Underground Power Done Right.

Underground electrical runs require proper conduit, correct burial depth, and code-compliant wiring sizing for the load and distance. Getting it wrong means failed inspections, fire hazards, or a system that trips constantly.

We handle everything from site evaluation and trenching to conduit installation, wire pulling, termination at both ends, permitting, and inspection coordination.
