About Us

First ones in, last ones out.

You see J. Derenzo Co. everywhere from jersey barriers to heavy equipment. But what do we do? J. Derenzo Co. is often the first boots on the ground preparing sites for new construction – clearing and grading the land, performing excavation, installing earth retention and foundation systems. We are also the last boots on the ground completing landscaping, installing curbing and finalizing utility hook ups.

J. Derenzo Co. has been one of New England’s premier site work contractors for over 65 years. The team’s experience ranges from large scale rural site clearing to some of the most complex, tight-site, deep hole excavations in downtown Boston. Our diversity of expertise has been a key driver in amassing a portfolio of work that is second-to-none in the industry.

Everyone at J. Derenzo Co. appreciates the importance of client relationships. A project is only as successful as the partnerships you create with clients along the way; our team puts a priority on ensuring not only seamless, well-done projects, but on successful, long lasting relationships.
