Electrical Service Upgrades

Safe. Reliable. Up to Code.

Upgrading your electrical service is one of the smartest investments you can make in your home or business. Whether you’re dealing with flickering lights, tripping breakers, or adding high-powered appliances like EV chargers or HVAC systems — you need an electrical system that can handle the load safely and efficiently.

Why Upgrade Your Electrical Service?

Older homes and small commercial buildings often have outdated electrical panels that weren’t built for today’s power demands. A service upgrade ensures your system is:

  • Safe – Reduces fire hazards and electrical failures

  • Code-Compliant – Meets current National Electrical Code (NEC) standards

  • Future-Ready – Supports modern appliances, EV chargers, HVAC units, and smart home systems

  • Insurance-Friendly – Helps avoid denied claims due to outdated infrastructure

What’s Included in a Service Upgrade?

Our licensed electricians provide full-service upgrades that include:

  • Replacement of outdated electrical panels (60/100A → 200A+)

  • Meter and service entrance cable upgrades

  • New grounding and bonding for safety

  • Permits and inspections handled by our team

  • Coordination with Eversource.

We use only high-quality, UL-listed materials and ensure all work is up to code.
