How much does foundation repair cost?
Foundation repair averages about $5,000, with most jobs landing between $2,200 and $8,100 — but the real number depends entirely on what’s wrong. Estimate yours below, then read what drives it.
Estimate only — not a structural diagnosis. Get a licensed engineer's inspection before authorizing work.
Cost by repair type
The repair itself is the biggest lever. From least to most expensive:
What pushes the number up
Severity. Early, cosmetic damage is cheap; active, ongoing movement is not. Extent. One crack or two piers is a small job; a whole wall of piers is a big one. Access. Tight crawl spaces, finished basements, and landscaping that has to come out all add labor. Region. Labor and permitting in high-cost states can add 20–30% over the national average. Soil. Expansive clay (think Texas) and deep frost (the upper Midwest) cause recurring movement that may need ongoing attention.
Repair vs. replace
Replacement is rare. The vast majority of foundation problems are fixed with targeted repairs — sealing cracks, lifting a settled slab, or stabilizing with piers — for a fraction of replacement cost. Full replacement is reserved for foundations with severe, widespread structural failure where piecemeal repair no longer makes economic sense.
Will insurance help?
Usually not — the most common causes are excluded. But if a sudden covered peril (a burst pipe, a fallen tree) caused the damage, you may have a claim. Don’t guess: run the cause through the insurance verdict tool first.
Frequently asked questions
What is the average cost of foundation repair?
The national average is around $5,000, with most repairs falling between roughly $2,200 and $8,100. That average hides a huge range: cosmetic crack sealing can be a few hundred dollars, while major structural work runs into the tens of thousands.
What is the most expensive foundation problem to fix?
Full foundation replacement — lifting the house, removing the old foundation, and rebuilding — at $20,000–$100,000. Among repairs short of replacement, extensive piering/underpinning and major bowing-wall rebuilds are the priciest.
How do I know if foundation cracks are serious?
Thin vertical hairline cracks are usually cosmetic. Horizontal cracks, stair-step cracks in block, cracks wider than about ¼ inch, cracks with one side higher than the other, and doors/windows that suddenly stick are warning signs of structural movement — get a licensed structural engineer to evaluate.
Does insurance pay for any of it?
Only if a covered peril caused the damage (e.g. a burst pipe). The most common causes — settling and soil movement — are excluded. Check your situation with the insurance verdict tool before assuming you’re on your own or that you’re covered.
