Our Electrical Services
From emergency fixes to complete system overhauls, we handle every electrical need your Caledonia property demands.
Electrical Repairs
Faulty wiring doesn't wait for business hours. Power outages don't check your calendar. When your electrical system fails, you need someone who answers the call and shows up ready to fix it. We troubleshoot the problem, identify what's broken, and restore power fast - whether it's your panel, lighting circuits, or wiring. Emergency or scheduled, we work around your timeline.
Electrical Panel Upgrades For Homes & Businesses
Adding an EV charger, hot tub, or upgraded HVAC system? Your old panel might be maxed out, or worse, failing to trip when it should, creating a fire hazard. We replace outdated panels with modern systems that handle your load safely, meet current codes, and protect your property from electrical fires caused by overheating circuits.
Generator Installations
Wisconsin storms knock out power when you need it most. Your sump pump stops. Your HVAC shuts down. Business operations freeze. A backup generator keeps critical systems running so you're not left in the dark. As an official GENERAC-aligned contractor, we install whole-home generators that auto-start during outages.

Schedule An AppointmentNew Construction Work
Building from the ground up or gutting that kitchen? Your electrical system needs to be designed right from the start with proper load calculations, strategic outlet placement, and code-compliant wiring. We map out your entire system based on your blueprints, install panels that match your power needs, and wire everything so it works from day one.
EV Charger Installations
Installing a home or business charger means convenience, cost savings, and (for businesses) a competitive advantage that attracts EV-driving customers. We install Level 1 and Level 2 chargers, verify your panel can handle the load, help you choose the right equipment, and manage permits and inspections.
Complete Rewiring Services
Outdated systems can't support modern electrical loads, fail inspections, and create serious fire risks. We rewire homes and commercial buildings to bring them up to code, eliminate safety hazards, and ensure your electrical infrastructure can handle what you're plugging into it.

We serve commercial businesses and residential homeowners across Caledonia with the same licensed expertise and attention to detail.

Client Reviews
I contracted S4 Electric to replace my Service panel/breaker box at my house I'm very satisfied with the work they did. They showed up on time each day and when they where done the took time to explain how everything worked. I'd definitely tell my friends and family to go with them for their next home project.
As a busy retail store, responsiveness is everything and they've consistently gotten back to us quickly, every time. Their work is not only fast but also top-notch. You can tell they really know their stuff, and they've handled every job we've thrown their way with skill and professionalism.
