Our Story

We Take A Full-Service Approach to Mechanical Construction and Maintenance

Our History

In 1963, John Cannistraro, Sr. set out to achieve his lifelong goal of entrepreneurship with little more than $1,500 and the support of his wife, Rita. Since then, the family-owned plumbing shop he started has grown into Boston’s largest mechanical construction firm with more than 1,000 employees. Today, we’re proud to offer a full-service approach to all of your organization’s mechanical construction and maintenance needs by delivering complete plumbing, HVAC, and fire protection solutions.

Building With Intelligence. When you partner with Cannistraro, we leverage 56+ years of experience with the latest technology and self-performing fabrication capabilities to streamline any mechanical construction or maintenance project.
