Window Sills & Heads: How To Frame A Window

To frame a window, you’ll need care, precision, and an absolute attention to detail. A poorly-installed or weakly-framed window can lead to water damage and even health hazards if a draft sneaks in, which is why it’s so important to choose the right kind of window sill and know what you’re doing when you position it.

But don’t fret, it can be done! Here are a few basic steps to rolling up your sleeves and framing your own window.
1: Measure Your Window Space
How big is your actual window? How large will your window sills need to be? Make sure your measurements are exact, and then add two inches to each dimension. For example, if your space is 40″x46″, your final measurements will be 42″x48″. Whether you are fitting the window yourself or hiring someone to fit it for you, measurements are often considered the most important part as if they do not fit correctly gaps may occur or the window sill may not fit.
2: Use Quality Materials
Ensure you use high quality materials that will last through both time and weathering. Natural Stone is a good place to start be it Granite, Limestone or Sandstone. There natural window sill materials are not expensive and will result in long lasting window sills and also be aesthetically pleasing
3: Replace Old Studs
This will require a power saw and a willingness to get your hands dusty. To remove old studs, open up the drywall and see where they mark the window’s placement, then ease them out and stick in fresh ones according to the specifications of your new window sill. Add an additional three inches to accommodate future errors.
Tip: Make sure you’re using king, jack and trimmer studs as their packages instruct! Each have their own unique functions within your construction, and the integrity of your window sills depend on them being used correctly.
4: Install Your Header
Cut two window sill plates that equal the length of your window. Nail them to your studs and to each other using a carpenter’s level to ensure a balanced hang. You should now be looking at a horizontal beam running across the top of your window with your sill plates securely attached.
5: Install Your Base
Repeat the previous step with the bottom of your window, adding at least three cripple studs to support the weight of your future window sills. Ideally, the studs will go at both ends and then the middle of your frame
