How Much Does Foundation Repair Cost?
Foundation repair costs $5,000-$30,000 for typical residential projects and $50,000-$500,000+ for commercial buildings. The method — piers, underpinning, mudjacking, or wall anchors — depends on the failure mode.

Common repair methods and costs
Steel push piers: $1,500-$3,000 per pier (residential), more for commercial depths and loads. Helical piers: similar range, better for lighter structures. Mudjacking/slabjacking: $5-$10/SF for sunken slabs. Wall anchors for bowing basement walls: $500-$800 per anchor. Full underpinning for commercial buildings is engineered per-project.
What drives the cost
Extent of settlement, accessibility (interior piers cost more than exterior), depth to competent bearing soil, and whether the repair is preventive or emergency. Commercial buildings cost more due to higher loads, deeper foundations, and the engineering required for the repair design.
Engineering's role
A structural engineer should diagnose the cause before any repair contractor is hired. Is it settlement, expansive soil, poor drainage, or plumbing leaks? The wrong repair for the actual cause wastes money. The engineer designs the repair, specifies pier depths and capacities, and provides the drawings for permit.
The bottom line
Foundation repair runs $5K-$30K residential, far more for commercial. Get an engineer's diagnosis before hiring a repair contractor.
