Our Trades

Three Trades. One Union.

Plasterers

Skilled in interior and exterior plaster, stucco, EIFS, and decorative finishes. Plasterers create the surfaces that define the look and feel of buildings.

Cement Masons

Masters of concrete flatwork — floors, sidewalks, highways, and structural slabs. Cement masons build the foundation of modern infrastructure.

Fireproofers

Specialists in spray-applied fireproofing that protects steel structures and saves lives. One of the most in-demand trades in commercial construction.
