Is This The Right Underground Electrical Service For You?

Underground Electrical Service is ideal for powering remote buildings like barns, sheds, and backyard offices. We also replace damaged underground lines and install service for new construction. Not sure if underground wiring is right for your project? Contact Us and we’ll guide you to the right service!

Can I run underground wire myself?

Not legally in most cases. Underground service replacement must follow strict codes and be inspected — we’re licensed and handle it all for you.

Do I need a permit to replace my service line?

Yes — and we’ll secure it and schedule any inspections so your project stays on track.

What kind of wire is used for underground installations?

THWN-2 or UF-rated wire in conduit, depending on your soil and depth — we’ll assess what’s best.

How deep does the trench need to be?

Depth depends on conduit type and local codes, but it’s usually 18–24 inches or deeper for high-capacity lines.

What is underground electrical service replacement?

Underground electrical service replacement involves removing and replacing buried power lines that connect your home or building to the utility grid. This process ensures safe, reliable power when existing underground wiring is outdated, damaged, or no longer up to code.

How do I know if I need to replace my underground electrical service?

Common signs include flickering lights, frequent breaker trips, power loss to parts of the property, or visible damage during yard work or inspections. If your underground lines are over 30 years old or were installed with outdated materials, it’s smart to have them inspected by a licensed electrician.

Cody was our electrician, and he did a phenomenal job. He was kind, patient, and incredibly knowledgeable throughout the process. His attention to detail was exceptional—he even took the time to clean fingerprints off the chandelier after installing it. Cody is by far the best licensed electrician we’ve ever hired, and we wouldn’t hesitate to recommend him.

Very impressed with Logo Electrical! Called them, quick response and someone came out that day! Cody was great! Not only did he complete the project, he was also very instrumental in my decision process regarding the overall layout of my new garage shop lights, which I was needless to say very happy with! I would also say they are reasonable on pricing and deliver a professional experience. I will definitely use them for future projects and would highly recommend them!
