How to Do Window Pane Replacement

It is important to replace a broken or cracked window pane as soon as you can. This can cause a loss in energy efficiency, or allow moisture to build up between the two panes.

The replacement of a window pane is cheaper than replacing an entire window and can be easily accomplished by homeowners of all ages. To replace a window, you'll need to take out the window that is in use and clean the frame before you apply new putty.

Remove the Old Pane

The first step in replacing a window pane is to remove the old pane from the window. This can be a dangerous job, so it is essential to wear protective equipment like gloves and a mask. It is also a good idea to work on the ground if feasible and to utilize a ladder that can be secured safely to avoid falls. After the old window is removed, you can start working on the window's frame. It is now a good idea to lightly sand the area. Apply a coat of linseed on the frame of the wood to allow the glazing compound to remain flexible.

When you're ready to start the work, ensure that your workspace is free of all debris and that you have the tools you need. Use a utility blade to remove any old putty that has accumulated on the glass and in the window frame. It might take some time and effort however, it is essential to ensure the highest quality finished product.

Once you have removed all the old putty you will have a clean opening for your new window. Find the dimensions of this opening and subtract 1/8 inch from both the width and length to ensure you get an entirely new window pane that will fit properly. You can also take a portion of the old window to a hardware store to match the type of glass and thickness.

Window panes are not just meant to be pretty, they can actually help make your home more efficient in energy use by cutting down on heat loss, glare, and noise. Replacing just one pane of windows can be a simple task.

Once you have replaced the broken pane, it will need to seal and caulk around the edge of the new window to keep it in position. This will not give your window a beautiful look, but it will also make it energy efficient and waterproof. If you're looking to save even more money on your energy bills, you should also think about installing an exterior film that will decrease the amount of heat lost through windows.

Removal of the Putty

The glazing putty that is used to hold panes of glass in frames can be extremely difficult to remove. It becomes hard as it dries and can make it very difficult to remove without breaking the glass. To avoid this, the old putty should be removed before installing the new window. The removal of window putty isn't an simple task but it is doable with a little perseverance and effort. It is recommended that you wear leather gloves and eye protection while working around the glass as it can be very hazardous.

To begin removing the putty, you must first remove any nails or spriggs that are holding the window in place. These nails were used to keep the window in place prior to when double or upvc glazing was available. Usually these nails are in the corners of the frame and can be removed using an screwdriver when they are exposed, or by cutting them off with a hacksaw. If any are hidden, you'll have to use a small chisel or putty chisel to break them free from the frame.

After the nail has been removed, you'll need to use mineral spirits to remove any remnants of old putty. The product is available at most 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.

Another option is to use a heat gun to soften the putty. This method is more effective on putty which has been sprayed or hardened. Keep moving when using a heating gun. If you leave it in the same spot for too long, the wood may be burned and the glass cracked.

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

Remove the Glazing Points of Metal

A baseball hit or a tree branch that flies off could damage a window. While most people believe that windows that are damaged requires a complete replacement of both the frame and the sash, it is possible to restore the view and reduce costs for energy by only replacing the glass.

The first step in a window glass replacement is to remove the metal glazing points which hold the old pane in place. Scrape off as much of the softer glazing as possible with a putty blade to reveal the points. There should be four points that are on either side of the frame. Once you are able to see the metal, use needle-nose pliers to grip each one and pull it out straight. Be careful not to prick too hard. If the point is stifling or breaks, you could cause damage to the frame and have to replace it.

After you have removed the metal points and putty, you can begin to make the frame. Make sure the grooves are free from cracks and dents. Utilizing a heat gun can assist in this process. Be careful and make use of low temperatures to prevent the wood from warping or becoming damaged.

If the glass is double pane, bring a shard of the window that was previously used to ensure that the new one is properly fitted. Spread a thin layer silicone sealant over the inside surface of the frame rabbet and press the new glass into it. Then, trim any excess sealant using a razor blade and apply a coat exterior paint to finish the job.

If you only have one pane of glass to install, skip this step and move directly to the next. If the new glass replacement in windows is a different thickness than the original, purchase an appropriate sized piece of glass from your 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 small window, and more for larger windows). This will give the pane extra support and stop it from being dislodged.

Installing the New Pane

Window panes do more than just look attractive They also improve energy efficiency, shield your home from pests and rain, and increase security. If they're damaged or broken, it is essential to replace them as soon as possible. A lot of homeowners aren't aware of how to replace a window. Fortunately, it's quite easy to repair a window. All you need is some supplies and easy steps.

Start by removing your old windowpane. Be careful not to cut yourself. Make sure you keep a towel nearby to clean off any remaining glass. Keep the fragments in case you require a replacement window. After you have removed the old glazing, measure the rough opening of the frame using tape. Note these down, and subtract 1/8 inch from each side to create the new glass size. This will ensure a tight fitting glass and allow for the natural expansion and contraction. You can bring the measurements to a local hardware store or a home improvement store and they will cut a new piece of glass for you. Bring a piece of glass from the old window that is the same thickness and the type.

Once the new pane is installed and the frame is set, apply a small amount of caulk that is made of latex around the edges to create a seal between the frame and glass. Then, put glazier's points into the holes in the wood frame to the edges of the glass. You will need two points on each side, making a total of eight.

You can also put in any wood molding that is left around the frame's edges. Make sure to wash the molding and putty well before reinstalling it, so it will not interfere with the new pane.

While it's tempting to procrastinate on replacing a damaged or broken window, doing so can cause further damage to the glass as well as the surrounding sash. It also increases the likelihood that you'll have to replace the entire window in the future. Anyone with basic tools can replace a single broken glass pane.
