Engineer or foundation company inspection
Foundation repair companies often offer a free inspection. It can be useful, but the person inspecting also sells the repair. A structural engineer charges for the inspection and has nothing else to sell you. This Old House makes this point: the engineer gives an unbiased assessment.
On a job that could cost $5,000 to $15,000 or more, see our foundation repair cost page, a $600 report is cheap insurance. It tells you whether you need piers, drainage work or nothing at all, and it gives the repair contractors a clear scope to bid on.
Before you buy a house
A general home inspector will flag cracks and sloping floors but will not diagnose the cause. If the home inspection raises a foundation concern, a structural engineer's report is the next step, and it is often a strong tool when you negotiate.
Why this costs more in 2026
An inspection is a trip and a few hours of an engineer's time. The trip is the part that moved.
Every truck trip costs more now. Diesel passed $6 a gallon in September 2026 (CBS 8 reporting AAA), and material costs rose 4.8 percent in a year (Roofing Contractor). Quotes may only hold for a few weeks.
How to judge the quote in your hand
- Hire a licensed structural engineer. Not a salesperson.
- Ask what the report includes. Cause, fix and a rough cost.
- Ask if the report is stamped. Some lenders and cities want it.
- Get the fee in writing before the visit.
Ways to pay less
- Use the report to get bids on the same scope.
- Ask the seller to pay in a home purchase.
- Skip it for a single hairline crack with no other signs.
- Ask for a re inspection price after the repair.
