How to Add a Window Casing
Window casing refers to the decorative trim or molding around a window. Casing is basically a big picture frame your window sits inside, consisting of four measured pieces, cut with a miter saw and fit together. Casing can be created from materials such as bamboo, hardwood veneer, pressboard or extruded plastic, but the most popular is wood. Adding window casing to your windows is relatively easy if you follow the correct procedures.

1
Remove any old window casing or trim from your window, using a pry bar. Measure the area around your window, using a tape measure. Mark the corners where the inside of the casing will rest with a pencil for easier installation later.
-
2
Fill any gaps around the window jamb with fiberglass insulation. Avoid using expanding foam products if possible to minimize mess.

3
Mark the lengths you will cut on the pieces of window casing with a pencil. Use a speed square to draw 45-degree angles to make it easy to cut.
-
4
Cut the four pieces of trim with a miter saw. Pay attention to the lengths and angles so the casing will fit together properly.
-
5
Lay the four pieces of cut trim on the floor. Place them together as they will be in the window. Use a power nailer with brad nails and nail together at the corners. Use two nails for each corner.
-
6
Hold the casing in place over the window. Use the window markings as a guide. If the casing is heavy or awkward, find someone to help hold it in place.
-
7
Insert two nails on either side at the top of the casing to secure it in the window. Places nails around the casing every 8 to 12 inches, using the nailer.

Tips & Warnings
When nailing the frame together on the floor, use a piece of plywood to raise each corner off the ground slightly as you nail it.
