mold visually because mold grows within layers of the material. Mold tests at home are available but we cannot stress enough, the importance of your health and the possibility of spreading mold when you’re testing an area.

Mold Can Spread Easily from a Crawlspace

Crawlspaces provide access to numerous areas of the rest of the building via cracks in subflooring and ventilation networks. The mold spores which get disturbed may easily travel to other locations and the problem becomes worse.
