Utilize a utility blade to scrape away any old putty that has accumulated on the glass or inside the window frame. This may take some time and effort, but it's essential to a quality finished product.

Once you've removed all the old putty, you'll have a clear opening for the new pane. Take a measurement of the opening and subtract 1/8 inch from both length and width to ensure that you get an entirely new window pane that fits perfectly. It is also recommended to take a small piece of the old pane to the local hardware store to match the thickness and type of glass.

Window panes aren't only meant to be pretty, they can actually make your home more efficient in energy use by reducing the loss of heat, glare and noise. The good news is that replacing a single window pane is a simple task that you can tackle yourself.

After replacing the damaged window, you'll need caulk to seal the edge of the window to ensure it stays in place.

It is recommended to wear leather gloves and eye protection when working around the glass as it can be very dangerous.

Remove any nails or spriggs that hold the window in place before you begin to remove the putty. These nails were used prior to when double glazing and upvc came onto the market to keep the glass in place. These nails are usually in the corners and can be removed with a screwdriver or by using a hacksaw if they are visible. If any are hidden, you will require a small chisel (or putty chisel) to remove the frame.

Mineral spirits will be needed to remove any old glue that remains after removal of the nail. This product is available from many hardware stores and should be used in a ventilated area. Apply the oil in short bursts because overheating the paint or wood can make it to crack or explode.

A heat gun can also be utilized to soften the putty. This will work better on putty that has been painted over or hardened and can be extremely efficient. Be sure to move around when using the heat gun because being stationary for too long can cause burns to the wood and lead to cracked glass.

Steel wool can also be used to take away the putty. However this method is not as effective and can get messy. This should only be used as a last resort, and is not recommended for homes with children.

Removal of the Metal Glazing Points

There should be four points, one on each side of frame. Once you see the metal, grab each with pliers that have needles and pull straight out. You should not pry too hard. If the point is stubborn, or breaks, it could damage the frame.

Once the putty as well as the glazing points made of metal have been removed, it is now time to prepare the frame for the new pane. Make sure the grooves are free from cracks and dents. A heat gun is useful in this process, but remember to be cautious and use a low temperature to prevent the wood from warping or causing damage.

If the glass is double-paned, you can take a piece of the previous pane to ensure that the new one fits correctly. Spread a thin layer silicone sealant over the inside frame rabbet and press the new glass into it. Cut off any excess sealant with an edger, then paint the outside to complete.

If you have only one glass pane you can skip this step. If the new glass is different thickness than the original, purchase the appropriate size piece of glass from your local glass cutter. Before installing the new pane place a glazier's pushpoint in every corner of the frame rabbet (two on each side for a smaller window, more for larger windows). This will give the pane additional support and prevent it from falling off.
