Best here is a published score, not an opinion: years in business, review volume, rating and a verifiable website, weighted the same for every company. Ranked from 271 whose own websites we read - warranty, transferability, pier method and financing, side by side. The full table of all 53 that met the bar is below the shortlist.
Fixed weights, applied identically to every company: years in business, review volume, rating, verifiable website. A filled chip means the company states it publicly. No chip means it doesn't say - not that the answer is no.
Bids on the same house routinely differ by a factor of two, and the cheapest is not reliably the worst or the best. The only way to know what your repair should cost is to have more than one company look at it.
Or just call them directly - these are the numbers each company publishes itself. We don't insert tracking numbers, and we aren't paid when you call.
Search by name, town or pier method, or filter to only the companies that publish what matters to you. An em dash means the company doesn't state it - not that the answer is no.

Every company listed here serves inside the outlined area. Most travel further for a large job - the boundary is where they routinely quote, not a hard limit. Where a town shows a number, that is how many listed companies are based there; plenty of towns are covered without having a foundation company headquartered in them.
The Balcones Escarpment runs straight through San Antonio, and it is the single most important thing about foundations here. West and north of it - Helotes, Boerne, Stone Oak - houses sit on thin soil over Edwards limestone. East and south, they sit on deep expansive Blackland clay. Two houses a mile apart can be on completely different ground.
That matters because the correct repair differs on each side. On the limestone side, piers reach rock quickly and the problem is more often a thin, uneven soil layer than deep seasonal movement. On the clay side, piers must go considerably deeper and seasonal swelling behaves much like Dallas. A contractor who quotes the same solution regardless of which side of the escarpment you're on is not reading the site.
San Antonio also sits over the Edwards Aquifer recharge zone, which brings real constraints on excavation and drainage work in parts of Bexar and Comal counties. It is worth asking whether a proposed drainage fix needs a permit before work starts.
The drought cycle here is more severe than in Houston. Long dry summers pull moisture out of clay soils to depths that shallow piers cannot bridge, which is why pier depth - not just pier count - is a question worth asking on any bid east of the escarpment.
San Antonio is steel-dominant like Dallas, but for a different reason. 85% of the 20 companies naming a method install steel. West of the Balcones Escarpment the limestone is shallow, so a driven pier reaches rock quickly and cheaply. Bell-bottom piers - which need depth to work - appear on just 5%, the lowest share of any city here.
Share of the 53 listed companies stating each item on their own website. 11 of the 27 with a known founding year have been in business twenty years or more. Median review count is 36.
Yes, more than almost anything else. Limestone to the west and north, deep expansive clay to the east and south. It changes the correct pier depth and sometimes the correct method entirely. The four methods compared →
Typical perimeter work runs into five figures, and depth drives the price on the clay side of the area. Ask what depth the piers are being taken to, not just how many. What repair actually costs →
Possibly - parts of Bexar and Comal counties sit over the Edwards Aquifer recharge zone, which brings restrictions on excavation and runoff. Ask before work begins.
Usually pier depth and pier type. A quote that reaches bedrock and one that stops short are different jobs, even at the same pier count. What repair actually costs →
We collected every foundation repair company operating in San Antonio from public listings - 271 of them - then opened each company's own website and read it. Seven attributes were recorded, and only what the company states publicly. Nothing here is inferred, estimated, or paid for.
218 were excluded: no working website to verify against, too few reviews to judge fairly, based outside the area, running a network of city-named microsites, or not a foundation company at all - foundation searches surface a lot of roofers and handymen by the second page of results.
