The engineer's report says twelve piers. The first contractor says eighteen thousand dollars. The second says thirty one. The third says the whole side of the house and will not quote until somebody digs. You are trying to work out whether this is a repair you make or a house you sell, and none of the numbers agree.
This article sets out what foundation work actually costs in the Tulsa area, why quotes vary so widely, what drives the number up, and how to tell which of the three decisions in front of you is the right one.
We buy houses with foundation problems, so read the last section knowing that. We are not engineers or foundation contractors. Costs here are ranges for this market rather than quotes, and what your house needs is a question for a structural engineer who has looked at it.
Why this happens here so much
Expansive clay. It swells when wet and shrinks when dry, and Tulsa gives it both extremes within a single year. A foundation sitting on it moves seasonally, and where the moisture is uneven, one part moves more than another. That differential is what cracks things. Our article on why Tulsa houses move covers the mechanism in full.
It is worth knowing that a great many houses here have moved slightly and are fine. Movement is not automatically damage, and our article on which cracks matter is the place to start before assuming the worst.
What it costs
These are ranges for the Tulsa market. Get three written itemised quotes and do not treat any single number, including these, as your number.
| Work | Typical range |
|---|---|
| Engineer's evaluation and report | $400 to $1,200 |
| Drainage correction, gutters and regrading | $500 to $4,000 |
| Crack injection, cosmetic | $400 to $1,500 |
| Piers, one or two elevations | $4,000 to $12,000 |
| Piers, full perimeter | $12,000 to $30,000 |
| Slab lifting or mudjacking | $1,500 to $6,000 |
| Interior drain and sump | $4,000 to $12,000 |
| Making good afterwards: drywall, paint, flooring, doors | $2,000 to $10,000 |
The last line is the one people forget. Piering lifts the house, which reopens every crack the movement closed and every door the movement jammed. Ask whether making good is in the quote, because frequently it is not.
Why quotes vary by a factor of two
- Pier count and depth. The single biggest variable, and contractors reach different conclusions from the same house
- Pier type. Pressed concrete, steel push, helical. Different products, different prices, different warranties, and our article on repair methods compared sets them against each other
- Access. A pier under a patio, a mature tree or an air conditioning condenser costs more than one on open ground
- What the quote includes. Excavation, backfill, landscaping restoration, making good inside. Cheap quotes commonly exclude several
- Who specified it. A quote written by the contractor selling the repair is a different document from one priced against an independent engineer's scope
Get the engineer first
Four hundred to twelve hundred dollars for an independent structural engineer buys you a scope that every contractor then bids against the same way. Without it you are comparing three different jobs and calling it comparing prices. It is the single best value item on the list.
The warranty question
Most foundation contractors offer a lifetime or long-term warranty. Two questions decide whether it is worth anything to you.
Does it transfer to a buyer? Some do automatically, some for a fee, some not at all. A transferable warranty is a genuine asset at sale; a personal one is not. Our article on transferable warranties covers what to check.
Is the company likely to be there? A lifetime warranty from a contractor who closes in four years is a piece of paper. Ask how long they have traded in Tulsa.
The three decisions, and how to tell them apart
Repair and keep. Right when the cost is fundable, the house otherwise suits you, and the engineer's scope is contained. Foundation repair is not a reason to leave a house you want.
Repair and sell. Right when the work is contained and you can fund it, and you were selling anyway. It removes an objection that frightens buyers disproportionately. Be clear that it removes an objection rather than adding its cost to the price.
Sell as it stands. Right when the number is beyond reach, when it keeps growing as contractors look closer, when a financed sale has already failed on it, or when you are managing this from another state. Our page on selling a house with foundation problems covers how that works.
Why a financed sale fails on this
Worth understanding because it changes the arithmetic. Where an appraiser flags structural movement on a government backed loan, the lender typically wants an engineer's evaluation before closing, and sometimes the repair completed before funding.
That puts the seller in the position of paying for a repair to enable a sale they have not closed yet, to a buyer who may still walk. A proportion of buyers do walk rather than wait, which is why houses with structural findings frequently sell for cash even where the owner could technically have funded the work.
Where we come in
We buy houses across Tulsa and the surrounding towns with foundation movement, previous pier work, pier work whose contractor has since closed, and engineer's reports the owner never acted on.
Straight answer: if the engineer's scope is contained and you can fund it, repair it. You will net more, and we would rather tell you that than take a house cheaply from somebody who had a better option. Send us the engineer's report if you have one; it makes our estimate more accurate and it frequently makes our number better rather than worse.
Where we make sense is when the number is out of reach, when it keeps growing, or when a financed sale has already collapsed on it. Our offer process is free and the net proceeds calculator lets you test repairing and listing against selling as it stands.
