Basement water usually comes from hydrostatic pressure pushing moisture through foundation cracks, a high water table, or poor drainage around the house. Clogged gutters and downspouts that dump water too close to the foundation are common culprits. Sometimes it's just heavy rain overwhelming the soil, but other times it's a leaking pipe or a failed sump pump that's causing the problem. Figuring out the source is key to stopping the seepage.
