Before you start: the calculator guesses the length of your foundation walls from the floor size, takes the share of wall you say needs a drain, and prices those feet at the interior perimeter drain rate. It then adds a sump pump and crack sealing if you pick them. The rates come from the rows below. Exterior digging isn't included, since there's no sourced figure for it, and tight city lots tend to make outside work cost more.
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project, Boston | about $2,109 to $6,243 (average about $4,116) | Angi, Boston (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) |
The calculator uses the drain, sump and crack rows, which are national figures. The Boston project range is there for context.
