How to – Window Treatments for Transom Windows

Window Treatments for transom windows are truly one of the most challenging types of windows I come across.

Why? It’s not what you think.

It is not because they all that hard to design window treatments for. It’s because I find most homeowners have this little voice in their head telling them the window treatments…“must be placed between the transom window and the lower window”.

I’m not sure why people get emotionally attached to the top windows….I mean when there isn’t a transom window it is easily understood by everyone that the treatment wouldn’t go anywhere but above the top section of any window. So why is it when there is a transom window the inclination is so prevalent to divide the windows and place the treatments between them?

Because of a sliver of molding or a small section of wall….?

This concept is so commonly believed and so dearly clung to that I often wonder if there is some ancient book that secretly gets passed from one homeowner to another that admonishes them:

Thou shalt not put roman shades, drapes, blinds or any other style of window treatment on sacred transom windows

Old Book

It’s odd and a little funny too, because usually when I make any sort of suggestion about window treatment design it’s met with “Oh, yes, that’s a nice idea, I like that, tell me more”. But with transoms, 7 times out of 10, I hear “Oh, no I can’t cover the transom, we really like that window and the light, my husband will say no too.”

And my personal favorite:
“It won’t look right”.

I don’t know, call me crazy but which looks better to you?

I’m so used to it by now, so I tread lightly when I first start suggesting ideas. However sometimes I do meet a customer like Sharon S. in Madison, NJ who was happy to listen to new ideas right off the bat and to at least explore the idea of not dividing the windows. She has become one of my favorite customers not only because she is always open to new ideas in window design but because she is just so darn fun and pleasant to work with. I enjoy our visits immensely and have always been proud of the work we have created together.

Here is the before of Sharon’s family room:


And the After:


The only thing different is the window treatment and 1 chair in the left corner. Otherwise, same lovely room, same gorgeous area rug, the same tasteful accessories.
But, big change.

Do you agree?

By placing the drapery rod above the transom window we accomplish two things, we draw the eye up and we create a sort of lightweight valance effect. As a bonus, the rods visually connect the two windows to each other. The drapery panels, placed on the outsides only, anchor the room and create a compelling focal point, immediately grabbing your attention when entering the room.

And lastly, what else do you also notice?

Yes!! The light still streams in washing over the room, the view outdoors invites you to look further and rather than detracting from the room design by working above the transom, the room actually springs to life!

Take a look at a few more examples and tell me if you can see my point:

    Hi , we moved into a ranch style house that has 3 transom windows and casement style ! 2 flank the fireplace in family room and one is next to other on opposite wall. House is very hot with sun beating in all day it’s like a greenhouse . This is not our forever home so we don’t want to spend a lot . I want it to look nice . Hubby wants it to cool down . What are our options ? 
    I could send pics if you want . 
    Shades that are custom are not something I want to spend in this house .

    We were going to the same thing as you spoke about. Don’t cover the transom windows. I do think it looks better in 99% of your examples. What if your transom is narrow above the window? I can send a picture. Thanks for the article and any advise on the picture I send you. Glen

    My builder won’t add the transom windows to the living room because he said it’s too late because windows have been ordered and they’re in production, can I add transom windows after the house it built and finished? If so, how much would that cost approximately? is it worth it?

    I love how you mentioned that you can place drapery rods above windows to draw the eye up and create a valance effect. The new home I am looking to buy has a lot of different types of windows. This article made me realize it would be best to hire a professional to treat my windows.

      Hi Vivian, thank you for sharing! Yes, windows are trickier than most people might think, especially when the windows are unique shapes and sizes! A professional can help create a beautiful space without taking away from the uniqueness of the windows. Are you in the Tri-State area? We can help!

    I am decorating my son”s new home. He has transom windows and a view of the mountains. He wants
    drapery panels on each side, but not to cover the transom. The measurements for the panels are 100 x 100 and he wants them gently puddled.
    so i m thinking 6-8 in puddles. he also has 10 ft. ceilings. Can I do the drapery panels this way? There are blinds on the
    bottom windows where the panels would go. Thank You. Diana

    I have transom windows throughout my whole house. One in particular that I’m not sure about is in the eating area (open to the kitchen). On the same wall as the large windows is a door, which has a transom window over it. How would you put window treatments?
