Powering a Bright Future for Northern New England Since 1920

Founded in 1920, E.S. Boulos Company (ESB), is among the oldest, largest, and most experienced electrical and telecommunications contractors in the northeastern United States.

Headquartered in Westbrook, Maine, ESB is the trusted source for quality electrical and telecommunications installations for major construction projects throughout Northern New England and beyond.

Today, ESB is a single source provider of electrical and tel/data installation services for Northern New England’s most dynamic and complex projects.

Our commercial division’s broad capabilities have led to an ever-expanding project portfolio that includes many of the region’s most prominent healthcare, educational, technology and corporate facilities, as well as major bridge and transportation projects.

While maintaining a premier electrical substation contractor status, ESB’s Utility Division has been on the leading edge of the renewable industry in recent years. We have consistently and successfully performed large, utility-scale solar PV installation projects in the northeast.

ESB’s seasoned team of professionals performs a variety of commercial, industrial and utility work from downeast Maine to southern Connecticut.

From large civic centers and hospitals in Maine, power stations in Rhode Island, substation and switchyards in Vermont to moveable bridge projects in Massachusetts, ESB has built a strong reputation for quality, safety and value.


2020 is E.S. Boulos’ 100th year in business!
