Electrical contractor from Gloucester, Massachusetts

Costanzo Electric is a service-oriented company dedicated to providing complete customer satisfaction. We provide comprehensive electrical and wiring work that consistently exceeds our customer’s expectations throughout all phases of the job. We strive to offer each customer with prompt, courteous, professional service at an affordable price.


As a smaller, family-run firm, it is our mission to operate a contracting business that meets and/or exceeds our customers' expectations, and to build long-term relationships by providing outstanding value without compromising our core values of quality, accountability, and workmanship.

Working in smaller teams gives Costanzo Electric a clear advantage over many of the electrical outfits on the North Shore. Smaller teams means quick, concise communication throughout the various stages of projects large and small.


Whether it is in talking with clients about what they are trying to achieve at the start of a project, communicating changes and modifications the customer requests, or in knowing that the same team will likely show up to do the next phase of the project or the next project, this kind of consistency is the cornerstone of the Costanzo Electric experience.
