It is a good idea to work on a sturdy ladder rather than on the ground and to have someone standing below the sash to help hold it in place.

Prepare the window frame to accommodate the new pane after you have removed the old putty. Measure the width and height of the opening in the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Bring these measurements to the nearest hardware store or home center, and get a piece of stock glass cut to size. You can cut the glass yourself if you have the appropriate tools.

After installing the glass Apply a small amount of caulking to the edge. This will make the glass weatherproof. Install a glazier’s point on both sides of the frame. This will secure the pane. The points should not be so tight that they create friction between the frame and sash but they shouldn't be too loose.

Before applying the putty to the surface, knead thoroughly until it becomes soft and free of lumps. Make it into pencil-sized strips. The first strip should be placed in the corner of the frame, working from one corner to the other to ensure it is even and smooth.

Glazier's Points

The glazier's points are small triangular pieces of metal which help to secure the glass to the frame without causing damage to the delicate surface. It's easy to learn how to use this secret tool and you can save money on the expense of an installation by a professional.

After the old putty as well as the glazier's points have been removed and the frame is thoroughly cleaned with a knife to remove any remaining residue. Lightly sand the wood into the rabbet grooves if needed to smooth rough areas. If you do sand your wood, make sure to 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 slightly smaller. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Place the new pane into the frame and push it in using your hands. Then, use the tip of your chisel or the back of the putty knife to make a tap on the glazier's points as shown in Figure 11. The glazier's points should be aligned with the top edge of your pane, and the shoulders should be just below that lip.

Apply a thin layer of glazing compound on the rabbet grooves as well as the edges of new glass. This will protect and seal the edges. Allow it to dry and cure completely.

Install the new window sash once the glazing compound has dried. The first step is to coat the wood with a thick layer of linseed. This will stop the new putty from taking up moisture and deteriorating and cracking with time. Apply the coat using a brush or the tip of your putty knife, then use the chisel or the back end from the putty knife to gently hammer the new sash and glazier's points into the grooves of the rabbet. Repeat this procedure every 10 inches along the perimeter of the frame.

Putty

A baseball thrown at you, an errant rock or a fallen branch can cause a window to crack or break. Luckily, most windows can be easily replaced by simply putting a brand new piece of glass in its place. The glass is held in position by a small metal clip, referred to as the glazier's point, and putty. This compound is also called glazing compound. Before installing a new pane, first get rid of the old one and clean the area using the help of a rag, the pull-type paint scraper or a wood chisel. Wear safety glasses and gloves while you do this work. If the window is secured to the frame, you'll need make use of a heat gun to soften the adhesive before cutting it loose.

If you're planning to install your original sash, remove the molding that supports the old pane. Sand the sash until it is flat and ready for new caulk. After the sash has been re-installed, apply a new silicone caulk to the glass to ensure that it will not leak or change color over time.

Take out the glazing points in the rabbets. These are the grooves in the sash, which is where the glass is. If they're difficult to work out, try holding the hand tool, such as a heat gun to soften them before you do. If you're using a heat gun, be cautious not to cause damage to the sash or its railings by using the tool too closely.

Make a bed for your new pane after you have removed the old glaze points and putty. Roll a rope of glazing compound between your fingers, and make it around 1/2 inch thick. Place it into the rabbets, where the glass will be placed. The glass must rest against the putty on both sides. If needed you want to tap your glass lightly into the rabbet with your thumb.

If the new pane is cracked then you can seal it with a solvent-based glass glue or silicone caulk prior pressing it into the sash. If the crack is not sealed, you'll need to apply putty to keep the water out. After the putty has dried remove the oily film from the glass and allow it to dry completely before you paint. If you paint before the putty is fully dry, it won't form an effective seal and could be leaking or discoloring in time.

These are tiny metal triangles that act as "nails" to hold the window within the frame. They are placed under a glaze putty or bead which hardens into a solid wedge which holds the wood frame firmly in position and hides the points.

After removing the old pane, clean the frame and wood. Scrape off any paint and sand down the rabbet grooves where the glazing points used to be. These should be sanded down to the point of being bare, so that you can paint them the same color as the rest of the frame. After sanding, apply a layer of flax oil on the wood that is not sanded down to extend the life of the frame.

Then, you need to measure the width of the window opening. It is necessary to measure the vertical and horizontal dimensions of the entire opening as well as the thickness. To determine the exact size of the new pane, subtract 1/8 inch from both measurements. This will also allow for expansion and contraction of the glass during seasons of changes. You can bring these measurements to a hardware or home improvement shop 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.
