Then, use a wooden chisel or putty knife take the remainder of the old putty from around the frame and the sash. Be careful not to break the window sash. Be careful and slow. It is a good idea to do this using a sturdy ladder rather than on the ground, and to place someone on the sash in order to help hold it steady.

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

After putting in the new pane After installing the new pane, apply a small amount of caulking along the edge to seal it against weather. Install a glazier's point on both sides of the frame. This will help secure the pane. The points shouldn't be so tight that they cause friction between the frame and sash However, they should not be loose.

Before applying the putty on the surface, you must knead it thoroughly until it is soft and free of 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, making sure it is even and smooth.

Glazier's Points

The glazier's points are the small triangular pieces that help secure glass into a window frame without damaging or scratching the delicate surface. It's simple to learn how to use this secret tool, and you'll save money on the cost of a professional installation.

Once the old putty and the glazier's point are gone, thoroughly clean the frame with a knife to get rid of any remaining traces. Lightly sand the frame in the rabbet grooves if needed to smooth rough areas. If you do sand the wood, make sure to protect it with painter's tape to avoid accidental damage.

Note down the dimensions of the frame. Take these dimensions to a hardware store or home center and have the new pane made slightly smaller than the frame's opening. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new window in the frame and press it in place with your hand. Use the chisel's point, or the back of the putty knife to tap in the glazier's points, as shown in Figure 11. The glazier's point should be flush against the top edge of your pane and the shoulders raised should be just below the lip.

Apply a thin layer of glazing compound on the rabbet grooves as well as the 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. The first step is to coat the wood with a thick coat of linseed oil. This will keep the new putty from taking up the moisture and drying out and cracking with time. Apply the coating using a brush this coat, or even the tip of the blade. Then, use the chisel on the back of the putty tool or the back of the putty handle to gently smash the new sash or glazier's point into grooves of the rabbet.

Putty

A baseball thrown at you, an errant rock or falling branch could cause a window to crack or break. Most windows can be repaired easily by simply putting in a fresh piece. The glass is held in place by a small metal clip, also known as the glazier's point, and putty. This compound is also known as glazing compound. Remove the old pane and clean the area with an abrasive, scraper that is a pull type or a wood chisel. Wear safety glasses and gloves when working. If the window is secured to the frame, you'll have to employ a heat gun in order to soften the adhesive before prying it free.

If you are planning to install your original sash, you must remove the molding that supports the old pane. Then, sand the sash to ensure it's level and ready for a new caulk. After the sash has been installed it is possible to 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 and the grooves in the sash where the glass is. If they are hard to chisel, hold a hand tool such as a heatgun over them for a few minutes to soften them. If you're using a heating gun, be careful not to cause damage to the sash or its railings by placing the tool too closely.

Prepare the bed for your new pane after removing the old glaze and putty. Roll a rope of glazing compound between your hands, shaping it into a 1/2-inch thick. Place it into the rabbets, where the glass will be placed. The glass should rest against the putty on both sides. If you need to gently tap your glass into the rabbet with your thumb.

If the new pane is damaged, you can use a silicone caulk or a glass glue that is based on solvents to fill in the crack before pressing it in the sash. Otherwise, you'll need to putty over the crack to create an airtight seal and keep water out. Once the putty is dry, wipe the oily film from the glass and let it dry completely before you paint.

Paint

If you've had a broken window pane, you may be concerned about the expense of replacing it. It's true that replacing a single pane of glass doesn't need to be costly when you do it on your own. In fact, even a double-pane window can be replaced at less than the cost of an expert.

First, if you're working on a large window, make sure that it is securely fastened to the frame. This job can be made relatively simple and fast with the appropriate tools and techniques.

When you are ready to start, remove the old window pane. Remove the glazing points made of metal that are attached to it. They are basically tiny metal triangles that act as "nails" which hold the window in within the frame of wood. They are placed under a glaze putty or bead that sets to form a solid wedge that holds the wood frame securely in place and hides the sharp edges.

After you have the old pane removed Clean up the frame and wood. Scrape off any paint that has been used and sand the rabbet grooves in which the glazing points were placed. Sand them to bare wood surfaces, so that you can paint the frames with the same color. After sanding the wood you can apply a layer flax oil. This will help extend its life.

Next, measure the dimensions of the window replacement companies's opening. It is necessary to take horizontal and vertical measurements of the entire opening, as well as the thickness of the old pane.

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.
