Basement Waterproofing Cost Calculator

Compare planning costs for coatings, interior drainage systems, and exterior excavation and membrane work.

Describe the basement

Measurements determine perimeter and wall area.

Additional work

Choosing a waterproofing approach

Interior coatings can manage limited vapor and dampness but do not stop hydrostatic pressure. Interior drainage collects water and directs it to a sump. Exterior excavation addresses water before it crosses the wall but requires access and restoration.

System cost = measured basis × method rate × severity factor

Start with diagnosis

Check grading, gutters, downspouts, plumbing leaks, wall cracks, floor joints, and groundwater conditions. The right solution depends on the water source.

Frequently asked questions

Is waterproof paint enough for a leaking wall?

Usually not when water pressure or active leaks are present. Correct drainage and defects first.

Does the estimate include mold remediation?

No. Mold assessment and remediation are separate specialized services.
