Kansas City foundation repair costs at a glance
Published prices, checked October 19, 2026:
| Repair | Typical KC / published range | Unit | Source |
|---|
| Push pier | $1,250–$2,500 (Olson $1,600–$1,800; Foundation 1 $1,700–$2,200) | per pier | FIA, Heartland, Olson, Foundation 1 |
| Helical pier | $1,800–$3,000 (Olson $1,950–$2,450; Foundation 1 $1,900–$2,450) | per pier | FIA, Olson, Foundation 1 |
| Tieback / deadman anchor | $1,100–$1,500 | per anchor | Olson, Foundation 1 |
| Wall anchor (estimator range) | $500–$1,500 | per anchor | FIA, Foundation 1 |
| Steel wall beam | $500–$800 KC; up to $1,500 national | per beam | Olson, Foundation 1, Slab Local |
| Carbon fiber strap | $300–$800 | per strap | FIA, FoundationCosts.com |
| Crack injection | $250–$800 per crack; $40–$50 per ft (KC) | per crack / ft | HomeGuide, Olson |
| Mudjacking | $3–$8 | per sq ft | Pricestead |
| Polyjacking | $5–$25 | per sq ft | Pricestead |
| Crawl space support jack | $500–$1,000 | per jack | Pricestead |
| Interior drain tile | $75–$90 | per ft | Olson |
| Sump pump | $1,800–$2,000 ($2,400–$2,600 with battery backup) | each | Olson |
| Structural engineer report | $500–$3,000 | each | HomeGuide |
Typical whole jobs: $4,000–$15,000 (Olson) and $4,500–$16,000 (Foundation 1). Full piering projects with 5–10 piers run about $5,000–$30,000 (FIA). Angi's reported KC average is $5,569 (range $1,953–$9,185), as cited by Heartland FR; we haven't verified this on Angi directly.
How the estimator works
- Piers, cracks, jacks: your count × the per-unit range.
- Bowing walls: enter the wall length. We assume one carbon fiber strap per 4 ft and one anchor per 5 ft (spacing per HomeGuide). For steel beams we assume one per 4 ft; that spacing is our assumption, so you can override it with the count from your quote.
- Slab leveling: square feet × the per-sq-ft range.
- Add-ons: drain tile by the foot, sump pump, optional engineer report.
- Totals are rounded to the nearest $100 and always shown as a range.
Example: 6 push piers + 40 ft drain tile + sump pump
6 × $1,250–$2,500 = $7,500–$15,000; 40 × $75–$90 = $3,000–$3,600; sump $1,800–$2,000 → about $12,300–$20,600.

What moves the price up or down
- Depth to stable soil. One KC contractor says local clay can extend 15–25 ft before limestone (FIA); deeper piers need more steel.
- Access. Decks, patios, driveways and tight side yards add excavation and restoration.
- Method. Stabilizing a wall in place usually costs less than straightening it.
- Specialty work. Chimney, porch and garage piers: $2,200–$2,600 each at Foundation 1.
- Scope bundling. Drainage, crack injection and finish repair can be in or out of a bid.

What the estimate doesn't include
- Permits (HomeGuide lists $75–$150 nationally; check your city)
- Unexpected conditions found on site
- Landscaping, concrete or deck removal and restoration
- Interior drywall, paint or flooring repair
- Minimum job charges (not published, so not modeled)
For significant structural movement, consider an independent structural engineer's evaluation before choosing a repair.
