How Much Does Foundation Repair Cost?
By the HomeLintel Editorial Team · Reviewed 2026-08-24
Foundation repair spans a huge range because 'foundation problems' spans a huge range: sealing a non-structural crack runs $250–$1,000, while stabilizing genuine settlement with steel piers typically costs $5,000–$16,000, and severe whole-perimeter cases exceed $30,000.
The single most important thing to know: the diagnosis matters more than the quote. Most 'foundation cracks' are cosmetic shrinkage; the signals that justify structural repair are doors and windows racking out of square, stair-step cracks in brick or block, sloping floors, and cracks that widen over time.
Cost by repair type
| Item | Typical range | Notes |
|---|---|---|
| Crack injection (epoxy/urethane) | $250 – $1,000 | Non-structural cracks; stops water, restores continuity. |
| Steel push/helical piers | $1,200 – $3,000 per pier | The standard fix for settlement; homes typically need 4–10. |
| Slabjacking / polyleveling | $500 – $2,500 per area | Lifting sunken slabs, walks, garage floors. |
| Bowing-wall reinforcement | $350 – $1,000 per strap/anchor | Carbon fiber straps or wall anchors, typically 4–10 units. |
| Drainage correction | $1,500 – $6,000 | Grading, gutters, French drains — often the root cause fix. |
| Structural engineer report | $400 – $1,000 | Independent diagnosis — the best money in this whole table. |
Buy the diagnosis before the repair
Foundation repair is sold almost entirely by companies that profit from finding problems. Before signing a five-figure piering contract, spend $400–$1,000 on an independent structural engineer with no repair business — their report tells you whether movement is active, what's actually needed, and becomes your spec sheet for comparable bids. On genuine structural work, get three bids against that report; per-pier prices vary widely for identical scope.
Why foundations fail: it's almost always water
Most settlement traces to soil moisture cycles — expansive clays swelling and shrinking (the Texas/Oklahoma belt problem), erosion from poor drainage, or saturation from short gutters and bad grading. That's why drainage correction appears in the cost table: piering a house while water keeps undermining the soil treats the symptom. Any honest repair plan addresses gutters, grade, and drainage alongside structural work.
Does foundation repair hurt resale?
Documented, warrantied repair generally beats an unrepaired problem at sale. Transferable lifetime pier warranties from established companies are close to standard — insist on transferability in writing. Disclose the repair with the engineer's report and warranty; buyers fear the unknown far more than the fixed.
Frequently asked questions
How much does foundation repair cost on average?
Structural settlement repair typically runs $5,000–$16,000 (piers at $1,200–$3,000 each, most homes needing 4–10). Non-structural crack sealing is only $250–$1,000 — which is why an independent diagnosis comes first.
When should I worry about foundation cracks?
Worry signals: cracks wider than about 1/4 inch, horizontal cracks in basement walls, stair-step cracking in brick or block, doors/windows newly sticking or racking, and any crack that visibly grows. Hairline vertical cracks in poured concrete are usually shrinkage.
Is foundation repair covered by insurance?
Usually not for soil movement or settlement — standard policies exclude earth movement. Coverage sometimes applies when a covered peril (like a plumbing leak) caused the damage. Read the exclusions before assuming either way.
How long does foundation repair take?
Typical pier installations finish in 2–5 days. Crack injection is hours. Whole-perimeter underpinning or combined drainage-plus-structural projects can run 1–3 weeks.
Can I sell a house with foundation problems?
Yes — either repaired with transferable warranty and documentation (usually the better economics), or as-is at a discount that typically exceeds the repair cost. Concealing known problems invites post-sale liability in most states.
