Crown Moulding 101: Installation

Crown moulding installation can be tricky, which is why we highly recommend leaving it’s installation to the pros. But if you insist on installing crown moulding yourself, we have a few tips for you.

  • You will need to cut the crown moulding. Be sure to measure and mark the crown moulding prior to cutting. We also recommend using a power miter saw to achieve more precise cuts. Place the piece upside down at a 45 degree angle throughout the process. The top edge, which meets the ceiling, should be flat against the horizontal saw table. The bottom edge will rest against the vertical back fence of the saw.

  • Crown moulding won't reach the entire length of the wall. To solve the problem, you can stitch two straight pieces together with a scarf joint. Cut the left piece at 45 degrees, as if cutting it to fit into the left side of an inside corner. Cut the adjacent, right-hand piece as if cutting the right side of an outside corner. The two pieces will butt neatly together in the center of the wall.

Crown Moulding 101: Maintaining Your Moulding

Maintaining your crown moulding is as easy as cleaning it!

  • Use a long-handled duster or a vacuum with extendable attachments to do an initial sweep of your crown mouldings. This will help capture or clear away a significant amount of dust and debris.

  • A gentle, homemade solution can be used to polish your moldings. Some popular mixes include water and vinegar or water and Castile Soap. Gently wipe down your moldings with a clean microfiber cloth, rag, or sponge that has been dipped in the solution and voila! Bye bye, stubborn dirt and spots. Remember to also bear in mind your moulding’s individual composition. For example, you may prefer to switch to a wood cleanser for some wooden moldings, or avoid certain cleaning agents (like alcohol or ammonia) on delicate painted surfaces.
