Private Utility Locating

Beyond the 811 paint line.

Lone Star 811 stops at the meter. We mark the rest — private power, water, gas, comms, sewer laterals, irrigation, and fiber on your property.

Overview

What you get when you book.

More than 65% of utilities on a typical site are private and unmarked by the public one-call system. Our NULCA-trained locators use electromagnetic induction and ground penetrating radar to trace energized and de-energized lines, follow tracer wire, sonde non-conductive pipe, and verify 811 marks before excavation begins.
