Who inspects, and what it costs
The stamped report is the product that matters. It documents elevations, crack mapping, probable cause, and a repair scope — signed by a licensed PE with no stake in the repair. It’s what a lender accepts at closing, what turns a vague $30,000 pier quote into a defined scope you can re-bid, and what stands up when an insurance adjuster says “long-term settling.”
The order that saves money
Engineer first, contractor second. Homeowners who start with free contractor inspections routinely collect three quotes with three different pier counts and no way to judge them. Starting with a $350–$1,000 engineer’s report flips the dynamic: contractors bid against a fixed scope, and quite often the report’s verdict is that no structural repair is needed at all — the cheapest possible outcome of the whole process.
Frequently asked questions
How much does a foundation inspection cost?
A licensed structural engineer charges about $350–$1,000 for a foundation inspection with a written, stamped report — more for large homes or crawl space access. A plain verbal walk-through can be cheaper; foundation repair contractors will usually inspect for free.
Why pay an engineer when contractors inspect for free?
Because the free inspection is a sales visit. A repair contractor is paid by the repair, so ambiguous cracks tend to become pier quotes. An engineer sells you the diagnosis itself: they profit the same whether the answer is “monitor it” or “underpin the corner,” and their stamped report is what banks, buyers, and insurers actually accept.
When do I actually need a foundation inspection?
Get an engineer involved when doors and windows start sticking together with new cracks, when a crack is wider than about 1/4 inch, is horizontal, or is growing, when you’re buying or selling a house with visible foundation red flags, or before signing any repair quote in the tens of thousands.
Does a home inspection cover the foundation?
Only visually. A general home inspector ($300–$500 for the whole house) will note cracks and moisture they can see, but they don’t measure elevation, diagnose cause, or produce a structural opinion. If the general inspection flags the foundation, the next call is a structural engineer.
Will insurance pay for the inspection?
If you’re filing a claim for sudden damage from a covered peril, the insurer sends its own adjuster; your own engineer’s report is an out-of-pocket expense — and often the best money in the whole claim, since a stamped independent report is what disputes a lowball or a denial.
