Typical installed prices for every fix we do, from Wisconsin and national cost guides. They are not quotes. The inspection (if qualified) and a written quote give you the real number.
Installed prices for Waukesha County and Milwaukee-area homes, labor and materials included. Each service links to how the work is done.
| Project | Typical installed price | What it covers and what moves it |
|---|---|---|
| Interior drain tile + sump pump | $40–$120 / linear ft | In Wisconsin, one wall typically runs $2,500–$4,500 and a full basement perimeter (about 120–160 ft) $8,000–$12,000. The tile carries water to a sump crock and pump. |
| New sump pump and crock | $800–$2,500 | Replacing a pump in an existing crock: $350–$1,000. Adding a battery backup pump: about $500–$1,500. |
| Exterior waterproofing | $8,000–$20,000 / job | Excavation to the footing, membrane, drainage board, new weeping tile and backfill. The digging is most of the cost, about $50–$200 per cubic yard of soil. |
| Interior waterproofing (wall sealing + vapor barrier) | $1,500–$4,000 | For damp walls and light seepage. Add a sump pump and crock if the basement doesn't have one. |
| Foundation crack repair | $300–$1,000 / crack | Sealed or injected from inside. A crack that keeps opening means the wall is moving and needs bracing. |
| Carbon fiber wall reinforcement | $4,000–$12,000 | For walls that have only started to bow. Cost guides price a set of about 12 straps in this range; a Wisconsin guide lists $400–$800 per strap. |
| Steel I-beam wall bracing | $4,000–$12,000 / wall | For walls that have moved further. The wall's length, the number of beams and how far it has moved set the price. |
| Egress window | $2,500–$5,500 / window | Below grade, with the opening cut into the foundation, the window, the well and drainage. |
| Structural engineer's report | $300–$1,000 | Optional on most jobs. Worth having for a home sale or a wall that has moved a lot. |
Typical ranges as of October 2026 from published cost guides: AskDoss's Wisconsin basement waterproofing guide (March 2026), Fixr (waterproofing, drains, sump pumps, foundations, egress; 2025–2026), This Old House (waterproofing, foundations, egress, sump pumps; 2026) and Today's Homeowner (bowing walls, egress; 2025). Use them for planning: they are not quotes or our price list, and your written quote after the inspection (if qualified) is the number that counts.
Most basements leak along one or two walls. These Wisconsin ranges show how the price grows with the job.
| Scope | Linear feet | Typical cost in Wisconsin |
|---|---|---|
| One wall | 30–40 ft | $2,500–$4,500 |
| Two walls | 60–80 ft | $4,500–$7,000 |
| Three walls | 90–120 ft | $6,500–$9,500 |
| Full perimeter | 120–160 ft | $8,000–$12,000 |

Feet of drain tile, how many walls get dug out and how many straps or beams a wall needs drive most of the price. One wall costs far less than a full perimeter.
Interior systems go in from the basement. Exterior waterproofing means digging to the footing, so it costs more and depends on what is in the way: decks, steps, driveways and landscaping.
A crack that only leaks can be sealed. A wall that has started to bow takes carbon fiber or steel, and a wall that has moved too far to brace costs the most to fix.
Drywall, trim and flooring along the walls being worked on have to come off and go back, and that labor adds to the price.
An existing crock keeps the cost down. A new crock cut into the floor, a battery backup pump and a long discharge line add to it.
Block and poured walls fail differently and get fixed differently. Deeper basements mean more digging outside, and some jobs need a municipal permit.
