"CNI locates has always gone above and beyond to meet my needs. In this industry scheduling doesn`t always go as planned and they still seem to get me taken care of. Their pricing has always been far more reasonable then other company`s which leads to better margins on my projects. I would gladly recommend them to anyone needing these services."

Brian Bertrand

"I've been a residential service plumber for over 20 years and have used several locating companies over that time. These guys are my new go to location company. They were fast, friendly, easy to schedule and work with, and way less than the other guys! Thank you CNI Locates!"

"C&I Locates is a professional and courtious locating company and will continue to use them for all of my private locating needs! Thanks, Eric Holmgren, Manager Potelco Inc. 253-606-2544"

Eric Holmgren

"CNI Locates had a great website that helped inform me about their services before calling them. They were able to answer all my questions on the phone. They told me that they could schedule me for the next day within 24 notice Monday through Friday, for their standard services. They provided me their service rates and field office locations they bill from and back to (Tacoma, Renton, Seattle, and Everett). After scheduling the appointment, the technician called me in route to my house to give me an estimated time of arrival. When the technician was finished he personally showed me everything that he found and passed along any limitations/concerns that he had. It turns out that we had a buried plastic conduit, that we didn't know about. CNI was able to insert the line to see where it went. Now we are able to use that empty conduit to run irrigation under our driveway. The technician was very honest and helpful. I would highly recommend them to any one looking for leak detection, metallic line detection, non metallic pipe detection, video camera pipe inspections, utility mapping and design surveys, electrical ground fault detection, concrete and structural imaging, ground penetrating radar, and magnetic detection."

Lisa Williams

"I have been working with this company for around three years. During my time with this company I have really come to love the levels of professionalism and dedication that is present at every level from field techs, to management, all the way up the chain right to the ownership. Having worked in many fields in my life, I have never seen the level of cooperative involvement that is now present now within my daily life. Everyone is here to make sure that everyone else succeeds. My opinions and ideas matter to the management staff. All of my scheduling needs have been met giving me an excellent work/life balance. All of my teammates exude amazing levels of professionalism and expertise. Working here makes it easy to come in to work, instead of dreading another work day. The work itself is never dull or monotonous, as every day brings a new puzzle to uncover and a new challenge to overcome. I say this with all honesty, this is the greatest opportunity that I have ever found within my field. I am both thankful and grateful for every chance offered to me as I have excelled within my position here with the company. Thank you CNI. Every single one of you guys and gals absolutely rock!! I would give you six stars if able."

Michael Rosenthal

"We used them to locate some water lines at our church so we could safely dig for some new retaining walls. Not only did they find the locations of all of the lines we knew we needed to know about, they found another buried line we were completely unaware of, and that could have been a major problem. They were super helpful, and gave us some very good information up front, including the limitations of the ground penetrating radar and a simple-but-effective technique for locating a plastic water line, if we had needed to do either of those things. Fortunately, in our case, we had all metal water lines (one copper, one galvanized steel), so they were quite easy to locate without any problems. if you need to locate a water line or other buried utility line between your meter and your house, I would strongly recommend using them to find it before you dig, in addition to the normal "call before you dig" utility locates that you are required by law to do. It's well worth the money - hitting a water line or other buried utility when digging can get very expensive to repair, very quickly. Their basic locating cost is not that expensive, and they are very up front with details and ways to save money all while getting you the best possible location data once they are onsite."

"Brandon and Benny were great at finding my leak in my 350+ ft of water line service. It was a difficult leak because it was so long. They both were very personable and they cared about my dilema, out of water, Thank you so much"

"CNI Locates came out to locate my construction site within 24 hours of my online request. Their technician went over all the service applications with me during the process. This is the only good experience I’ve had with an utility locating company and I wouldn’t use anyone else!"

Tyler Evans

"I would like to thank you and your staff for the recent locating service you provided to the First Pentecostal Church on February 7th. It was in support of an electrical project and we were able to successfully dig a trench across 3 major utilities. Everything was extremely accurately marked and there were no surprises. I spoke to Benny on the phone and he was very kind and pleasant to work with. And I met Kevin onsite and he did a very nice job. Your company offered us a very generous discount making the entire service free of charge. We greatly thank you for this. God bless."

Aaron Mercado

"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."
