The Short Version
A contractor evaluation documents what a foundation repair company observes and measures, and forms the basis of a repair scope if repair is warranted.
An engineering assessment is performed by a licensed professional engineer, who may issue a report or letter carrying their seal and professional responsibility.
Both are legitimate. They answer different questions and they are appropriate in different circumstances, and confusion between them costs homeowners money in both directions — paying for an engineer when one is not needed, or presenting a contractor’s paperwork where an independent opinion was required.
Side by Side
| Contractor evaluation | Engineering assessment | |
|---|---|---|
| Performed by | Foundation repair company | Licensed professional engineer |
| Output | Findings report and, if warranted, a repair scope | Report or letter, which may carry a seal |
| Authority | The company’s own documented findings | Professional opinion with professional responsibility |
| Orientation | Whether and how a repair would be performed | Structural condition and, sometimes, specification |
| Independence | Performed by a party with a commercial interest in the outcome | Independent of any repair contract |
| Cost | Lower | Higher |
| Typical use | Homeowner starting from an observation | Transactions, disputes, permitting, complex cases |
What Our Evaluation Provides
A foundation evaluation produces a relative elevation survey across the floor plane, visual distress mapping inside and out, a record of site conditions, and — on a raised foundation — a crawl-space assessment.
You receive a written report of findings, and where repair is warranted, a scope covering method, inclusions, exclusions, schedule, warranty, and payment terms. It is non-destructive and typically takes under an hour on site.
What it explicitly does not do: carry a professional engineer’s seal, constitute an independent structural opinion in the formal sense, certify past work performed by others, or produce an engineered specification.
We state those limits in the report rather than leaving them implied.
When an Engineer Is the Right Call
A real estate transaction where a buyer, seller, lender, or agent wants an independent structural opinion. A contractor’s assessment has an obvious commercial interest in finding work; an engineer’s does not.
A dispute. Between neighbours, between buyer and seller, with an insurer, or with a previous contractor. An independent professional opinion carries weight a contractor’s report does not.
A permitting requirement. Some jurisdictions or scopes require an engineered specification for foundation work. Our permits guide covers how requirements vary across Houston-area authorities.
A genuinely uncertain situation. Where the appropriate remedy is not clear, where contractors disagree materially, or where the structure is unusual.
A large decision. A repair-versus-replacement question, or a scope involving substantial cost, is worth an independent view before committing.
When a Contractor Evaluation Is Enough
For most homeowners starting from an observation — a crack appeared, a door started catching — a contractor evaluation is the sensible and proportionate first step.
It costs less, it produces measured findings you keep, and if the conclusion is that no repair is warranted, you have a documented baseline and have spent considerably less than an engineering assessment would have cost.
If the findings turn out to be more complicated than expected, escalating to an engineer from there is straightforward, and the elevation data you already hold is useful input.
Why We Say This
It would be commercially convenient to present our own evaluation as sufficient for every situation. It is not, and telling you otherwise would be misrepresenting what we produce.
Recommending an engineer is not a lost sale. A homeowner who gets the right assessment for their circumstances makes a better decision, and a decision made on the wrong document is a problem for everyone involved later.
If you ask us whether your situation needs an engineer, you will get a straight answer.
Practical Notes
Sequence. Where both are involved, an engineering assessment usually comes first, establishing condition and sometimes specification. Contractors then bid to that specification, which has the useful side effect of making the proposals genuinely comparable.
Who engages the engineer. Where independence matters — a transaction or a dispute — the party wanting the opinion engages them directly rather than going through a contractor.
What to ask for. Be specific about what you need the document to do. A letter confirming a condition is different from a specification for repair, and the engineer needs to know which you are asking for.
In a transaction. Our guide on buying a home with previous foundation work covers which documents matter and when a stamped opinion is the one being asked for.
