This may take some time and effort, but it is essential to a quality finished product.

Once you've removed all the old putty you'll have a clear opening for the new pane.

Window panes can make your home more efficient by reducing heat losses, glare and noise. Luckily, replacing just one window pane is a easy task you can complete yourself.

These nails were used to keep the window in place before upvc window handle replacement or double glazing was made available. They are usually located in the corners of the frame and can be removed using the screwdriver if they're exposed or cut off with hacksaw. If any are hidden, you'll have to use a small chisel (or putty chisel) to remove them from the frame.

Mineral spirits are needed to remove any old putty that remains after removal of the nail. This product is available at most hardware stores and is best utilized in a well-ventilated area. Use the oil in brief intervals, as overheating paint or wood can make it to crack or explode.

Another alternative is to use a heat gun to soften the putty. This is more effective for putty that has been painted over or is hardened, and is extremely effective. Be sure to move when using a heat gun. If you keep it in the same spot for too long, the wood can be burnt and the glass can crack.

You can also employ steel wool to get rid of the putty, but this method isn't as effective and could be very messy. This method should be used only in a last-resort and is not recommended for homes with children.

A baseball thrown or a tree branch that flies off could damage a window. Although most people assume the broken window will require a full replacement window panels of both the frame and the sash, it is possible to fix the view and cut down on energy bills by replacing only the glass.

The first step in replacing windows is to take off the metal points which hold the previous pane in place. Using a putty knife, scrape as much of the softened glaze as you can to expose the points. There should be at most four points, all centered on each side of the frame. Once you are able to see the metal, use needle-nose pliers to hold each one in your hands and pull straight out. Be careful not to pull too hard. If the point is stifling or breaks, you may damage the frame and need to replace it.

Utilizing a heat gun can help with this process. Be careful and make use of low temperatures to prevent the wood from warping or becoming damaged.

Next, if the glass is double pane take a shard of the window that was previously used to ensure that the new pane fits properly. Apply a thin layer of silicone sealant over the inside frame rabbet, and then press the new glass onto it. Cut off any excess sealant with the blade of a razor, then paint the exterior to finish.

If you only have one pane of glass to be installed then skip this step and go directly to the next. If the new glass is different thickness than the original, purchase an appropriate-sized piece of glass from a local glass cutter. Before installing the new pane, place a glazier's push point in every corner of the frame rabbet (two on each side for a smaller window, more for larger windows). This will provide additional support to the pane, and also help keep it from getting smashed over time.

Take the measurements to your local hardware or home improvement store and have them cut a piece of glass for you. If you are able take a shard from the window that is already in use to match the thickness and type.
