You guys! Today’s project is easily one of our favorite before and after’s to date! We recently drove to our sister’s house in Houston to crash it and give it a little shanty makeover. We have already shared so many of the other projects with you, and today we are showing you how we gave her dining room window a serious update! Many of you may have half circle windows. They can not only be difficult to keep sunlight and heat out of, but they also tend to lock the room they are in into a certain look and era. There are shades out there to install such as sunburst shades or a cellular shade but we love the look of casement windows and thought we could change the look of her dining room with a quick DIY update! We decided to take care of that with a little trim… Well, actually it was a whole lot of trim! Just click the Play Button below to watch!
Before you all ask, from the outside of the house, the top window now looks white. You can definitely add something to the back of these boards before attaching if you want a different look, but we love the simplicity of the white!
Now, each half moon window in every home is going to be a different type of window. We will show you how we achieved the look with her arch windows setup, but you will likely have to modify it a bit to work with yours. The very first thing we did was remove the existing window stool and replace it with new boards that were flush with the edge of the wall. We used our table saws to get them the exact width we needed. We are using primed white pine boards for the whole thing.
We attached the new stool pieces using wood glue and 2″ nails with our Ryobi 16G Finish Nailer.
Next, we created the “L” piece, or apron that runs under the window. This is a 1×4 piece with a 1×2 piece that we attached to one end. To get the measurement of the 1×4 piece, we measured the very end and inside of each side window to get the overall width of the whole window. Then we added 7″ to that number since we are going to be adding a 1×4 going vertically on each end in a later step. So, measure this number and then add 7″.
The 1×2 piece will be 1.5″ longer on each end and stick off evenly. We attached those together using wood glue and 1.25″ brad nails with our Ryobi 18G brad nailer. Once those were attached together, we placed in flush with the new stool piece and attached it to the wall using the finish nailer with 2″ nails again. The apron will sit evenly under the window.
Next, we moved up top! This is a step that some of you may not need depending on your setup. Our half circle window was joined to our lower windows, so we needed to create a head jamb for the top of the window to separate the two. We first measured this spot…
Then, we cut a board to fit that space…
To attach it, we added 3/4″ pocket holes using our Kreg Jig to the top of this board where nobody will ever see the holes. Then, we attached it to the wall on each side using 1.25″ pocket hole screws.
We worked our way up from that point. We used a 1×10 board and a 1×2 board to create the first piece for the header of this window trim. We cut the 1×10 the same length as the 1×4 we used to create the apron, and we again made the 1×2 board 1.5″ longer on each side. We attached the 1×2 to the 1×10 using wood glue and brad nails, and then set the bottom of it flush with the inside top of the windows and attached it to the wall using 2″ Spaz screws into the wall studs.
We built the rest of the header next. This is a 1×8 board, cut the same length as the apron with a 1×2 board attached to each end. The 1×2 boards are the same measurement as the previous 1×2 boards.
We attached them using wood glue and brad nails, and then attached the entire piece to the wall using 2″ Spax screws.
From there, we moved on to our vertical trim pieces. The outside two boards are 1×4. We grabbed this measurement and cut them to size.
We attached them using 2″ finish nails.
For the inside trim pieces, we grabbed this measurement. We then used a table saw to cut 1×6 boards down to the exact width we needed. The were the same length as the two outside trim pieces, and we also attached these using 2″ nails.
That’s it for trim! Now comes the most important part…. The caulk and wood filler! My stepdad once told me… Caulk and Paint make a carpenter what he ain’t. I love it! It’s so true! And it really comes into play when working with walls that aren’t totally square and flush. We filled all of seams with caulk, and filled the nail holes with wood filler. After that dried, we put our sister to work painting it to match the rest of the room! Now, let’s look at that before and after again! Hide your eyes… Here is the first before!
Here it is right before we got our hands on it!
And here she is now… Heck yes! Just removing the blinds added so much natural light to her space! We decided to get rid of the blinds and just use curtains for privacy
What about that guys?!
And a shot of the whole room….

I love this! I don’t have arched windows but I love the idea of the added trim above the windows, might steal this idea. Great job!
Is there anyway I can see what this looks like from the outside? I have four windows like this!
I’d like to see the outside too. I love the idea and would like to cover my arch but not sure if it looks weird from the outside.
You shouldn’t feel this entitled to their time and effort, especially when they are providing free content and building plans.
YES!!! Agreed!! The entitlement and audacity of some is blowing my mind.
Thank you, ladies!!!
I loved the arched window. It only needed a better window treatment.
Did you insulate the windows behind those wood slays inside the house before boarding it up? Do you worry about moisture build up from the window to the boards inside?
Sorry I think it looks like a second thought. The trim makes no sense
