How much does foundation repair cost?
Most homeowners spend $2,500 to $12,000 on foundation repair. Sealing a few hairline cracks can cost under $1,000, while piering a settling home or rebuilding a failed basement wall can run $15,000 to $30,000 or more. The biggest factor isn’t the size of your house. It’s what the foundation is actually doing: cracking, bowing inward, or sinking.
Here’s what the calculator returns for common jobs at average U.S. pricing, including a structural engineer’s report and permit where the work is structural:
| Typical job | Estimated cost |
|---|---|
| Seal 2 hairline wall cracks | $900 |
| Level sagging floors with 6 crawl space jacks | $4,350 |
| Anchor a 30 ft basement wall bowing 1–2 inches | $6,150 |
| Pier 40 ft of a settling foundation (7 push piers) | $12,550 |
| Excavate and rebuild a 30 ft basement wall | $19,050 |
Cost by repair type
| Repair | Typical price | Used for |
|---|---|---|
| Crack injection | $400–$800 per crack | Hairline cracks that leak |
| Structural crack repair | $700–$1,200 per crack | Wide or displaced cracks |
| Carbon fiber wall straps | $600–$1,000 each | Walls bowing less than 2 inches |
| Wall anchors | $700–$1,200 each | Bowing walls with room to dig an anchor in the yard |
| Steel I-beam braces | $800–$1,300 each | Larger bows, tight lots |
| Wall excavation & rebuild | $500–$800 per linear ft | Walls bowed 3+ inches or sheared |
| Steel push piers | $1,300–$2,000 each | Settling homes, heavier loads |
| Helical piers | $1,600–$2,500 each | Lighter structures, porches, additions |
| Mudjacking | $4–$8 per sq ft | Lifting sunken slabs cheaply |
| Polyurethane foam lifting | $7–$14 per sq ft | Lifting slabs with less weight and mess |
| Crawl space support jacks | $400–$800 each | Sagging or bouncy floors |
| Structural engineer report | $500–$1,000 | Independent diagnosis |
Cosmetic or structural? Reading the warning signs
Not every crack is a foundation problem. Concrete shrinks as it cures, and thin vertical cracks in poured walls are common and usually harmless. These signs point to real movement that deserves a closer look:
- Cracks wider than 1/4 inch, or cracks where one side sits higher or further out than the other.
- Horizontal cracks or stair-step cracks in block walls, which usually mean soil pressure pushing the wall in.
- Walls that bow, lean or bulge when you sight down them.
- Doors and windows that stick or won’t latch, especially new diagonal cracks at their corners.
- Sloping or bouncy floors, gaps between walls and ceilings, or chimneys pulling away from the house.
A simple test: draw a pencil line at each end of a crack and date it. If it grows over a few months, the foundation is still moving.
What pushes the price up or down
- The type of movement. Sealing cracks is cheap. Stabilizing a wall costs more, and lifting a settling home with piers costs the most because each pier is driven to stable soil or bedrock.
- How much of the foundation is affected. Anchors, braces and piers are priced per unit, so a 20-foot problem costs far less than a whole-house one.
- How long you wait. A wall bowing one inch can often be stopped with straps. Let it reach three inches and you may be paying to rebuild it.
- Access. Finished basements, decks, driveways and landscaping along the foundation add labor to remove and restore.
- Soil and region. Expansive clay soils and high-cost labor markets both raise prices.
Costs people forget to budget for
- Engineer’s report: $500–$1,000. Worth it before any structural repair. Contractor “free inspections” are sales visits.
- Permits: Typically a few hundred dollars for structural work, depending on your town.
- Landscaping and hardscape: Replacing plants, sod or concrete disturbed by excavation or anchors.
- Interior touch-ups: Lifting a house can crack drywall and knock doors out of square. Budget $1,000–$2,000.
- Drainage fixes: Gutters, downspouts and grading that caused the problem in the first place. See our waterproofing cost calculator.
How to get a fair quote
- Start with an independent engineer. A report from someone who isn’t selling the repair tells you what’s needed, and contractors can bid on the same scope.
- Get at least three written bids. Compare the method and the number of piers or anchors, not just the total.
- Ask for an itemized quote. Each pier, anchor, permit and restoration item should be listed separately.
- Get the warranty in writing. Many pier and anchor systems carry lifetime, transferable warranties. That matters when you sell.
- Avoid big deposits. Be wary of high-pressure “sign today” pricing or demands for most of the money up front.
Paying for foundation repair
Homeowners insurance rarely covers foundation repair, because settling, soil movement and gradual water damage are standard exclusions. It may help if a covered event, such as a burst pipe, caused the damage. Most people pay with savings, a home equity loan or line of credit, a personal loan, or financing offered by the repair company. Government-backed options such as HUD Title I property improvement loans and USDA home repair programs can help eligible homeowners. Compare interest rates and terms before you sign, and don’t let financing pressure rush the decision.

Frequently asked questions
How much does it cost to fix a crack in a foundation?
Sealing a hairline crack with epoxy or polyurethane injection typically costs $400–$800. Wide or displaced cracks that need reinforcement run about $700–$1,200 each. If the crack is a symptom of bowing or settling, the underlying repair will cost more.
How much do foundation piers cost?
Steel push piers usually run $1,300–$2,000 each and helical piers $1,600–$2,500 each. Piers are spaced about every 6 feet along the settling section, so most jobs need 6 to 12 piers, or roughly $8,000–$25,000.
Is a bowing basement wall an emergency?
A wall bowing less than an inch isn’t usually an emergency, but it should be stabilized before it gets worse. Walls bowing two inches or more, or walls with horizontal cracks that are widening, should be looked at by a structural engineer promptly.
Does homeowners insurance cover foundation repair?
Usually not. Standard policies exclude settling, soil movement and gradual water damage. Coverage may apply if a covered event, such as a burst pipe or fire, directly caused the damage.
Should I buy a house with foundation problems?
It can be a good deal if you know the repair cost up front. Get a structural engineer’s report and at least one repair quote during your inspection period, then negotiate the price or ask the seller to complete the repair with a transferable warranty.
