This post is a long time coming. Like the saying goes “home takes time”. This is especially true when you are trying to document it all ha ha! Let’s dig in and see how to install crown molding.
Just last year we finished installing crown molding in the first floor bathroom, hallway, and guest room! It is so nice to look up and see it. The rooms look so finished ya know?
The top floor remains crown molding-less. We will get there. For now, I will bask in the crown molding glory that is my first floor.
If you are new here, we live in a 1929 Tudor Revival that was in fixer upper condition. Since purchasing the home, we’ve been non-stop with the renovation projects. We do a lot of DIY! One such DIY project is the crown molding.

Crown molding Make sure to let wood boards acclimate in your home for at least three days!
Flexible caulk– good for temperature fluctuation
Plastic wood wood filler -time dry indicator; goes on pink and dries neutral
10 inch blade 80 tooth (more teeth = finer cut)
Set up crown molding cutting jig.
At this point you have measured your walls at least twice and got the most accurate measurements. Next up is prepping to cut.
Oh were you wondering “what is a crown molding cutting jog?” It is the black plastic apparatus shown above. A crown molding cutting jig will help to cut the inside and outside corners correctly.
Cutting crown molding.
With the jig in place, you can cut the molding that will run to your corners.
Remember that the more detailed side is hung at the bottom.
If you have scarf joints to cut, you will remove the jig. And don’t forget to change the angle of the saw. We used a thirty degree angle.
What is a scarf joint? This is the seam where two pieces of crown molding meet along a wall.
Add supports to ease affixing to the ceiling and wall.
Use 1×4 poplar wood.
Measure the spring angle of the crown molding. Using this angle create a triangular template.
Cut a few triangles at once. An eight foot board would need three triangles.
The purpose of these triangles is to ensure the boards sit correctly against the ceiling and the wall.
Optional- instead of attaching the triangles to the crown molding directly, some people choose to attach to walls.
Nail boards in place.
Apply spring clamps if needed.
This step applies if you have a corner like the closet corner shown above.
The spring clamps prevent the boards from sliding out of place.
Cover the nail holes.
We like to use plastic wood with the color change property. You can see it goes on pink, then turns light brown when it is dry.
Sand the wood filler.
Excuse the blurriness- hubby was on a mission to finish!
That tube in the photo is a vacuum to catch as much dust as possible.
Caulk scarf joints.
Here is an up-close shot of a scarf joint with dried wood filler and the caulk being applied to the seam.
Depending on preference, wood filler can be used in the scarf joints.
Prime and paint.

Thanks so much! It’s like the icing on the cake. Have a great weekend!
What a fantastic job! It’s amazing how the addition of crown molding instantly elevates an interior space to feel more elegant and architecturally significant. Looks like a lot of work — but well worth the effort.
Thanks Carol! So sweet if you to say. Hope you have a great weekend 💗
Fantastic job and it looks so pretty. The little guy working is priceless!
Some great tips in this post. Your crown moulding looks stunning. You mentioned that you live in a ‘fixer upper’. I’ve seen photos of your house and I wonder when you stop calling it a fixer upper. It’s funny because I would call mine a fixer upper too but it’s nearly finished.
Thank you Carol! Haa that is such a great point. Hmm I guess I’m still in the fixer upper mode because our basement is still in progress and then the backlog of content I want to post lol.
Look great and your little helper is adorable!
Thank you! Hee hee he is a sweetie 🥰
Crown moulding really adds so much to a room! It looks amazing!
Thanks Karin! The room feels way more complete now. Have a wonderful day!
It looks great, Marie! I just finished installing crown molding on my main floor. It really adds that little extra, special touch 🙂
Thanks Marieza! You are a home improvement force to be reckoned with! It does feel like the cherry on top!
It looks so good Marie! We are going to start doing some home renovations this year. I much rather be in the garden! LOL!
Thanks Melba! What will you be doing? Your home looks perfect to me already. Ha ha I understand that, especially when weather is good!
Thanks for the informative post! This is on my to-do list, so I’m pinning for future reference! It looks so wonderful! Thanks, Donna
I’m so glad you found it helpful! Thanks for reading 😊 Hope you’re having a great week!
This looks fabulous! I love all of the step-by step instructions and photos. I had no idea about the triangle or using clamps. I think I might be able to do this myself!
Thank you so much! We love how it turned out. Happy Friday!
Great advise here. I tried crown molding around a tricky fireplace MANY years ago before power tools and how to videos. Didn’t go well. I think I could do it now.
Thank you! The age of Google & YouTube has really made DIY easier!! Happy Friday!
