Foundation repair: common fixes, prices and who to ask
Foundation repair runs from sealing a single crack to setting steel or helical piers under part of a house. The right fix depends on what is moving and why. That is why an on-site assessment comes before any price.
Common repair methods
- Crack injection. Fills and seals a crack in a slab or wall. Priced per crack.
- Steel push piers and helical piers. Installed under the foundation to support it. Priced per pier. Angi’s July 2026 underpinning guide bases its whole-job price on about ten piers.
- Drainage. Moves water away from the foundation when wet soil is part of the cause.
The foundation repair cost guide lists the published range for each method, taken from national cost guides.
Repair company or engineer first?
The normal first step is an assessment by a foundation repair company. It shows what is moving, which repair fits and what it costs. Ask for an itemized quote to compare with other companies.
An independent structural engineer is an option in three cases:
- the problem is complex or disputed
- two companies propose very different repairs
- a lender, buyer or insurer wants a written report
National guides checked in October 2026 list $300–$750 for a structural engineer’s foundation inspection (HomeGuide) and $300–$1,000 for a structural report (Angi). Ask whether the fee covers the inspection, a written report or both.
Oklahoma’s Construction Industries Board does not license foundation repair. General contractors do not need a state license either, though cities can set their own contractor and permit rules. Ask each company:
- how long it has worked in your area
- whether your job needs a city permit and who will pull it
- what its written warranty covers
Local soil and permit pages
Housing age, clay soil and local permit rules are on the pages for Bartlesville, Bethany, Broken Arrow, Choctaw, Claremore, Del City, Edmond, Moore, Mustang, Norman, Sapulpa and Shawnee.
Start with an assessment
A quote request goes to a local repair company that serves your area. When it looks at the cracks, doors or floors that worry you, ask it to explain the cause it found. Ask which method it recommends, and why. Then ask it to put these in writing:
- the price per crack or per pier
- any drainage work
- any permit fee
