Nadeau Corporation is a family-owned business proudly serving New England. In 1984 Ernie Nadeau left his VP role at Weststar Associates to set out on his own.  His mission was to create a general contracting firm with a “client-first” mentality. Through his commitment to treat every project as an opportunity to earn the next, the company grew steadily.

Three decades later, client relations and delivering on every owner’s unique needs, remains the foundation of everything we do at Nadeau Corporation. It forms the basis for success on each and every project we take on.


Our most valuable asset at Nadeau Corporation is our staff. Keeping them safe along with the other project participants and the general public is our priority. Our safety manual is in strict compliance with OSHA standards and is updated regularly as new initiatives are publicized. Our written safety manual is approved by some the most scrutinizing agencies including the United States Air Force and US Dept. of Veterans Affairs. We refuse to take safety for granted and believe it is a sound investment that ultimately lowers costs for our clients and for us.
