What These Services Cover
Electromagnetic Locating
Electromagnetic locating is typically used for conductive utilities that can be traced by direct connection to the line or inducing the line, such as certain electric, tracer wire, communication, and other metallic lines. This is often the most efficient option when a line is traceable and accessible.
Ground Penetrating Radar (GPR)
GPR is used when utilities may be non-conductive, difficult to trace, buried in congested areas, or when additional subsurface information is needed. GPR is commonly requested for private utility locating on residential, commercial, and developed properties where buried lines may not be marked through an 811 request.
Sewer Sonde and Camera Locating
Sewer sonde and camera locating is often used to trace sewer laterals and identify their route from a building toward the connection point. This can be helpful before excavation, repairs, septic-related work, or property improvements.
Magnetic Locating
Magnetic locating can help identify certain buried metallic objects and features where standard tracing methods are not the best fit. Often used to find property pins, survey markers, buried lids.
How Pricing Typically Works
Most private utility locating jobs are priced based on the locating method needed, the time required onsite, and travel time to the property. Some jobs can be completed with standard electromagnetic locating, while others require GPR because of site conditions, utility type, congestion, depth, or a lack of accessible tracing points.
In many cases, homeowners only need a focused locate for a fence line, sewer lateral, water service, electrical feed, irrigation line area, or another specific work zone. Larger properties, more complex commercial sites, and projects requiring multiple locating methods may require additional onsite time.
Why Private Utility Locate Pricing Can Vary
Property Size and Layout
Larger properties, longer utility runs, and areas with multiple structures or additions can increase the time required for a thorough locate.
Utility Type
Traceable conductive utilities are often more straightforward than non-conductive or difficult-to-access lines. Jobs involving PVC, unknown routes, or heavily developed sites may require GPR or a combination of methods.
Site Conditions
Concrete, gravel, landscaping, fencing, limited access, traffic areas, older infrastructure, and congested underground conditions can all affect the time needed onsite. So does the multiple runs to eliminate false positives.

Private Utility Locating vs. 811
A common reason customers visit this page is to understand the cost of private utility locating compared with calling 811. In many cases, 811 locate requests cover public utilities only and stop at the meter, transformer, or main service connection. Private lines on private property often require a separate locate before digging begins.
That means a homeowner or contractor may still need private utility locating for water lines, sewer laterals, power to detached structures, irrigation systems, outdoor lighting, communication lines, and similar underground utilities.
