Of the many terms that are used for people who work with wood, joinery may not be so familiar. While doubtless most people have heard of joinery, the exact meaning may not be known or it may be confused with another profession that has to do with wood.
What is Joinery?
Put simply, it is when two or more pieces of wood are joined together. The wood can be put together with nails, screws, or glue. Or the joining can be accomplished through the use of complicated joints that bring the wood together by their very shape. The purpose is primarily to hold the wood together securely, but it can also be used in a decorative function as well.
You can find joinery in most woodworking endeavors such as cabinetry, doors, flooring, furniture, windows, and more. You see it in most every home, office, and facility, yet it is not by definition carpentry.
Joiner vs. Carpenter
The difference between a joiner and carpenter is subtle, but an important one. The primary difference between a joiner and carpenter is that, the joiner joins wood to assemble the objects at the workshop whereas the carpenter put them together on site.
In other words, for creating stairs or window frames you would probably hire a joiner over a carpenter because they specialize in that particular type of woodworking product. Just as an optometrist is preferable to a general doctor if you want your eyes examined.
This is because joining is a specialist area of the carpentry field. This means that a carpenter will use joining in their overall work, but they are a generalist as opposed to a joiner who is a specialist. You will then hire a carpenter when you want to install the stairs and window frame at your home.
