Foundation repair cost
Foundation work is priced by what is actually wrong, and the published range spans a factor of thirty because a hairline crack and a bowing basement wall are the same two words. The figures below are the national ranges one guide publishes; the breakdown matters far more than the headline number here.

What moves the price
- What is actually wrong
- A cosmetic crack is a few hundred dollars; a wall moving under soil pressure is five figures. Nothing else on this page moves the number as much, and only an engineer's report settles which one you have.
- Water
- Most foundation problems are drainage problems. Fixing the foundation without fixing what is soaking the soil around it buys a repeat visit.
- Access
- Work reached from outside means excavation around the house; work reached from inside means moving whatever is in the basement.
- Soil
- Expansive clay moves with moisture and is the usual culprit behind repeated cracking; the soil is why the repair is needed and why it can recur.
