Foundation Waterproofing Costs: What to Expect

The cost of foundation waterproofing is influenced by several factors. The size of the foundation is a major consideration, as larger homes typically require more materials and labor. The extent of existing damage, such as cracks or deterioration, can also impact pricing due to the additional preparation work needed. The type of waterproofing system selected; whether it’s membranes, coatings, or drainage solutions, will further affect the overall cost. Accessibility plays a role as well, especially if the foundation is below grade or obstructed, which can add complexity to the job.
