Many homeowners notice water pooling around their basement during the rainy weather and ignore it. However, any water pooling around your basement is also soaking into the porous materials that make up the house. Water damage caused by the slow effects of rainwater causes devastating results in your home, and that's why you shouldn't ignore it. A simple drainage issue in the foundation could also lead to serious water damage. It may even cause you to replace crumbling drywall or the entire foundation.
