Foundation Repair Cost Calculator

Estimate the low / typical / high cost of a foundation repair from repair type, extent, and location.

Foundation repair is hyper-local and soil-driven — ±50% variance is common. This is a planning estimate, not a quote. A licensed local foundation contractor inspection is always required.

Decision guidance

  • Foundation repair is method-driven, not owner-chosen — the soil failure dictates whether you need piers, foam lifting, or wall stabilization.
  • Piering is the most substantial line item ($10k–$40k); crack injection is the cheapest ($250–$800 per crack).
  • Mudjacking is a stopgap for minor settling, not a permanent fix; polyjacking (foam) lasts longer but costs more.
  • Get at least three quotes from a licensed local contractor before committing — the estimate here is a national-average planning range.
  • Sinkhole zones (FL/Gulf) require geotechnical engineering (GPR) before any slabjacking.

Worked reference: for a moderate-settling slab, Southwest, piering runs roughly five figures — always confirm on site, not in a browser.

Data sources

Cost data from Fixr, Angi / HomeAdvisor, BobVila, HomeGuide, Olshan, BuildMat, Modernize, TwoBros (2025–26). Regional multipliers per BuildMat regional guide. National averages approximate; costs climbed ~10% since 2019 and ~18% since 2023 — keep data current.

Notes: Piering is method-driven, not owner-chosen — the method is dictated by the soil failure, not preference. Mudjacking is a stopgap, not a permanent fix. Sinkhole zones (FL/Gulf) require geotechnical engineering (GPR) before slabjacking. Estimate based on national averages; actual price requires a licensed local foundation contractor inspection. Costs vary up to ±50% by site. All math runs in your browser.
