The short answer
Foundation repair cost is set by the scope: the method, the number of piers, the depth to competent soil, access, permits and what gets put back afterward.
The same crack can need a downspout extension or two dozen piers driven thirty feet, so no national average holds. Have several contractors price one specified scope, with an overage rate per extra foot in writing.
Key takeaways
Depth to bearing, soil, access and method vary enough between two houses on one street that a single figure misleads.
Get the overage rate per additional foot in writing.
Steel pipe and tube is up about 14% year over year; ready-mix concrete about 2%.
Anyone quoting you a national range is quoting a marketing page.
How to actually compare bids
Total against total is the one comparison that tells you nothing.
Ideally the engineer’s. Three bids against three self-generated diagnoses are not three bids.
Method, pier count, individual locations, assumed depth, overage rate, target lift, plumbing testing, permitting, reinstatement.
Reinstatement, landscaping, hardscape, crack repair, door adjustment and plumbing repair are the usual omissions, and they are not small.
What does the drainage-only option cost, and what does the engineer think of it? If nobody offered you one, ask why.
A cheaper bid at a shallower assumed depth is not cheaper; it is a smaller job that may stop short of bearing soil.
A transferable warranty from a long-established entity is worth more than a lifetime promise from a company formed last year. See what a warranty is worth.
Some states cap home-improvement deposits by statute. A large payment before work starts, to a company you have not checked with the Secretary of State, is the shape of most complaints in this trade.
Why prices have moved, with the actual indexes
The US Bureau of Labor Statistics publishes Producer Price Index series covering the materials this trade runs on — documented, methodologically transparent and identifiable by series ID. They do not tell you what your job costs.
They do answer "why is this more than it was", which is a question nobody else in this market answers with data.
Comparing August 2026 with August 2025: ready-mix concrete (series WPU1333) rose about 2.3%, while steel pipe and tube (WPU101706) rose about 14.3% and steel mill products (WPU1017) about 23.4%. Fabricated structural metal products (WPU107) rose about 6.5%.
Push piers and helical piles are steel. Pressed and drilled concrete piers are mostly concrete. The divergence above means the relative pricing between methods has shifted over the last year, and it is not because anyone changed their margin.
From January 2021 to August 2026: ready-mix concrete rose about 38%, steel pipe and tube about 52%, and fabricated structural metal products about 68%. A quote you were given three years ago is not a benchmark for one you are given today.
BLS Occupational Employment and Wage Statistics for May 2025 put the median annual wage for cement masons and concrete finishers at $57,020 and for construction laborers at $47,120. Those are wages, not billed rates — a contractor’s rate carries overhead, insurance, equipment and profit on top.
We publish no engineering fee range because no free authoritative survey of residential engineering fees exists; the ranges you will find are marketing pages citing a paid commercial survey.
What we can publish is that BLS classifies structural engineers within civil engineers, whose median annual wage was $100,840 in May 2025, with the 75th percentile at $129,680. Again a wage, not a billed rate.
All series above are not seasonally adjusted. August 2026 values carry the BLS preliminary footnote and may be revised for up to four months. There is no PPI series for foundation repair or for residential foundation contracting, so nothing here is a direct index of your job — these are input costs.
The line items that move the number
Roughly in order of how much they swing a total. Note that the first two are decided before a contractor is involved.
| Option | What it means for you |
|---|---|
| Diagnosis and engineering | The assessment, the elevation survey and the specified scope. The smallest line on this list and the one that governs every other line — including the possibility that most of them are unnecessary. |
| Method | Push piers, helical piles, pressed pilings, drilled piers, slab lifting, wall stabilization or drainage. Different equipment, different crews, different orders of cost. See repair methods. |
| Number of piers | Driven by the affected length of foundation and the loads on it — not by the number of cracks you can see. |
| Depth to bearing | How far down competent soil is, and it varies across a single lot. The line most likely to change mid-job, and the reason an overage rate per foot belongs in the contract. |
| Access | Interior work means cutting and reinstating floors. Exterior work means excavation, landscaping and sometimes removing hardscape. The same pier costs different money at different ends of a house. |
| Soil and site | Expansive clay, fill, slope, water table. Dense granular soil can offer too much driving resistance for pressed pilings at all. This is why bids on visually identical houses differ. |
| Plumbing testing | A static test before and after, plus any repair it uncovers. Particularly relevant under slabs, where lifting over a leaking line can break more of it. |
| Permitting and inspection | The permit, the sealed calculations and any special inspection required during installation. Frequently omitted from a bid and not optional. |
| Making good | Cracks filled, doors rehung, floors, landscaping and hardscape restored. Commonly excluded, commonly assumed to be included. |
A bid that does not state method, pier count, individual locations, assumed depth and the overage rate is not comparable with one that does — at any price.
The cheapest useful thing you can buy is the scope.
An engineer’s specified scope is usually the smallest line in a foundation project, and the only one that makes the others comparable. It often shows the rest of the budget was not needed.
A drainage correction and a re-survey in six months is a common outcome of an independent assessment, and a rare one from a free inspection.
What to ask before you sign
Specifically: reinstatement, landscaping, hardscape, crack repair, door adjustment, plumbing.
The full checklist is on choosing a foundation contractor.
Where this goes wrong
The ranges you will find come from lead-generation sites whose business is selling your inquiry, not from any survey with a methodology. We do not republish them, which is why there is no number at the top of this page.
The single most expensive habit in this trade. Two numbers for two different scopes are not a comparison.
Depth to bearing is the commonest change order in foundation work. Without a rate per additional foot in the contract, you negotiate with the pits already open.
It is the line that determines whether the other lines exist. Removing it to save money removes the only independent check on their size.
Floors, landscaping, hardscape, cracks and doors are routinely excluded. Read the exclusions before the price.
Recovering elevation is a separate, more expensive and riskier decision from stabilizing, and many engineers advise against it.

A straight answer first. Matching is still being built, so this is not an instant quote. If a wall is moving or a door frame has racked out of square this week, call a structural engineer first.

Primary-source research and fact checking
We read the model building code, the federal soil and moisture guidance and the insurer position ourselves, and we publish each figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we say so instead of printing it. HyreFoundation does not inspect, engineer or repair foundations. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from the International Residential Code, Chapter 4, as the model code. Soil statements come from USDA and USGS. Insurance statements come from the policy language and the Insurance Information Institute. We open the source rather than cite a blog that cites it.
- The code is a model, and adoption is local. Your jurisdiction adopts an edition and amends it, and foundation chapters are amended more than most because frost depth and soil are local facts. Every code figure says so.
- We hold no job data. We have no dataset of bids, pier counts or invoices, so no page claims an average from one. Calculators show the arithmetic and the inputs they assumed, and label the result as an estimate.
- We do not diagnose your house. A crack guide can tell you which pattern to measure and when to call a structural engineer. It cannot tell you whether your foundation is failing. An engineer on site does that work.
- We do not repair foundations, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
