How to Do Window Pane Replacement

If a window pane breaks or breaks It should be replaced immediately. It could lead to a decline in energy efficiency, or allow moisture to accumulate between the two panes.

The replacement windows cost of a window pane is less costly than replacing the entire window and can be easily accomplished by the average homeowner. To replace a pane, you will need to remove the old window, 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 existing pane. This can be a dangerous job, so it is important to wear safety equipment such as gloves and a face mask. If possible, it is best to work on the ground and use a ladder that can be secured securely to prevent falling. Once the old pane has been removed, you can begin working on the window frame. It is now an ideal time to lightly sand the frame. After this apply a layer of linseed oil on the wood frame to help the glazing compound remain flexible.

When you are ready to start the actual project ensure that your workspace is free of any debris and that you have all the tools you'll require. You will require a utility knife to scrape off any old putty that remains on the glass or within the frame of the window. It might take some time and effort however, it is essential to ensure that you get a top-quality product.

After you have removed the old putty you will have an opening that is clear for your new window pane. To make sure that the new window will fit, measure the opening and subtract 1/8" from the width and the length. It is also recommended to take a shard of the old pane to the local hardware store so that you can match the type and thickness of glass.

Window panes are not just meant to be pretty, they can actually make your house more efficient in energy use by reducing heat loss, glare, and noise. Replacing just one window pane can be a simple task.

Once you have replaced the broken pane, it must seal and caulk the edge of the new window in order to keep it in its place. This will not only give you a a great aesthetic finish, but it will also ensure that the new window is energy efficient and watertight. If you're trying to save money on your energy bills, you should also consider installing an exterior film that will decrease the amount of heat that is lost through windows.

Take the Putty off

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

To begin the process of removing the putty, first remove any nails or spriggs holding the window in place. These nails were used prior to when upvc and double glazing came onto the market to hold the glass in place. These nails are usually in the corners and can be removed using the help of a screwdriver or a hacksaw if they are visible. If they are hidden, you'll require a small chisel (or putty chisel) to remove the frame.

Mineral spirits are needed to get rid of any old putty left after removal of the nail. This product can be purchased at many hardware stores. It should be used in an area that is well ventilated. Use the oil in brief bursts because overheating the paint or wood can make it crack or explode.

Another option is to employ a heat gun to soften the putty. This method is more effective with putty which has been painted or hardened. Make sure to keep moving when using the heat gun since being stationary for too long could cause burning of the wood and cause cracked glass.

Steel wool can be used to get rid of the putty. However, this method is less efficient and may cause a mess. This should only be used as a last resort, and is not recommended for homes with children.

Remove the metal Glazing Points

A baseball thrown or the tree branch that is blown off can damage a windowpane. Although most people think that a broken windowpane requires full replacement of the frame and sash, in some cases just replacing the glass is enough to fix the view from your home and also save energy costs.

The first step in replacing a window is to remove the metal glazing points that hold the old pane in place. Using a putty knife, scrape away as much of the softened glaze as possible to expose the glass points. There should be four points, one on each side of frame. Once you have a clear view of the metal using needle-nose pliers, hold each one in your hands and pull straight out. Be careful not to prick too hard; if the point is stubborn or breaks, you may end up damaging the frame and will need to replace it.

Once the putty as well as the metal glazing points are removed, you can begin to prepare the frame for the new pane. Clean the grooves where glass is to go and make sure they are clean and free of dents and cracks. A heat gun is useful in this process however, be careful and use a low temperature to prevent the wood from bending or becoming damaged.

Next, if the glass is double pane glass take a shard of the window you used to replace to make sure that the new pane is properly fitted. Spread a thin layer of silicone sealant onto the inner frame rabbet, and then press the new glass onto it. Cut off any excess sealant with an edger, then paint the exterior to finish.

If you only have one glass pane do not bother with this step. If the thickness of the new glass differs from the one you had previously one, you'll require a new piece of glass in the correct size at 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 additional support and prevent it from falling off.

Installing the New Pane

Window panes aren't just there for aesthetics, they also improve energy efficiency, protect your home from the elements and insects, as well as improve security. When they are damaged or broken, it's important to replace them immediately. However, many homeowners don't know how to do it themselves. It's actually quite simple to change a window. All you need is some supplies and simple steps.

Start by removing your old windowpane. Be careful not to cut yourself. Be sure to have a towel on hand to wipe off any remaining glass. Keep the fragments in case you require a new window. After removing the old glass take a measurement of the opening of the frame using a tape. Write down the dimensions and subtract 1/8 inch from each side to arrive at the new glass size. This will result in an exact fit and allow for natural expansion and contraction. You can take the measurements to an area hardware store or home improvement shop and they will cut a new piece of glass for you. Bring a piece of glass from the old window that matches the thickness and the type.

Apply a small amount of latex caulk to 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 around the edge of the glass. There will be two points on each side for a total eight.

If you have any leftover wood molding that is around the edges of the frame, you can replace these as well. Make sure you clean the molding and putty thoroughly before reinstalling them to ensure they do not interfere with the new pane.

While it's tempting to put off replacing a broken window pane, doing so can cause further damage to the glass as well as the surrounding sash. It also increases the chances that you'll need to replace the entire window in the future. Anyone with a basic tool can replace a single broken pane of glass.
