Often when a window is damaged, it is only an easily replaceable pane of glass that breaks. However, sometimes, the window itself (the wooden frame) is also broken. Simple, non-opening windows are easily made for replacement. These sort of windows are often long, elegant windows alongside the front door, or small, high-set windows in a laundry room or bathroom. But they can be found anywhere in the house.
Cut the 2x2s to the necessary length and width of your window. For example if you need a window 6 inches by 20 inches, cut two boards 6 inches long and two boards 20 inches long.
Cut the corners of each board to have a 45-degree angle so they will match up to create your window frame. Just think of how a picture frame comes together.
Measure and mark the exact centre of the board. This is where you will have a glass inset. Then carefully rout out the centre line to a depth of 1/4- to 1/2-inch deep. Do this for all four boards.
Drill pilot holes in the corners along the slant sides to match up when two sides are placed together. For added security, drill two sets of these holes per corner. NOTE: Likewise, when placed together, the routed-out grooves should match up.
Squeeze in a drop of wood glue into the hole (or pair of holes) on one corner and insert the dowel pin(s) half way. Then squeeze in glue into the holes of the matching corner piece and fit it over the exposed dowel pin(s). The two pieces (a side and edge) should fit together tightly, forming a 90-degree angle.
Repeat to fit the the other side onto the window frame, leaving the bottom edge open.
Insert the pre-cut piece of glass.
Fit the bottom of the window frame, using the glue and dowel pins to match it up to the frame's two sides.
Caulk around the glass.
Finish the window frame by staining or painting it.
