At a glance
In Texas, a licensed professional engineer may evaluate a foundation problem and design a repair. An engineer you hire before signing with a repair company owes professional duties to you and can give bidders the same plan to price if repair is needed. Posted evaluation fees from Texas firms in our sample run from about $400 to $1,000; ask for a local quote. Request an elevation survey and written report, check the engineer's license on the state board's roster, and keep the post-repair records. San Antonio and Round Rock require an engineer for every residential foundation repair permit. Austin's rules depend on the work and the house.
What an engineer assesses
A licensed Texas professional engineer can analyze a foundation problem and design an engineered repair. The state engineering board says an expert opinion on the cause or a recommended repair is engineering work. Texas law has conditional exemptions for private-dwelling repair and plans, so a PE is not required for every repair. A home inspector licensed by the Texas Real Estate Commission must report on how a foundation is performing, but is not required to find the cause or recommend a fix.
That matters because cracks and sticking doors can come from causes other than foundation movement, and all foundations move a little, even good ones. Texas has no state foundation repair contractor license. A PE license gives you a state roster and professional rules for the engineering work.
Who the engineer works for
Board rules require a Texas engineer to act as a faithful agent for the client, the party that hired them. An engineer must disclose a potential conflict of interest in writing, and may not take pay from more than one party for the same project. The Texas foundation guidelines call avoiding conflicts of interest essential to a credible evaluation.
The Texas rules we reviewed do not say the homeowner must hire the engineer directly. An engineer you hire answers to you. Ask any engineer who hired them, who pays them, and whether they have any tie to the company that will do the work.
What to ask for
The Texas Section of the American Society of Civil Engineers sets out three levels of evaluation in its guidelines for residential foundations (Version 3, 2022). The guidelines are voluntary; they were written in part to guide the state engineering board when it reviews complaints.
| Level | What the engineer does | When it may fit (our suggestion) |
|---|---|---|
| A: first impressions | Interviews you, reviews drawings, soil reports and past repairs, walks the house, and on request writes a report of first impressions | A quick opinion on whether to worry |
| B: elevation survey | Adds a survey of relative floor elevations drawn to scale, and reports deflection and tilt against accepted limits | Before any pier plan: piers should rest on measured elevations |
| C: added testing | Adds testing the engineer judges useful, such as soil samples, plumbing tests, steel or cable checks, a tree survey and a mapped survey of cracks | Unclear causes, plumbing leaks, disputes |
The state board has disciplined an engineer who recommended piers without taking elevation measurements. If a repair is needed, the plan should show where each pier goes and its size, depth and material. Expect the guidelines' plain warnings in the documents: piers under part of a house do not help the rest, and lifting rarely makes a foundation level. After lifting, the water and sewer lines should be tested for leaks.
How to check an engineer
- The license. Search the engineer's name or license number on the Texas Board of Professional Engineers and Land Surveyors PE roster. It shows license status and expiry. A license expired for two years or more drops off the roster, so a missing name is not proof either way.
- The firm. An engineering firm must be registered with the board. On the firm roster, only Active means the registration is current.
- The seal. A sealed plan or report shows the engineer's name and license number. A seal means the named engineer did or directly supervised the work and takes responsibility for it. It does not prove a site visit: the board has disciplined an engineer who sealed letters about piers an employee inspected.
- The record. The board publishes disciplinary actions, except informal reprimands. To ask whether complaints were ever filed, contact the board.
- Insurance. Texas does not require engineers or engineering firms to carry liability insurance. Ask.
What Texas cities require
Whether an engineer is involved at all depends partly on the city.
| City | Engineer required? | What the city asks for |
|---|---|---|
| San Antonio | Yes, every repair | An engineer-of-record letter, signed and sealed, with the application, and the engineer's inspection letter to clear the foundation inspection |
| Round Rock | Yes, every repair | An engineer-of-record letter and a sealed engineered foundation plan with the application, and a final engineered report before the final inspection |
| Austin | Depends on the work | Foundation repairs may use an express permit; repairs of 128 square feet or less are exempt from a building permit. Verifying an existing structure at least 10 years old is exempt from structural drawings, but the inspector may request drawings or a Structural Verification Report from a Texas-registered engineer or architect. New foundation or framing work has different rules. |
In San Antonio the repair company is usually the one that applies for the permit. Hiring your own engineer is still open to you.
What to keep after the repair
- The engineer's report and repair plan.
- The post-repair elevation survey. The guidelines say the engineer or a representative should measure again after the repair and give you a copy.
- The engineer's letter of substantial completion, if you hired the engineer to write one. It is an opinion that the work generally follows the plan, not a guarantee.
- The permit and its final inspection. In Austin, copies of a closed permit's documents come through a public records request.
- Plumbing test results, and the warranty with its transfer terms. Transfer rules vary by company: some require notice within 30 days of a sale, a notarized form or a fee.
These papers answer the questions a buyer will ask when you sell. The Texas seller's disclosure form asks about previous structural repairs and about repairs made without required permits.
