In construction, a joist is a horizontal piece that runs from wall to wall, wall to beam or beam to beam. A joist is essentially considered to be one of the most supporting pieces towards the structural aspect. It focuses in on supporting beams and other pieces in the floor, ceiling and roof.
Different situations call for different joists. Generally floor joists are 2 x 12.
The recommended spacing for deck floor joists is typically 16 inches on center.
Yes. Rafters and flloor joists do not have to run the same direction.

To locate floor joists under carpet, you can use a stud finder or a strong magnet to detect the nails or screws that secure the carpet to the floor. Once you find the fasteners, you can trace a straight line to identify the position of the floor joists. Alternatively, you can look for subtle bumps or seams in the carpet that may indicate the presence of floor joists underneath.

The size of wood used for floor joists typically ranges from 2x8 to 2x12 inches, depending on the span and load requirements of the floor.
To properly sister floor joists, you should attach new joists next to existing ones to provide additional support. Use construction adhesive and nails or screws to secure them together. Make sure the new joists are the same size and length as the existing ones for a strong and level floor.
To find floor joists in your home, you can use a stud finder or look for nails or screws in the baseboards or ceiling. You can also measure 16 or 24 inches from a wall, as joists are typically spaced at these intervals. Another method is to locate a floor vent or electrical outlet, as they are often attached to joists.
To properly sister floor joists, you should attach new joists next to the existing ones using construction adhesive and nails or screws. This reinforcement helps distribute the load and strengthen the weakened or damaged floor structure.
The recommended spacing for floor joists in a residential construction project is typically 16 inches on center.
The best method for repairing floor joists using floor joist repair plates is to first assess the damage to the joists and determine the appropriate size and type of repair plates needed. Next, secure the repair plates to the damaged joists using screws or nails, making sure they are properly aligned and flush with the joists. Finally, reinforce the repair by adding additional support, such as sistering new joists alongside the damaged ones. Regularly inspect the repaired joists to ensure they remain structurally sound.
