Longevity, Reliability, Quality, Professionalism, Safety, and Integrity.  Interstate is Excellence.

We are steadfastly committed to achieving excellence in everything we do; the quality of our work, our superior level of service, the training and support offered to our employees, our focus on safety, and the lengths to which we go to meet or exceed customer expectations on every project no matter how large or small.

These are the reasons that since 1966, Interstate has grown to become the largest and most trusted merit shop electrical contractor in New England — with over 600 employees, 180 service vehicles,  and a commitment to customer satisfaction and focus on quality that is as fresh today as it was when we started out in 1966.
