What you'll do

Day-to-day tasks

As a window fabricator, you could:

  • measure, cut and drill materials like UPVC, aluminium and wood
  • interpret design plans and operate CNC machinery
  • assemble window and door frames, conservatory panels and screens
  • fit seals, hinges, handles and locks using hand and power tools
  • check the quality of finished products ready for delivery
  • assist with on-site surveys on potential jobs

Working environment

You could work in a factory, in a workshop, at a client's business or at a client's home.

Your working environment may be physically active.

You may need to wear protective clothing.

Career path and progression

With experience, you could move into supervisory or quality control positions. You might become a warehouse, production or trade counter manager.

You could also use your skills to work in other areas of manufacturing, like CNC machining.

What it takes

Skills and knowledge

You'll need:

  • knowledge of maths
  • the ability to use, repair and maintain machines and tools
  • knowledge of building and construction
  • to be thorough and pay attention to detail
  • the ability to use your initiative
  • physical skills like movement, coordination and dexterity
  • knowledge of manufacturing production and processes
  • the ability to accept criticism and work well under pressure
  • to be able to carry out basic tasks on a computer or hand-held device

Most relevant

  • Mathematics - Window fabricators use maths constantly to take precise measurements, calculate dimensions from design plans, and work out cutting angles for frames and panels. Even small errors in measurement can mean a window doesn't fit, so accuracy with numbers is essential.
  • Design and Technology - Window fabricators work with a range of materials like UPVC, aluminium, and wood, cutting, shaping, and assembling them into finished products. Understanding how to read technical drawings, use hand and power tools safely, and work through a manufacturing process is central to the job.
  • Engineering - Window fabricators operate CNC machinery and work with manufacturing production processes to produce precise components. Understanding how machines work, how to maintain them, and how engineering principles apply to materials and assembly is a key part of the role.

Also relevant

  • Physics - Window fabricators benefit from understanding how different materials behave under stress, heat, and pressure – for example, how aluminium and UPVC expand or contract with temperature changes. Knowledge of forces and material properties helps when assembling frames that need to be strong, weatherproof, and long-lasting.
  • Computer Science - Window fabricators may operate CNC machinery, which involves interpreting or inputting programmed instructions to cut and shape materials accurately. Understanding how computer-controlled systems work helps when setting up machines and troubleshooting production issues.
  • Business - Window fabricators who progress into supervisory, production management, or trade counter roles need to understand stock control, workflow planning, and customer service. Knowledge of how a manufacturing business operates helps with managing teams and meeting production targets.

How to become

You can get into this job through:

  • an apprenticeship
  • working towards this role
  • applying directly

You could apply to do a Fenestration Fabricator Level 2 Intermediate Apprenticeship with a manufacturing company.

This takes 1 year and 6 months to complete.

Entry requirements

To get onto an apprenticeship, you'll find it useful to have:

  • some GCSEs, usually including English and maths, or equivalent, for an intermediate apprenticeship

More Information

You could begin work as a general production worker or labourer with a window manufacturer and work your way up. There are courses you can do while working to help you get into more skilled fabrication jobs.

You could also start as a window fitter and move into fabrication work.

You can apply directly for jobs. Employers set their own entry requirements, though you'll need maths skills for taking measurements along with good practical skills.

Experience of general manufacturing and trades like window fitting or joinery may also be useful.
