Basement Waterproofing Cost Calculator for Atlanta, GA
Weighing an interior drain, a sump pump or a few sealed cracks for a basement in Atlanta, GA? This city of roughly 529,000 people, set on a ridge south of the Chattahoochee River along the Eastern Continental Divide, has no local cost source, so four answers here turn 2026 national rates into a rough budget. Nothing asks for your name or number.
What You'll Need
Bring four things to mind: a rough size for the basement floor, which walls show water, whether a sump pump is already working, and how many cracks you can see letting water in. From the floor size, the calculator estimates the length of foundation wall, applies the interior perimeter drain's per-foot rate to the part that gets wet, and adds pump and crack-injection ranges on top. Each row below comes from Fixr's 2026 national figures.
| 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) |
The arithmetic uses three rows: the interior drain, the sump pump and the epoxy crack injection. The typical-project row and the paint row sit there for context, as a sense of where whole jobs and surface coatings tend to fall. No Atlanta, GA or Georgia cost source was found, so all of it is national. An older house, block or brick walls, a sloped lot with a daylight wall, tight access, how much of the basement needs work, any structural repair, historic-district review and any plumbing can each move a real price.
Some work stays out of the model entirely. Exterior excavation, wall bracing, piers, retaining walls, engineering and structural repair aren't priced; structural work also raises its own license and permit questions, so put those to the contractor and the local office. A new circuit or outlet for a pump (electrical work) and egress windows are left out as well.
Plumbing never enters the total: a Georgia-licensed plumber prices backwater valves, ejectors, sump tie-ins, sewer lines and other drain connections, and no City of Atlanta or DeKalb program that helps pay for them turned up, as the Georgia rules guide explains. Permits come from the City of Atlanta, DeKalb or the town's own office, which set their own charges, so no permit cost appears here.
Your Next Move
Treat the range as a list of questions rather than a figure to hold anyone to. For a number tied to your own walls, send the request form; one independent contractor receives it, gets in touch if the job suits it and, if you agree to a visit, puts its own scope and price in writing. Before you sign, ask which Georgia license, if any, the work needs, look the contractor up on the Secretary of State's online license search and ask for its business license. The cost guide walks through the details that raise or lower a total.
