Allow me to confess something- The first time I came across installing crown molding, I thought it was as exciting as watching grass grow. It was frustrating and antagonizing- I mean, just thinking about getting the angles right!

I truly considered not learning much about installing crown molding. After all, someone more technically qualified could always do it for me anyway.  So if you have any apprehension, believe me I understand. 

Since then, however, I have found that crown molding installation can be as easy as tying your shoes. More than that, it can actually be quite a fun task!

To help you see what I mean, this article will give you the tips and tricks to make installing crown molding an achievable and doable task.

Tips in getting good quality molding

#1. To achieve a good installation job, select good quality molding in a style that fits the layout of the room. Our crown molding is made from high quality polyurethane that is pliant, easy to install and durable. It is resistant to moisture and temperature changes and will be great for any room including the bathroom and kitchen.

#2. Consider aspects such as the length of the wall and ceiling height when choosing the crown molding. For tall ceilings that deserve a wide, ostentatious molding, try this impeccable piece with a detailed surface.  For a less elaborate face, consider this plain but classic style.


Tips in preparation 

#3. Take linear measurements of the walls to determine the amount of crown molding that will be needed. To be sure of the measurement, measure each length twice or thrice if necessary. 

In an even, square room, getting the length could simply be as easy as measuring one length and then multiplying it by 4. For a rectangular room, you could measure one length and one width and multiply each of these by two. 

While this will undoubtedly be faster, consider that sometimes opposite walls are not built exactly symmetrically and may vary slightly in length. Measuring each wall individually is more likely to give a more accurate indication of the crown molding needed.

#4. Accommodate for any mistakes and molding lost when making cuts by purchasing more molding than the actual room measurements.

Tips when cutting the corners

When putting crown molding atop a wall, the molding sits at an angle between the wall and the ceiling. This complicates cutting slightly. Moreover, the walls are not always straight or perfectly square. 

To cut corners of your crown molding, use:

  • A coping saw for inside corners

  • A miter saw for outside corners

A coping saw is a type of bow saw used in carpentry to cut interior cut outs and delicate external shapes. It may be considered better than a miter saw because a coped joint is tighter than a mitered joint.

This notwithstanding, the miter saw has its strengths. It is a powered saw used to cut miters and cross cuts accurately. It will be ideal when making outside corner mitered joints and scarf joints for two pieces of molding along the same length of wall.

When coping:


#5. Use only one hand. The thumb should be on the opposite side of the rest of the fingers on the handle, similar to picking up a mobile phone. That way, the hand never moves but you can rotate the saw depending on whether you are undercutting or overcutting. 

#6. Slightly marking the crown molding on the outside edge with a pencil helps to accurately cut the molding. Keep the coping saw at a slight angle while firmly holding the handle to provide room so that the cutting pieces don’t bump.

#7. When cutting, use a clamp to hold the crown molding firmly in position. Always start with cutting the straights of the molding and then do the cope. Should the trim not be as smooth as desired, use a file/ sanding paper to smoothen it though caulk will hide such imperfections.

#8. Practice the cuts on spare pieces of trim and fit them together to confirm that they form a snug fit before making the cuts on the actual molding. 

When mitering: 

Mitering comes very handy in putting up crown molding on kitchen cabinets or when working with smaller pieces around columns.

#9. When cutting a molding on the miter saw, position the trim upside down and backward so that the miter fence acts as the wall and the miter base acts as the ceiling. When working, work in one direction starting with the long wall.

#10. When you work to the right, you will make most of your 45 degree cuts with the miter saw set to the left and vice versa. For outside corners, position the molding upside down and face up in the miter fence acting as the wall and the miter base as the ceiling.

#11. Use an angle gauge to check the angles for out of square walls so that you can cut and install trims accordingly and accurately.

#12. For effectiveness, leaving the end of the first joint loose until the second one is up, ready to be adjusted and secured by nails allows the corner to be rolled and attuned until it fits. 

Tips in installation

#13. Start with the least conspicuous wall or the one furthest from the door. It should preferably also be the longest wall so you get it out of the way.

#14. Work in one direction so it will be easier to make the cuts and also avoid confusion. The final piece of molding will probably have two coped ends so it fits snugly.

#15. Imperfection is not an unforgivable crime. Be liberal with caulk to hide any uneven surfaces or gaps. 


As frustrating as I first found crown molding installation to be, I have come to appreciate this royal piece of trim and enjoy the ways in which it transforms a room. With these tips in mind, the task of installation is all the more pleasant. 

Start by getting high quality molding and the necessary tools for the corners. Make the cuts as accurate as possible by practicing with spare trim pieces. Work in one direction to make the work faster and smoother. In case of any mishaps, use caulk to hide the blemishes.
