A majority of homeowners with hand tools can replace a window pane. In addition to a new pane, the following items are needed: latex glazing putty; pliers, glazier's points and the use of a heat gun to warm the old putty, if necessary. Before beginning, wear gloves and safety glasses as working with broken glass may cause injuries.

Begin by removing any remaining broken pieces of glass. It is best to use pliers however, a flathead may work equally. Utilize a wood chisel or putty knives to remove any remaining old putty around the frame and window sash. Work slowly and carefully and be careful not to break the current window sash. This should be done on a ladder, not the ground. Also, ensure that someone on the ground to ensure it is held steady.

Prepare the window frame to accommodate the new pane after you have removed the old glue. Measure the width and height of the opening for the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to a hardware or home center store to have a piece cut of glass that is in stock to the correct size. You can also cut the glass yourself if you have the tools you need.

After installing the glass Apply some caulking to the edge. This will make the glass weatherproof. Then, you can install a glazier's pointing on the frame's opposite side to secure the pane into its place. The points shouldn't be so tight that they create friction between the sash and frame however they should not be too loose.

Before applying the putty on the surface, knead thoroughly until it is soft and free from lumps. Then make it into pencil-sized strips. Apply the first strip to the corner of the frame. Work from one corner to the next and ensure that it is even and smooth.

Glazier's Points

The glazier’s points are small triangular pieces of steel which help to secure the glass to the frame without damaging the delicate surface. Learning how to use these hidden little helpers is easy and can save you money on professional installation or the cost of purchasing new glass.

Once the old putty and glazier's points are removed and the frame is thoroughly cleaned with a utility knife to eliminate any remaining residue. Lightly sand the wood in the rabbet grooves, if necessary, to smooth out rough areas. If you sand wood, protect it with painter’s tape to avoid accidental damage.

Write down the dimensions of the frame. These measurements can be taken to a home center or hardware store, and the new pane will be cut to a smaller size. This will ensure a secure fit and will allow room for expansion and contraction.

Place the new window in the frame and push it in place with your hand. Then use the point of your chisel or the back of the putty knife to pierce the glazier's points as illustrated in Figure 11. The glazier's points should sit flush against the top edge of the pane and the shoulders raised should be just below that lip.

Apply a thin layer of glazing compound to the rabbet grooves and edges of the glass. This will seal and protect the edges. Let it dry completely and cure.

Install the new window sash after the glazing compound has dried. First, saturate the wood with a thick coat of Linseed oil. This will prevent the new putty from drying out and cracking due to the moisture it absorbs. Apply this coat using a brush or the tip of your knife, then use the chisel or the back end of the knife to gently press the new sash and glazier's point into the grooves of the rabbet. Repeat this process in intervals of 10 inches around the frame.

Putty

A hurled baseball or an unintentional rock, or a falling branch can cause a window to crack or break. Most windows can be replaced by simply putting in a fresh piece. The glass is held into the position with a tiny metal clip, also known as a glazier's point and putty. This compound is also called glazing compound. Before installing a replacement double glazing windows pane, first remove the old one and clean up the area with a rag and an abrasive scraper that is a pull type or the wood chisel. Wear gloves and safety glasses when you work. If the window is attached to the frame, you'll need to make use of a heat gun to soften the adhesive prior to taking it off.

If you are planning to replace window pane the original sash, remove any pieces of molding that secure the old pane. Sand the sash until it's flat and ready to receive new caulk. After the sash has been re-installed and sanded, apply a fresh silicone caulk around the glass to ensure it won't leak or discolor over time.

Remove the glazing points from the rabbets. These are the grooves on the sash, which is where the glass is located. If they're hard to chisel, use the hand tool, such as a heatgun over them to soften first. If you're using a heat gun, make sure not to damage the railings of the sash or the sash itself by holding the tool too tightly.

Create a bed for your new pane after you have removed the old glaze and putty. Roll a rope with glazing compound between your fingers and make it around 1/2 inch thick. Place it into the rabbets, where the glass will be put. It's important that the glass sits on the putty in all places on both sides If you have to, lightly tap the glass into the rabbet using your thumb.

If the new pane has a crack then you can seal it with a solvent-based glue or silicone caulk prior pressing it into the sash. In other cases, you'll need to apply putty on the crack to form a tight seal and keep water out. After the putty has dried, wipe the oily film off of the glass and let it dry completely before painting.

When you are ready to begin with the removal of the window pane. Remove the metal glazing points that are attached to it. 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 that transforms into a solid moulded wedge that holds the window firmly in place and conceals the points.

Once you have the old pane taken away, clean up the surrounding frame and wood. Scrape off any paint and sand down the rabbet grooves where the glazing points were. They should be sanded to bare wood, to allow you to paint them the same shade as the rest of the frame. After sanding the wood you can apply a layer flax oil. This will help prolong the life of the frame.

Next, measure the width of the window's opening. You will need to take horizontal and vertical measurements of the entire opening and also the thickness of the old pane.

Bring these measurements to a hardware or home improvement store and have the glass 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. Use a putty knife to smear the putty evenly, making sure that there isn't an excessive amount of excess putty in the corners and along the edges. 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.
