    Customer Feedback

    We enjoy listening to feedback from our clients

    “I called in for a basic scan of concrete to identify power in the slab.  Before they left site, they had put a camera down the drain, confirmed the exact location & depth of my tie in spot, radio scanned for high voltage conduits & performed a GPR scan to identify any additional obstructions that the radio scan was unable to see.  From the variety of tools on every truck, to the experience of their scanners, this company is in a league of their own”

    I recently hired Complete Locating Services Inc. for private utility locates on a commercial project in the Brantford area, and I couldn't be more impressed. Their team arrived on time, equipped with top-notch tools like GPR and sewer cameras, and pinpointed every underground line with incredible accuracy—no surprises or delays during excavation. The process was seamless, efficient, and cost effective. Professional from start to finish, with clear communication and a focus on safety.
