Foundation Repair Cost in Oklahoma City

The quick answer

Cost guides that survey contractors and homeowners put a typical foundation repair somewhere in the low thousands to low tens of thousands of dollars. These are published ranges from national sources, not quotes, and not what any one contractor will charge you:

• Angi (updated August 2026): an average of about $5,174, with most jobs between $2,225 and $8,133.
• NerdWallet: an average of just over $5,000, a typical range of about $2,200 to $8,100, and anywhere from a few hundred dollars to $100,000 at the extremes.
• Olshan Foundation Repair, a national contractor, publishes a 2026 national average of $11,950 on its cost page.
• HomeGuide: $4,500 to $20,000 to fix a settling or sinking foundation, and $10,000 to $30,000 or more for underpinning.

The spread is wide because "foundation repair" covers everything from sealing one crack to lifting a whole house. The rest of this page explains what moves your number up or down.

Before you think about price, it helps to know whether what you are seeing is likely a foundation problem at all. The symptom checker takes about a minute.

If you want a rough range for your own house first, the estimator below asks three things (foundation type, home size and what you are seeing) and shows where you are likely to land.

What drives the price

1. How many piers you need

A pier is a column driven or screwed into the ground under your foundation to hold it up (and often lift it back toward level). On most slab repairs the pier count is the single biggest line on the bill. Olshan says most slab jobs need 5 to 15 piers, depending on how much of the house is affected.

2. What kind of pier

Three types show up on Oklahoma City estimates:

• Pressed concrete piers: stacked concrete cylinders pushed into the ground with a hydraulic jack until they stop moving. They are generally the lower-cost option, but they do not go as deep as steel.
• Steel push piers: steel pipe sections driven down using the weight of the house, often until they reach dense soil or rock. Olshan lists these at roughly $990 to $1,350 per pier.
• Helical piers: steel shafts with screw-like plates, turned into the ground like a giant screw. Olshan lists these at roughly $3,500 to $4,400 per pier. They are often used for lighter structures or where a push pier can't get enough resistance.

3. Slab or pier-and-beam

A slab house sits on a poured concrete pad at ground level. A pier-and-beam house sits on posts with a crawlspace underneath. HomeGuide puts slab repair at $1,000 to $10,000 and pier-and-beam repair at $2,000 to $15,000 or more; Angi's range for pier-and-beam runs from $750 to $25,000. Pier-and-beam work often means shimming (adding thin steel or wood spacers to bring floors back to level) and replacing rotted wood, which slab houses don't have. Not sure which you have? Our pier-and-beam vs. slab guide explains how to tell.

4. Access

Piers along an open side yard are easier than piers under a patio, driveway or interior room. Interior piers may mean breaking through flooring and the slab, then patching it. Expect that to show up as its own line.

5. Drainage work

On clay soil, water management is often part of the fix, not an extra. Angi lists drainage system installation at $2,800 to $6,500 and poor-soil-drainage fixes at $800 to $15,000. HomeGuide puts regrading around a foundation at $500 to $5,000.

6. Engineer report and permit

Angi puts a structural engineer's report at $300 to $1,000; HomeGuide says $500 to $3,000. A soil report from a geotechnical engineer runs $500 to $3,000 according to Angi and NerdWallet. Both guides put typical permit fees at $75 to $150. The City of Oklahoma City says permits are required when you construct, alter or repair a structure, so ask whether your job needs one.

Per-pier math: a worked example

Say an inspection finds the back corner of a slab house has dropped and recommends 10 piers. Using Olshan's published per-pier ranges:

Line item	Steel push piers	Helical piers
10 piers	$9,900 to $13,500	$35,000 to $44,000
Structural engineer report (Angi range)	$300 to $1,000	$300 to $1,000
Permit (typical, per Angi and HomeGuide)	$75 to $150	$75 to $150
Subtotal before drainage or patching	$10,275 to $14,650	$35,375 to $45,150

Two lessons fall out of that table. First, the pier type matters more than almost anything else, so ask why a contractor chose it. Second, the pier count multiplies everything, so ask how they arrived at the number and where each pier goes. Also confirm whether the price is per pier location and exactly what each one includes.

