Our Values

Boston Plasterers and Cement Masons Local 534 represents skilled and licensed craftspeople across New England. We’re proud to set the standard for cutting-edge architectural design and durable construction.

Founded in 1915, Local 534 was organized to promote quality in our industry and ensure that plasterers and cement masons could collectively bargain for better labor standards. With our world-class training and commitment to quality construction, we proudly build our region every day while securing safe working conditions, good wages, and fair benefits for our members and partners.

Local 534 is part of the Operative Plasterers’ and Cement Masons’ International Association (OPCMIA), the oldest Building Trades Union in the United States.



From everyday homes and offices to New England’s historic landmarks, our members bring our century-long commitment to quality craftsmanship to every project.


Plaster and concrete are ageless building materials that will stand the test of time. Our work is as durable as it is beautiful. And our partners have seen that what we build lasts for generations to come.
