Having a home with a basement gives you extra room, but it does come with the risk of leaking and water damage. In this case, you'll want to work with a home basement waterproofing company. Working with them benefits you in many ways as a homeowner. Prevent Mold When you have a basement that's not waterproofed, it's susceptible to moisture buildup and water actually getting through the foundation. This is not ideal because it can cause mold to develop.
