Panel Replacements & Service Upgrades
Powering Southern Maine Homes & Businesses with Safe, Modern Electrical Panels
Your electrical panel is the heart of your property's power system—and if it's outdated, overloaded, or showing signs of wear, it could be putting your home or business at risk. If you notice electrical issues, it may be time for an upgrade.
At Josh LaFerriere Electric, we specialize in panel replacements and service upgrades that give you the capacity, safety, and reliability your property demands. Whether you're upgrading an aging fuse box, expanding to 200-amp service, or adding a sub-panel, we handle every detail with precision and care.

Signs You May Need a Panel Upgrade
Not sure if your panel needs attention? Here are some common warning signs that it may be time for an upgrade. For urgent panel issues, our emergency repair service is available around the clock.
What We Offer
Main Panel Replacement
We replace outdated, damaged, or undersized electrical panels with modern, code-compliant panels from trusted manufacturers. This ensures your home or business has a safe and reliable electrical foundation. We also install whole-house surge protection to safeguard your new panel.
Service Upgrades (100A to 200A or 400A)
If your property needs more power, we upgrade your electrical service to 200-amp or even 400-amp capacity. This is essential for homes adding EV chargers, heat pumps, hot tubs, or large additions.
Sub-Panel Installation
Need additional circuits for a workshop, garage, basement, or addition? We install sub-panels to extend your electrical capacity without overhauling your entire system. A sub-panel is often paired with a generator installation and transfer switch for backup power.
Code Compliance Updates
We ensure your panel and electrical service meet all current National Electrical Code (NEC) requirements, keeping your property safe, insurable, and up to date. Upgrades often go hand in hand with bathroom fan installation and other code-required improvements.
Common Reasons for Panel Upgrades
- Remodeling your kitchen, bathroom, or other living spaces
