Removal of the old Pane
The first step to replace a window pane is to remove the old pane from the window. It is important to use protective equipment, such as gloves and a face mask. If you can, it is best to work on the floor and use a ladder that can be secured safely to prevent falling. After the old window is removed, you can begin working on the window frame. This is the ideal time to scrub the area and lightly sand it. Apply a layer of linseed onto the frame of the wood after this to help the glazing compound remain pliable.
When you're ready to begin the work, ensure that your work area is free of all debris and that you have the tools you need. You will require a utility knife to scrape away any old putty that remains on the glass or in the frame of the window. It can take some time and effort, but it's essential to a quality finished product.
After you have removed all the old putty, you will have a clean opening to install your new pane. Measure the size of this opening and subtract 1/8 inch from both the width and length to ensure that you get a new window pane that fits properly. You can also take a portion of the old window to a hardware store to match the type of glass and thickness.
Window panes aren't only meant to be pretty, they can actually make your home more energy efficient by cutting down on heat loss, glare and noise. The good news is that replacing just one window pane is a easy task you can complete yourself.

The glazing putty that is used to hold panes of glass in frames can be difficult to remove. It gets harder as it dries and this can make it very difficult to remove without damaging the glass. To avoid this, it's recommended to take off the old putty prior to installing the new pane. Removing window putty is not an easy task however it is achievable with a bit of patience and effort. Wearing gloves made of leather and eye protection is a must when working with glass. It could be hazardous.
To begin removing the putty, first take out any nails or spriggs holding the window in place. These nails were used to keep the window in place prior to when double or upvc glazing was made available. Usually these nails are in the corners of the frame and can be removed with a screwdriver if they are exposed or by cutting them off using hacksaw. If any are hidden you will need to use a small chisel or putty chisel to break them free from the frame.
Once the nail is removed you'll need to use mineral spirits to remove any remaining bits of old putty. The product is available at many hardware stores and should be used in a ventilated area. It is recommended to use the oil in small bursts to prevent over heating the wood and paint as this can cause it to crack or explode.
Another alternative is to use a heat gun to soften the putty. This works best with putty that has been painted over or is hardened and can be extremely effective. Keep moving when using a heating gun. If you keep it in one place for too long, the wood may be burnt and the glass can crack.
Steel wool can also be used to take away the putty. However this method is not as efficient and can leave a mess. This method should only be used as a last resort and is not recommended in homes with children.
The removal of the metal Glazing Points
A hurled baseball, or an unruly tree branch can cause a lot of damage on a windowpane. While most people believe that a broken windowpane requires full

The first step in replacing a window is to remove the metal glazing points that hold the old pane in place. Utilizing a putty knife scrape away as much of the softened glaze as possible to expose the glass points. There should be at minimum four of them, centered on either side of the frame. Once you can see the metal then use needle-nose pliers to grasp each one and pull straight out. You should not pry too in a way that is too hard. If the point is stifling or breaks, it may cause damage to the frame.
Once the putty as well as the metal glazing points have been removed, you can begin to prepare the frame to accommodate the new pane. Make sure that the grooves are free from cracks and dents. A heat gun can be helpful in this process but be careful and utilize a low temperature to stop the wood from bending or becoming damaged.
If the glass is double-paned, you can bring a piece of the previous pane to ensure that the new one will fit properly. Then, apply a thin layer of silicone sealant on the inside surface of the frame rabbet, and apply the new window to it. Then, trim any excess sealant using a razor blade and apply a coat of exterior paint to complete the job.
If you have a single pane of glass to install, skip this step and go directly to the next. If the thickness of the new glass is different from the original, you will need to purchase a piece of glass in the proper size from your local glass cutter. Before installing the new pane put a glazier's push point in each corner of the frame rabbet (two on each side for a smaller window, and more for larger windows). This will give the pane more support and stop it from falling off.
Installing the New Pane
Window panes aren't just there for aesthetics, they also improve efficiency of energy, shield the home from rain and insects, and increase security.

Once the old glazing is removed, use a tape measure to find the dimensions of the frame's opening. Note these down and subtract 1/8 inch from each side for the new size of glass. This will ensure an exact fit and allow for the natural expansion and contraction. You can bring the measurements to an area hardware store or a home improvement store and they will cut a new piece glass for you. Bring a shard of glass from the old window that is the same thickness and shape.
Apply a small amount of caulk made from latex to the edges of the glass once it has been placed. This will form an airtight seal. Glazier's points should be placed into the holes of the wood frame along the glass edge. There should be two points on each side for an total of eight.
If you have any leftover wood molding around the edges of the frame, you can install them now, too. Be sure to clean the molding and putty thoroughly before reinstalling it, so it will not interfere with the new pane.
