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.
Fuel is the common thread. AAA's national average for diesel passed $6 a gallon for the first time on September 11, 2026, up from about $3.70 a year earlier (CBS 8 reporting AAA). Every truck roll and every delivery carries that. Materials moved too. Associated Builders and Contractors reported construction input prices up 4.8 percent in a year as of March 2026, the largest annual gain since January 2023, and the Associated General Contractors said diesel jumped 37.8 percent in one month, the largest one month rise since 1990 (Roofing Contractor, April 2026). Some suppliers added freight surcharges this year. Ask how long your quote is good for.
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.
