Key Responsibilities and Required Skills for Joiner

🎯 Role Definition

A Joiner is a skilled tradesperson who measures, cuts, shapes, assembles and installs timber and composite joinery items for both workshop (bench) and site installation environments. This role covers production of doors, windows, staircases, fitted kitchens, cabinetry and architectural woodwork, and requires strong technical drawing interpretation, precision woodworking, finishing skills and adherence to health & safety and building regulations. Ideal candidates will combine hands-on craftsmanship with site installation experience, tool and machinery competence (including some CNC exposure), and strong communication skills to coordinate with clients, site teams and sub-contractors.

Core Responsibilities

Primary Functions

Read, interpret and work from technical drawings, shop drawings, architectural plans and specifications to lay out, measure and mark timber components accurately to tight tolerances.
Set out, cut and prepare timber, MDF, plywood, laminate and composite materials using hand tools and power tools (saws, routers, planers, thicknessers, jointers) to produce precise joinery components.
Manufacture, assemble and install bespoke items such as doors, door frames, window frames, skirtings, architraves, staircases, fitted kitchens, wardrobes and built-in furniture both in the workshop and on site.
Use jigs, fixtures and templates to ensure repeatable accuracy when machining components and to maintain consistent quality across production runs.
Operate woodworking machines safely and efficiently, including table saws, band saws, spindle moulders, CNC routers and sanding equipment; carry out routine machine set-up and adjustments.
Produce accurate shop work and site templates for complex items (e.g., stair components, curved profiles, or irregular openings) and transfer templates to finished pieces.
Assemble joints using traditional and modern techniques (mortise and tenon, dovetail, dowel, biscuit, lamination, mechanical fixings and adhesives) and check for square, alignment and structural integrity.
Fit and fix finished joinery on site, including setting out, levelling, scribing, trimming, bedding, sealing and final adjustment of locks, hinges, catches and hardware to manufacturer and regulatory standards.
Prepare, apply and inspect surface finishes including priming, staining, varnishing and lacquering to meet specification and client expectations and to ensure durable, high-quality finishes.
Carry out site surveys, take accurate site measurements, advise on material options and methods, and produce material take-offs to support quoting and production planning.
Collaborate with project managers, estimators and workshop staff to sequence production, manage lead times and prioritize work to meet project milestones and client deadlines.
Follow and enforce health & safety procedures including safe use of tools, machine guarding, PPE, COSHH requirements, manual handling protocols and site-specific safety plans.
Inspect finished joinery items for fit, finish, quality and compliance with drawings and job specifications prior to installation or handover; document and rectify any defects.
Maintain and service hand tools and power tools, perform preventative maintenance on machinery and report any defects to minimise downtime and ensure a safe working environment.
Cut and prepare materials for trade finishes and secondary items (e.g., glass panels, metal fixings, seals) and coordinate with sub-contractors (glaziers, metalworkers, painters) where necessary.
Interpret structural and architectural constraints when installing heavy items (e.g., staircases, timber frames) and coordinate lifting, bracketing and anchorage with site teams to ensure safe installations.
Prepare items for transportation, pack securely, label and oversee delivery or handover to site to avoid damage and ensure components arrive ready for installation.
Train, mentor and supervise junior joiners, apprentices and shop assistants by demonstrating techniques, reviewing work and providing constructive feedback to improve craft standards.
Maintain accurate production records, timesheets, job cards and non-conformance reports; contribute to continuous improvement by suggesting process or layout changes to increase efficiency.
Apply knowledge of building regulations and standards (e.g., fire doorsets, stair pitch regulations, escape routes) when manufacturing and installing joinery to ensure compliance.
Undertake remedial or aftercare visits as needed to adjust, repair or replace joinery items following installation and to ensure customer satisfaction.
Work flexibly across workshop and site environments, adapt to changing job requirements, and support multi-trade teams on larger projects when required.

Secondary Functions

Support estimating teams with material lists and practical input on time and complexity for bespoke joinery quotations.
Assist with stock control: receiving, inspecting and storing timber and consumables to minimise waste and maintain quality.
Participate in pre-start meetings and toolbox talks to align with project safety targets and schedules.
Support the organisation's quality control processes by completing checklists and participating in internal audits.
Contribute to continuous improvement initiatives, suggesting improvements to workflow, tooling and materials to save time and reduce defects.
Help maintain a clean, organised workshop and site areas, including correct disposal of off-cuts and recycling of timber waste.
Collaborate with suppliers to source specialist materials, hardware and bespoke components to meet aesthetic or performance requirements.
Provide after-sales advice to clients on care and maintenance of finished joinery items and recommend warranty or service solutions when necessary.
Aid in the development of templates, standard details and production drawings to build a library of repeatable components for future jobs.
Occasionally cover additional duties such as fitting external cladding, decking or lightweight timber framing where cross-skilled.
