How To Install Door Molding

by Karianne WoodJune 13, 2017

One of the most often-overlooked details in a home is the molding. Most new homes today come with builder grade moldings. They are plain, ordinary and nothing special. Having moldings installed by a professional can be costly and time-intensive. Why not do it yourself? Here’s an easy update to your moldings that you can finish in a weekend.

How to install door molding.

  1. Assess your current moldings

    We built this project on a door with a plain molding surround of 1″ x 6″ boards. Most doors have a casing of 2½” to 3″ wide. You can modify this project to fit a standard door casing, or you can remove the existing top of the current door casing and install a 6″ plywood board.

  2. Select molding

    These are the pieces and types of molding used with this project. Measure the width of your doorway and mark where the cuts should be made on the molding pieces. The picture molding and the square edge molding should be measured and marked the exact width of the doorway. The bottom of the crown molding should also be measured and marked the exact width of the doorway.

  3. Cut molding

    Cut the picture molding and the square edge molding on the marks to the exact length of the doorway. With the crown mold, start the cut on the mark on the molding and cut the rest of the molding at a 45-degree angle. Next, cut a small piece of crown to wrap the molding around the side of the doorway.

  4. Attach molding

    The next step, once the molding is cut is to attach it to the piece of 1″x 6″ pine. Start with the crown molding and attach it to the top of the piece of pine as shown. Wrap the molding around and attach the smaller pieces on the sides. Next, attach the picture frame molding to the bottom of the 1″ x 6″ piece to disguise where the board meets the existing door frame. Lastly, attach the square edge molding directly underneath the piece of crown to give the illusion of an even bigger piece of crown molding. Make sure all molding is tightly secured and now you’re ready to paint.

  5. Caulk and paint

    After the molding is attached, caulk in any holes or gaps where the molding attaches to the door with paintable caulk. Then paint with two coats of gloss paint, allowing for drying time (as per the instructions on the paint) between coats.
