Crown molding is a quick and easy way to instantly add a touch of elegance and sophistication to any room. Installing beautiful new crown molding in your home is a fun renovation project that both amateur and experienced DIYers are sure to love. While crown molding usually looks breathtaking, if you’re not careful with the installation, it can make a room look messy and unprofessional.

One of the trickiest parts of installing crown molding is cutting it properly, particularly when you’re dealing with inside corners. If you’re struggling with this aspect of the project, don’t worry–we’ve got you covered. In this post, we’ll show you how to cut crown molding inside corners like a pro. We’ll walk you through the necessary steps for both miter and coped cuts, as well as provide some tips to help you get the job done quickly and easily.

Tools and Materials Needed 

Before you start installing your new crown molding, you will need to gather all of the necessary tools and materials for the job. Here is a helpful list that you can use to get prepared:

  • Miter saw
  • Miter box or stand (optional)
  • Crown molding 
  • Tape measure 
  • Pencil 
  • Coping saw
  • Hammer and finish nails 
  • Caulking gun 
  • Wood filler or putty knife (optional) 

Step 1: Measuring the Inside Corner 

The first step when installing crown molding is to measure the inside corner of the wall. To do this, place the end of the tape measures flush against the wall at the corner. Mark where the other end meets and measure from there. Record this measurement on a piece of paper. You should also make sure to measure all other walls that are adjacent to the corner in order to get an accurate angle for cutting each piece of molding.  

Step 2: Making the Cuts 

Next, set up your miter saw on a worktable or on a miter saw stand. Place the piece of crown molding into the vice at an angle that corresponds to your measured inside corner wall angle (for example, if your measurement was 35 degrees, set your saw at 35 degrees). Cut one side of the molding at this angle. Repeat this process for both sides of each segment of crown molding to ensure a perfect fit once installed. 

Step 3: Coping the Joint 

For an even cleaner look, you can use a coping saw to cut one side of each piece of molding first and then join them together without any gaps. To do this, place both pieces across from each other in their angles as they would be when installed on the wall. Focusing on one side at a time, use the coping saw to cut away any excess material so that each piece fits together perfectly without overlapping.

Step 4: Installing The Molding

Once all the pieces have been cut accordingly and fitted together, install them onto each corresponding wall. Securely tack them in place using your hammer and finish nails. Make sure that the crown molding is firmly affixed to the walls with no visible gaps. Seal any nail holes with wood filler or putty if needed and then caulk around each joint where two pieces meet for an even cleaner look. And voilà—you now know how to cut and install crown molding inside corners like a pro!

Conclusion

Crown molding can take any room from dull and drab to elegant and stylish. While it can be tricky to learn how to properly cut and install crown molding inside corners, it’s not an impossible task. With the right tools and supplies, a little bit of patience, and a few easy steps, you’ll be able to tackle this project like a pro. Take your time and follow the steps outlined in this post and you’ll be amazed at the professional results you can achieve. With a few hours of your time and some careful attention to detail, you’ll have the beautiful crown molding of your dreams!
