Yes. If indoor mold is extensive, those in your home can be exposed to very high and persistent airborne mold spores. It is possible to become sensitized to these mold spores and develop allergies or other health concerns, even if one is not normally sensitive to mold.
Left unchecked, mold growth can cause structural damage to your home as well as permanent damage to furnishings and carpet.
According to the Centers for Disease Control*, “It is not necessary, however, to determine what type of mold you may have. All molds should be treated the same with respect to potential health risks and removal.”
