Before you start: the tool estimates how many feet of foundation wall your basement has from its floor area, multiplies that by the share of wall you say needs a drain, and prices the length at the interior perimeter drain rate. A sump pump and epoxy crack injection are added when you choose them. Those three cost rows come from Fixr's 2026 national figures in the table below. Digging outside the foundation isn't priced, because no sourced figure exists for it.
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project | about $3,000 to $10,000 (average about $5,000) | Fixr national (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |
| Epoxy crack injection, per crack | $250 to $1,000 | Fixr national (2026) |
| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
Only the drain, sump and crack rows feed the math. The project and sealant rows are there for context, and every figure in the table is a national one.
