How to Replace Window Panes

A damaged replacement window panes pane could be a nuisance. It could be a chance to upgrade to energy-efficient windows or insulated ones to enjoy benefits such as improved comfort, increased resale values and reduced utility bills.

You can do it yourself for a fraction of what it would cost to hire an expert. You'll need only the proper tools and a few hours of your time.

Glass

Replace your old single-paned windows using tempered or insulated glass to increase energy efficiency, reduce noise, and preserve the historical integrity of your old home. A majority of homeowners with hand tools can repair windows with ease. You will also need an extra window pane, glazier's suggestions, pliers, windowreplacement and latex glazing putty. If you need to you can use a heating gun to warm the old putty. Wear safety glasses and gloves prior to beginning. Working with broken glass can cause serious injuries.

Remove any broken glass pieces remaining. It is recommended to use pliers however a flathead could be used as well. Then, use a wooden chisel, or putty knife, to take the remainder of the old putty around the frame and the sash. Be careful and slow, taking care not to break the current window sash. It is a good idea to do this using a sturdy ladder rather than on the ground and place someone on the sash to help hold it in place.

Make sure that the window frame is ready to accommodate the new pane after you have removed the old putty. Take measurements of the width and height of the opening for the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to an hardware or home centers store to have an item cut from glass for windows replacement stock to the proper size. You can also cut the glass by yourself if you have the appropriate tools.

After putting the new pane in place, run a small bead of caulking around the edges to ensure it is weatherproof. Install a glazier’s point on both sides of the frame. This will ensure the pane. The points shouldn't be so tight as to cause friction between the sash and frame, but they also should not be too loose.

Before applying the putty on the surface, knead thoroughly until it becomes soft and free from lumps. Roll it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from one corner to another and ensure that it is even and smooth.

Glazier's Points

The glazier's points are small triangular pieces of metal which help to secure the glass into the window frame without causing any damage to the fragile surface. It's simple to learn how to use this hidden tool, and you'll save money on the cost of a professional installation.

After the old putty and glazier's points are removed and the frame is thoroughly cleaned using a utility knife to get rid of any remaining traces. Lightly sand the frame in the rabbet grooves, if necessary, to smooth rough areas. If you sand wood, cover it with painter's tape to avoid accidental damage.

Take the dimensions of the frame and note down precise measurements. Bring these measurements to a hardware store or a home center, and have the new pane made slightly smaller than the frame's opening. This will ensure that the pane fits snugly and allows for expansion and contraction.

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

Apply a small amount 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.

Once the glazing compound has dried it's time to put in the new window sash. First, saturate the wood with a thick coat of Linseed oil. This will prevent the new putty drying out or cracking as it absorbs moisture. Apply the coat using a brush or the tip of your putty knife, then employ the chisel or back end from the putty knife to gently press the new sash and glazier's point into the rabbet grooves. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball that is thrown or a rock that is errant or a falling branch can cause a window pane to break or crack. Fortunately, windows can be repaired by simply putting a new piece in place. The glass is held in the position with a tiny metal clip, called a 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 wood chisel. Wear gloves and safety glasses while working. You'll need a heating gun when the window is fixed into the frame.

If you are planning to replace 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 for a new caulk. After the sash has been reinstalled it is possible to apply a silicone caulk on the glass. This will ensure that it doesn't get soiled or discolor over time.

Take out the glazing points in the rabbets. These are the grooves on the sash, which is where the glass is. If they are hard to cut, place an instrument like a heat gun over them for a few minutes to soften them. If you're using a heated gun, be careful not to scratch the railings or sash by using the tool too closely.

After the old points of glazing and putty have been removed make a bed for the new pane. Roll a piece of glazing compound between your hands, and form it to be about 1/2-inch thick. Then, press it into the rabbets where the glass will be. The glass should rest against the putty on both sides. If necessary, lightly tap your glass into the rabbet with your thumb.

If the new pane is cracked, you can cover it with a solvent-based glue or silicone caulk prior pressing it into the sash. If not, you'll have to apply putty on the crack to create an impervious seal to keep water out. When the putty dries and the film is oily, wipe it off the glass using the help of a rag. Allow it to completely dry before painting. If you paint before the putty has completely dry, it will not form a solid seal and could leak or discolor in time.

Paint

You might be worried about replacing a broken pane of glass. But the truth is that replacing a single glass pane doesn't have to break the bank when you do it yourself. Even a double glazing replacement window-paned window could be replaced for a fraction of what it will cost a professional.

First, if you are working on a large-sized window, ensure that it is securely fastened to the frame. By using the correct tools and techniques to make this task relatively easy and fast.

When you're ready to start taking off the old window pane by removing the glazing points of metal that are connected to it. These are essentially small metal triangles which function as "nails" which hold the window in in the wood frame. They are submerged beneath a layer of glazing putty, which transforms into a solid moulded wedge that secures the window in place and conceals the window's points.

Once you have the old pane taken away, clean up the surrounding frame and wood. Scrape off any paint and sand down the rabbet grooves where the glazing points used to be. These should be sanded to bare wood, so that you can paint them the same color as the rest the frame. After sanding the wood you can apply a layer flax oil. This will help prolong the life of the frame.

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 get the exact size of the new pane subtract 1/8 inch from both measurements. This will also allow for expansion and contraction of the glass during seasonal change. Take these dimensions to a hardware or home improvement store and ask them to cut you 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.
