How Much Does Foundation Repair Cost? A Plain-English Guide

"How much does foundation repair cost" doesn't have one honest answer — it depends entirely on what's actually wrong, and that's genuinely not something anyone can tell you accurately without looking at the house. What follows is real national cost data as a reference point, plus what actually drives the number up or down.

National average cost (2026 data)

According to Angi's 2026 cost data, the national average for foundation repair is around $5,175, with most homeowners spending somewhere between $2,225 and $8,135. That's a wide range, and for good reason — it covers everything from a single cosmetic crack to a full underpinning job.

Cost by type of problem

Angi's data breaks down cost ranges by what's actually being fixed:

• Crack repair: roughly $250–$800 for straightforward crack injection work.
• Leak repair: roughly $2,000–$7,000, depending on how extensive the water intrusion is.
• Settling or sinking foundations: roughly $5,000–$25,000, since this is usually where piers or underpinning come in — the most involved and most expensive category.

These are national figures, not St. George-specific ones — we don't have a reliable local average to cite, and we'd rather tell you that than make one up. Local cost can run higher or lower depending on soil conditions, site access, and the specific repair method a given home needs.

What actually drives the price

• Repair method. Epoxy crack injection is inexpensive. Push piers or helical piers that carry a foundation's load down to stable soil cost significantly more, because they're a bigger structural job.
• How many piers or how much of the foundation is affected. A single corner settling is a smaller job than a foundation moving along its full length.
• Access. Equipment that can pull right up to the work area costs less than a job that requires hand-digging because of tight side-yard access or landscaping in the way.
• What's causing it. If the underlying cause is collapsible or gypsiferous soil, addressing the soil itself (not just the symptom) can add to the scope — but it's also what keeps the problem from coming back.

Why we don't quote a price without seeing the house

Any number given over the phone without an inspection is a guess, and we'd rather not guess with something this expensive. A free inspection identifies the actual cause and the actual scope of work first — that's what an accurate, honest number has to be based on.
