Glass

If your single pane windows are old, deteriorating or broken replacing them with more modern glass that is tempered or insulated can increase energy efficiency and reduce noise while maintaining the original character of older homes. The majority of homeowners with basic hand tools can replace windows with ease. You will also need an additional window pane, glazier's tips, repaired pliers, and latex glazing putty. If you need to 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 remaining. It is best to use pliers however a flathead could be used equally. After that, use a wood chisel or repaired putty knife remove the rest of the old putty around the frame and sash. Be careful to not damage the window sash. Be careful and slow. This can be done best on a ladder, not the ground. Also, have someone below the sash ensure it is held steady.

Make sure the window frame is ready to accommodate the new pane after you have removed the old glue. 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 a piece cut of glass stock to the proper size. You can cut the glass yourself if you possess the appropriate tools.

After installing the new pane After installing the new pane, apply a small amount of caulking around the edges to make it weatherproof. Install a glazier’s point on both sides of the frame. This will help secure the pane. The points shouldn't be so tight that they cause friction between the sash and frame but they should not be too loose.

Before applying the putty, work it in a gentle manner until it is soft and free of lumps. Then make it into pencil-sized strips. The first strip should be placed to the corner of the frame, working from one corner to another so that it is even and smooth.

Glazier's Points

The glazier's points are small triangular pieces which help to secure glass into a window frame without scratching or damaging the delicate surface. Understanding how to use these tiny pieces of help is simple and could save you money on a professional installation or the cost of buying new glass.

Once the old putty and the glazier's points have been removed and the frame is thoroughly cleaned with a knife to remove any remaining residue. Lightly sand the frame in the rabbet grooves, if necessary, to smooth rough areas. If you do sand your wood, make sure to protect it by using painter's tape to prevent accidental damage.

Take measurements of the empty frame and record precise measurements. Take these measurements to a hardware store or home center, and have the new pane made slightly smaller than the frame's opening. This will ensure a secure fit and leave room for expansion and contraction.

Place the new pane in the frame and press it down with your hands. Use the point of the chisel or the back of the putty knife to smudge the glaziers' points as shown in Figure 11. When you're done, they should be in line with the top edge of the pane. the shoulders that are raised of the points should be just below the lip of the rabbet groove.

Apply a thin layer glazing compound to the rabbet grooves and edges of new glass. This will protect and seal the edges. Let it dry and cure completely.

After the glazing compound dries, you're ready to install the new window sash. First, saturate the wood with a heavy coat of linseed oil. This will stop the new putty from soaking up the moisture and drying out and cracking with time. Apply the coating using a brush this coat, or the tip of the putty blade. Then use the chisel on the back of the tool or the back of the putty handle to gently hit the new sash, or glazier's tip into the grooves of the rabbet. Repeat this process in intervals of 10 inches around the frame.

Putty

A hurled baseball, an errant rock or a fallen branch can cause a window to crack or break. Most windows can be repaired easily by simply putting in a fresh piece. The glass is held in place using small clips made of metal called the glazier's pointed and putty, also called glazing compound. Before installing a replacement double glazed window pane, first get rid of the old one and clean the area using a rag and the pull-type paint scraper or the wood chisel. Wear gloves and safety glasses when working. You'll require a heat gun in the event that the window is glued into the frame.

If you are planning to reinstall the original sash, take off the mold that holds the old pane. Then, sand the sash to ensure it's level and ready for a new caulk. After the sash has been re-installed and sanded, apply a fresh silicone caulk around the glass to ensure it will not leak or change color over time.

Take out the glazing points in the rabbets. These are the grooves in the sash, where the glass is. If they're hard to chisel, hold the hand tool, like a heat gun over them to soften first. If you're using a heat gun, make sure not to damage the railings of the sash or the sash itself by holding the tool too closely.

After the old points of glazing and putty have been removed prepare a bed for the new pane. Roll a rope of glazing compound between your hands, and form it into a 1/2-inch thick. Press it into the rabbets where the glass will be put. It is essential that the glass is positioned against the putty on both sides, so if you need to, lightly tap the glass into the rabbet using your thumb.

If the new pane is damaged, you can use the silicone caulk or glass glue based on solvents to seal the crack before pressing it in the sash. If the crack is not sealed, you'll need to use putty to keep water out. When the putty dries then clean the oily film off the glass with a rag and allow it to completely dry before painting. Paint after the putty has completely dried. It will not form a good seal and may leak or discolor with time.

Paint

If you've had a broken window pane, you might be worried about the cost of replacing it. The truth is, replacing a single pane of glass doesn't need to be expensive even if you do it your own. Even double-paned windows can be replaced for a fraction of the price it will cost an expert.

If you're working with a large glass window, first make sure it is securely fixed to the frame. By using the correct tools and techniques you can complete this task easily and quick.

When you are ready to start with the removal of the window pane. Remove the glazing points made of metal that are attached to it. These are tiny triangles of metal that function as "nails" that hold the window within the frame. They are submerged beneath a glaze putty or bead that sets to form a solid wedge that holds the frame firmly in position and hides the points.

After removing the old pane, clean the frame and the wood. Scrape off any old paint and sand the rabbet grooves where the glazing points were. Sand them down to clean wood surfaces, so that you can paint the frames the same shade. After the sanding process, apply a coat of flax oil on the wood's surface to prolong its life.

Next, measure the dimensions of the window opening. You'll need to determine the horizontal and vertical dimensions of the entire opening as well as the thickness. To determine the exact size of the new pane subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. Bring these measurements to your local hardware or home improvement store and ask them to cut you cut the glass for you.

Now, it's time to bed the new window glass replacement 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.
