Remove any broken glass pieces that remain. It is best to use pliers for this, but a flathead can work as well. Make use of a wood chisel or putty knives, to take away any old putty remaining around the frame and window sash. Be careful not to break the window sash. Work slowly and carefully. It is best to work on a sturdy ladder instead of the ground and place someone on the sash to help hold it in place.

Once you have removed all the old putty, prepare the window frame to fit the new pane. To allow replacement handles for upvc windows seasonal expansion or contraction, subtract 1/8 inch each from the measurements of width and height. Take these measurements to the nearest hardware store or home center and get a piece of stock glass cut to size. You can also cut the glass yourself if 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 seal it against weather. Then install a glazier's point on each side of the frame to hold the pane in the right place. The points should not be tight enough to create friction between the frame and the sash, but they should also not be loose.

Before applying the putty on the surface, knead thoroughly until it is smooth and free of lumps. Then, roll it into pencil-size strips. The first strip should be glued to the frame's corner. Work from one corner to another 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 into the window frame without causing any damage to the fragile surface. Learning how to use these hidden tiny pieces of help is simple and can save you money on a professional installation or the cost of purchasing new glass.

After removing the old putty, glazier points as well as any remaining residue, clean the frame thoroughly using an utility knife. If necessary it is necessary to lightly sand the wood in the grooves of the rabbet to smooth rough spots. If you do sand the wood, make sure to protect it with painter's tack to avoid accidental damage.

Write down the dimensions of the frame. These dimensions can be taken to an hardware or home centers store and the new pane will be cut slightly smaller. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new pane into the frame and press it into place firmly by using your hands. Then, use the tip of your chisel, or the back end of the putty knife to pierce the glazier's facets, as shown in Figure 11. The glazier's points should sit flush against the top edge of your pane and the shoulders raised should be just beneath that lip.

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

Install the new window sash when the glazing compound has dried. First, you need to coat the wood with an even layer of linseed. This will prevent the new putty from taking up moisture and deteriorating and cracking over time. Use a brush to apply this coat, or even 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 tip into the rabbet grooves. Repeat this process at intervals of 10 inches all around the frame.

Putty

A baseball thrown at you, an errant rock or a falling branch can cause a window to break or crack. Most repair my windows And doors can be replaced by putting in a new piece. The glass is held in the position with a tiny metal clip, called the glazier's point, and putty. This compound is also referred to as glazing compound. Remove the old pane and clean the area with a rag, a pull-type scraper, or a wood chisel. Wear protective glasses and gloves while doing this work. You'll need a heating gun if the window is glued to the frame.

If you're planning to install the original sash in the future, take care to remove any pieces of molding that are used to secure the old pane. Then, sand the sash to make sure it's flat and ready to be re-caulked. After the sash has been re-installed then, apply a new caulk made of silicone around the glass to ensure that it doesn't swell or fade in time.

Remove the glazing points from the rabbets, or the grooves in the sash that the glass is. If they are hard to chisel, hold a hand tool like a heat gun over them to allow them to soften before. If you're using a heat gun, make sure not to cause damage to the railings or sash by holding the tool too closely.

Make the bed for your new pane after removing the old putty and glazing points. Roll a rope of glazing compound between your hands, shaping it to be about 1/2-inch thick. Place it into the rabbets, where the glass will be put. The glass must rest against the putty on both sides. If you need to you want to tap your glass lightly into the rabbet using your thumb.

If the new pane has a crack then you can seal it with a solvent-based glass glue or silicone caulk before pressing it into the sash. Otherwise, you'll need to putty over the crack to create a tight seal and keep water out. After the putty is dry then clean the oily film off the glass with the help of a rag. Allow it to dry completely prior to painting. If you paint before the putty is fully dry, it won't create an effective seal and could be leaking or discoloring over time.

Paint

If you've experienced a broken window pane, you might be worried about the expense of a new one. But the truth is that replacing a single glass pane doesn't require a huge amount of money when you do it yourself. In fact, even a double-pane window can be replaced at only a fraction of the cost of a professional.

First, if you're working on a large-sized window, make sure it is securely attached to the frame. This job is relatively easy and fast using the proper tools and techniques.

When you are ready to begin with the removal of the window pane. Remove the glazing points made of metal that are attached to it. These are tiny metal triangles that function as "nails" that hold the window within the frame. They are buried beneath a layer of glazing putty, which transforms into a solid moulded wedge which holds the window in place and hides the points.

After removal of the old pane clean the frame and wood. Scrape off any old paint and sand down the rabbet grooves in which the glazing points were placed. Sand them down to clean wooden surfaces, allowing you to paint the frames the same shade. After sanding the wood you can apply a layer flax oil. This will help extend its life.

The next step is to measure the dimensions of the window opening. You will need to take horizontal and vertical measurements of the entire opening, and also the thickness of the old pane. To get the exact size of the new pane, subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. You can take these measurements to a hardware or home improvement shop and get 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.
