Thanks for taking the time! I just want to touch on a couple things here that may help with the process.

I start with my Stanley tape measure to get our dimensions of the Window Sill and Apron.

Opening (from drywall to drywall) + 3” = WINDOW SILL

Window Sill - 1” = APRON

frame of window to finished edge of drywall + 1 1/2” = WINDOW SILL DEPTH


Next, using my Dewalt 12” Miter Saw I cut the length of my 1x8 material for the window sill. Then cut the length of my apron using a 15 degree cut on the ends. Like I said this is the specifications that DR HORTON requires us to do.

Then using the Dewalt 10” table saw I rip my piece to 6 3/4” or overall depth for this particular window. Real easy for me to set the “fence” of the table saw into position and just lock it in. Make sure when you are using a table saw you always maintain pressure on the material pushing it down and to the “fence”. ALWAYS ALWAYS ALWAYS hold pressure to the piece between the blade and the “fence”, if not the material may bind and shoot back at you!!!! Your window WILL most likely be different dimensions so please use my easy math to get yours RIGHT.

Next, Routing our material. Don’t be afraid of this step! Yes it requires the tool, which in my case is the Dewalt 20v Router. Just follow the instructions to set the router bit in the tool correctly and set the depth. Maybe try on a scrap piece a couple times to get your profile right. Listen and watch this part of the video if you need good explanation of how to hold and what to focus on while using the tool.

On to scribing the Window Sill. I use a speed square to help with verifying my pencil lines and determining if the drywall is square to the window. Remember 3” larger so split the difference 1 1/2” each side for the “ears”. Once you get the window sill centered continue to hold pressure so it doesn’t move while you figure out the angles. Draw your lines and cut out the back corner pieces, I use a Dewalt 20V Jigsaw to make it easy.

Installing the Window Sill does require some focus, but we can DO IT! DO IT NOW! Start with getting your reveal in one corner of the sill and then level that side. Move across the sill to match your reveal against the window until you get to the other side. Level that side as well with a handy Stabila speed level. Then with a larger level place on the front of the sill and verify the front is level and straight. I use a screwdriver to pry and hold my material when shooting any nails so my material doesn’t move when firing the Metabo 2 1/2” 16 ga. nail gun. The apron is very easy in our case here, just center it under the window sill and nail it snug up to the bottom. After caulking and paint your new Window Sill will be ready to go!
