Glass
Replace your single-paned windows with tempered or insulate glass to improve energy efficiency, reduce noise, and protect the historic integrity of your older home. Most homeowners with basic hand tools can repair the window pane. You will also require an extra window pane, glazier's tips, pliers, and latex glaze putty. If needed, you can make use of a heat gun to warm the old putty. Wear safety goggles and gloves prior to beginning. Working with broken glass could result in serious injuries.
Remove any broken glass pieces that remain. It is recommended to use pliers for this however, a flathead may work equally. Use a wood chisel, or putty knife to get rid of any remaining old putty around the frame and the window sash. Be careful to not scratch the window sash. Be careful and slow. This is best done on a ladder, not the ground. Also, you should have someone lower to hold it steady.
Make sure the window frame is ready to receive the new pane when you have removed the old putty. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of the width and height. These measurements can be sent to an hardware or home centers store to get a piece cut of stock glass to the right size. You can also cut the glass yourself, if you have the appropriate tools.
After installing the new pane, run a small bead of caulking along the edge to ensure it is weatherproof. Install a glazier’s point on both sides of the frame. This will help secure the pane. The points shouldn't be too tight that they cause friction between the frame and sash However, they should not be loose.
Before applying the putty on the surface, you must knead it thoroughly until it becomes soft and free of lumps. Then you can roll it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from corner to corner to ensure it's even and smooth.
Glazier's Points
The glazier's points are tiny triangular pieces of metal that help secure the glass to the frame without causing damage to the delicate surface. It's simple to learn how to use this hidden tool and you can save money on the expense of a professional installation.
After taking off the old putty, glazier points and any residue, clean the frame thoroughly using a utility knife. If necessary, lightly sand the wood in the grooves of the rabbet to smooth rough areas. If you decide to sand the wood, ensure you protect it with painter's tape to avoid accidental damage.
Write down the exact dimensions of the frame. Bring these measurements to a hardware store or home center, and have the new pane cut smaller than the frame's opening. This will ensure a tight fit, and allow for expansion and contraction.
Place the new pane in the frame and press it down using your hands. Use the point of the chisel or the back of the putty blade to tap the glaziers' points as illustrated in Figure 11. After you're done, the points should be flush with the top edge of the pane. the shoulders of the points should be just below the lip of the rabbet groove.
Apply a small amount of glazing compound over the edges of the new glass and in the rabbet grooves, to seal and protect them. Let it dry and cure completely.
After the glazing compound dries and the glazing compound is dry, you can install the new window sash. First, you need to coat the wood with a thick layer of linseed. This will keep the new putty from taking up moisture and deteriorating and cracking with time. Use a brush to apply this coat, or the tip of the blade. Then, use the chisel on the back of the putty tool or the back of the putty handle to gently hit the new sash, or glazier's point into rabbet grooves. Repeat this process in intervals of 10 inches all around the frame.
Putty
A hurled baseball or a rock that is errant or a fallen branch can cause a window to crack or break. Fortunately, windows can be repaired by simply putting a brand new piece of glass in its the right place. The glass is held in place by a small metal clip, referred to as the glazier's point, and putty. This compound is also referred to as glazing compound. Before installing a new pane, first take out the old one and clean up the area with the help of a rag, an abrasive scraper that is a pull type or the wood chisel. Wear safety glasses and gloves while working. If the window is glued to the frame, you'll need make use of a heat gun to soften the adhesive before prying it free.
If you are planning to replace the original sash in the future, take care to remove any molding pieces 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 on the glass. This will ensure that it doesn't leak over time or discolor.
Take the glazing points out of the rabbets, the grooves in the sash where the glass sits. If they are hard to cut, place a hand tool such as a heating gun over them for a few minutes to soften them. If you're using a heat gun, be cautious not to cause damage to the sash or its railings by holding the tool too closely.
Make a bed for your new pane after removing the old glaze points and putty. Roll a rope made of glazing compound between your fingers, and make it around 1/2 inch thick. Press it into the rabbets, where the glass will be put. It's important that the glass is positioned against the putty on both sides If you have to, lightly tap the glass into the rabbet with your thumb.
If the new pane has damaged, you can use a silicone caulk or glass glue made from solvents to cover the crack before pressing it into the sash. Otherwise, you'll need to apply putty over the crack to form an impervious seal to keep water out. Once the putty is dry remove the oily film off of the glass and allow it to dry completely before you paint. If you paint before the putty is completely dry, it won't create an effective seal and could leak or discolor over time.
Paint

If you are working with a large glass window, first make sure it is securely fixed to the frame. This job can be done relatively easy and fast using the right tools and techniques.
When you are ready to begin with the removal of the window pane. Remove the metal glazing points that are attached to it. These are essentially small metal triangles that function as "nails" which hold the window in within the frame of wood. They are buried beneath a layer of glazing putty, which is then cured to form a solid, molded wedge which holds the window in place and hides the window's points.
Once you have the old pane taken away clean the surrounding frame and
Replace Window Pane wood. Scrape off any old paint, and sand the rabbet grooves that the glazing points were. These should be sanded down to bare wood so that you can paint them the same color as the rest the frame. After sanding the wood then apply a layer of flax oil. This will help to prolong the life of the frame.
The next step is to determine the width of the
window replacement near me opening. You will need to take horizontal and vertical measurements of the entire opening as well as the thickness of the old pane.
