Electricians install, alter, test, and repair the wiring, panels, and fixed equipment that carry electrical power through buildings and sites. Much of the day is reading drawings, running and terminating cable, and proving a circuit is safe before it is energised. Fault-finding on systems that are already live is a routine part of the work and carries genuine safety consequences.

Industrial electricians keep the electrical side of plant and production equipment running: motor controls, drives, sensors, and the control panels that tie them together. The work leans heavily on diagnosis, because a stopped line has to be traced back to a cause quickly and safely. Shift coverage and callouts are common where plant runs around the clock.

Plumbers install and repair the water supply, drainage, venting, and fixture systems in homes, commercial buildings, and industrial premises. The work combines physical installation in tight and awkward spaces with careful layout, because pipework has to fall correctly and pass inspection. A large share of the job is service work: finding a leak or blockage in a system somebody else built.

Steamfitters and pipefitters build and maintain the piping that carries steam, high-pressure fluids, gases, and process media through plants, boiler rooms, and large buildings. The work is drawing-driven and tolerance-sensitive, since joints have to hold pressure and expansion has to be allowed for. Much of it happens on industrial sites, at height or in confined spaces, often during shutdowns.

Gasfitters install, service, and certify natural gas and propane piping, meters, burners, and appliances. Because an undetected leak or a badly vented appliance is dangerous, the trade is tightly tied to codes, testing, and documented certification. Work ranges from residential furnaces and water heaters to commercial kitchen and industrial burner equipment.

Refrigeration mechanics build and service the cooling systems used by supermarkets, cold stores, food processors, ice rinks, and process plants. The work is more system-oriented than domestic HVAC: racks, condensers, evaporators, and controls have to be balanced against a load, and refrigerant handling is regulated. Failures are urgent because stock and process material are at risk.

Carpenters lay out, cut, and assemble the timber and engineered wood elements of a building, from framing and formwork through to stairs, doors, and trim. The trade spans rough work where speed and structural accuracy matter and finish work where appearance and tight fit matter. Most carpenters also spend time setting out from drawings and correcting for a site that is not perfectly square or level.

Bricklayers and stonemasons build and repair walls, facades, chimneys, and structures from brick, block, and stone bedded in mortar. The work is physically demanding and weather-exposed, and it rewards a steady eye, because courses have to stay level and plumb over long runs. Restoration and repointing work on older masonry is a distinct and skilled part of the trade.

Welders join and repair metal using processes such as stick, MIG, TIG, and flux-cored arc welding, working to a specified procedure and often to a formal qualification test. The trade rewards steady hand control and preparation, since fit-up, cleanliness, and heat management usually determine whether a weld passes inspection. Work ranges from shop fabrication to structural and pressure work on site.

Millwrights install, align, maintain, and rebuild industrial machinery: pumps, gearboxes, conveyors, turbines, presses, and the drives that connect them. Precision alignment and bearing work are core to the trade, because a shaft that is out by a small amount will destroy couplings and seals over time. Much of the work happens during shutdowns or in response to a breakdown.

Boilermakers fabricate, erect, and repair boilers, pressure vessels, tanks, and heavy plate structures. The work is heavy, code-governed, and frequently carried out inside vessels or at height during plant outages. Rigging, layout, cutting, fitting, and welding are all part of the same job.

Structural ironworkers erect the steel frames of buildings, bridges, and industrial structures, and place the reinforcing steel that concrete is poured around. The work is outdoors, at height, and coordinated closely with crane operations, so rigging knowledge and fall protection discipline are inseparable from the trade. Accuracy matters because a frame out of plumb is expensive to correct.

Glaziers cut, handle, and install glass and glazed systems: windows, doors, storefronts, curtain wall, mirrors, and shower enclosures. Handling is a defining part of the job, since panels are heavy, awkward, and unforgiving of a dropped edge. Weatherproofing and sealing are as important as the glass itself, because a badly sealed unit leaks and fails.

Insulators apply thermal, acoustic, and fire-stopping insulation to pipework, ductwork, vessels, and building elements, then finish it with jacketing or cladding. The work is measurement-heavy and pattern-based, particularly around fittings and valves. Because older buildings and plant may contain asbestos or other hazardous materials, controlled removal and respiratory protection are part of the trade.

Roofers install and repair roof coverings and the layers beneath them, working with shingles, membranes, metal, tile, and built-up systems. It is outdoor, weather-dependent work carried out at height, and fall protection is central rather than incidental. Diagnosing an existing leak is often harder than installing new covering, because water travels before it shows.

Painters and decorators prepare surfaces and apply paint, coatings, wallcoverings, and finishes to buildings and structures. Preparation is the bulk of the work: filling, sanding, masking, and priming decide how the finish looks and how long it lasts. Industrial and marine coatings work is a distinct branch with its own surface preparation and inspection requirements.

Heavy-duty equipment technicians maintain and repair the diesel-powered machines used in construction, mining, forestry, and agriculture: excavators, loaders, dozers, haul trucks, and similar equipment. The systems are large and high-energy, spanning diesel engines, hydraulics, powertrains, and electronic controls. A lot of the work happens in the field, at the machine, in whatever weather the site has.

Aircraft maintenance engineers inspect, service, repair, and certify aircraft and their systems so they can be released back to service. The trade is documentation-driven: every task is done to an approved procedure and recorded, and the certifying signature carries legal weight. Work is regulated by the national aviation authority and often runs on shifts around flight schedules.

Marine service technicians maintain and repair boats and their engines, drives, electrical systems, and onboard equipment. Saltwater and constant vibration make corrosion and fatigue everyday problems, and a fault at sea has different consequences than one on a driveway. Work happens in yards, at docks, and sometimes on the water during sea trials.

Elevator mechanics install, maintain, test, and repair elevators, escalators, and other elevating devices. The trade sits at the intersection of mechanical, electrical, and control systems, and it is governed by safety codes and periodic inspection because the equipment carries the public. Entrapment and breakdown callouts mean on-call rotations are common.

Powerline technicians build and maintain the overhead and underground networks that distribute electricity from substations to customers. The work is outdoors in all weather, at height or in trenches, and around conductors that can be energised at high voltage. Storm restoration means unpredictable hours and long shifts when the network is damaged.

Facilities maintenance technicians keep buildings and their systems working, covering a broad mix of plumbing, electrical, mechanical, carpentry, and general repair tasks. The role is defined by breadth rather than depth: the technician handles what they are competent and permitted to do, and calls in a licensed trade for the rest. Planned maintenance rounds sit alongside a steady stream of reactive requests.

Custodians keep buildings clean, stocked, secure, and safe to occupy, working in schools, hospitals, offices, and public facilities. Beyond routine cleaning, the role usually includes minor repairs, setting up rooms, clearing snow or waste, and being the person who notices when something in the building is wrong. Shifts are often early, late, or overnight so the work does not disrupt occupants.
