FAQs About our Locating Services
What is underground electrical locating?
Underground locating is the process of identifying and tracing buried electrical wires or cables that may be damaged, severed, or causing power issues. We use specialized equipment to safely detect these faults without invasive digging.
When should I call for underground locating services?
If only part of your home has power, your breakers aren’t tripped, or the utility company says there’s no issue on their end, the problem may be underground. Call us if you suspect damaged wiring or need to confirm where buried lines are before digging.
Can you repair the damaged wire after locating the problem?
Yes. We’re licensed electricians, not just locators. Once we’ve found the source of the issue, we can repair or replace damaged underground wiring and ensure your system is safe and up to code.
Is your locating service the same as utility line marking (like 811)?
No. 811 services mark public utility lines before digging, but they don’t locate privately owned or residential electrical lines beyond the meter. Our service is focused on private power lines and faults affecting your home or business.
What if I’m not sure that my power problem is an underground issue?
You don’t have to be. If your power problem isn’t clearly related to a panel, breaker, or utility issue, give us a call. We’ll start with a full troubleshooting assessment to determine if underground locating is the right step.
