The price of basement waterproofing can vary significantly based on several factors, including the age of your home, the type of foundation, the level of water intrusion, and the scope of repairs needed. Basic fixes—like patching a small foundation crack or installing a dehumidifier—can cost a few hundred dollars. More complex systems involving sump pumps, drain tile, and exterior membranes typically range from $3,000 to $15,000 or more.
