Waterproofing Contractors in Houston, Texas
Basement waterproofing and foundation moisture control..
Water intrusion through basement walls and floors is one of the most common and damaging residential problems. Waterproofing contractors address this through interior drainage systems (French drains and sump pumps), exterior excavation and membrane application, crack injection, and vapor barriers. The right approach depends on the source — hydrostatic pressure from a high water table requires different solutions than surface water from poor grading or gutter discharge. A thorough assessment before quoting ensures the solution addresses the root cause rather than just the symptoms.

General Waterproofing FAQs
How much does basement waterproofing cost?
Interior basement waterproofing with a French drain and sump pump system typically costs $3,000–$8,000 for a partial perimeter and $6,000–$15,000 for a full perimeter. Exterior waterproofing — excavating around the foundation and applying a waterproof membrane — costs $8,000–$20,000+ because of the excavation involved. Crack injection for individual foundation cracks costs $300–$800 per crack. The right approach depends on the water source: hydrostatic pressure, surface water, or condensation each require different solutions.
What causes basement water problems?
The three main causes of basement water are: (1) surface water from poor grading, downspout discharge too close to the foundation, or inadequate gutters; (2) hydrostatic pressure from a high water table pushing water through the foundation floor and walls; and (3) condensation from warm moist air hitting cool basement walls. Surface water issues are often fixable with grading, gutter extensions, and landscaping changes before investing in an interior drainage system. A waterproofing contractor should diagnose the source before recommending a solution.
