What foundation repair costs in Kansas City, and why the range is wide
Foundation work is priced by the unit: the pier, the strap, the anchor, the crack. The number of units comes from measuring your house. Here are the planning ranges we see across the metro.
Most people searching for this want a single number. There isn't one, because a hairline crack injection and a ten-pier corner are both "foundation repair". What there is, is a pattern: a few kinds of repair, each priced per unit, multiplied by what your house needs. These are planning ranges for the Kansas City metro, not quotes.
| Repair | Unit | Planning range |
|---|---|---|
| Crack injection (poured wall) | Per crack | $450 – $1,100 |
| Carbon fiber wall strap | Per strap | $600 – $1,100 |
| Wall anchor | Per anchor | $700 – $1,300 |
| Steel I-beam wall brace | Per beam | $800 – $1,400 |
| Steel push pier | Per pier | $1,400 – $2,600 |
| Helical pier | Per pier | $1,600 – $3,000 |
| Crawl space support jack | Per jack | $350 – $800 |
| Slab lifting with foam | Per slab | $400 – $2,000 |
| Excavate and rebuild a failed wall | Per wall | $18,000 – $35,000+ |
Typical whole jobs
- One leaking crack in a poured wall: about $450 to $900.
- A bowing 30-foot block wall with straps or anchors: about $5,000 to $11,000, plus drainage if the wall takes water.
- A settling corner on four to six push piers: about $6,500 to $15,000.
- A full side of a house on piers: often $15,000 to $30,000.
What moves the price
Depth to load-bearing soil. Piers are driven until they reach the pressure the load requires; the deeper that is, the more steel. Access. A corner under a deck, a driveway along the wall, or a finished basement adds labor. The wall type. Block, poured and stone walls take different methods. Permits and engineering. Structural work often needs a city permit, and some jobs or buyers call for an engineer's letter. Drainage. A repair that leaves the water problem in place is cheaper today and costlier later, so drainage lines show up on most of our scopes.
Getting a fair number
Ask for measurements. A scope with floor elevations, crack widths and wall deflection written down is one you can compare. Ask how many piers and why that spacing. Ask what happens to the water. And be wary of a price that only exists if you sign today.

Quick questions
Why do quotes for the same house vary so much?
Different methods and different pier counts. One contractor may propose straps, another anchors; one may space piers every six feet, another every eight. Ask each to show their measurements and explain the plan.
Is the cheapest option ever the right one?
Sometimes. A stable crack that only needs watching costs nothing. A downspout extension can solve a wet corner. We start with the least that will work.
Does foundation repair add value to a home?
It protects value. A documented, permitted repair is much easier to sell than an unexplained crack.
