There's no national price list for a structural engineer's foundation inspection; the fee depends on whether you want a visual opinion, a written report or a repair design. As one public benchmark, Connecticut's crumbling foundations program reimburses a licensed engineer's visual inspection up to $400. Call an engineer first for horizontal, bowing, offset, wide or block stair-step cracks, and a repair contractor once you know what the repair is.
For most foundation cracks the order is simple. Get the diagnosis from someone who doesn’t sell repairs, then get repair bids against it.
What does a structural engineer foundation inspection cost?
It depends on the scope you order, and there’s no national price to quote. The one public figure we found is a reimbursement cap: Connecticut’s crumbling foundations program pays back a visual inspection by a licensed professional engineer at 100% up to $400 (opens in a new tab).
The same program reimburses core testing, where samples of the concrete go to a lab, at 50% up to $2,000. Those caps are for one state’s program on one kind of damage, so treat them as a sense of scale, not a quote. They do show that a visual visit and lab testing are priced very differently.
What moves an engineer’s fee:
- Visual opinion or written report. Connecticut defines a visual test as the engineer’s expert opinion based on education, observation and prior experience. A written report with measurements takes more time.
- Measurements. Mapping cracks, checking walls for plumb and measuring floor levels adds time on site.
- Repair design. If you need bracing or anchors, the drawings and specifications contractors will bid on are extra work.
- Testing. Core samples and lab work add the most. Connecticut’s cap for core testing is five times its cap for a visual visit.
- Follow-up. Some engineers will check the finished repair. Ask whether that’s included.
Who to call for foundation cracks
Call a structural engineer first for any crack that suggests the wall moved. For a stable vertical crack in a poured wall, you can skip the engineer and seal it yourself or hire an injection contractor.
| Crack or sign | Call first | Then |
|---|---|---|
| Thin vertical crack, poured wall, flush edges, dry | Nobody; monitor it | Seal it if you like |
| Same crack, leaking | You, or an injection contractor | Fix the water outside too; see the leaking crack guide |
| Vertical crack wider than 1/4 inch | Structural engineer | Contractor bids on the report |
| One edge sticks out past the other | Structural engineer | Contractor bids on the report |
| Horizontal crack | Structural engineer | Contractor bids on the report |
| Bowing wall | Structural engineer | Contractor bids on the report |
| Stair-step crack in a block wall | Structural engineer | Contractor bids on the report |
| Doors sticking, floors sloping, cracks in several places | Structural engineer | Contractor bids on the report |
If you’re not sure which row you’re in, the when to worry checklist walks through the signs.
Engineer vs contractor vs home inspector: what’s the difference?
A structural engineer diagnoses the cause and designs the repair. A foundation repair contractor builds a repair and sells it. A home inspector reports what’s visible and refers you on, without judging whether the structure is adequate.
| Structural engineer | Repair contractor | Home inspector | |
|---|---|---|---|
| What they do | Find the cause, judge whether the wall is sound, design the repair | Install the repair and quote the price | Inspect the visible foundation and report defects |
| Sells the repair | No | Yes | No |
| Says whether the structure is adequate | Yes | Not as an independent opinion | No, the standards exclude it |
| Licensed by | Your state engineering board | Your state or local contractor rules | Varies by state |
| What you get | An opinion or a written, signed report | A quote, then the work and a warranty | A home inspection report |
The home inspector’s limits are written into the trade’s own standards. InterNACHI’s Standards of Practice (opens in a new tab) have the inspector inspect the foundation, but say the inspector isn’t required to report on the adequacy of any structural system or offer engineering services. ASHI’s Standard of Practice (opens in a new tab) says the same: no engineering analysis and no opinion on the adequacy of structural components.
So when an inspection report recommends a structural engineer, the inspector isn’t dodging. The question is outside what a home inspection covers.
Why call an engineer before a repair contractor?
Because the contractor who diagnoses your wall also sells the fix. That doesn’t make the diagnosis wrong, but it isn’t independent, and a free inspection usually ends in a quote for the company’s own system.
An engineer has nothing to install, so the report answers the question you actually have: is the wall moving, why, and what repair does it need. For serious wall movement, ASHI’s guide to basement cracks says the repair needs an engineer’s design (opens in a new tab).
The report also makes contractor bids comparable. Three companies bidding on the same engineer’s design give you three prices for one repair, instead of three different repairs.
What does a structural foundation inspection include?
At minimum, the engineer looks at the cracks and the walls and gives an opinion on the cause and whether the wall is moving. Beyond that, what you get depends on what you order, so agree on it before the visit.
Ask whether the visit will include:
- A walk of the inside and outside of the foundation, including the grading and gutters
- Crack widths and locations, recorded with photos
- Checks of the walls for plumb and bowing, and of the floors for level
- An opinion on the cause and whether the movement is active
- A repair recommendation, or a repair design contractors can bid on
- A written report, signed and sealed by the engineer
- A follow-up visit to check the finished repair
A written report is worth paying for if you’ll sell the house, file a claim or hire a contractor. The repair cost guide covers what the repair itself costs to bid out.
How do you find a licensed structural engineer?
Look for a professional engineer licensed in your state, then confirm the license with the state engineering board. The NCEES directory links to every state’s board.
- Find your state board in the NCEES member licensing board directory (opens in a new tab), which lists the boards for all 50 states, the District of Columbia and the territories.
- Search for engineers who do residential foundation evaluations in your area, and ask each whether they work for repair companies or only for owners.
- Confirm each license is active on the state board’s website, or call the board if it has no online lookup.
Connecticut’s program, for example, requires visual inspections to be done by a Connecticut licensed professional engineer (opens in a new tab). Your state’s rules may differ, so check with your board.
What should you ask an engineer before you hire one?
Ask what you’ll get, what it costs and whether they have any tie to a repair company. Those three answers tell you whether the visit is worth booking.
- Do you do residential foundation evaluations?
- Is the fee fixed, and what does it include: a verbal opinion, a written report, a repair design?
- Will the report be signed and sealed?
- Do you work for, or get paid by, any foundation repair company?
- Will you review contractor bids or check the finished repair, and what does that cost?
- How soon can you come out, and how soon will I get the report?
What happens after the engineer’s report?
You get repair bids against it. Give every contractor the same report and ask each to price that repair, not their own idea of it.
The Federal Trade Commission’s advice on home improvement contracts (opens in a new tab) applies: get several written estimates, don’t automatically take the lowest, confirm the contractor’s license with your state or county, ask for proof of insurance and don’t pay the full amount up front. Scammers often ask you to get the building permits yourself, according to the FTC, so expect the contractor to pull them.
If the engineer says the crack is stable and only needs sealing, that’s often a DIY job. The foundation crack repair guide covers it, and the foundation crack hub links every crack type.
Questions
Is a free foundation inspection from a repair company good enough?
It's good for getting a quote. It isn't independent, because the company that diagnoses the wall also sells the repair. For a crack that might be structural, pay for an engineer's opinion and use it to get bids.
Can a home inspector tell me if my foundation is safe?
No. Both the ASHI and InterNACHI standards say a home inspector isn't required to judge whether a structure is adequate or to provide engineering services. A home inspector can point out the crack and refer you to an engineer.
Do I need an engineer for a hairline vertical crack?
Usually not. A thin vertical crack in a poured wall with flush edges is the common shrinkage kind, and you can seal it yourself if it leaks. Watch it with the crack monitoring guide, and call an engineer if it widens, offsets or turns sideways.
Does homeowners insurance pay for the engineer?
It depends on your policy and the cause of the damage, so ask your agent before you book. The insurance guide lists the questions to ask.
