From the initial design to the final inspection, our team ensures every addition or remodel is powered efficiently, safely, and beautifully.
Home expansions require more than just a few extra outlets. Our licensed electricians specialize in residential electrical renovations that integrate seamlessly with your existing system. Whether you’re adding a master suite, upgrading your kitchen, or finishing a basement, we handle every step, from replacing outdated wiring to installing modern, energy-efficient systems.
We meet with you (and your contractor, if applicable) to design an electrical plan that supports your vision. We review architectural drawings, calculate load requirements, and ensure all designs comply with NH & MA electrical codes and permitting standards.
Our licensed electricians install wiring, outlets, lighting, and panels with precision, coordinating with other trades for a smooth construction process. Every connection is tested for safety and performance.
Before we wrap up, we perform a thorough inspection and arrange for all required code compliance checks. Your new space is ready to use the moment we finish.
