One integrated contractor for the full spectrum of utility-grade infrastructure — from medium-voltage distribution to fiber backbone, wireless, and renewable interconnects.
Three generations.
One standard of work.
Founded by Jack McDonough in 1969, McDonough Electric Construction Corp. has grown from a New England powerline contractor into an integrated infrastructure company. Today, Kevin and Ryan McDonough continue that legacy — combining decades of field expertise with a modern fleet and an expanded scope of work that includes medium-voltage, fiber, wireless, and renewable interconnect systems.
We don't subcontract the hard parts. We own the equipment and the expertise.
From energized medium-voltage environments to remote fiber deployment and renewable interconnects, McDonough brings full self-perform capability — union craft labor, specialized fleet, and field leadership with decades of utility experience.
Let's talk directly.
