Factors Affecting Basement Waterproofing Costs

Larger basements require more materials and labor, leading to higher costs. Most cost calculators adjust estimates based on square footage.

3. Foundation Type

  • Concrete, stone, or cinder block foundations affect how the work is performed and the cost involved.
