Basement waterproofing contractors stop leaks with drainage systems, sump pumps and sealing. Waterproofing contractors install interior drain tile and sump pumps, exterior membranes, crack injection, window well drainage, vapor barriers and dehumidifiers to keep basements dry.
Typical cost: $3,000–$12,000 for interior drainage systems. See the full cost guide

Questions to ask this contractor
