NDT Jobs & Salaries in Houston, TX
The NDT job market in Houston is shaped directly by its industrial base — Petrochemical refining, Offshore oil and gas, LNG export. Major employers and asset owners in the area include ExxonMobil Baytown Refinery, LyondellBasell Channelview Complex, Port of Houston, all of which run continuous inspection programs and rotate inspection contractors against multi-year MSAs. Code authorities most often cited in local procurement specifications are API 510 / 570 / 653, ASME Section VIII / IX / XI, BSEE for offshore, so any inspector hunting work in Houston should expect those references in interviews and pre-qualification packages. Cost of living and energy-sector premiums push wages noticeably above the U.S. median for inspectors. A recurring local theme: "Turnaround season in Houston compresses every NDT contractor's calibration and certification window — losing a Level II UT tech to an expired cert can cost a six-figure shift." Beyond the top-of-mind names, the deeper bench in Houston includes Valero Houston Refinery (245k bpd), LyondellBasell Channelview, Phillips 66 Sweeny — these are the employers that pre-qualification managers screen most often when filling rotational openings. BLS-anchored Level II wages in Houston run around $84,000/yr; Level III with API endorsements layers on to roughly $128,000/yr — the gap between the two is the single biggest reason local inspectors pursue Level III. Jurisdictional layer matters here: TPSC §757.001 (boiler & PV) and TCEQ Air Permit Rules 30 TAC Ch. 116 apply on top of the federal/national codes, and missing the local-authority reference on a procedure submission is a common rejection reason for first-time-into-Houston contractors. One angle that differentiates Houston from peer markets: Largest concentration of API 510/570/653 inspectors in North America (~5,000+). Turnaround calendar: Spring TAR (Feb-May); Fall TAR (Sep-Nov) — the inspection workforce flexes hard against this rhythm and overtime stacks during those windows.
