Our Testimonials

"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."

"Thank you for your generous donation of $340.00 toward the locating of the underground utilities on our campus. It will allow our church to further serve our community and our congregation by providing a safer environment in the parking lot with improved lighting. The heart of our church is to serve our community. By supporting us you are also supporting our community. Thank you so much! Thank you again for your generosity and speedy attention to our request"
