When your sump pump fails during a storm, flood water begins to build up rapidly in your house, be it the basement, foundation, attic, or crawlspace.There are several risks associated with excess water settling beneath your house. Water damage can rot wood, shift and erode the soil beneath your foundation, and it even attract insects and other unwanted symptoms like mold.When the foundation is compromised, cracking and shifting of your home structure is a possibility. Such shifts may lead to uneven flooring, cracked walls, mold, dampness, and so on. Sump pumps play an integral role in keeping these water damage risks at bay.
