What Olson Brothers Electric Does

Assess the Site and Plan a Simple, Safe Route

We review property layout, utilities, and site conditions to design a simple, safe, and efficient underground wiring plan.

Perform Trenching or Directional Boring

Depending on your property and the scope of the work, we:

Dig trenches to the correct depth for conduit
Use directional boring to minimize surface disruption
Avoid existing utilities using proper locates
Ensure soil backfill and compaction are clean and safe

Directional boring keeps disruption low and protects finished surfaces like parking lots, sidewalks, and landscaped areas.

Install Commercial-Grade Conduit Systems

We install conduit appropriate for the application:

PVC conduit for most underground runs
Rigid metal conduit for high-security areas
EMT or flexible conduit in commercial interior transitions
Weather-rated fittings and junctions

Conduit protects wiring from damage and creates a long-lasting electrical pathway you don’t have to think about again.

Pull Wiring and Connect to Panels or Equipment

We install wiring for:

Exterior lighting systems
Parking lot pole lights
EV charging stations
Security and access control systems
Outdoor refrigeration or HVAC
Signs and wayfinding systems
Outbuildings, shops, and warehouses

If your panel needs more capacity, we will recommend a simple service upgrade that ensures everything operates safely and reliably.

Testing, Verification & Code Compliance

We test all circuits, verify grounding, ensure conduit is sealed where required, and prepare the entire installation for inspection.
