Where does mold come from?

A mold situation begins with those small, dark, little dots that, with ample moisture and nutrients, gradually spreads and grows across a wall or on a surface. You may open a closet door and see a dark circular pattern growing on the back wall and can only wonder how it got there?

Mold has to come from somewhere and the reality is, it’s no mystery. Mold found indoors comes from the outdoors. There are many types of mold found in the environment—tens of thousands of species in a wide variety of colors, in fact—and many ways it can get in your home. Mold spores can drift indoors through a screened window or open door, or it can be carried in on shoes, a golf bag, a backpack, or a coat that gets hung in a closet, and then spread through the ventilation system. Mold spores can also enter your home through leaky roofs, foundations, door frames or window casements. Once the spores that are carried in or drift in are exposed to dampness, moisture or water, mold usually begins to grow there. The spores that come in through a leak somewhere in the structure of your house are already primed to grow.
