Our Electrical Rewiring and Lighting Installation Process

Electrical Assessment and Design

We begin with a comprehensive electrical assessment of your existing garage and main electrical panel to determine upgrade requirements and capacity needs. Our electricians evaluate your current electrical service, identifying any necessary improvements to support your garage conversion's electrical demands.
