Delaware's trusted provider of professional private utility locating services. Finding what 811 won't since 2015.
Millsboro Utility Locating Services was founded to address a critical gap in the construction and excavation industry: the need for reliable private utility locating that goes beyond what 811 provides.
While 811 does an excellent job marking public utility lines, homeowners, contractors, and developers are left on their own when it comes to private utilities—the lines that run from the meter to your property, including electric to sheds, irrigation systems, septic lines, and more.
