How to Install a Crown Molding End Cap

You will need to know how to install crown molding ends if you're adding this trim to a room in your house. Crown molding ends are designed to create a finished termination to a piece of molding.

Step 1 – Securing the Molding

Step 2 – Measuring the End Cap Space

Use your tape measure to determine the distance between the wall and the top of the molding. If necessary, note this measurement on a piece of paper. You will use this measurement for cutting the end cap.

Step 3 – Cutting the End Cap

Use your miter saw to make a 90-degree cut from the beveled end of your cut molding. The top of the piece will be the length of the distance from the wall to the molding.
