Terms of the Trade: What Is a Joist? Terms of the Trade: What Is a Joist?

In the world of architecture and construction, joists are integral. They’re a series of strong lengths of lumber, steel or sometimes even concrete running parallel to the ceiling, floors and beams they support. Joists can be considered the skeleton of a house, floor, or ceiling because they support the surrounding structure (and everything we fill that structure with). Therefore, they require replacement if they are damp, sag, or show signs of termite decay or a general loss of structural integrity.
