Foundation repair cost by repair type
Foundation contractors price jobs by the unit: per pier, per anchor, per strap, or per crack. Once you know how many units your house needs, the total is simple math. These are 2026 U.S. installed prices.
| Repair | Unit | Price range | Typical |
|---|---|---|---|
| Steel push pier | per pier | $1,000 – $3,000 | $1,700 |
| Helical pier | per pier | $1,500 – $4,000 | $2,300 |
| Wall anchor | per anchor | $500 – $1,100 | $750 |
| Carbon fiber strap | per strap | $450 – $1,000 | $700 |
| Steel I-beam brace | per brace | $600 – $1,400 | $900 |
| Crack injection | per crack | $350 – $1,000 | $600 |
| Slab lifting, polyurethane foam | per sq ft | $10 – $20 | $10 |
| Slab lifting, mudjacking | per sq ft | $0 – $10 | $10 |
| Structural engineer report | per visit | $500 – $1,500 | $800 |
| Permit | per job | $100 – $600 | $250 |
Prices run 15–30% higher in expensive metros such as New York, Boston, the San Francisco Bay Area, and Seattle, and about 15% lower in rural areas. The calculator adjusts for this.
Example foundation repair projects
Here is what common jobs cost at average U.S. prices. The pier and anchor jobs include an engineer’s report and a permit.
| Project | Range | Typical |
|---|---|---|
| Seal one leaking wall crack | $350 – $1,000 | $600 |
| Inject three cracks | $1,050 – $3,000 | $1,800 |
| Lift a 200 sq ft sunken garage slab (foam) | $1,000 – $3,200 | $1,800 |
| Stabilize one bowed wall with 6 carbon fiber straps | $3,200 – $7,500 | $5,000 |
| Stabilize one bowed wall with 5 wall anchors | $3,100 – $7,600 | $4,800 |
| Pier one settling corner (4 push piers) | $4,600 – $14,100 | $7,850 |
| Pier a settling side of the house (10 push piers) | $10,600 – $32,100 | $18,100 |
| Pier the whole house (24 helical piers) | $36,600 – $98,100 | $56,300 |
Which repair fits which problem
Settling or sinking: piers
When part of the house is sinking, crews drive steel piers down to stable soil or bedrock and lift the foundation back toward level. Push piers use the weight of the house to drive the pier and suit heavier homes. Helical piers screw into the soil like a giant auger. They work under lighter structures, porches, and additions, and can be installed before the load is on them.
Bowing or leaning walls: anchors, straps, or braces
Horizontal cracks and inward bowing in basement walls come from soil pressure. The fix depends on how far the wall has moved:
- Carbon fiber straps for walls bowed less than about 2 inches. They are thin, strong, and need no digging outside.
- Wall anchors for walls bowed up to about 3 inches. A plate on the wall ties to an anchor buried in the yard, and the rod can be tightened over time to pull the wall back.
- Steel I-beam braces when there is no room outside for anchors. They run from the floor to the joists.
- Rebuilding the wall when it has moved more than about 3–4 inches. Expect $15,000–$35,000 or more per wall.
Cracks: injection
Epoxy injection bonds a crack back together structurally. Polyurethane injection stays flexible and is better for stopping leaks. Both run $350 – $1,000 per crack. Injection seals a crack but does not stop the movement that caused it.
Sunken slabs: foam or mudjacking
Garage floors, patios, and sidewalks can be lifted by pumping material underneath. Polyurethane foam costs more but is lighter, cures in minutes, and uses smaller holes. Mudjacking is cheaper and heavier.
What drives foundation repair cost
- Number of units. Piers, anchors, and straps are the biggest line on almost every quote.
- Depth to stable soil. Piers are often priced to a set depth, such as 20–25 feet, with an extra charge per foot beyond it.
- Access. Finished basements, decks, landscaping, and tight side yards add labor. Drywall and flooring removal is often excluded from the quote.
- Soil. Expansive clay, common in Texas, Oklahoma, Colorado, and parts of California, drives many repairs and can need more piers.
- Engineering and permits. Many cities require a stamped engineer’s plan for piering.
- Warranty. Lifetime, transferable warranties cost more but add resale value.
Signs you need foundation repair
- Horizontal or stair-step cracks in basement walls
- Cracks wider than 1/4 inch, or cracks where one side sticks out past the other
- Walls that bow or lean inward
- Doors and windows that stick or will not latch
- Sloping floors, or gaps between floors and baseboards
- Diagonal drywall cracks from the corners of doors and windows
- Chimney pulling away from the house
Hairline vertical cracks in poured concrete walls are usually harmless shrinkage cracks. The crack checker helps you sort the harmless ones from the serious ones.
Get the engineer’s report first. A structural engineer visit costs $500 – $1,500. It is the most effective way to avoid paying for piers you do not need, and it gives every contractor the same scope to bid on.
How to avoid overpaying
- Start with an independent engineer, not a contractor’s free inspection.
- Get three quotes for the same scope, in writing, with the number and spacing of piers or anchors listed.
- Compare price per unit. Divide the total by the number of piers or anchors and compare it with the table above.
- Read the warranty. Check whether it is transferable, what it covers, and whether it includes re-adjustment.
- Ask what is excluded: permits, engineer, landscaping, drywall repair, and plumbing tests after lifting.
- Fix the water. Gutters, downspout extensions, and grading are cheap and prevent many repeat problems.
Use the quote checker to compare any quote against typical prices in seconds.
Frequently asked questions
How much does foundation repair cost on average?
It depends on the problem. Sealing a crack runs $350 – $1,000. Stabilizing a bowed wall is usually $3,000–$10,000. Piering a settling section typically runs $6,000–$20,000, and whole-house piering can pass $40,000.
Does homeowners insurance cover foundation repair?
Usually not. Standard policies exclude settling, soil movement, and wear. Coverage can apply when a sudden covered event, like a burst pipe, damages the foundation. Florida, Tennessee, and some other states offer sinkhole coverage.
How many piers does my house need?
Piers are usually spaced 5 to 8 feet apart along the section that is settling. A 30-foot settling wall typically needs 4 to 6 piers. A structural engineer’s report will give the exact number.
Is foundation repair worth it?
For real structural movement, yes. Unrepaired foundation problems usually get worse, cause door, drywall, and plumbing damage, and can cut 10–15% or more off a home’s sale price. Buyers’ lenders often require the repair before closing.
Should I hire a structural engineer or a foundation contractor first?
An engineer first. Engineers are paid for the diagnosis, not the repair, so they have no reason to oversell. Their report gives you a scope that every contractor has to quote, which makes quotes comparable.
How long does foundation repair take?
Crack injection takes a few hours. Wall straps or anchors take 1–2 days. Most piering jobs take 1–3 days, plus permit and inspection time.
