Take measurements of the width and height of the sash opening, Replace window pane subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to an hardware store or home center, and find a piece glass cut to size. Alternatively, you can cut the glass yourself, if you have the appropriate tools.

After putting in the new glass After installing the glass, apply a small amount of caulking on the edges. This will make the glass weatherproof. Then install a glazier's point on the frame's opposite side to secure the pane into place. The points shouldn't be too tight that they cause friction between the sash and the frame but they should not be too loose.

Before putting the putty on, make sure to knead it until it is smooth and free of lumps. Then you can roll it into pencil-sized strips. Apply the first strip to the corner of the frame, moving from one corner to another so that it is smooth and even.

Write down the dimensions of the frame. Take these dimensions to a hardware store or a home center and request that the new pane cut smaller than the frame's opening. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Insert the new pane into the frame and push it in with your hands. Use the point of the chisel, or the back of the putty knife to tap the glaziers' points as shown in Figure 11. The glazier's points should sit in line with the top edge of the pane and the shoulders raised should be just below that lip.

Fortunately, windows can be replaced by simply putting a brand new piece in the right place. The glass is held in place by a small metal clip, referred to as a glazier’s point and putty. This compound is also known as glazing compound. Remove the old pane and clean the area with a rag, a scraper that is a pull type or a wood chisel. Wear safety glasses and gloves while working. If the window is attached to the frame, you'll need use a heat gun to soften the adhesive before cutting it loose.

After the sash has been installed then, you can apply a silicone caulk over the glass. This will ensure that it doesn't leak over time or discolor.

Remove the glazing points from the rabbets. These are the grooves in the sash where the glass is. If they're hard to chisel out, you can try holding the hand tool, such as a heat gun to soften them up first. When using a heating tool, make sure to not damage the sash and its railings.

These are essentially small metal triangles that function as "nails" that keep the window in place in the wood frame. They are buried under a bead of glazing putty, which transforms into a solid formed wedge that secures the window in place and conceals the window's points.

After you have the old pane taken away Clean up the frame and wood. Scrape off any old paint, and sand the rabbet grooves where the glazing points were placed. These should be sanded to the point of being bare, so that you can paint them the same shade as the rest of the frame.

Next, measure the size of the window opening. You'll need to take horizontal and vertical measurements of the entire opening, as well as the thickness of the old pane.

Take these dimensions to a hardware or home improvement store and have a piece cut for you.

Now, it's time to bed the new window pane. To do this, place the pane inside the frame and move it around until a 1/16 inch of putty remains between the edge of the glass and the sash on all four sides.

When the putty dries, it can be painted with the same color as the frame to prevent water and air from leaking into the frame and causing fogging.
