My brother is a carpenter and just installed crown molding for us but according to pictures I have seen it seems to be upside down. It is standard crown molding and it was installed so the smaller cove is toward the ceiling and the thicker or wider more pronounced section on the wall. He says that all of the builders he works for have him install it this way. I also called some lumber stores and the majority of them have told me that the correct way to install it like my brother did. Is this the new way of installing crown molding?

like most moulding it can be installed anyway you want. it is not a law that it be installed a certain way.

i've seen chair rail used as door casing or had angles ripped on it and used as crown.

however, the most widely accepted way (and the only way i've ever seen it installed) is with the small cove down against the wall.

at first i would think that your brother was trying to bullsh*t you to cover up his mistake by saying that most of the people he does work for have him install it that way. i am a cabinet maker and trim carpenter and where i live, that is certainly not the case. however, if the lumberyards you called told you the same, either they don't know what they are talking about (lowe's/home depot have a reputation for that) or it really is the case in your area.

at any rate, if you are happy with it, let it go. if it really bugs you, have him redo it.

Thank you for your response. It is not that it looks that bad upside down but it really is bothering me because I wanted the job done properly. Unfortunately I think I am going to have to live with it because my brother insists that it is the correct way and I don't want to give him more money to redo the job.

Paul is absolutely right, you can put it any way you want of course... but the classical crown is a centries old design and the scotia at the bottom is made to balance the the ogee (wave) at the top. It creates the proper shadow & balance when installed the correct way.

Crown comes typically with 2 (spring) angles 45/45 and 52/38 if it is the more common 52/38 the longer height is always down the wall. You wouldn't want the crown to extend out onto the ceiling more than it comes down the wall.

If you or your brother wants to learn more on installing crown, or even more on the basics like "which way is up" visit my How to install crown molding site.

Thank you for responding to my post, Altereagle, and referring me to your website. It was actually after viewing your website about a week ago and seeing your instructions on how to install crown molding that caused me to realize that it was probably upside down. I have been researching this ever since. Since we don't want to tear it down, my husband and I think we will resolve this problem by adding a smaller molding or lattice at the bottom so more will be on the wall and it may appear more like we purposely had it installed upside down.

I bought a house last year and the crown molding in the LR and really fancy crown in the Dining room were annoying me for some unknown reason. Then I hired a guy to install crown in the bedrooms and when we both looked up on the hallway and he said "Do you like this profile?" I said "It's upside down right?" When you have it installed correctly it elegantly lifts the ceiling, if it is upside down, it just looks like trim.

That said, I just got back from a renovated Hilton Hotel with large crown moldings - all upside down. I wonder if it is some designer fad?

I'm irritated that I have to re-do all the other crown, but I can do it myself - fall project. Maybe I can salvage some for another project. It really looks stupid when you can see both the upside down and correctly installed molding.

Do you have pictures of the cove up and cove down to compare?

There is only one way to install crown or bed molding and it hankers back to classical Greek architecture. The cove or concave side is always down, the convex or rounded side is up.

I just purchased simple crown molding from Lowes, and if it is installed so the longer dimension goes down the wall, the upper curve is concave, not convex.

The proper way to install crown moulding is the simpler part of the profile faces up towards the ceiling. The easy way to remember is that it is installed the reverse of base moulding. You would not install your base moulding upside down. But many people are happy with either way.

The way I learned, is to put the detailed edge down

Wrong way.....the cove moulding part goes down.

Having the cove towards the ceiling or the wall are both common profiles these days. As others stated above, logic usually dictates that if the profile has finer details and lines on one edge, these are generally on the bottom, and if it is 52/38 ratio, the longer length on the wall gives more lift and support to the ceiling. However, a simple ogee on a 45/45 will often have the cove on top, especially if that is the wider or more prominent feature. Here is a link to Anderson McQuaid profiles (Cambridge, MA).

Whoops forgot to add link to above:

So, I am thinking of putting up crown molding over a bad tape job in my family room. I just want the simple stuff, and it is going into a room that had wood paneling. The corners of the wood paneling have small cove molding. If I put the crown the way I think is right side up, I will have a thin edge of the crown abutting a blunt cut edge of the vertical cove. If I put the crown “ upside down”, the edge is thicker and would make a clean seam along the top edge of the verticals. Is this an acceptable case for upside down?.
