Why the free inspection is not free

A free inspection gives the contractor a reason to turn any minor crack into a repair, because the visit is free and the piers are not.

The incentive

The inspector's employer is paid by the repair, not the diagnosis. As one OKC homeowner put it: "most foundation companies will want to pier even if it isn't necessary."

The documented case

2 companies told one OKC owner the house was "sinking rapidly." An independent engineer billed 1.5 hours; the recommended fix cost about $500 total.

The rule

The engineers' evaluation standard puts it in one line: avoiding conflicts of interest is essential to the credibility of the evaluation. A company that sells the repair cannot meet that rule while diagnosing the need for it.

What a second opinion is worth

The same conflict runs the other way. When the person looking at your house does not profit from the repair, when you get a second set of eyes, or when the company that comes out is straight about what you do not need, the number can fall from five figures to almost nothing. Here are OKC homeowners describing exactly that, in their own words.

A $40,000 quote, then nothing

One homeowner was told by another company she needed more than $40,000 of repairs. The inspector she went to next found no signs of foundation issues at all.

$20,000, or a couple hundred

Another weighed a competitor's $20,000-plus quote against the couple hundred dollars the actual fix turned out to need. Her own summary said it best.

Pointed to an engineer, not a contract

A third credits the rep who came out with recommending an independent engineer and saving the family money, while competitors quoted as much as $30,000.

Steered away from extra piers

Sometimes the honest read comes from the company that shows up. One homeowner credits the estimator who came out with saving them from more piers than they needed, at a competitive price.

Told it was not the foundation

Another was told the wall cracks were not foundation-related at all, and only the garage actually needed piers.

No hard sell

A third had the foundation checked, was told it was in good shape, and got no hard sell on work they did not need.

The pattern is the point. The cheapest way to learn how much work your house actually needs is an opinion from someone who does not sell the work: the $200 - $500 engineer's report above, or simply a second quote before anyone starts counting piers. These are individual homeowner accounts, in their own words, and each links to the original.

What a real engineer's report contains

We have one on file: a 5-page structural report from an Edmond structural engineer (Aug 2023, a pre-purchase evaluation, about $200 - $400 of work). It contains a visual evaluation method, per-defect observations with measurements, a stamped foundation plan marking where piers would go, and repair recommendations. What it does not contain is a repair upsell.

"Metro Engineering, LLC does not participate or oversee repair work recommended in this report."
Verbatim, from the firm's own stamped report.
If repair is needed

A real repair plan is a sealed document with 12 required elements, including its purpose and limitations, the geotechnical information and its source, construction details, and a required post-repair floor elevation survey. Hold any contractor's "plan" against that list.

For big repairs

Major work should rest on a site-specific soil boring and testing program, not just local practice. On completion, an engineer who stays retained issues a letter of substantial completion: the paper trail a future buyer's inspector wants to see.

The 3 levels of investigation: ask which one you are getting

A
Level A

Interview, document review, and a visual walk-through. The standard calls it a report of first impressions, and requires the report to say so.

B
Level B

Level A plus a floor elevation survey: a scaled drawing, with deflection and tilt reported against the published tolerances. Actual measurements.

C
Level C

Level B plus soil sampling, plumbing testing, material testing, and detailed reporting.

◆ The rule worth printing

A Level A report must identify itself as one. Reviewing someone else's report without a site visit is consultation, not investigation; the engineer should personally visit and be in responsible charge. A "free inspection" is, at best, an undeclared Level A with no written report.

The yardstick is public

2 independent engineering bodies publish the same performance limits. A free inspection's yardstick is whatever the salesperson says it is.

Recommended performance limits for residential foundations.
Performance limitASCE Texas SectionFoundation Performance Association
DeflectionL/360 over the foundation, by analogy to the building codeL/360 over a minimum effective length of 20 ft
Tilt1 percent (usually noticeable above that)1 percent over the full length, width, or diagonal

Numbers alone do not condemn a foundation. Below L/360 with no visible symptoms, the foundation is unlikely to be materially deflected; above it with symptoms, excessive deflection is a justified conclusion; above it without symptoms, more information is needed. Floor readings over less than about 20 feet are unreliable, most slabs are built within about 1 inch of level, and without baseline elevations movement can only be inferred, never proven.

Independent structural engineers serving OKC

Engineers who write the report and do not sell the repair. Each listing goes live only after the firm confirms its consent and that it currently takes homeowner work.

◆ Named listings are coming

We are adding independent OKC structural engineers here as each one confirms it takes homeowner work and agrees to be listed. Until then, the test is what matters: an engineer who writes the report and does not sell the repair. Fees OKC homeowners report run $200 - $500 per report (one local receipt: about $200 inspection plus a $200 detailed report, Oct 2024 ), and the community word is that homeowners seek these firms out for unbiased reports. To find one yourself, ask a firm directly whether it also performs repairs, you want one that does not, and use our guide to verifying any foundation company.

Fees homeowners report across firms: $200 - $500 per report. The Foundation Performance Association's own bottom line is to always consult a professional engineer on foundation and drainage issues. Disclosure: if we ever have a referral relationship with an engineering firm listed here, it is named on this page.

Q · How much does a home foundation inspection cost in Oklahoma City?

A repair company's inspection costs $0 and is paid for by the repair it finds. An independent structural engineer's inspection and report runs $200 - $500 in OKC, is measured against the published standards above, and is yours to hand to any contractor you like. Fees: OKC homeowner reports plus a metro firm's fee, 2015 - 2024.

FAQ

Structural engineer vs home inspector: what is the difference?

They do different jobs. A home inspector gives your whole house a broad, visual once-over, usually at a sale, and Oklahoma's own rules are clear about the limit: a licensed inspector is not required to perform engineering services, to judge the adequacy of any structural system, or to predict future failure (Oklahoma Administrative Code 158:70-1-3). So a good inspector who sees a foundation concern notes it and sends you to a specialist. That specialist is a licensed structural engineer, who measures the movement, finds the cause, checks it against published standards, and stamps a report you can repair from. For a foundation question, the engineer's report is the one that answers it.

Is a free foundation inspection really free?

The visit is free. The advice is not, because the person giving it is paid when you buy the repair. That is why the engineers' own standard says an evaluator has to be free of conflicts of interest: a company cannot sell you piers and tell you whether you need them. An independent engineer's report costs $200 - $500 in OKC and belongs to you.

Which investigation level do I need?

Level A is a visual walk-through and document review (first impressions, in writing); Level B adds a floor elevation survey with measured deflection and tilt; Level C adds soil, plumbing, and material testing. Most homeowners start at A or B. For major repairs the standard wants site-specific soil borings, which is Level C territory.

Do I need an engineer for a hairline crack?

Usually not. Hairline cracks are within the published age norms for a house under 10 years old, and cracks up to 1/8 inch for one over 10. The trigger is change: a new crack that keeps widening, or cracks clustering with binding doors. Then get an engineer before anyone patches it, because patching destroys the diagnostic evidence. The warning-signs guide walks through the lookalikes.
