How to Frame Windows

Framing a window may seem like a job for a professional. However, the hard part involves setting the window sash into the opening. Once that task is completed by a professional, the home owner can easily handle the remaining task of putting completing the look and security of the window by adding the framing.

Things You'll Need

• Level
• Saw
• Sandpaper
• Screwdriver
• Wood screws
• Wood glue
• Tape measure
• Wood putty
• Lumber to make framing sections

Instructions

1. Measure the top, bottom, and sides of the window casing. These measurements will serve as the basis for the lengths that the sections of lumber should be cut. Make sure that the top and bottom measurements overlap enough to account for the width of the lumber sections that will be used for the side pieces.

2. Cut the lumber into sections that will serve as the general frame for the window. Lightly sandpaper the ends of the cuts to smooth out the texture of the ends.

3. Apply the wood glue to the back of one of the side sections. Carefully align the section along the side of the window casing, making sure the top of the section is level with the top of the casing. Use the level to make sure the section is symmetrically balanced. Press the section into place, allowing the wood glue to begin bonding with the wall. Install one wood screw near the top of the section. Screw in another screw near the bottom. This will be enough to hold the section in place for now. Repeat the process with the other side section.

4. Place the top section into place using the same steps associated with the installation of the side sections. Take care to make sure the top section does not overlap the outside edge of the side sections. Install a wood screw at the extreme left and right portions of the top section.

5. Attach the bottom section using the same basic techniques applied with the top section. Before adding any more screws to the overall frame, use the level to make sure the angles are correct. Look the frame over for any small gaps. If any are found, these can be filled in with wood putty.

6. Cut a section of lumber to create a sill that will cover the slight space between the casing and the top of the bottom section of the frame. Secure with screws and wood glue. This will not be necessary if the window casing came with a sill already attached.

Tips & Warnings

• These steps will result in the creation of the simplest of frames. The wood used to create the frame can have a width and depth that the homeowner believes would make an attractive frame. It is also possible to purchase lengths of wood for window framing that is already mitered and only needs to be cut to size.

• Pay close attention to the measurements and also the cuts. This will eliminate the waste of time and materials.

• Always wear safety goggles when working with hand or power tools.
