This foundation repair cost calculator gives you a typical range based on 2026 prices. Use it to get a sense of the budget before you talk to anyone. It's not a quote, because nobody can price a repair without measuring the house first.
How this foundation repair estimator works
This foundation repair estimator starts with a typical price range for the problem you pick. Then it adjusts that range using three things: your foundation type, your home's size and how bad you say it looks. It rounds the result to the nearest $100.
Basements and slabs cost a little more because they're harder to reach. Pier and beam homes cost a little less, since crews can work directly under them. A bigger house raises the number, though only up to a point. A foundation problem doesn't always get bigger just because the house does.
If you pick "Not sure" for severity, the range widens by 25% on each side. That's the honest way to show that we don't know yet. You can use it as a foundation repair estimate calculator for a few scenarios, by changing your answers and seeing how much the number moves.
Why your real price may be different
Your real price may be different because a calculator can't see your house. Here are the main things it doesn't know:
- How deep firm soil is. Two neighbors can need very different pier depths.
- What's causing the problem. A plumbing leak or a bad gutter can change the plan.
- How easy it is to get to. Decks, tight lots and low crawl spaces all add labor.
- What's already damaged. Rotted wood and termites can add a lot.
- Local permits. Some cities need them for structural work.
Things can also go the other way. Plenty of people expect a big bill and find out the crack's cosmetic, or that a fix to their drainage takes care of most of it. Here's more about what most repairs actually run, by job type.
Use it for house leveling and pier and beam homes too
You can use this as a house leveling cost calculator by choosing "Sinking or settling" or "Sagging floors" as your problem. It also works as a pier and beam foundation cost calculator if you select that foundation type. Raised homes often land lower in the range, since most of the job is shims and labor.

Calculator questions
How accurate is a foundation repair estimator?
It's good for a rough range and that's about it. It can't see your soil, your access or how many piers you actually need. Real prices can land outside the range. Use it to plan a budget, then get a written estimate based on real measurements.
What information do I need for an accurate estimate?
Your foundation type, the problem you're seeing, your home's rough square footage and how long it's been going on. Photos with dates help too. For a real estimate, someone needs floor readings, crack measurements and a look at drainage and access, which we include in a free inspection.
Why does the calculator show such a wide range?
Because the same problem can have very different causes. A crack might need a $250 seal or a whole set of piers. The range reflects that. Picking a severity level narrows it somewhat, but you won't get a tight number until someone measures your house.
Does the calculator include cosmetic repairs?
No, it covers the structural and moisture work. Drywall patching, paint, tile and landscaping usually come after that, and they depend on your finishes. Set aside a little extra for those. Interior piers can especially add flooring work that isn't in these numbers.
Do you save the answers I enter?
No, the calculator runs in your browser and doesn't send anything to us. We only get your information if you fill out the inspection form. Then the problem and foundation type carry over, so you don't need to type them again, and you can change them.
Can I use this if I'm buying a house?
Yes, it's handy for a first look when you're negotiating. Just don't rely on it for your final numbers. Before your inspection contingency or option period ends, get a written estimate from someone who has actually measured the floors, since that's what will hold up with a seller.
What does severity mean in the calculator?
It's your rough sense of how bad things look. Minor means small and stable, moderate means you can clearly see it and severe means it's affecting how the house works, like doors that won't close. Choose Not sure and the range widens to reflect that.