How Oklahoma City's clay changes the scope

Much of the metro sits on expansive clay that swells when wet and shrinks when dry. Soil scientists measure this as LEP (linear extensibility percent): roughly how much the soil changes length between wet and dry. The USDA classes 3 to 6 as moderate and 6 to 9 as high.

Our ZIP-level soil data, built from the USDA NRCS soil survey, shows big differences across short distances:

ZIP	Area	LEP	Share on high shrink-swell soil
73159	South OKC	7.55	84%
73139	South OKC	6.93	79%
73120	Northwest OKC	6.70	75%
73160	Moore	5.89	66%
73034	East Edmond	2.32	5%
73020	Choctaw	2.07	2%

What this tends to mean for your estimate: on high-swell Kirkland and Renthin clays, contractors are more likely to recommend deeper piers that reach below the layer that wets and dries each season, and more likely to pair them with drainage or moisture control. On the sandier Stephenville and Harrah soils of the east side, movement is often smaller and the cause is more often a specific water source. This is a tendency, not a diagnosis. Only an on-site inspection can tell you what your house needs.

Dry years matter too. As of October 20, 2026, all of Oklahoma County was in severe drought (D2) or worse, per the US Drought Monitor, and 2026 has had 34 weeks with at least half the county in D2 or worse, the most since 2011. Shrinking clay is a common reason cracks show up in a drought. See drought and your foundation for more.

Cheaper fixes that sometimes come first

Not every crack needs piers. If the movement is small and tied to water, these lower-cost steps may be part of the plan, or the whole plan:

• Gutters and downspouts: NerdWallet puts gutter installation at $4 to $40 per linear foot, or about $2,000 to $6,000 to replace gutters on an average home.
• Downspout extensions and watering habits: Colorado State University Extension advises keeping sprinkler spray at least five feet from the foundation, planting trees at least fifteen feet away, and leaving downspout extensions in place.
• Regrading: $500 to $5,000 per HomeGuide, so the ground slopes water away from the house.
• Crack sealing: $250 to $800 per crack per HomeGuide and Angi. This seals the crack but does not stop movement.
• Mudjacking or slabjacking: pumping a cement mix under a sunken slab to raise it. HomeGuide lists $4 to $9 per square foot; Angi lists $500 to $1,300 for a typical job.

A good inspection should tell you whether the cheaper fix is enough, and say so in writing.

Paying for it

Most homeowners pay with savings, a home equity loan or line of credit (HELOC), a personal loan, or financing offered through the contractor. NerdWallet notes that home equity loans usually carry lower rates but take longer because of underwriting and appraisal, while personal loans can fund within about a week at higher rates. The FTC warns against accepting contractor-arranged financing without comparing loan terms elsewhere. Homeowners insurance usually does not cover foundation damage from soil movement over time; see does insurance cover foundation repair. This is general information, not financial advice.

How to compare written estimates line by line

The Oklahoma Construction Industries Board suggests getting at least three estimates and notes the lowest may not reflect the quality of materials. Lay them side by side and check each of these:

1. Pier type and target depth. Pressed concrete, steel push or helical? Driven to a set depth or to a load or refusal point?
2. Pier count and a drawing. Where does each pier go, and why there?
3. Price per pier and what it includes. Excavation, brackets, backfill, haul-off.
4. Lift. Does the price include lifting, and to what tolerance? Is a before-and-after elevation survey included?
5. Interior work. Breaking and patching slab or flooring, and who repairs drywall cracks afterward.
6. Drainage. Is it in the scope, recommended separately, or not mentioned?
7. Engineer and permit. Who pays, and is it included?
8. Plumbing test. Lifting a slab can stress pipes. Is a plumbing check before or after included?
9. Warranty. What it covers, how long, and whether it transfers to a buyer.
10. Payment schedule. The FTC advises against paying the full amount up front and says never to make the final payment until the work is done and you are satisfied.

If two estimates differ by thousands, the answer is usually in lines 1, 2 or 6. Our guide to choosing a foundation repair company lists the questions to ask in person.
