Install a box valance to add character to a room or simply break up the monotony of a plain-looking wall with windows. Many types of pre-built valances will create the type of look you’re trying to achieve, but if you build a box valance yourself, you can create something really unique and interesting.

Whatever you decide, you will probably need someone to help you hold the valance during installation. Here is a handy step-by-step guide to help you install a box valance.

Step 1 - Measure for Your Valance

Accurately measure your window opening or curtain rods. Your valance should be about 3 inches wider than either side of the opening. This will ensure that your valance will properly open and that any drapes will be able to close over the window.

Step 2 - Install the L-Brackets

Attach the L-brackets to the wall square and level to the window opening. To do this properly, measure from the top of the ceiling down to the edge of the window opening where the L0brackets will be installed. Mark the top edge and bottom edge of the L-bracket so that you can properly align them later. Repeat the process for the other side.

Locate a stud or wall brace for support. Use your power drill or electric screwdriver to attach the L-brackets to the wall with wood screws. Then repeat the process for the other side.

Step 3 - Attach the Box Valance

Have someone help you hold the valance in place. Measure the screw holes on the L-brackets and pre-drill holes in the valance according to those measurements. By pre-drilling holes, you'll be able to quickly and safely screw the wood screws into the valance through the L-brackets.

Insert one screw on one side and then another on the other side to help support the weight of the box valance. Then shore up the attachment by inserting additional screws.
