How Much Does Foundation Repair Cost?
Estimate foundation crack repair costs — epoxy injection, materials, labor and when a structural project is really needed.
Most foundation repair questions start with a crack. This guide explains how crack injection is priced, what turns a simple repair into a structural project, and embeds the calculator so you can estimate with real numbers.
THE SHORT ANSWER
The short answer
Epoxy or polyurethane crack injection typically runs $250–$800 per crack plus labor, so a typical 3-crack repair costs about $1,650–$3,300. Major settlement, bowing walls or underpinning are structural projects that start around $5,000–$10,000 and can go much higher.
What drives the repair cost
Crack injection is priced per crack: materials (epoxy or polyurethane), labor for prep and injection, and access. The number and severity of cracks drive the total.
Simple hairline cracks may only need sealing. Structural or growing cracks need injection, and sometimes a structural engineer's assessment first.
- Number of cracks
- Crack width and length
- Epoxy vs polyurethane injection
- Access and prep work
- Water leakage or movement
Estimate by crack with materials and labor
The total is the number of cracks multiplied by the combined injection and labor cost per crack.

When it becomes a structural project
Bowing walls, major settlement, large horizontal cracks or drainage problems turn a repair into a structural project. These need an engineer, and often underpinning or wall stabilization — a different budget entirely.
Budget like a pro
Get a structural assessment for cracks that grow or move. Then get two or three repair quotes that include materials, labor and access.
