Quick Answer: Foundation repair costs $2,000–$7,500 on average. Crack sealing runs $5–$15 per linear foot. Pier underpinning costs $30–$75/ft (or $1,000–$3,000 per pier). Wall stabilization runs $15–$40/ft. Waterproofing costs $5–$18/ft of perimeter. Labor accounts for 40–60% of total cost, with concrete finisher rates ranging from $21.79/hr (25th percentile) to $30.73/hr (75th percentile) nationally.

Foundation Repair Cost by Type
| Repair Type | Cost/Lin Ft | Typical Project | Total Range |
|---|---|---|---|
| Crack Sealing | $5–$15/ft | 20–50 ft | $500–$1,500 |
| Pier / Underpinning | $30–$75/ft | 30–60 ft | $5,000–$15,000 |
| Wall Stabilization | $15–$40/ft | 20–40 ft | $3,000–$8,000 |
| Waterproofing | $5–$18/ft | 100–160 ft | $3,000–$10,000 |
How Foundation Repair Cost Is Calculated
- Materials: Linear feet × material rate per foot. Crack sealing uses epoxy or polyurethane ($5–$15/ft). Pier work includes steel piers and brackets ($30–$75/ft). Wall stabilization uses carbon fiber straps or wall anchors ($15–$40/ft).
- Labor: Linear feet × hours per foot × hourly rate × 1.5 burden. Pier installation is the most labor-intensive at 0.75 hr/ft. Crack sealing is fastest at 0.25 hr/ft.
- Fixed costs: Mobilization ($200–$500), permits ($0–$300), equipment rental ($100–$800), and excavation ($0–$600) depending on repair type.
- Contractor markup: 20% for overhead, profit, and warranty coverage.
When to Repair vs Replace a Foundation
| Condition | Repair | Replace |
|---|---|---|
| Hairline cracks (<1/8") | Epoxy injection | Not needed |
| Settling (1–2") | 6–10 piers | Not needed |
| Bowing walls (<2") | Carbon fiber / anchors | Not needed |
| Severe settling (>4") | May not be enough | Consider partial replacement |
| Crumbling / spalling | Not recommended | Full replacement ($20K–$100K+) |
Formula Summary
Foundation Repair Cost Formula: Total installed cost includes materials, burdened labor, and fixed costs, multiplied by contractor markup.
Total = (L × M + L × H × R × 1.5 + F) × 1.20
where L = linear feet, M = material cost/ft, H = labor hours/ft, R = hourly trade rate, 1.5 = labor burden, F = fixed costs, 1.20 = markup.
| Repair Type | Material $/ft (mid) | Labor hr/ft | Fixed Costs |
|---|---|---|---|
| Crack Sealing | $10 | 0.25 | $300 |
| Pier / Underpinning | $50 | 0.75 | $2,200 |
| Wall Stabilization | $25 | 0.50 | $1,100 |
| Waterproofing | $10 | 0.35 | $1,900 |
Constants: Labor burden 1.5×. Contractor markup 20%. Fixed costs include mobilization, permits, equipment rental, and excavation (where applicable). Trade: concrete finishers (SOC 47-2051). Rates from BLS OEWS May 2024, 393 metros.
