If you’re budgeting a foundation repair in San Antonio, most projects run $1,689-$12,669, 16% below the $5,000 national average.

Easiest place to save: Get a second opinion from a structural engineer before accepting a foundation repair company's diagnosis - there is an obvious upsell incentive to recommend more work.
