• Installing glass in windows, doors, storefronts, partitions, and curtain walls.
• Applying weather-stripping, putty, or silicone sealants to ensure frames are airtight and watertight.
• Operating lifting equipment, such as cranes or suction lifters, to hoist heavy glass panels into position.
• Repairing or replacing broken glass in existing structures while adhering to safety regulations.
• Collaborating with other tradespeople, such as carpenters or metal workers, to ensure seamless integration of glass into building structures.
