When to Call a Structural Engineer About Your Foundation
This guide explains when Oklahoma City homeowners should hire an independent structural engineer for foundation problems, how that differs from a contractor inspection, and cited engineer cost ranges.
A foundation repair company's inspection is often free and leads to a repair proposal. An independent licensed structural engineer evaluates the home without selling the repair, and can design a repair plan that contractors bid on.
Consider an Engineer When
- Movement is significant: wide or fast-growing cracks, large floor slopes or doors that no longer close.
- Contractors disagree on the cause, method or number of piers.
- You are buying or selling and need a documented opinion.
- An insurer, lender or city asks for an engineer's letter.
- A previous repair failed or the problem may be drainage or plumbing rather than soil.
- The repair involves structural framing, additions or retaining walls.
What It Costs
Published Oklahoma City estimates put a structural engineer evaluation at about $450–$900[2] or $300–$780[3]. A contractor inspection with written report is estimated at $0–$650[2].
What to Ask For
- A floor elevation survey and crack map.
- A written opinion on the cause (soil, drainage, plumbing or framing).
- Repair recommendations specific enough for contractors to bid on.
- Whether the engineer will review the final repair.
Verify any engineer's license with the Oklahoma State Board of Licensure for Professional Engineers and Land Surveyors before hiring.
