Once you have removed all of the old putty, it is time to prepare the window frame to fit the new pane. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of the width and height. These measurements can be taken to a hardware or home center store to get a piece cut of glass that is in stock to the correct size. You can also cut the glass yourself, if you have the appropriate tools.

After putting the new pane in place, run a small bead of caulking around the edge to ensure it is weatherproof. Install a glazier's point on both sides of the frame. This will help secure the pane. The points should not be tight enough to cause friction between the frame and sash however they should not be loose.

Before putting the putty on, make sure to knead it until it is soft and free of lumps. Then make it into pencil-sized strips. Place the first strip in the corner of the frame, moving from one corner to the other so that it is smooth and even.

After you're done, the points should be in line with the top edge of the pane and the shoulders of the points should be below the lip of the rabbet groove.

Apply a thin layer of glazing compound on the edges of the glass that has been made and into the rabbet grooves to seal and protect them. Let it dry and cure fully.

Once the glazing compound has dried it's time to put in the new window sash. The first step is to coat the wood with a thick layer of linseed. This will prevent the new putty from drying out and cracking when it absorbs moisture. Apply this coat using a brush or the tip of your putty knife, and then use the chisel, or the back end of the knife to gently hammer in the new sash and glazier's point into the grooves of the rabbet. Repeat this procedure every 10 inches around the frame's perimeter.

Putty

A hurled baseball or a rock that is errant or a falling branch can cause a window to break or crack. Fortunately, the majority of windows can be repaired by simply putting a new piece in the right place. The glass is held into position by a small metal clip, referred to as a glazier’s point and putty. This compound is also called glazing compound. Before you install a new pane, first get rid of the old one and clean the area using an abrasive and a pull-type paint scraper or the wood chisel. Wear protective glasses and gloves when working. If the window is secured to the frame, you'll need to use a heat gun to soften the adhesive before prying it free.

After the sash has been re-installed and sanded, apply a fresh silicone caulk around the glass to ensure it will not leak or change color over time.

Remove the glazing points in the rabbets. These are the grooves on the sash, which is where the glass is located. If they're difficult to cut out, try holding an instrument like a heat gun to soften them up first. When using a heated tool, be sure to not scratch the sash's railings and sash.

Once the old points of glazing and putty have been removed prepare a bed for the new pane. Roll a piece of glazing compound between your hands, forming it to be about 1/2-inch thick. Then, push it into the rabbets, where the glass will sit. It's important that the glass rests against the putty on each side If you have to tap it, gently press the glass into the rabbet with your thumb.

If the new pane has a crack then you can seal it with a solvent-based glass glue or silicone caulk prior pressing it into the sash. If not, you'll have to putty over the crack to create a tight seal and keep water out. After the putty has dried clean the oily film from the glass and allow it to dry completely before painting.

When you're ready to start taking off the old window pane by removing the glazing points made of metal that are connected to it. These are essentially small metal triangles which function as "nails" that hold the window in place in the wood frame. They are placed under a bead or glazing glue that hardens to an unbreakable wedge that holds the frame in place and conceals the edges.

After removing the old pane, clean the frame and the wood. Scrape off any paint that has been used, and sand the rabbet grooves in which the glazing points were. Sand them down to bare wood surfaces, so that you can paint the frames with the same color. After sanding, apply a coat of flax oil on the bare wood to help extend its lifespan.

Next, measure the dimensions of the window opening. You'll need to take horizontal and vertical measurements of the entire opening, and also the thickness of the old pane. To determine the exact size of the new pane subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. Take these measurements to your local hardware or home improvement store and ask them to cut you a piece cut for you.

Now, it's time to bed the new window pane.

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.
