Is This Trade Right for You?

✓ Perfect Fit

  • Detail-oriented and precise — glass installation has zero tolerance for error
  • Comfortable working at significant heights on high-rise curtain wall projects
  • Physically strong — large commercial glass panels can weigh hundreds of kilograms
  • Patient and methodical — rushing glazing work causes costly failures
  • Interested in architecture, building design, and aesthetics
  • Proud of visible, permanent results (every glass building downtown was built by a glazier)

⚠ Watch Out

  • Significant fear of heights — curtain wall work happens on the exterior of high-rises with no exceptions
  • Poor attention to detail — misaligned or improperly sealed glass means water infiltration and callbacks
  • Claustrophobia — some interior glazing work involves tight ceiling and wall chases
  • Weak on measurement and spatial thinking
  • Not physically capable of handling heavy glass panels and frames
Physical Demand Moderate-High
Mental Demand Moderate (layout precision, shop drawings, tolerances)
Work Environment Storefronts and interior to high-rise curtain wall exterior
Shift Work Uncommon
Travel Required Moderate
Danger Level Moderate-High (significant heights, sharp glass, heavy panel handling)
