Union Partners
Share |

The M&SCA is proud to work in partnership with two local unions from which our contractor members hire their trade labor employees. This partnership extends beyond the day to day operations. Leaders from these organizations work on progressive ideas and initiatives to enhance training, safety, and market share for member contractors.

The history of the Plumbers in Philadelphia dates back to May 12, 1900 with the formation of Plumbers Local 123. For over 100 years, Plumbers have been protecting the health of Philadelphia area citizens through quality work that is unparalleled because of their training programs. The intensive apprenticeship program provides the skills the members will use in many different construction applications, including heavy industrial, pharmaceutical, commercial and residential markets. The workforce takes pride in providing high quality, reliable, and often times sophisticated piping systems to the end user. From underground installation to final connections of fixtures and equipment, a Plumber is required to have all the physical and mental skills needed to get the job done right the first time.
