Foundation repair · cost estimator
Foundation repair cost calculator
Pick your repair type and severity for an independent, itemized cost range — tuned to your state. Built from public cost data so you can sanity-check any contractor quote.
Estimate only — not a structural diagnosis. Get a licensed engineer's inspection before authorizing work.
What drives foundation repair cost
Four things move the number more than anything else: the type of repair, how far the damage has progressed, how much of it there is (linear feet of crack, number of piers), and where you live. The calculator turns those into a range instead of a single misleading figure, because real foundation quotes always come as ranges until an engineer has looked.
Typical price by repair type

Before you spend a dollar
Foundation repair is structural engineering, not a home-improvement guess. Get a licensed structural engineer to diagnose the cause — settlement, heave, hydrostatic pressure, or a plumbing leak all look similar but need different fixes. Then collect two or three written quotes and use the estimate above to compare them on equal footing. If a leak or another sudden event caused the damage, check coverage with our insurance verdict tool before you pay out of pocket.
Frequently asked questions
How is the estimate calculated?
We start from national installed price ranges for your chosen repair type, then scale by severity, by quantity (number of cracks or piers), and by a rough regional cost index for your state. An optional structural engineer’s report is added on top. The result is a low–high range, never a single false-precise number.
What does foundation piering cost per pier?
Push piers and helical piers typically run about $1,300–$3,000 per pier installed. Most homes with settlement need several, so a piering job commonly lands in the $5,000–$25,000 range depending on count, depth, and access.
How much is foundation crack repair?
A single crack usually costs $250–$800 to seal or inject. Hairline cosmetic cracks are at the low end; structural cracks needing epoxy or polyurethane injection and possibly carbon-fiber reinforcement are higher.
Should I get an engineer’s report?
For anything beyond a cosmetic crack, yes. A licensed structural engineer’s report (about $350–$1,000) tells you what’s actually wrong, specifies the right fix, and stops contractors from overselling — and it’s essential if you ever need to support an insurance claim.
