How to Do Window Pane Replacement

It is crucial to replace a broken or cracked window pane as soon as is possible. This can lead to an energy loss or a build-up of moisture between the two panes.

A homeowner with a basic knowledge of how to replace a window's pane for only a fraction of the cost of replacing a complete window. To replace a pane, you will need to remove the old window and clean the frame and then apply a new layer of putty.

Removing the old Pane

The first step to replace windows is to remove the old pane from the window. It is important to use protective equipment, such as gloves and a face mask. It is also a good idea to work on the ground when possible and to utilize a ladder that could be secured securely to avoid falling. After the old pane has been removed, you can start working on the window's frame. This is the perfect time to scrub the area and lightly sand it. Apply a coat of linseed to the frame of the wood to help the glazing compound remain flexible.

If you are ready to begin the actual work ensure that your workspace is free of any clutter and that you have all the tools you will need. You will require an utility knife to scrape away any old putty that remains on the glass or within the frame of the window. It may require some effort and time however, it is essential to ensure the highest quality finished product.

After you remove the old putty, you'll have an open space that is ready to accommodate your new window. To ensure that the new window will fit to the opening, measure it and subtract 1/8" from the width and length. It's also an excellent idea to bring a shard of the old pane to the local hardware store to match the thickness and type of glass.

Window panes can help make your home more efficient by reducing heat losses and noise, as well as glare. Replacing just one pane of windows is not a difficult task.

After replacing the broken pane you will need caulk and seal the edges of the window to hold it in place. This will not only provide an attractive aesthetic, but it will also ensure that the new window is watertight and energy efficient. The installation of window films can save you money on energy bills by cutting down on the amount of heat lost through your windows.

Take the Putty off

It is often difficult to get rid of the glazing putty used to secure glass panes that are tempered in their frames. It becomes hard when it dries, and this can make it very difficult to remove without damaging the glass. To avoid this it is essential that the old putty be removed before installing the new window pane. The removal of window putty isn't an simple task however it is doable with a bit of perseverance and effort. Wearing leather gloves and eye protection is recommended when working around glass. It can be dangerous.

Remove any nails or spriggs that hold the window in position before you begin removing the putty. These nails were used before upvc and double glazing came on the market to help hold the glass in place. They are usually located in the corners of the frame and can be removed with a screwdriver if they are exposed, or by cutting them off using a hacksaw. If any are hidden, you'll have to use a small chisel (or putty chisel) to remove the frame.

Once the nail is removed you'll need to use mineral spirits to clean out any remaining pieces of old putty. This product is available from many hardware stores and is best used in a ventilated area. You should also use the oil in short intervals to avoid over heating the wood and paint since this can cause it to crack or explode.

Another alternative is to use the heat gun to soften the putty. This works best with putty that has been painted over or is hardened and can be very efficient. Keep moving when using a heat gun. If you put it in the same 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 isn't as effective and can get messy. This method should be used only in a last-resort and is not recommended in homes with children.

Removing the Metal Glazing Points

A baseball hit or the tree branch that is blown off could damage a window. And although most people assume that a broken windowpane requires total replacement windows and doors of the frame and sash, sometimes just replacing the glass can be enough to restore a home's view and save energy costs.

The first step in replacing glass in windows is to remove the metal points that hold the previous pane in place. Scrape away as much of the softened glass as you can using the help of a knife to expose the points. There should be four points each on the opposite side of frame. Once you can see the metal, use needle-nose pliers to grasp each one and pull it straight out. Don't try to pry too difficult. If the point is inflexible or breaks, it may damage the frame.

Once the putty and glazing points made of metal have been removed, you can start to prepare the frame for the new pane. Clean the grooves where the new glass will go and ensure they are smooth and free of cracks and dents. A heat gun can be helpful for this, but remember to be cautious and utilize a low temperature to stop the wood from warping or causing damage.

If the glass is double-paned you can take a piece of the old pane to ensure that the new one is positioned correctly. Spread a thin layer of silicone sealant over the inside frame rabbet and press the new glass into it. Trim any excess sealant using the blade of a razor, then paint the outside to complete.

If you only have one pane of glass that you want to install then skip this step and go directly to the next. If the new glass is different thickness from the original, purchase an appropriate sized piece of glass from a local glass cutter. Put a glazier's pushpoint at every corner of the frame's rabbet, prior to installing the new pane (two per side for windows with small windows, more for large windows). This will give the pane more support and prevent it from falling off.

Installing the New Pane

Window panes don't only provide aesthetics, they also improve efficiency of energy, shield the house from rain and insects, and improve security. When they are damaged or broken, it's crucial to replace them right away. Many homeowners are unaware of how to replace a window. Fortunately, it's quite easy to replace a window pane. You just need a few supplies and some simple steps.

Start by removing the old windowpane making sure not to cut yourself while you work. Make sure you have a towel handy to clean up any remaining glass, and save the shards to make a new pane. After you have removed the old glazing take a measurement of the opening of the frame using a tape. Write these down and subtract 1/8 inch from each side to get the new size of replacement glass windows. This will ensure an exact fit and allow for natural expansion and contraction. Take the measurements to your local hardware or home improvement store and have them cut a piece glass for you. If you can, bring a shard from the existing window to match the thickness and type.

Once the new pane has been put installed, apply a small bead of caulk that is made of latex around the edges to create a seal between the glass and frame. Glazier's points need to be inserted into the holes of the frame along the glass's edge. You'll need two points on each side for eight points total.

You can also add any remaining wood molding around the frame's edges. Make sure to wash the molding and putty thoroughly before reinstalling it, so it doesn't interfere with the new pane.

Although it's tempting to procrastinate on replacing a broken window pane however, this can result in further damage to the glass and the surrounding sash. It also increases the likelihood that you'll need to replace the entire window in the future. Replacing a single damaged window pane is a relatively simple process that is achievable by any homeowner who has basic tools.
