# Foundation Repair Cost: What Each Method Runs > A numbers-first breakdown of foundation repair pricing by method, including piers, slab lifting, wall anchors, and encapsulation. Canonical: https://foundationrepairlab.com/foundation-repair-cost/ Last updated: 2026-11-06 Foundation repair cost depends on the method, the number of piers, and the depth to bearing soil. Most homeowners should expect a typical repair to fall between $4,000 and $15,000, while major structural work can reach $20,000 to $40,000. This guide breaks down what each method runs so you can compare estimates before signing a contract. ## How Repair Pricing Is Structured Contractors price foundation repair by the unit, not by the hour. A pier job is quoted per pier installed, slab lifting is quoted per square foot, and wall stabilization is quoted per anchor or strap. Before any price is discussed, measure the crack width, record any displacement, and identify the soil bearing depth. An engineer inspection typically runs $400 to $1,500 and produces the scope that determines pier count and placement. Permits vary by city and county and typically take 1 to 3 weeks to process. Inspection lead time is usually 1 to 2 weeks. These timelines affect when work can start, not the material unit price. ## Push Piers Push piers are steel segments driven hydraulically through a foundation bracket until they reach load-bearing strata. The cost is $1,000 to $3,000 per pier. A full pier job commonly runs $6,000 to $30,000 depending on how many piers are required. Arithmetic example: If an engineer specifies 8 push piers at $2,000 each, the pier material and installation subtotal is: 8 × $2,000 = $16,000 Add mobilization, engineering, and permitting, and the final invoice often lands near the middle of the full job range. Push piers are best for heavier structures where the piers can be pushed to refusal on competent soil. ## Helical Piers Helical piers are screwed into the ground with a torque motor and are often used for lighter structures or where installation access is tight. They cost $700 to $2,500 each. Because they are installed by rotation rather than pressure, they can be loaded immediately after installation. Arithmetic example: A job requiring 10 helical piers at $1,500 each equals: 10 × $1,500 = $15,000 That pier-only subtotal excludes excavation, bracket installation, and any interior floor repairs needed after lifting. ## Slab Lifting and Mudjacking Slab lifting raises settled concrete slabs by injecting grout or polyurethane foam beneath them. Mudjacking runs $3 to $8 per square foot. Polyurethane foam injection runs $5 to $15 per square foot. General slab lifting estimates are $3 to $12 per square foot. Arithmetic example: Lifting a 500-square-foot garage slab with mudjacking at $5 per square foot: 500 × $5 = $2,500 The same area with poly foam at $10 per square foot: 500 × $10 = $5,000 Slab lifting addresses settlement but does not stabilize a foundation wall that is moving inward. For more detail, see the breakdown at /mudjacking-cost/. ## Wall Anchors and Carbon Fiber Straps Basement or crawl space walls that bow inward need lateral stabilization. Wall anchors cost $500 to $1,500 each and require excavating soil outside the wall to install an anchor plate. Carbon fiber straps cost $400 to $1,200 each and are epoxied to the interior wall face without excavation. Arithmetic example: A basement wall needing 4 wall anchors at $1,000 each: 4 × $1,000 = $4,000 The same wall with 6 carbon fiber straps at $800 each: 6 × $800 = $4,800 Wall movement beyond 2 inches generally indicates a condition where replacement or major reconstruction should be evaluated rather than continued reinforcement. Related method details are available at /wall-anchor-cost/ and /carbon-fiber-foundation-repair-cost/. ## Crawl Space Encapsulation Encapsulation seals a crawl space with a vapor barrier, insulation, and sometimes a dehumidifier. Material and labor run $3 to $8 per square foot. A full encapsulation job typically costs $4,000 to $15,000 depending on crawl size, access difficulty, and whether drainage or mold remediation is included. Arithmetic example: Encapsulating a 1,200-square-foot crawl space at $5 per square foot: 1,200 × $5 = $6,000 This addresses moisture and indoor air quality. It is not a structural repair for a settling foundation, though it is often packaged with pier work when both issues exist. ## Replacement Versus Repair When a foundation has failed beyond practical repair, replacement runs $40,000 to $150,000. Restoration typically costs 10 to 25 percent of structural replacement value. A common rule of thumb is to consider replacement when repair costs exceed roughly one-third of replacement cost. Arithmetic example: If replacement is estimated at $60,000, one-third is: $60,000 × 0.33 = $19,800 If a repair quote approaches $20,000 on a foundation where replacement is $60,000, replacement deserves serious comparison. ## Crack Width and Measurement Not every crack requires repair. Cosmetic cracks are generally 1/16 inch or narrower. Cracks at 1/8 inch warrant monitoring. Movement limits for foundation walls are commonly set at 2 inches before more aggressive intervention is evaluated. Measure crack width with a crack gauge, record the date, and recheck seasonally before spending on structural repairs. For crack-specific pricing, see /foundation-crack-repair-cost/. ## Internal Cost References Pier-specific pricing varies by soil and access. Push pier detail is at /push-pier-cost/. Helical pier detail is at /helical-pier-cost/. Slab lifting detail is at /slab-lifting-cost/. If your home sits on a crawl space or pier-and-beam system, see /pier-and-beam-foundation-repair-cost/ for system-specific estimates. ## Warranty and Long-Term Cost Pier warranties are frequently lifetime and transferable, though transfer fees run $100 to $500. Mudjacking estimates carry a service life of 5 to 15 years. Poly foam may last longer but costs more upfront. When comparing quotes, ask whether the warranty covers future movement, materials only, or both, and whether transfer fees apply if you sell the home. Measure first, method second, price third. Start with an inspection, confirm crack width and displacement, then compare unit prices for the method that matches the diagnosis.
