Mold overgrowth is especially dangerous to young children, the elderly, people with asthma or mold allergies and people with other chronic illnesses (especially if they involve respiratory issues). It can also create an unhealthy situation for your beloved pets. If you have a black mold issue in your home or business, the first thing we must do is seal away the area and wear protective gear. We have to reduce the moisture or humidity in that area to slow and stop the mold growth as we combat it.
