Foundation repair · cost & coverage report
What does foundation repair actually cost — and will insurance pay for it?
We show the math and cite the policy language. Set your repair below for a live estimate, then check the cause against the coverage verdict no one else answers cleanly.
Estimate only — not a structural diagnosis. Get a licensed engineer's inspection before authorizing work.
Will your insurance cover it?
The cause of the damage decides everything. Pick what happened and see where it lands.
General educational information based on the standard HO-3 policy — not a coverage determination. Only your policy and insurer decide an actual claim.

How much does foundation repair cost?
Most foundation repairs run about $2,200–$8,100, with a national average near $5,000. Minor crack sealing can be a few hundred dollars; major underpinning with piers or a bowing-wall rebuild runs into the tens of thousands, and full replacement is $20,000–$100,000. Use the calculator to narrow it to your repair type.
Does homeowners insurance cover foundation repair?
Usually not. Standard HO-3 policies exclude the most common causes — settling, earth movement, and expansive-soil damage. They DO cover foundation damage from a sudden covered peril such as a burst pipe, fire, or a fallen tree. Our insurance verdict tool walks you through it by cause.
Is it cheaper to repair or replace a foundation?
Repair is almost always far cheaper than replacement. Targeted fixes (crack injection, a few piers, slabjacking) address the problem without rebuilding. Full replacement is a last resort reserved for severe, widespread failure.
Are your estimates accurate?
They are rough planning ranges built from public cost data, not a diagnosis. Foundation work is structural engineering: get a licensed engineer or contractor to inspect, then use our number to sanity-check their quote.
