Common questions about costs and estimates for this service.
Basement waterproofing is expensive due to the range of materials and tools required for both interior and exterior methods. Professional fees, including inspection, labor, and specialized services like mold remediation, contribute to the overall high costs.
The most effective method for waterproofing a newly constructed basement wall is to seal both sides of the concrete on the exterior and interior with RadonSeal. Afterward, allow the sealer to initially cure and the concrete to dry before applying the exterior waterproofing coating (2-4 days).
The cost of waterproofing a basement varies nationally, but can range between $2,000 and $7,000 on average. However, most homeowners pay around $5,000 to fully waterproof their basements, crawl spaces, and foundation.
While costs vary based on severity and methods, an average cost for fully waterproofing a 1,000 to 1,200 sq. ft. basement can fall within the premium tier, ranging from $7,000 to $16,500. Some sources indicate the average for a 1,000-square-foot basement around $13,640, and for a 1,200 sq. ft. basement, roughly $15,000.
Sometimes paying in cash can help lower the overall cost of a basement waterproofing project. One homeowner reported getting a quoted price of $16,500 down to $13,500 by potentially offering an all-cash payment.
