Drainage and grading
Getting rainwater away from the slab so the clay stops swinging
Lake View is on the north side of San Angelo, one of the city's long-established areas.
Lake View sits on the north side of San Angelo and has been part of the city for a long time. Wherever a house sits in Tom Green County, it is on the same family of clays — so the more useful question on the north side is not what the soil is, but what the water is doing to it. That is the variable you can actually change, and it is where the cheapest fixes in this entire trade live.
Uneven moisture is the mechanism that breaks foundations on clay. Not water in general, unevenness. A downspout discharging at one corner of the house soaks the soil there while the opposite wall bakes dry through the same summer, and that difference is exactly what lifts one part of a foundation while another settles. It is worth understanding because it flips the usual assumption: the problem is often not that the ground is too dry or too wet, but that it is both at once in different places under the same house.
The useful thing about drainage is that you can inspect it yourself, for free, in about ten minutes during the next rain. Walk the outside of the house while it is actually raining and watch where the water goes — the evidence is usually visible as a splash pattern, a worn channel in the soil, or a puddle that sits against the wall long after the rain stops.
The way to settle any of this is measurement rather than opinion. A free evaluation takes relative floor elevations across the house, records where and how the cracking runs, and looks at what the drainage and any nearby trees are doing to the soil — and you get that in writing. Quite often the answer is that the movement is old, stable and needs nothing, which is a perfectly good outcome and costs you nothing to establish.
Where work is needed, the plan should name every pier and its location before anything begins. Texas issues no foundation repair license, so a written scope, insurance confirmed with the insurer, an engineer's involvement, and a warranty in writing are the four things worth asking of anyone.
