How to Make Window Sills & Apron | Woodworking Finish Carpentry

Window sills can add character to the look and feel of a space. Follow Scott through the steps of building custom interior window sills to see how a window sill is designed and installed.

In this project, you will see how to build a custom window sill and apron (the trim below the windowsill) from standard lumber and trim. The steps include:
• checking for spacing
• buying material (5/4 or 1 1/4 inch thick boards)
• cutting the new windowsill to it's rough dimensions
• fitting the window sill to the wall
• determining the length of the horns on the window sill
• adding edge details to create a pleasing profile
• building an apron to install under the window sill
• gluing up the returns of the apron trim for detail on the ends
• trimming the apron
• installing the apron

Once the window sills (technically called window stools) and aprons were installed, the nail holes were patched and the parts were painted with no-VOC semi gloss paint.

Wow I wish I had watched this yesterday. I built my first 2 stools with aprons and then trimmed out the rest of the windows. Some of these tips would have saved me so much time!

The window sills look so much better. Great eye for detail.

Dude bravo! I need to do window trim, sills, and the stools to my upstairs windows. I started working with wood just a little bit for a whole 8 months lol. I’m as green as they come. I started acquiring tools, so I’m just with entry level Home Depot tools. I got the Dewalt 8 1:4” table saw that I love so far. And I have a buddy helping me

Amazing!! An age old craft that is sadly dying due to the mass production of engineered wood. I appreciate you for showing us that hand made, real wood craftsmanship is still alive.
