Glaziers

Glaziers typically perform the following tasks: • Read and interpret blueprints or specifications to determine size, shape, color, type, or thickness of glass, location of framing, installation procedures, or staging or scaffolding materials required. • Determine plumb of walls or ceilings, using plumb lines and levels. • Install pre-assembled metal or wood frameworks for windows or doors to be fitted with glass panels, using hand tools. • Fabricate or install metal sashes or moldings for glass installation, using aluminum or steel framing. • Operate cranes or hoists with suction cups to lift large, heavy pieces of glass. • Set glass doors into frames and bolt metal hinges, handles, locks, or other hardware to attach doors to frames and walls. • Cut, fit, install, repair, or replace glass or glass substitutes, such as plastic or aluminum, in building interiors or exteriors or in furniture or other products. • Drive trucks to installation sites and unload mirrors, glass equipment, or tools. • Load and arrange glass or mirrors onto delivery trucks, using suction cups or cranes to lift glass. • Measure mirrors and dimensions of areas to be covered to determine work procedures. • Cut and attach mounting strips, metal or wood moldings, rubber gaskets, or metal clips to surfaces in preparation for mirror installation. • Pack spaces between moldings and glass with glazing compounds and trim excess material with glazing knives. • Assemble, erect, or dismantle scaffolds, rigging, or hoisting equipment. • Cut and remove broken glass prior to installing replacement glass. • Secure mirrors in position, using mastic cement, putty, bolts, or screws. • Measure and mark outlines or patterns on glass to indicate cutting lines. • Grind or polish glass, smoothing edges when necessary. • Fasten glass panes into wood sashes or frames with clips, points, or moldings, adding weather seals or putty around pane edges to seal joints. • Score glass with cutters' wheels, breaking off excess glass by hand or with notched tools. • Cut, assemble, fit, or attach metal-framed glass enclosures for showers, bathtubs, display cases, skylights, solariums, or other structures.
