Joiners are skilled tradespeople who specialize in creating and installing wooden structures and fittings in buildings. They typically work with various types of wood, including softwoods and hardwoods, and may use a variety of tools and machinery to create precise cuts and joints. The work of joiners is essential in the construction of buildings, as they are responsible for creating many of the structural elements such as walls, floors, and roofs, as well as decorative features such as doors, windows, and staircases.

One of the key responsibilities of joiners is to create accurate, precise cuts and joints in wood. This is typically done using hand tools such as saws, chisels, and planes, as well as powered tools such as routers and mortisers. Joiners must have a strong understanding of the properties of different types of wood and how they respond to different cutting and shaping techniques. They must also be able to read and interpret technical drawings and specifications, and be able to work to precise measurements.

Joiners are also responsible for installing the wooden structures and fittings that they create. This may involve working on scaffolding or other height-access equipment, and may require a high level of physical fitness and manual dexterity. Joiners must also be able to work safely and follow all relevant health and safety regulations.
