Glass

Replace your old single-paned windows with tempered insulate glass to improve energy efficiency, cut down on noise, and preserve the historic integrity of your old home. Most homeowners with basic hand tools can repair windows with ease. You'll also require a replacement window seals window pane, glazier's suggestions, pliers, and latex glazing putty. If needed you may make use of a heat gun to warm the old putty. Before beginning, wear gloves and safety goggles as working with broken glass may cause injuries.

Begin by removing any remaining broken pieces of glass. It is best to use pliers for this however a flathead could be used 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 damage the window sash. Be careful and slow. This should be done on a ladder, not on the ground. Also, have someone below the sash ensure it is held steady.

Prepare the window frame to accommodate the new pane once 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 taken to an hardware or home centers store to get an item cut from glass that is in stock to the correct size. You can cut the glass yourself if you possess the appropriate tools.

After putting in the new glass Apply caulking around the edge. This will make the glass weatherproof. Then, you can install a glazier's pointing on each side of the frame to hold the pane in place. The points should not be so tight that they cause friction between the frame and sash however they shouldn't be too loose.

Before applying the putty to the surface, gently knead it until it is soft and free from lumps. Make it into pencil-sized strips. Apply the first strip to the corner of the frame. Work from corner to corner, making sure it is even and smooth.

Glazier's Points

The glazier's points are small triangular metal pieces 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'll save money on the expense of an expert installation.

After taking off the old putty, glazier points as well as any remaining residue clean the frame thoroughly using an utility knife. Lightly sand the wood into the rabbet grooves, if necessary, to smooth out rough areas. If you do sand the wood, make sure to protect it with painter's tack to avoid accidental damage.

Write down the exact dimensions of the frame. Bring these measurements to a hardware store or a home center and have the new pane cut slightly smaller than the frame's opening. This will ensure a secure fit, and allow for expansion and contraction.

Insert the new pane into the frame and press it down with your hands. Use the chisel's point or the back of the putty knife to tap in the glazier's points as shown in Figure 11. The glazier's point should be in line with the top edge of your pane, and the shoulders should be just below that lip.

Apply a thin layer of glazing compound on the edges of the new glass and in the rabbet grooves to seal and protect them. Allow this to dry and cure completely.

Install the new window sash after the glazing compound has dried. First, coat the wood with a thick coat of Linseed oil. This will prevent the newly-created putty from drying out or cracking when it absorbs moisture. Apply the coat using a brush or the tip of your knife, then use the chisel, or the back end from the putty knife to gently hammer the new sash and glazier's tips into the rabbet grooves. Repeat this procedure every 10 inches along the frame's perimeter.

Putty

A hurled baseball, an errant rock or a falling branch can cause a window pane to crack or break. Luckily, most windows can be replaced by simply putting a new piece in the proper place. The glass is held in place with tiny metal clips known as a glazier's point and putty, often called glazing compound. Remove the old pane and clean the area using a rag, a scraper that is a pull type or a wood chisel. Wear protective glasses and gloves when working. If the window is attached to the frame, you'll have to make use of a heat gun to soften the adhesive prior to taking it off.

If you are planning to replace the original sash in the future, take care to remove any pieces of molding that secure the old pane. Then you can sand the sash down to make sure it's flat and ready for new caulk. After the sash has been put back in place then, you can apply a silicone caulk over the glass. This will ensure that it doesn't get soiled or discolor over time.

Remove the glazing points from the rabbets and the grooves in the sash where the glass sits. If they're difficult to work out, try placing the hand tool, such as a heat gun to soften them up first. If you're using a heat gun, be cautious not to cause damage to the railings of the sash or the sash itself by using the tool too closely.

Create a bed for your new pane by removing the old putty and glazing points. Roll a rope of glazing compound between your fingers, replace Window Pane and make it about 1/2 inch thick. Then, press it into the rabbets in which the glass will sit. It is crucial that the glass sits on the putty on both sides If you have to do so, gently tap the glass into the rabbet using your thumb.

If the new pane has a crack you can fill it with a solvent-based glass glue or silicone caulk prior pressing it into the sash. Otherwise, you'll need to apply putty on the crack to form a tight seal and keep water out. After the putty has dried and the film is oily, wipe it off the glass with a rag and allow it to completely dry before painting. If you paint before the putty has completely dry, it won't form an effective seal and could be leaking or discoloring in time.

Paint

If you've experienced a broken window pane, you might be worried about the cost of replacing it. However, replacing a single glass pane doesn't require a huge amount of money when you do it yourself. Even a double-paned window can be replaced for a fraction of what it will cost a professional.

If you are working on a large-sized window, make sure that it is securely fastened to the frame. This task is relatively easy and fast with the proper tools and techniques.

Once you're ready to begin with the removal of the old window pane by removing the glazing points made of metal that are connected to it. They are basically tiny metal triangles that act as "nails" that hold the window in place in the wood frame. They are placed beneath a layer of glazing putty that hardens into a solid, formed wedge that holds the window firmly in place and hides the points.

After removal of the old pane clean the frame and the wood. Scrape off any paint and sand down the rabbet grooves, where the glazing points were. These should be sanded down to bare wood to allow you to paint them the same shade as the rest of the frame. After sanding the wood, apply a layer of flax oil. This will help to extend its life.

The next step is to determine the size of the window opening. It is necessary to take horizontal and vertical measurements of the entire opening and also the thickness of the old pane. Subtract 1/8 inch from each measurement to ensure you get a precise size for the new pane. This will also allow for expansion and contraction of the glass in times of seasonal change. Take these measurements to your local hardware or home improvement store, and they will have a piece 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.
