Not sure if we serve your area? Give us a call and we'll let you know!
Unlike many electricians who specialize in just one area, we’re equally skilled in handling large-scale commercial projects and detailed residential work. From office wiring to home EV chargers, we do it all.
Service Upgrades & Modern Solutions
We focus on today’s needs—EV charger installations, panel upgrades, and home automation. Customers know we’re not stuck in the past—we provide modern electrical solutions designed for modern living.
Licensed, Insured & Reliable
With Connecticut license #E1200185, our customers get peace of mind knowing every project is handled safely, up to code, and fully protected. We show up on time, do the work right, and stand by it.
Local, Customer-Focused Service
As a North Haven-based company serving a 25-mile radius, we’re not a big-box contractor. We’re a local team that cares about long-term relationships, not quick jobs.
