Core Responsibilities

Primary Functions

Assist lead installers by accurately measuring kitchen window openings, verifying dimensions against order specifications, and identifying any discrepancies that could affect fit or weatherproofing.
Carefully remove existing windows and trim using hand and power tools, protecting surrounding cabinetry, countertops, flooring, and fixtures to prevent damage during deinstallation.
Transport and handle glass panes, sashes, and window units safely on-site and during loading/unloading, following safe lifting practices and manufacturer handling guidelines to prevent breakage and injury.
Prepare rough openings by cleaning, leveling, shimming, and planning for flashing and drainage — ensuring surfaces are plumb and square to manufacturer tolerances before setting new frames.
Fit window frames into openings and assist with provisional fastening, nailing, or screwing while the installer checks level and square; make minor in-field adjustments using carpentry and shimming techniques.
Apply sealants, caulking, insulating foam, flashing tape, and weatherproof membranes at sills, jambs, and head flashings to achieve a watertight, airtight installation consistent with manufacturer and building-code best practices.
Install interior and exterior trim, casing, or finishing components under direction, including scribing, cutting, and fastening trim to create a clean, finished appearance in kitchen spaces.
Install sash hardware, locks, balances, screens, and operating hardware; test window operation, locking mechanisms, and ease-of-use before leaving the job site.
Assist with cutting and routing of wood, PVC, or composite trim using miter saws, routers, and hand tools, always following safety protocols and manufacturer recommendations.
Perform on-site glazing assistance: set glass, install glazing beads, apply setting blocks and glazing compounds per glazing patterns and safety standards when applicable.
Load, secure, and inventory materials and tools at the start and end of each shift; maintain an organized supply of screws, sealants, shims, and fasteners to minimize downtime.
Document installation steps, serial numbers, and photos for quality assurance and warranty records as directed by the lead installer or project manager.
Communicate professionally with homeowners or on-site contacts to confirm scheduling, explain basic post-installation care (cleaning, operation), and escalate concerns to the lead installer.
Follow job-site safety plans, use required personal protective equipment (PPE), and participate in safety briefings; report hazards, near misses, or incidents promptly to supervisors.
Assist with staging materials and protecting site areas (drop cloths, protective film) in kitchens where appliances and cabinets are exposed, minimizing risk of scuffs, debris, or contamination.
Help perform minor site repairs such as replacing damaged trim, adjusting cabinetry trim to accommodate new windows, or patching small drywall defects created during window removal.
Operate company vehicles, dollies, and material handling equipment responsibly while following loading protocols and securing windows for transport to and from sites.
Support efficiency by preparing pre-cut measurements and pre-assembling window components at the staging area when directed, saving on-site labor and reducing install time.
Participate in quality checks and final walkthroughs with the lead installer to confirm alignment, seal integrity, and aesthetic finish before customer sign-off.
Maintain cleanliness and order in the company van and job site at the end of every shift, disposing of scrap glass, old frames, and packaging in accordance with local regulations and recycling practices.
Assist estimating or project teams by collecting field measurements, photos, and notes that help produce accurate quotes and material lists for future kitchen window projects.
Learn and apply manufacturer-specific installation manuals, warranty requirements, and local building code considerations to ensure installations comply and warranties remain valid.
Support scheduling and logistics by coordinating with suppliers, dispatchers, and the lead installer to confirm delivery times, material availability, and on-site readiness.
Attend on-the-job training sessions and pursue apprenticeship tasks as assigned to build competence in advanced installation, sealing systems, and glazing techniques.

Secondary Functions

Maintain and report on small tools, inventory levels of sealants, shims, screws, and glazing materials; request restock through the lead or warehouse team to prevent project delays.
Assist with pre-job site assessments, measuring and photographing kitchen openings to flag potential challenges such as rot, bowed studs, or irregular framing that require supervisor attention.
Support administrative tasks including filling out time sheets, materials usage logs, and basic digital entry of job notes for project tracking.
Help coordinate waste removal and recycling of old windows and packing materials in compliance with local disposal rules and company sustainability practices.
Provide courteous follow-up communication with homeowners to confirm satisfaction and explain routine maintenance tips that prolong window life and performance.
