Crown Molding

In the eyes of many would-be interior designers, crown molding is an outdated style relic to be forgotten. However, modern crown molding ideas and designs could be making a comeback, with more options and materials to choose from.


The term crown molding (also spelled crown moulding) typically refers to a decorative trim or molding that is installed over the joints between the interior walls of a room and the ceiling. Crown molding is also commonly installed to help accessorize the tops of windows and entryways, and to fill in the spaces above kitchen cabinets, known as soffits. Traditionally, crown molding is made of plaster or wood and can be quite ornamental, often with multiple layers and elaborate designs. Modern crown molding is often formed from composite wood and/or plastic materials, and comes in a range of styles, designs, and prices. There are also foam crown molding options for simple DIY crown molding projects, designed with easy installation and cost savings in mind.

Crown Molding Installation

Knowing how to install crown molding takes a bit of knowledge and skill, especially when working with plaster or wood. However, there are easier options available, which might just help you cut some corners:

  • Learning how to cut crown molding can be a bit tricky because of the angles, especially the corners.  However, with the right tools, like a miter saw or a coping saw, and a well designed crown molding jig, you’ll be cutting crown molding like a pro.
  • If you’re looking for an easier way to install crown molding, look no further than foam crown molding. Foam crown molding is an excellent option for anyone looking to take on a DIY crown molding project. Cheaper and easier than wood, plaster, and composites, foam crown molding may be a suitable budget friendly option.
