What to Expect From a Foundation Inspection

Before the appointment, ask for one sentence describing the job. Is the person giving a general home-inspection opinion, an engineering evaluation, or a repair proposal? Those are different products even when each includes a walk around the same slab.

That distinction prevents a common disappointment: expecting a visual inspection to produce an engineering design, or treating a repair estimate as though it were an independent diagnosis. A good report should make its scope visible. If the scope is unclear before the visit, ask what will be inspected, what will be measured, whether a written report is included, and what questions the report is intended to answer.

A foundation evaluation starts with the house and the site, not a single crack. The evaluator may ask when changes appeared, whether repairs or plumbing work were done before, and whether symptoms change with the season. Drawings, prior reports, repair records, photographs, and earlier elevation surveys can add a history that the present visit cannot recreate.

For a Texas real estate inspection, the state rules require a written opinion about foundation performance and require the inspector to report the foundation type and the present, visible indications used for an adverse-performance opinion. The examples include binding or non-latching doors, separations, sloping floors, cracks, and distorted masonry. The same rules also address observable grading, gutter, downspout, and crawl-space conditions. The TREC Standards of Practice list those minimum duties and the limits of the inspection[1].

The list is evidence to consider, not a checklist where one marked box proves failure. TREC's own guidance tells inspectors to form the opinion from present and visible indicators and the factors that affect stability, while accounting for age and ordinary use. Its foundation-performance guide also distinguishes ordinary movement from differential movement and describes the visual basis of the opinion[2].

Some visits include relative floor elevations, and some do not. Texas does not require a real estate inspector to use elevation-determination equipment for the minimum home inspection. An inspector may offer a higher level of service when competent to do so, but that extra work should be identified rather than assumed.

An engineering evaluation can also vary in depth. Texas ASCE's voluntary guidance describes a first-impressions level built around history, documents, a walk-through, and site factors; a more detailed level adds relative elevations and a scaled drawing; and a still deeper level can add testing selected for the problem. The guideline says the client and engineer should agree on the scope and the engineer should recommend a level suited to the objective[3].

A longer tool list does not automatically make a conclusion better. The question is whether the observations and measurements fit the assignment, were gathered competently, and are explained with their limits.

Put the useful history in one place before the evaluator arrives:

• Previous foundation, engineering, plumbing, or home-inspection reports.
• Repair plans, warranties, invoices, and dates of earlier work.
• Photographs that show when a crack, gap, or door problem changed.
• Any original or earlier elevation survey, including the point locations if shown.
• A short timeline of leaks, drainage changes, tree removal, additions, or remodeling.

Do not hide a repaired crack or recently adjusted door because it looks minor. A cosmetic repair can remove a clue from the present-day walk-through, while the date and photograph preserve it as part of the history.

A useful report tells you what was inspected, what could not be inspected, what information was reviewed, and how the conclusion follows from the observations. If measurements were taken, look for the reference point, the locations, the units, and any treatment of different floor coverings or built-in slopes. If further testing is recommended, the report should connect that recommendation to a question the first visit could not answer.

The report should also separate observation from conclusion. A diagonal drywall crack is an observation. A statement about foundation performance is a conclusion drawn from the body of evidence. Keeping those two parts visible makes a report easier to compare with a later opinion and easier to revisit if the house changes.
