Underground Wiring & Trenching in New Orleans & Metairie

When you're adding power to an outdoor structure, pool equipment, detached garage, or even landscape lighting, running wires overhead isn’t always the best—or safest—option. Underground wiring offers a cleaner look, better protection, and less maintenance over time. But to do it right, it takes more than a shovel and a spool of cable.

We specialize in underground wiring and trenching for homes across New Orleans and Metairie. From Lakeview to Old Metairie and all the way out to Harahan, we install outdoor electrical systems that are safe, code-compliant, and built to last.

Why Go Underground?

Running power underground isn’t just about looks—it’s about longevity and safety. Exposed wires are vulnerable to weather, UV damage, and accidental contact. Underground conduit protects your wiring from all of that, while keeping your yard and outdoor areas clear.

Homeowners in areas like Broadmoor, Gentilly, and Metairie Terrace often choose underground wiring when adding things like:

  • Detached garage or shed power

  • Pool pump and heater connections

  • Electric gates or driveway lighting

  • EV charger installations far from the main panel

  • Landscape lighting or outdoor kitchens

We’ll help you figure out the best route and method based on your home’s layout, electrical load needs, and soil conditions.

Trenching the Right Way

Trenching in New Orleans and Metairie isn’t like digging in dry, rocky terrain. With our local soil—often sandy, silty, and prone to holding moisture—you need someone who understands how to dig safely, avoid utility lines, and backfill in a way that won’t create future headaches.

We handle all trenching in-house, which means no delays waiting on a third party. We dig to the proper code-specified depth (typically 18–24 inches depending on the wiring type), install rigid or flexible conduit, pull the correct gauge wire, and mark everything clearly.

And yes—we always call for utility locates before we dig. No exceptions.

Wiring for Longevity

Underground electrical work has to hold up for the long haul. We use:

  • THWN or XHHW wire rated for underground use. Learn what NEC 310.10 says about THWN wire

  • PVC or EMT conduit, properly glued and fitted

  • Weatherproof boxes and terminations

  • GFCI protection when required for safety

  • Expansion joints and sweeps where needed to avoid stress on the system

In neighborhoods with higher water tables like parts of Mid-City or Lakeview, we take extra care with conduit sealing and drainage to prevent corrosion and keep connections dry.

Adding Power to Outdoor Structures

If you're adding a detached garage in Metairie Club Gardens or a backyard studio near Bayou St. John, underground power is usually your cleanest option. We'll size the feeder circuit properly based on your needs—whether that’s a few lights and outlets or full panel subfeed—and make sure you’re not overloading your main service.

We can also install a subpanel at the far end if you need more flexibility, and we’ll ground everything properly so it’s safe and rock-solid.

Local Experience That Matters

We’re not a national company guessing our way through your property. We’re local electricians who know the flood zones, the drainage quirks, and the real-world conditions your wiring will face here in New Orleans and Metairie.

We’ve done underground jobs in tight Uptown alleys, long driveway runs in Kenner, and everything in between. We take pride in doing things cleanly, efficiently, and always up to code.