The short version
- Expansive clay plus Tulsa's wet and dry extremes is why this is so common here
- Movement is not automatically damage. Establish which cracks matter before assuming
- An independent engineer's report costs $400 to $1,200 and is the best value item on the list, because it gives every contractor the same scope to bid against
- Piers on one or two elevations commonly run $4,000 to $12,000; a full perimeter $12,000 to $30,000
- Making good afterwards is $2,000 to $10,000 and is frequently excluded from quotes
- Quotes vary by a factor of two because of pier count, pier type, access and what is included
- Ask whether the warranty transfers to a buyer and how long the company has traded here
- A financed sale can fail on a structural finding, which puts the seller in the position of funding a repair for a sale that has not closed
Frequently asked questions
How much does foundation repair cost in Tulsa?
Piers on one or two elevations commonly run $4,000 to $12,000 and a full perimeter $12,000 to $30,000, with making good afterwards adding $2,000 to $10,000. Those are ranges for this market, not a quote for your house.
Why do foundation quotes vary so much?
Pier count and depth, pier type, access, and what the quote includes. A quote that excludes excavation restoration and interior making good looks cheaper than one that includes them.
Should I get an engineer before contractors?
Yes, and it is the best value item on the list. $400 to $1,200 buys an independent scope that every contractor bids against the same way. Without it you are comparing three different jobs.
Is a contractor's free inspection the same as an engineer's report?
No. A contractor inspection is done by the party selling the repair. An independent engineer has no interest in the scope being larger than it needs to be.
What is making good, and why does it matter?
Repairing the drywall, paint, flooring and doors after the house is lifted. Lifting reopens cracks the movement closed, and this line is commonly excluded from quotes.
Do all cracks mean foundation problems?
No. Many Tulsa houses have moved slightly and are fine. Width, direction, location and whether a crack is changing all matter, and our article on which cracks matter covers it.
What is the cheapest thing I can do?
Drainage. Gutters discharging away from the house and ground sloping away, commonly $500 to $4,000. It addresses the cause rather than the symptom and it is necessary whether or not you pier.
What are the different pier types?
Pressed concrete, steel push and helical are the common ones. They differ in cost, in the conditions they suit and in warranty terms, which our repair methods article compares.
Does a foundation warranty transfer to a buyer?
Some do automatically, some for a fee, some not at all. A transferable warranty is a real asset at sale and a personal one is not. Ask before signing.
What if the company that did the work has closed?
The warranty is generally worthless. It is one reason to ask how long a contractor has traded here before relying on a lifetime guarantee.
Will foundation repair increase my house's value?
It removes an objection rather than adding its cost to the price. On a house that is otherwise sound that can be worth more than the return figure suggests, but do not expect to recover the spend.
Can I sell a house with foundation problems?
Yes. A financed buyer may struggle, because a structural finding can mean the lender wants an engineer's evaluation or the repair completed before funding. That is why these houses commonly sell for cash.
Do I have to disclose foundation work?
Oklahoma places disclosure obligations on residential sellers regarding known defects, and both movement you know about and repairs you had done are knowledge. The specifics belong to a real estate attorney.
Should I repair it before selling?
If the scope is contained and you can fund it, frequently yes. If the number is beyond reach, keeps growing as contractors look closer, or a financed sale has already failed on it, repairing for a sale that has not closed is a real risk.
What does an engineer's report actually say?
What the movement is, what is causing it, and what scope of repair is warranted. It is the document contractors bid against and the one a buyer's lender will want to see.
Is mudjacking the same as piering?
No. Mudjacking or slab lifting raises a settled slab and commonly runs $1,500 to $6,000. Piers support the foundation on stable ground below. They solve different problems.
Why does a lender care about foundation movement?
Because the collateral has to be sound. On a government backed loan a structural finding typically triggers a requirement for an engineer's evaluation before closing, and sometimes the repair itself.
How long does foundation work take?
Days rather than weeks for a typical pier job, plus making good afterwards. The longer part is usually getting the engineer, the quotes and the scheduling lined up.
Will you buy a house that has already had pier work?
Yes, and previous work is not a negative. Send whatever documentation exists, including the warranty, because a transferable one has value we can account for.
Should I send you the engineer's report?
Yes. It makes our repair estimate more accurate, and an accurate estimate frequently improves the number rather than reducing it. Guessing is what makes an offer conservative.
What if three contractors give three different scopes?
That is the normal outcome without an independent engineer, and it is exactly the problem the engineer's report solves. Get the scope first, then price it.
Can drainage alone fix it?
Sometimes, where movement is recent and driven by uneven moisture. It will not reverse settlement that has already happened, but it can stop it continuing, which is why it is worth doing whether or not you pier.
We buy houses with foundation problems, so read the last section knowing that. We are not engineers or foundation contractors. Costs here are ranges for this market rather than quotes, and what your house needs is a question for a structural engineer who has looked at it.
