Foundation Repair Cost Calculator
Updated October 2026 · Data as of 2026-10-02
Foundation repair runs $2,035 to $8,134 installed (about $5,000 typical). Pick the problem you're seeing below — every band is the dataset's installed range, with a structural-engineer diagnosis toggled on by default and confidence flags carried through.
Foundation repair cost calculator
Pick the problem you're seeing. The result is your dataset's installed band — with a structural-engineer diagnosis toggled on by default, since it drives the repair method and any claim.
Estimated installed cost

low · typical · high, installed. per crack (minor, injected). Includes structural-engineer inspection. Per-pier counts are not published by our sources; ask each contractor for a per-pier line.

How the estimate works
Each option maps to a costed product in our dataset, and the calculator renders that product's installed band — per the unit definition shown with the result. The engineer-inspection toggle adds that row's own band on top rather than folding it into the base figure, because diagnosis sets the repair method. Nothing is scaled or invented.
The band you get tracks the cause: a stable crack is injected for $200–$800 per crack, while structural movement is underpinned or piered — the price jump is the fix, not the diagnosis. A structural-engineer inspection runs $200–$400 and documents the cause for the plan and any insurance claim.
What these national bands can't do: price the pier count (not published by our sources), quote your local labor market, or determine insurance coverage. Get a written diagnosis and at least three local written quotes before budgeting.
