Texas does not license this trade. No state license, no statewide general contractor license - which means the filtering a license would normally do has to be done by you. Here is what to look at.
Start here: Texas does not license foundation repair contractors. There is no state license for this trade, and no statewide general contractor license either. Anyone can do this work.
This is not a scandal and it does not mean Texas foundation contractors are bad - most of the 333 companies in this directory are long-established businesses with hundreds of reviews. It does mean the filtering that a license would normally do for you has to be done by you.
63% of companies here advertise a free inspection, and it is the industry norm nationally. It is also a sales visit. NerdWallet puts the conflict plainly: contractor inspections are typically free, and contractors "may have financial incentive to overstate problems."
A licensed Texas home inspector lists the specific behaviors worth ending the visit over (Super Inspector):
A separate consumer-warning piece adds demands for full payment in cash up front, and "contractors" who take a deposit and never return.
A claim that "90% of foundation repairs in North Texas are unnecessary" circulates widely and appears on otherwise credible sites. We traced it and found no study, survey or engineering-board data behind it - it appears to originate with a single author and to have been reprinted between a small cluster of related sites. It may well be directionally true. It is not a fact, so we are not going to print it as one.
The most important structural question in the whole process - how many piers, and where - is usually answered by the company that gets paid per pier.
An independent DFW engineering firm notes that a contractor's engineer "is often hired to approve the contractor's proposed work," and recommends engaging one who follows 2022 ASCE Level B evaluation standards and is independent of any repair company (Thomas Engineering Consultants).
14% of the companies listed here state that they work from an engineer's report. Ask the rest - and ask specifically whether the engineer works for you or for them.
All 333 companies here cleared a basic bar: a working website, enough reviews to judge, and a real presence in the area.
