Figures reflect national-average foundation repair costs (HomeGuide, Angi, This Old House, 2025). It is a national-average estimate, not a quote. We give you an exact price after we look at the job.

Foundation repair costs anywhere from a few hundred dollars to well over $20,000, because the word covers everything from sealing a crack to lifting a settled house on piers. The national average is around $5,000, with most jobs landing between $2,200 and $8,000. The calculator above narrows that by the kind of problem you have.

The problem decides the price

There is no single “foundation repair” number, because the work ranges from a tube of sealant to lifting a house. The calculator lets you pick which problem you are seeing:

  • Sealing cracks or leaks. The most common and the least expensive, often a few hundred to a couple thousand dollars.
  • A wet basement. Usually a waterproofing job (interior drainage, a sump pump, sealing), not structural, and priced accordingly.
  • A bowing wall. Soil pressure is pushing the wall in. Anchors, braces, or carbon straps hold it, which is a bigger job.
  • Settlement. The house is sinking unevenly and needs piers to stabilize and often lift it. This is the top of the range.

Then set how extensive it is, since a single crack and a whole wall are not the same bill.

About these numbers

The ranges here are national averages, drawn from published cost data, not a look at your home. In the Miami Valley, clay soil, freeze-thaw, and a high water table shape which of these problems show up, and every basement is a little different. Use the estimate to get oriented, then let us put eyes on it. You get a clear written evaluation and a firm price before any work begins, with no scare tactics.

Diagnosis comes before the quote

The single biggest way people overspend on a foundation is by fixing the wrong problem: waterproofing a wall that is actually moving, or bracing a wall when the real issue is water. We start every visit by telling a foundation problem from a water problem, because that answer changes everything downstream, including the price.

When you want a real number, book an inspection and we will tell you plainly what you are dealing with.

Frequently asked questions

How much does foundation repair cost?
It depends entirely on the problem. Sealing a crack can run a few hundred to a couple thousand dollars. A bowing wall that needs anchors or braces often runs $4,000 to $12,000. Settlement that needs piers can reach $20,000 or more. The national average across all of it is around $5,000.
Why is the range so wide?
Because "foundation repair" is not one job. A hairline crack and a wall that is being pushed in by soil pressure are different problems with different fixes and very different price tags. The calculator narrows the range once you tell it which problem you are dealing with.
Is my problem a foundation problem or a water problem?
This is the most important question, and the two get mixed up constantly. A wet basement often needs waterproofing, not structural repair, which costs far less. A moving wall needs structural work. We figure out which one you actually have before quoting either, because fixing the wrong one is wasted money.
Does a small crack mean a big repair?
Not always. Plenty of cracks are cosmetic or a simple seal. What matters is whether the wall is moving, and that is something we check on the first visit. A calculator cannot tell a hairline from a structural crack, which is why the estimate here is a starting point, not a verdict.
