  • Are you licensed and insured?

    Yes — we are fully licensed and insured electricians in Connecticut (License #E1200185). Every project we complete meets state and local building codes for safety, compliance, and reliability.

  • Do you handle both residential and commercial electrical work?

    Absolutely. Our team provides comprehensive electrical services for homes, offices, retail spaces, restaurants, and other commercial buildings. From wiring and lighting to generators and smart systems, we handle projects of all sizes.

  • How do I know if I need to upgrade my electrical panel?

    If your breakers trip frequently, lights flicker, or you’re adding new appliances or EV chargers, it may be time for a panel upgrade. Our electricians can inspect your system and recommend the right solution to keep your property safe and properly powered.

  • What should I expect during a service visit?

    We start by discussing your issue or project goals, then perform a professional inspection or estimate. You’ll receive a clear explanation and upfront pricing before any work begins, and our electricians will complete the job neatly, efficiently, and to code.

  • Can you install smart home systems or automation?

    Yes — we specialize in smart home and specialty electrical installations, including lighting controls, thermostats, cameras, and home entertainment systems. Our team ensures your devices are safely wired, properly integrated, and easy to use.
