Our Testimonials

"CNI came out promptly and accurately found the broken underground wire. The locator worker was knowledgeable, polite, and professional. He showed me how the locator worked, which was helpful and nice of him. The price was okay for the trouble it saved us. I am so happy I called them. I would hire them again and highly recommend their services. "

Joann Nelson

"I’m a property manager in the Eastside area and one of my properties, had a suspected water leak. I called CNI Locates, they responded right away and was transparent about all my options and costs available. I was able to have a technician over the following day. The technician called ahead, was on time, and super friendly. We were able to locate the water leak and I was able to have someone out to dig it up and fix that week. Would definitely recommend these guys! "

Ivaylo Draganov

"I want to express my gratitude and satisfaction for a job well done! I called your company in a quandary about how to get a leak in my meter-to-building waterline repaired. I was kindly greeted on the telephone by Larry, who went well out of his way to find the service I needed. He made a number of calls on my behalf and promptly called me back to keep me informed. The on-site locating work was performed by Tim, who was very gracious and supportive and provided insights from his experience that proved very helpful in solving my problem. I am very satisfied and grateful for the assistance and service provided by your company and it’s employees."
