It depends on the failure. Bowing-wall stabilization runs $500 to $1,000 per strap or beam. Push pier underpinning runs $1,200 to $2,500 per pier, with most projects landing $8,000 to $25,000. Slab leveling runs $500 to $1,800. Free on-site inspections produce a fixed quote.
More detail
Foundation repair is priced by the type and extent of the failure, not by square footage, so the only honest number comes after an on-site inspection. Settlement repaired with push piers is the most variable: piers cost $1,200 to $2,500 each, and projects need anywhere from 3 piers for a single dropped corner to 14 or more for a full settling wall, which is why typical Greater Cincinnati pier projects land between $8,000 and $25,000. Depth to competent strata is the swing factor; a 15-foot pier costs less than a 35-foot pier on a Price Hill or Covington hillside. Bowing-wall work is priced per element: carbon-fiber straps and steel I-beams run $500 to $1,000 each installed, wall anchors $600 to $1,000 each, spaced per the engineer's plan. Slab and concrete leveling with polyurethane foam runs $500 to $1,800 for a typical garage floor, walkway, or set of steps. Structural crack repair runs $500 to $1,500 per crack. Two pricing red flags to avoid: a per-pier or per-beam price quoted over the phone with no on-site assessment and no engineer involved, and any contractor unwilling to put a fixed scope and price in writing before work begins. The Cincinnati standard is a written, fixed-price proposal tied to a licensed engineer's recommendation, signed before any digging or installation starts. We also encourage a second opinion any time a quote varies more than 15 to 20 percent from another credentialed contractor on the same scope.
