Underground Electrical Services, Directional Drilling, Cable Plowing and Trenching

Reliable underground electrical infrastructure is critical for homes, cabins, businesses, and utility systems across Northern Wisconsin. At Jolma Electric, LLC, we provide professional trenching, excavating, plowing, and horizontal directional drilling (HDD) services for underground electrical installations and repairs.


From installing new underground electrical service to converting overhead power lines, our team has the equipment and expertise to safely complete projects in residential neighborhoods, rural properties, lake homes, and commercial developments.

Many homes and cabins in Northern Wisconsin still rely on overhead electrical service lines supported by poles. While these systems have been used for decades, they can create both practical and reliability challenges for property owners.

Underground electrical service offers several benefits:

More Usable Space on Your Property

Improve lake views or outdoor living areas

By converting overhead service to underground, the electrical pole can often be removed, giving homeowners more usable space and a cleaner property layout.

Reduced Risk of Power Outages

Overhead power lines are more vulnerable to weather and environmental damage, including:

  • Falling trees
  • Heavy snow and ice buildup
  • High winds
  • Storm damage

Underground electrical service reduces exposure to these risks, which can help improve reliability and reduce outages for homes and cabins.

Improved Property Appearance

Removing overhead lines can dramatically improve the look of a property, especially for:

  • Lake homes
  • Vacation cabins
  • Residential neighborhoods
  • Commercial developments

Many homeowners choose underground electrical service to create a cleaner and more modern property appearance.

Horizontal Directional Drilling (HDD) is a specialized technique used to install underground utilities without digging long open trenches across the ground surface.


Instead of excavating large areas, a drill is guided underground along a precise path to install electrical conduit or utilities beneath the surface.


This technology is ideal for running electrical lines:

  • Under driveways
  • Beneath roads
  • Across landscaped yards
  • Under sidewalks or parking lots
  • Near lakeshores and environmentally sensitive areas

Because the process minimizes surface disturbance, HDD is a more efficient and less invasive solution for many underground electrical installations.

Benefits of Horizontal Directional Drilling

Directional drilling offers several advantages over traditional trenching.

Minimal Surface Disruption

Lawns, landscaping, roads, and driveways remain largely intact because the drilling occurs underground.

Faster Installation

Many projects can be completed more efficiently compared to large excavation work.

Ideal for Hard-to-Reach Areas

HDD can install utilities under obstacles such as:

  • Roads
  • Buildings
  • Concrete
  • Water features
  • Environmentally sensitive areas

Reduced Restoration Costs

Because less surface area is disturbed, property restoration costs are often lower.

Jolma Electric provides a full range of underground electrical installation and repair services for residential, commercial, and utility projects.

Fault Locating and Electrical Repairs

When underground electrical lines fail, locating the exact problem quickly is critical.

Our technicians use specialized equipment to identify underground electrical faults and complete repairs efficiently, minimizing downtime for homes and businesses.

Site Restoration and Reclamation

After underground utility work is complete, proper site restoration ensures the property returns to its original condition.

Reclamation services may include:

  • Backfilling trenches
