How to Replace Window Panes

A cracked window pane is a nuisance. It could also be a chance to upgrade your glass to energy-efficient or insulated windows and benefit from improved comfort, increased potential for resales, and less costs.

It's a task you can tackle yourself at a fraction of the cost of hiring an expert. It requires the right equipment and an hour or two of your time.

Glass

If your single-pane windows are old, deteriorating or broken replacing them with modern glass that is tempered or insulated can improve energy efficiency and reduce noise while maintaining the historical integrity of older homes. Most homeowners with basic hand tools can repair the window pane. Alongside a replacement glass for windows pane, the following components are needed such as latex glazing putty; glazier's points; pliers; and a heat gun for warming the old putty, if necessary. Before starting, wear gloves and safety glasses as working with broken glass can cause injuries.

Take away any broken glass pieces remaining. This is best accomplished with a pair of pliers, however, a flathead screwdriver may be effective in a pinch. Use a wood chisel, or putty knives, to take away any remaining old putty around the frame and the window sash. Be careful to not break the window sash. Be careful and slow. It is a good idea to do this on a stable ladder rather than on the ground, and to place someone on the sash to help hold it steady.

Once you have removed all the old putty, you can prepare the window frame to accommodate the new pane. Find the width and the height of the opening for the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be sent to a home center or hardware store to have an item cut from glass stock to the proper size. You can cut the glass yourself if you have the appropriate tools.

After putting in the new pane After installing the new pane, apply a small amount of caulking along the edge to make it weatherproof. Then install a glazier's point on the frame's opposite side to hold the pane in place. The points shouldn't be so tight that they create friction between the sash and frame, but they also should not be too loose.

Before applying the putty to the surface, you must knead it thoroughly until it is soft and free from lumps. Cut it into pencil-sized pieces. The first strip should be placed in the corner of the frame, moving from one corner to another to ensure it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of steel that help secure glass into the frame of a window without scratching or damaging the fragile surface. Knowing how to use these little helpers is easy and can save you money on a professional installation or the cost of purchasing new glass.

After the old putty as well as glazier's points are removed Clean the frame thoroughly using a utility knife to remove any remaining residue. Lightly sand the frame in the rabbet grooves, if necessary, to smooth out rough areas. If you do sand the wood, be sure to protect it with painter's tape to avoid accidental damage.

Take the dimensions of the frame and [empty] write down accurate measurements. Take these measurements to a hardware store or home center, and have the new pane cut slightly smaller than the frame's opening. This will ensure a secure fit and leave room for expansion and contraction.

Insert the new pane into the frame and push firmly using your hands. Then use the point of your chisel or back of the putty knife to pierce the glazier's points as illustrated in Figure 11. The glazier's point should be in line with the top edge of the pane and the shoulders should be just beneath that lip.

Apply a thin bead of glazing compound over the edges of the glass that has been made and into the rabbet grooves, to seal and protect them. Let it dry and cure completely.

Install the new window sash when the glazing compound has dried. First, coat the wood with a heavy coat of Linseed oil. This will stop the new putty from sucking in the moisture and deteriorating and cracking with time. Apply the coat using a brush or the edge of your putty knife, and then use the chisel or the back end of the putty knife to gently hammer in the new sash and glazier's points into the rabbet grooves. Repeat this procedure every 10 inches along the frame's perimeter.

Putty

A baseball thrown at you, an errant rock or a fallen branch can cause a window pane to crack or break. Fortunately, the majority of windows can be replaced by simply placing a new piece of glass in its the right place. The glass is held in place by small clips made of metal called a glazier's point and putty, also called glazing compound. Remove the old pane and clean the area with an abrasive, pull-type scraper or wood chisel. Wear safety glasses and gloves while working. You'll need a heat gun if the window is glued into the frame.

If you're planning to install the original sash in the future, take care to remove any pieces of molding that secure the old pane. Sand the sash until it's flat and ready for new caulk. Once the sash is reinstalled then, you can apply a silicone caulk over the glass. This will ensure that it doesn't be leaking or fade over time.

Take out the glazing points in the rabbets. These are the grooves in the sash, which is where the glass is. If they are hard to cut, place an instrument such as a heating gun over them for a few minutes to soften them. If you're using a heat gun, be careful not to cause damage to the railings of the sash or the sash itself by placing the tool too tightly.

Prepare the bed for your new pane after removing the old glaze points and putty. Roll a rope of glazing compound between your hands, and form it to be around 1/2-inch thick. Place it into the rabbets where the glass will be placed. It's important that the glass is positioned against the putty on both sides, so if you need to do so, gently tap the glass into the rabbet with your thumb.

If the new pane is cracked, you can use the silicone caulk or glass glue made from solvents to seal the crack prior to pressing it in the sash. If the crack isn't sealed, you'll need to use putty to keep water out. When the putty dries, clean the oily film off the glass using a rag and allow it to dry completely before painting. Paint before the putty is completely dry. It will not create a solid seal and could discolor or leak over time.

Paint

If you've suffered a break in a window pane, you might be concerned about the expense of a new one. But the truth is that replacing one glass pane does not have to break the bank if you do it yourself. Even a double-paned window could be replaced for a fraction of what it will cost an expert.

First, if you're working on a large-sized window, make sure it is securely fixed to the frame. With the right tools and techniques to make this task relatively easy and fast.

When you are ready to begin, remove the old window pane. Remove the metal glazing points that are attached to it. These are tiny triangles of metal that act as "nails" that hold the window in the frame. They are placed under a glaze putty or bead that hardens to an unbreakable wedge that holds the frame in place and conceals the edges.

Once you have the old pane removed, clean up the surrounding frame and wood. Scrape away any old paint and sand [empty] down the rabbet grooves where the glazing points were. Sand them down to clean wood surfaces, so that you can paint the frames the same color. After sanding the wood you can apply a layer flax oil. This will help to prolong the life of the frame.

The next step is to determine the size of the window's opening. You'll need to determine the vertical and horizontal dimensions of the entire opening, as well as the thickness. Subtract 1/8 inch from each measurement to ensure that you get a precise size for the new pane. This will also allow for expansion and contraction of the glass during seasonal change. Take these measurements to the hardware or home improvement store, and they will have the glass cut for you.

Now, it's time to bed the new window pane. To do this, place the pane inside the frame and move it around until a 1/16 inch of putty remains between the edge of the glass and the sash on all four sides. Use a putty knife to smear the putty evenly, making sure that there isn't an excessive amount of excess putty in the corners and along the edges. When the putty dries, it can be painted with the same color as the frame to prevent water and air from leaking into the frame and causing fogging.
