Decorative exterior wood shutters add architectural detail to the facade of your house. They frame the windows and add accent color to your walls. Shutters must be built with treated lumber since they are exposed to the elements. Keeping your shutter project simple is a good way to ensure success. The simplest form of shutters to start with are board and batten shutters. These shutters feature three vertical pieces, known as the boards, held together by two horizontal pieces, known as battens.

Board and batten shutters provide architectural detail.

Step 1

Measure the height of your windows. Cut three pieces of 5/4-by-6-inch round edge treated decking 4 inches taller than your window using a miter saw. This is a standard decking board traditionally used for backyard decks. Cut two pieces of 2-by-4 treated lumber 17 1/2 inches long.

Step 2

Measure from both ends of each of the decking boards and use a square to mark across the face, 6 inches from the end. Glue and clamp the battens to the face of two of the boards with C clamps so that the bottom edge of the top batten is even with the top line on both boards and the bottom batten is even with the bottom line. Align the ends of the battens with the outside edges of the boards.

Step 3

Turn the shutter over so that the boards are on top and drive one 2 1/4-inch treated deck screw through the back of each board where it intersects with each batten to attach them. Clamp the remaining board centered between the other two with the top and bottom flush with the first two boards. Repeat this for the second shutter.

Step 4

Drill a 1/8-inch hole 3 inches in from each side of each shutter, through each batten, centered in the batten. Position the shutters against the wall 2 inches out from each side of the window and use a level to adjust them for level. Drive a 3-inch treated deck screw through each of the four holes to mount the shutters to the wall.
