The repair method determines cost more than any other factor: epoxy injection, carbon fiber straps, wall anchors, and helical piers each address a different problem at a different price point.
Foundation repair cost by method
Each repair method addresses a specific type of foundation problem. Getting the wrong method applied to your problem wastes money and may not fix the underlying issue.
| Repair Method | Problem It Solves | Typical Cost Range |
|---|---|---|
| Epoxy crack injection | Structural hairline to 1/2" cracks in poured concrete | $250–$800 per crack |
| Polyurethane injection | Active water-leaking cracks (expands to fill voids) | $200–$500 per crack |
| Carbon fiber straps | Bowing block or poured concrete walls (early stage) | $400–$700 per strap; $4,000–$8,000 typical job |
| Wall anchors | Bowing block walls with room for exterior anchor plate | $500–$800 per anchor; $3,000–$6,000 typical job |
| Helical piers | Settlement (sinking foundation) — stable deep soil required | $1,500–$3,000 per pier; 4–8 piers typical |
| Push piers | Settlement — existing structure load used as resistance | $1,000–$2,500 per pier; 6–12 piers typical |
| Mudjacking / foam lifting | Sunken slab (driveway, garage, interior floor) | $500–$2,000 per section |

Common Questions
Foundation repair questions, answered
Foundation repair costs range from $250 for a single epoxy crack injection to $25,000+ for full underpinning or pier installation. The most common repair — sealing a single non-structural crack — runs $250–$800. Settlement repairs requiring piers typically cost $1,000–$3,000 per pier, with most homes needing 4–12 piers.
Simple crack injection takes 2–4 hours. Wall stabilization with carbon fiber or steel anchors takes one day. Pier installation for settlement typically takes 1–3 days depending on the number of piers required. Most homes can remain occupied during the work.
Standard homeowners insurance typically does not cover foundation repair caused by settling, soil movement, or aging. Coverage may apply if the damage results from a sudden, covered event like a burst pipe or earthquake (with earthquake coverage added).
Review your policy and ask your contractor for documentation that supports any claim you intend to file. A licensed contractor can tell you what repair documentation insurers commonly request.
Verify the contractor's state license, check that they carry general liability and workers' compensation insurance, and ask specifically about their warranty for the repair method they're recommending. Reputable foundation contractors provide written warranties of 10–25 years on structural repairs.
Get at least two estimates. If one estimate recommends a significantly more expensive repair than another, ask each contractor to explain specifically why the less expensive approach won't work for your problem.
