Answer five questions and get a plain-English read on urgency. This is an informational screening tool only — it is not a structural assessment, and it does not replace an in-person evaluation.
Every result is a planning estimate, not a quote or an engineering determination. Real pricing depends on soil conditions, access, existing structure, engineering requirements, and your jurisdiction’s current fee schedule. For structural questions we coordinate with a licensed engineer — we do not perform engineering ourselves. Get a site-specific estimate before committing to a budget.
Not every crack is a problem. Concrete shrinks as it cures, and thin vertical cracks in a stem wall are extremely common in Bay Area homes. What changes the picture is direction, width, movement, and what the rest of the house is doing.
Width matters, but movement matters more. A quarter-inch crack that has not changed in fifteen years tells a different story than an eighth-inch crack that opened over one wet winter.
Large parts of Santa Clara County sit on expansive clay. It swells when it gets wet and shrinks when it dries, and that seasonal cycle works on a foundation year after year. Add irrigation right against the house, a downspout dumping at the corner, or a slope that drains toward the building, and you get localized movement that shows up as cracking long before anything dramatic happens.
That is also why drainage is usually the first thing we look at. A surprising number of cracks stop progressing once water is routed away from the foundation. Others need real structural work. Only an in-person look, and in many cases a licensed engineer's evaluation, can tell you which one you have. If it turns out repair is warranted, our foundation repair and retrofit page covers what that work involves.
A simple habit that helps: mark each end of the crack with a pencil line and the date, and take a photo with a coin next to it for scale. Repeat in three months. Documented movement is far more useful to an engineer than a single snapshot, and it costs you nothing.
No. It is an informational screening questionnaire based on five self-reported answers, nothing more. It is not a structural assessment and cannot diagnose a foundation. Any crack that concerns you should be evaluated in person.
A licensed engineer. We are a foundation and concrete contractor, so when a structural determination is needed we coordinate with a licensed engineer rather than making that call ourselves. We handle the construction side once the scope is defined.
Because those patterns are associated with lateral pressure and differential movement rather than simple shrinkage. That does not mean yours is serious, but it does mean the pattern warrants a professional look rather than a wait-and-see approach.
Stable and dry is genuinely reassuring, and many such cracks are cosmetic. Keep documenting it with dated photos. If it starts to move, widen, or take on water, get it looked at.
Because a cost without a diagnosis would be a guess dressed up as a number. Repair pricing depends on cause, extent, access, and soil, none of which a five-question form can establish. We price repair work after an in-person evaluation.
