CM Conway Construction, Inc.

CM Conway Construction does the work that happens before a building goes up. The Lynnfield company handles site work, utilities, drainage and septic installation on commercial and residential projects, and rents equipment and plows snow alongside it. It describes itself as family-owned and operated, woman-owned, and says it has been delivering construction services for more than two decades. One of those claims can be checked against a public registry, and it holds: the Massachusetts Supplier Diversity Office shows CM Conway Construction, Inc. holding an active Women Business Enterprise certification, valid through March 2028. That carries weight on public and institutional projects, where WBE participation is often written into the bid. Everything else here comes from the company's own site, which is why no rating appears — there is nothing independent to weigh it against. Ask for the addresses of recent septic or site jobs and the general contractors or towns that hired them, confirm insurance, and get the scope, price and schedule in writing before work starts.
