Foundation Repair Cost Calculator (2026)

Most foundation repairs cost $2,225–$8,133 (average $5,175, HomeAdvisor, Jun 2026). The number that moves your price is how many piers the settling part of the house needs: each pier runs $1,000–$3,000. Pick what you see below to get a range with every line sourced.
What are you seeing?

One side of a typical house is 30–60 ft. Assumes a pier every 6–8 ft — your engineer sets the real count.

How this estimate is built

  • Settling slab: piers = settling wall length ÷ 8 ft (low) to ÷ 6 ft (high), each $1,000–$3,000 (HomeAdvisor, Jun 2026). Spacing is a common industry range; an engineer sets the real number.
  • Cracks only: $250–$800 (HomeGuide, Feb 2026). Sunken slab section: mudjacking $500–$1,300 (HomeAdvisor, Jun 2026). Pier and beam: shim and level $1,500–$10,000 (HomeGuide, Dec 2025).
  • Add-ons: engineer report $340–$780 (HomeAdvisor), regrading $1,000–$3,000 (HomeGuide, Dec 2025), permit $75–$150 (HomeGuide, Feb 2026 — Houston lists a $33.56 admin fee).

City averages: Houston $5,003, Dallas $5,223, Austin $6,815 (Angi, Oct 2025). See the Texas cost guide for permits and insurance, and helical pier pricing for per-pier detail.

Frequently asked questions

How accurate is a foundation repair cost calculator?

It gives a planning range, not a quote. The biggest unknown is pier count, which an engineer sets from your house load and soil; this calculator assumes one pier every 6–8 feet of settling wall, a common spacing, and prices each pier at $1,000–$3,000 (HomeAdvisor, Jun 2026).

How many piers does a house need?

It depends on how much of the foundation has moved. One settling side of a typical house is 30–60 feet, which at 6–8 foot spacing is roughly 5–10 piers. Two or three affected sides multiply that.

What is the average cost of foundation repair?

Nationally about $5,175, typically $2,225–$8,133 (HomeAdvisor, Jun 2026). In Texas metros Angi's 2025 data shows $5,003 in Houston, $5,223 in Dallas and $6,815 in Austin.

Should I pay for a structural engineer before getting quotes?

For slab movement, usually yes. A report costs $340–$780 (HomeAdvisor, Jun 2026) and gives you an independent pier plan, so you can compare contractor quotes on the same scope.
