Underground Electric Line Installation
Trenchless electrical conduit and direct-bury cable for reliable, weather-resistant power. Residential, commercial, and service upgrades.
Sloan Underground Construction has been burying electric service across the Carolinas since 1965. We bore underground conduit and direct-bury cable for new homes, service upgrades, overhead-to-underground conversions, detached buildings, and commercial feeds. Residential runs typically cost $2,000–$6,000 and finish in 1–2 days, coordinated with your licensed electrician.
How much does underground electric line installation cost?
Residential underground service runs $2,000–$6,000 depending on length and amperage. Longer runs to detached buildings, new construction service, or larger-conductor commercial feeds scale to $6,000–$25,000+. We coordinate with your licensed electrician on termination, panel, and inspections — our scope is the bore and conduit placement.
Why Property Owners Convert Overhead to Underground
Overhead service looks cheap until the first ice storm brings a limb down on the line. Underground electric eliminates wind, tree, and weather damage and replaces a visible overhead run with a clean, concealed path from the pole or transformer to the service panel. Insurance carriers and resale markets both reward it.
We install conduit and pull cable for new builds, additions, service upgrades, detached garages and workshops, farm buildings, and pool equipment rooms. On commercial and municipal projects, we run larger-diameter PVC or HDPE conduit for 200A–800A feeds and coordinate with the electrical contractor on sleeving and pull tension.

How much does underground electric installation cost?
Residential underground service lines $2,000–$6,000 depending on length and amperage. Longer runs, detached buildings, and commercial feeds scale to $6,000–$25,000+. Our scope is the bore and conduit; your licensed electrician handles termination and inspection.
Can you replace my overhead line with underground?
Yes. We bore the underground path from the pole or transformer to the service panel, install the conduit, and coordinate the cutover with your electrician and utility. Going underground eliminates weather, tree, and ice damage risk.
Do you work with electricians?
Yes — we regularly partner with licensed electrical contractors on new construction and service upgrades. We handle the bore and conduit placement; the electrician handles conductor pull, termination, panel work, and inspection.
What conduit do you install?
Schedule 40 or Schedule 80 PVC is typical for residential service. Larger-diameter PVC or HDPE for commercial feeds. Size depends on the conductor and amperage the electrician is running.
