About Us

NSMC, advancing the craft since 1984

NSMC was founded in 1984 as a specialized plumbing and piping firm. Founder Joe Whitney had two clear goals for the company: to have the best labor force in the industry—and a leadership position in our specialties.

Now, over 30 years later, we are proud to be achieving those goals. We have a roster of repeat clients at the tops of their own industries…we have received regional and national awards for our work and our safety programs…and all our work is performed by a long-term labor force of the best-trained, safest, most dedicated plumbers in the craft.


  • Our corporate safety program has been a winner in the Associated Builders & Contractors’ prestigious STEP awards safety competition for 17 consecutive years
  • Our employees continually participate in education and training programs—creating a highly skilled labor force dedicated to NSMC’s approach to quality, safety and client satisfaction
  • Our work has received regional & national awards for excellence from Associated Builders and Contractors’ and Plumbing Heating Cooling Contractors (PHCC) association
  • Our client list includes the region’s leading biotechnology and pharmaceutical firms, advanced technology companies, hospitals and schools—and the general contractors and construction managers that build them

Over 30 years serving the region’s finest companies

NSMC performs hundreds of large and small projects annually. We have worked with virtually every biotech company in Massachusetts, plus many of the region’s major pharmaceutical, microelectronics & industrial process firms, major hospitals, and health care facilities, and educational facilities from independent K–12 schools to colleges & universities.

These clients turn to NSMC for our experience and expertise—and for our ability to deliver top quality on the tight schedules that go with tight budgets. For a copy of our client list, call us.
