Control the water and you control the mold.
Hidden water leaks lie behind walls, appliances or in ceilings. Not even home inspectors or sellers can find some of these if they don’t know where to look.
Water leaks cause structural damage. Wet wood rots. Wet building materials attract termites, assorted other crawlies, and–of course–provide an environmental haven where mold loves to colonize and spread. Most molds will eventually consume the materials on which they grow, so don’t think that mold damage is limited to the occasional sneezing allergy attack.
In fact, mold exposure can lead to a whole assortment of health problems, including neurological, immunological, and pathological conditions. So stop that leak before it starts a flood of mold that will silently destroy your residence.
