How to Install a Rim Joist

Save

A rim joist is found in the subfloor of a house. It is the end piece around the room that completes the box that makes up the subflooring. Rim joists are generally made of 2-by-8 or 2-by-10 lumber of various lengths. Installing a rim joist is the final step in the installation process of the subfloor. Rim joists are installed to the sill plates around the perimeter of the subfloor before the beams and floor joists are installed.

Things You'll Need

  • Tape measure
  • 2-by-10 rim joist
  • 2-by-10 joist hanger
  • Wood screws
  • Power drill
  • Measure the length of the room where the rim joist will be installed. Run a tape measure across the width of the room and record the measurement of each side.

  • Line up the rim joist at the edge or the room and butt it up against the sill plate. Measure the width of the rim joist and purchase a joist hanger that is a similar width. For a 2-by-10 rim joist, use a 2-by-10 joist hanger.

  • Set the joist hanger up in the rim joist. Press it up against the sill plate so the rim joist is setting in the joist hanger and the pre-drilled holes are up against the sill plate.

  • Drill the 1 1/2-inch wood screws through the joist hanger and into the sill plate. Insert a screw into each pre-drilled hole on both sides of the rim joist. Set a joist hanger up on the other side of the rim joist at the other end of the room and install it to the sill plate in the same manner.

  • Line up a rim joist across the width of the room at the other end and install it in the same manner to completely enclose the subfloor. Inspect the area and verify the rim joists are secure to the sill plates.
