What to Expect From a Houston Foundation Evaluation

The visit has four parts and usually takes under an hour for a standard home. First, we listen: what you have noticed, when it started, whether it has changed, and whether anything else has happened at the property such as plumbing work, a new tree, irrigation changes, or a previous repair. That history matters, because a crack that appeared last month reads differently from one that has been stable for a decade. Second, we run a relative elevation survey. A level reference is established and floor height is recorded at points across the accessible living area, producing a picture of the floor plane relative to a benchmark datum. This is the measured part of the visit and it is what everything else is weighed against. Third, we map the visible distress inside and out: crack locations and orientations, separations at door and window corners, gaps at baseboards and trim, brick and mortar cracking, frieze board separation, and door and window operation. Location and pattern carry the information, not crack width alone. Fourth, we record site conditions: perimeter grade, where downspouts discharge, standing-water evidence, irrigation coverage, tree species and proximity, and the foundation type. Afterward you receive a written report of the findings, the scope if repair is warranted, and a plain statement of what the visit could not establish.

They are different things with different authority and they answer different questions. A contractor evaluation, which is what we provide, documents what we observe and measure and forms the basis of a repair scope if repair is warranted. It is performed by people who install foundation repairs, and it is oriented toward whether and how a repair would be carried out. It does not carry a professional engineer's seal and it is not an independent opinion in the formal sense. An engineering assessment is performed by a licensed professional engineer, who may issue a stamped report or affidavit, often following guidance published by groups such as the Foundation Performance Association (FPA), a Houston-based technical association focused on foundation and geotechnical practice in the region. That carries a different weight and is specifically what certain circumstances call for: a real estate transaction where a buyer, seller, or lender wants an independent structural opinion; a dispute between parties; a permitting authority that requires an engineer's specification; or a complex situation where the appropriate remedy is genuinely uncertain. It generally costs more and produces a document rather than a proposal. For most homeowners starting from an observation, a contractor evaluation is the sensible first step, and it costs less. We will tell you when your situation is one that calls for an engineer instead of, or as well as, our visit, and we do not treat that as a lost sale.

Yes, and we write it down. A conclusion that no repair is warranted is a legitimate output of an evaluation, and it is a common one. If the elevation survey shows a floor plane within a normal range and the visible distress is consistent with cosmetic or seasonal causes, the report says to monitor rather than recommending work. That report includes what to watch, how to document it — dated photographs from consistent positions, noting crack locations and any change in door operation — and when to re-measure, usually after the next significant seasonal swing. The re-measurement is where the baseline pays off, because comparing two surveys taken months apart tells you whether something is progressing or simply cycling with the weather. That comparison is far more informative than any single visit. Houston clay moves seasonally, and distress that opens in a dry summer and partly closes after a wet autumn is behaving differently from distress that only ever gets worse.

The on-site visit is typically under an hour for a standard single-storey home. Larger homes, multi-storey layouts, homes with restricted access, and raised foundations needing a crawl-space assessment take longer. We respond to requests within 24 hours to discuss the property and arrange a time. You do not need to move furniture or prepare anything in particular, though clear access to floors, the exterior perimeter, and the crawl-space opening on a raised home all help.

It is much better if you are, at least for the start and the end. The walkthrough at the beginning is where you tell us what you have noticed and what the history is, and that context genuinely changes how we read the findings. At the end, we walk through what the readings show while we are still standing in the house, which is easier to follow than reading it later. If you cannot be present for the whole visit, being there for those two conversations is the part that matters.

No. The evaluation uses non-destructive methods. We do not core the slab, break floors, excavate, or open walls. Floor elevation is measured with a level reference, distress is recorded visually and photographically, and site conditions are observed. On a raised foundation, the crawl-space assessment uses the existing access opening. Nothing is disturbed and nothing needs repairing afterward.

It happens, and the evaluation often surfaces it. A wet patch, a warm spot on the floor, unexplained water usage, or damp soil in one zone can all point toward an under-slab plumbing issue rather than soil-moisture-driven movement. A plumbing slab leak and a structural foundation problem are different issues requiring different assessments, and they sometimes occur together. Where leak symptoms dominate, we usually recommend a plumbing assessment first, because ruling a leak in or out changes what the structural picture means. Piering a slab while a line is still leaking underneath addresses the effect and leaves the cause running.

Yes, and it is a common request. For a property with visible distress or a known repair history, an evaluation gives you measured findings before you commit. Be aware of the scope limits: our evaluation documents what we observe and measure. It is not an engineering assessment, and it will not certify past work performed by someone else. For a transaction where an independent structural opinion is wanted, or where a lender or party specifically asks for one, a professional engineer's report is what fits. Our guide on buying a home with previous foundation work covers which documents to request from the seller.

No, and we will not pretend otherwise. Photographs show you what a crack looks like. They cannot show floor elevation, distress pattern across the structure, site conditions, or history. Diagnosing a foundation from a photo is guesswork dressed up as expertise. Photos are useful — send them, they help us understand what you are describing and prepare for the visit — but they inform the conversation rather than replacing the measurement.

A written report of the findings: the elevation readings, the distress mapping, the site conditions recorded, and the conclusion those support. If repair is warranted, a scope follows, covering method, inclusions, exclusions, schedule, warranty, and payment terms. If it is not warranted, the report says so with a monitoring recommendation. Either way the document is yours to keep, to show to another contractor, or to use as a baseline for re-measurement later.

Very little, but a few things help. Clear access along the exterior perimeter where you can. Make sure the crawl-space access is reachable on a raised home. Gather any documents you have: a previous evaluation, a prior repair invoice, a warranty, an engineer's letter, or another contractor's proposal. And make a short list of what you have noticed and when, because in the moment it is easy to forget the door that started catching last spring.

They are context, not findings. Regional land subsidence is measured and published by USGS and the Harris-Galveston and Fort Bend Subsidence Districts, and published fault mapping shows approximate traces at a regional scale. Both are real. Neither establishes the condition of one house, and no map can substitute for measuring the property. We will explain what those sources report and what they cannot tell you, and then we will measure your floor.
