Core Responsibilities

Primary Functions

Take precise field measurements and templates for windows, storefronts, curtain walls, skylights and mirrors, ensuring tolerance and alignment meet shop drawings and manufacturer specifications.
Review architectural drawings, shop drawings and submittals to verify glazing scope, material types (tempered, laminated, insulated IGUs), anchor locations, and installation sequencing.
Fabricate, cut and edge-finish glass and insulating glass units (IGUs) in the shop or on-site using glass cutters, saws, grinders and polishing equipment while maintaining dimensional accuracy and edge quality.
Install aluminum framing systems, storefronts, curtain walls and unitized glazing systems including anchors, setting blocks, gaskets, pressure plates and cover caps according to manufacturer instructions and AAMA standards.
Set and secure glass panes, mirrors and laminated assemblies using mechanical fasteners, structural silicone, gaskets, tapes and sealants to ensure water-tightness, thermal performance and structural integrity.
Install and replace window and door glazing, insulated glass units, and safety glazing in residential and commercial buildings; perform emergency glass boarding and temporary protection when required.
Apply and tool sealants (silicones, polyurethanes, butyls) and backing materials correctly, following joint design requirements to achieve weatherproof and durable seals.
Perform on-site glass repairs, cutouts and patching for damaged glazing, ensuring matching glass type, color, thickness and edge finish for a consistent appearance.
Coordinate with general contractors, framers, electricians and other trades to ensure proper integration of glazing systems with building envelopes and adjacent work.
Use hoists, cranes, lifts, suction cup lifters and rigging to safely handle and place heavy glass panels and large storefront units while following safe rigging and lifting protocols.
Install hardware and accessories such as glazing stops, mullions, alley clips, anchors, and operable window components; verify hardware function and adjust for proper operation.
Seal and flash perimeters of framed openings to prevent water intrusion; inspect and test installed glazing for leaks and air infiltration; perform corrective measures as needed.
Prepare and maintain accurate jobsite documentation including daily reports, material take-offs, shop drawings redlines, field change requests and punch lists.
Assist with site layout, leveling and shimming of frames to maintain plumb, square and level conditions prior to glass installation.
Verify glass and frame labeling, thermal break continuity and overall system insulation performance per NFRC, AAMA and project specifications.
Complete quality control checks and final inspections to ensure installations are compliant with project specifications, building codes and manufacturer warranty requirements.
Maintain and operate power tools, grinders, glass drills, routers and specialty glazing equipment; conduct routine maintenance and report tool defects.
Train, mentor and supervise apprentices and helpers on safe glass handling, proper installation techniques and best practices for finishing and sealing.
Participate in pre-installation meetings and site surveys to identify potential site issues, staging areas, access, and temporary protection needs.
Dispose of scrap glass and packaging per jobsite environmental and safety protocols; maintain a clean and organized work area to minimize hazards.
Provide customer-facing service: explain repair scopes, perform on-site measurements, offer replacement options and ensure customer satisfaction during handover.
Conduct post-installation warranty and service work, including resealing, reglazing and replacing failed IGUs or hardware as requested under warranty terms.
Ensure compliance with all site safety policies and procedures, including fall protection, scaffold use, ladder safety and PPE compliance for all glazing operations.

Secondary Functions

Support estimating and take-off teams by providing field measurements, material lists and installation labor hour estimates.
Assist the shop team with glass tempering coordination, IGU ordering, and confirmation of glazing unit specifications.
Maintain inventory of glazing materials, sealants, gaskets, hardware and consumables; notify procurement of low-stock items and defective materials.
Contribute to continuous improvement by providing feedback on installation methods, tooling needs and material performance to project managers and operations leadership.
Document field issues and propose cost-effective technical solutions to maintain schedule and budget adherence.
Participate in safety toolbox talks, training sessions and certification renewals (OSHA, scaffold, lift operation).
Support site logistics and staging: coordinate deliveries, material laydown, and protection of installed glazing during follow trades.
Assist in shop layout and small batch fabrication tasks when projects require field-cut or modified glass components.
Provide on-call support for emergency glazing calls and after-hours repairs as needed.
Collect and maintain photographic records of installations, damages, and completed works for quality assurance and client communications.
