Full-Service Electrical Work for Homes & Businesses

From outlets to whole-home upgrades, CJH Electrical handles every job with care—especially the complex ones others avoid.

What We Do

CJH Electrical offers a complete range of residential and small commercial electrical services throughout New Hampshire, Maine, and Massachusetts. Whether you're updating an older system or starting fresh with new construction, we approach every job with craftsmanship and respect.

We’re known for the careful way we work—especially in homes where others might punch holes and make a mess. Our experience spans from basic service calls to full-scale rewiring, always with code compliance, safety, and long-term function in mind.

Our Core Electrical Services

We specialize in updating homes built before 1960. Whether it's removing knob & tube wiring, grounding ungrounded outlets, or upgrading lighting and switches, we do it with minimal disruption to original finishes and materials.

Service & Panel Upgrades

Today’s appliances and systems demand more power than older electrical panels were built to handle. We offer clean, code-compliant upgrades to your electrical service and panel—built to last and sized to grow with you.

New Construction Wiring

Yes, we love old homes—but we handle new ones, too! Whether you’re building a new home or adding onto an existing structure, we wire from the ground up with future-proofing in mind.

Lighting, Switches & Fixtures

From antique fixtures to smart dimmers and recessed LEDs, we install and upgrade ceiling lights, wall sconces, and control systems with precision.

Complex Wire Fishing

Can’t cut the walls? No problem. We specialize in creative solutions for routing wires through tight spaces and old plaster without visible damage.

Troubleshooting & Repairs

Lights flickering? Breakers tripping? Outlets not working? We’ll track down the source and fix it right—without cutting corners.

GFCI & AFCI Protection

We install and replace GFCI and AFCI breakers and outlets to keep your family safe and your system up to code.

Generator Wiring & Transfer Switches

Prepare your home or small business for outages with our generator-ready wiring and transfer switch installations.
