How to Do Window Pane Replacement

It is crucial to replace a broken or cracked window as quickly as possible. This could lead to the loss of energy efficiency or the accumulation of moisture between the two panes.

A homeowner with a basic knowledge of how to replace a window pane for less than the cost of replacing an entire window. To replace a window pane, you'll need to take out the old window, clean the frame, and then apply a new layer of putty.

Remove the old Pane

The first step in replacing windows is to take off the window. It is important to use protective equipment, such as gloves and masks for face. If you are able, it is best to work on the floor and use a ladder that can be secured securely to avoid falling. Once the old pane has been removed, you can begin working on the window frame. It is an ideal time to lightly sand down the area. After that, apply a coat of linseed oil onto the frame of the wood to aid in helping the glazing compound remain flexible.

When you are ready to begin the actual work, make sure that your work space is clear of any debris and that you have all the tools you'll require. You'll need an utility knife to scrape away any old putty that remains on the glass or within the frame of the window. It might take some effort and time however, it is essential to ensure that you get a top-quality product.

Once you have removed all the old putty you'll have a clean opening for the new pane. To ensure that the new window will fit take a measurement of the opening and subtract 1/8" from the width and the length. You could also bring a piece of the old window to the hardware store to match the type of glass and the thickness.

Window panes aren't only meant to be pretty, they can actually make your house more energy efficient by decreasing heat loss, glare and noise. Replacing a single window pane is a simple job.

Once you have replaced the broken pane, you must seal and caulk around the edge of the new window in order to keep it in position. This will not just give your window a stunning appearance, but also make it more energy efficient and waterproof. If you are trying to save money on your electric bills, you could also think about installing windows with a film that will decrease the amount of heat that is lost through windows.

Removing the Putty

It can be difficult to remove the glazing putty that is used to hold glass panes that are tempered in their frames. It can be difficult to remove as it hardens and dries. To avoid this, it's best to remove the old putty prior to installing the new glass. It's not easy to get rid of window putty however, with perseverance and determination it can be done. Wearing leather gloves and eye protection is a must when working with glass. It can be dangerous.

Remove any nails or spriggs securing the window in place before you begin removing the putty. These nails were used before double glazing and upvc replacement window handles were introduced on the market to help hold the glass in place. They are usually located in the corners of the frame and can be removed using an screwdriver when they are exposed or cut off with hacksaw. If any are hidden, you'll need to use a small chisel or putty chisel to cut them free from the frame.

Mineral spirits are needed to remove any old glue that remains after removing the nail. This product is available from the majority of hardware stores and should be utilized in a well-ventilated area. It is recommended to apply the oil in short intervals to avoid over heating the wood and paint as this can cause it to crack or explode.

Another option is to use the heat gun to soften the putty. This is more effective for putty that has been painted over or is hardened, and is extremely efficient. Keep moving when using a heat gun. If you put it in the same spot for too long, the wood may be burned and the glass may crack.

You can also use steel wool to remove the putty, however this method is not as effective and can be very messy. This should be used only as a last resort and is not recommended for homes with children.

The removal of the metal Glazing Points

A hurled baseball or an errant tree branch can cause a lot of damage on a windowpane. While most people believe that a broken windowpane requires full replacement of the frame and sash simply replacing the glass is enough to fix the view from your home and also save energy bills.

The first step to replacing glass in windows is to remove the steel points which hold the previous pane in place. Scrape away as much of the softened glass as you can with a putty blade to reveal the points. There should be at most four of them, evenly spaced on either side of the frame. When you can see the metal, grab each using needle-nosed pliers and pull them straight out. Be careful not to pull too hard. If the point is stubborn or breaks, you could end up damaging the frame and will need to replace it.

After the putty and the glazing points made of metal have been removed, you can start to prepare the frame to accommodate the new glass. Make sure the grooves are clean and free from cracks and dents. Use a heat gun to help with this process. But be cautious and utilize low temperatures to avoid the wood warping or becoming damaged.

If the glass is double pane glass, bring a shard of the window that was previously used to make sure that the new pane is a good fit. Apply a thin layer of silicone sealant onto the inner surface of the frame rabbet, then press the new glass into it. Cut off any excess sealant with an edger, then paint the exterior to complete.

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

Installing the New Pane

Window panes aren't just there for looks; they help increase efficiency of energy, shield the house from rain and insects, and increase security. Therefore, if they break or become damaged, it's important to replace them as soon as possible. Many homeowners are not aware of the best way to replace a window pane. Fortunately, it's quite simple to change a window. All you need is a few supplies and some simple steps.

Begin by removing the old window making sure not to cut yourself as you work. Make sure you have a towel available to clean any remaining glass, and keep the shards for a replacement pane. Once the old glass is removed using a tape measure, you can use it to determine the measurements of the frame's opening. Write these down and subtract 1/8 inch from each side to get the new glass size. This will guarantee an extremely tight fitting glass and allow for natural expansion and contraction. Bring the measurements to your local hardware or home improvement store, and have them cut a piece glass for you. If possible, bring a shard from the window that is already in use to match the thickness and type.

Apply a small amount of latex caulk around the edges of the glass once it is in place. This will create a seal. Then, place glazier's pointing into the holes of the frame, centered close to the edge of the glass. You'll need two points per side to make an total of eight.

If you have any remaining wood moldings around the edges of the frame, you can replace these as well. Be sure to clean the molding and putty well before reinstalling it to ensure it doesn't interfere with the new pane.

It's tempting to delay replacing a damaged pane of glass, but this can cause further damage to the glass and surrounding sash. You may also need to replace the whole window in the future. Replacing a single broken window pane is a fairly simple task that can be accomplished by anyone with basic tools.
