Effloresence on the walls of this crawlspace in northern MN

The white chalky powder on the bricks of this crawlspace is a prime example of efflorescence, a substance that is left behind when the water evaporates after coming through the concrete, mortar, or soil. Efflorescence is sometimes confused with mold, but it is not alive or harmful, unless you eat it! It is a clear sign that water is slowly seeping into your crawlspace or basement. We can encapsulate the space, reduce the humidity, and improve your home's overall energy use and comfort!
