MARK IT: Testimonials

Our valued customers are the first to acknowledge our high quality service and attention to detail.

"We have employed One Call Concepts Locating Services as an underground locating contractor since 1995. They have worked diligently toward minimizing underground facility damage in our service territory. It is with admiration that we recommend them to any additional employer."

"From the numerous underground locating service providers that I have had to hire over the years to perform underground marking/location of existing facilities, One Call Concepts Locating Services, Inc. stands above them all in performing high quality underground locating services. OCCLS management staff and field crews perform the work as if they were protecting their own underground facilities. I highly recommend OCCLS."

"One Call Concepts Locating Services has been doing an outstanding job locating lines in Maryland. They have had no mis-locate damages and have been doing a good job on Damage Investigations. The two inspectors we use for the Pipe Type Cable are doing an outstanding job communicating, providing paperwork, taking pictures and arriving at sites in a timely manner. We are very pleased with the performance of OCCLS."
