Foundation cracks are one of the most common — and most misunderstood — home repair issues. Depending on crack type, width, and repair method, expect to pay $350 to $1,500 per crack.
Cost by Repair Method
Best for structural cracks. Restores concrete strength.
Best for leaking cracks. Expands to stop water.
For bowing walls. Permanent stabilization.
Key Cost Factors
- Crack Width: Hairline cracks under 1/16\" are typically cosmetic. Cracks wider than 1/4\" or with horizontal displacement require professional attention.
- Crack Direction: Vertical cracks are usually settling. Horizontal cracks indicate soil pressure and signal structural failure.
- Access: Interior repairs ($350–$800) are significantly cheaper than exterior excavation ($2,000–$7,000).
- Number of Cracks: Most contractors charge per crack, though multiple repairs in one visit may qualify for a discount.
- Water Infiltration: If cracks are actively leaking, polyurethane foam is required to expand and block the flow.
