Before you start, here's how the number is built. Your basement's size sets an approximate perimeter, and your answer about which walls need help decides how many feet of interior drain to price. Those feet are multiplied by the "Interior perimeter drain, per linear foot" row ($40 to $120, Fixr national, 2026). Then the "Sump pump installation" row ($600 to $2,500) and the "Epoxy crack injection, per crack" row ($250 to $1,000) are added if your answers call for them.
Only three things are priced here: interior drainage, a sump pump and crack injection. Digging outside the foundation, bracing a wall or removing finished walls to reach the problem all need a separate quote from the contractor. For a wider view, the "Typical basement waterproofing project, Columbus" row runs about $3,180 to $11,639, with an average of about $7,368 (Angi, Columbus, 2026).
Turn the Result Into a Plan
A range is most useful when you carry it into the conversation with a contractor. Keep the number handy, and when estimates arrive, check that each one lists the drain length in feet, the pump model and where the discharge line ends, so you can compare them line by line.
The cost guide explains why quotes differ, the wet basement checker helps sort out what you're seeing, and the Ohio rules page covers licenses and canceling a home-signed sale.
When you want a real number, send a request. It goes to one independent local contractor, who visits and writes up the price. Contractors may pay this site for advertising, so asking costs you nothing.
