How to Replace Window Panes

A damaged window pane can be an inconvenience. It could also be a chance to upgrade your glass to energy-efficient or insulated windows, and enjoy benefits such as more comfort, higher the value of resales and repairmywindowsanddoors lower utility bills.

You can do it yourself at a fraction of what it would cost to employ an expert. You'll only require the appropriate tools and a few minutes of your time.

Glass

Replace your old single-paned windows with tempered or insulation glass to improve the efficiency of your energy, reduce noise, and maintain the historical integrity of your old home. The replacement of the window handles replacement pane is easy and can be accomplished by anyone with basic hand tools. You'll also require a replacement window pane, glazier's tips, pliers, and latex glaze putty. If needed, you can use a heatgun to warm the old putty. Before beginning, wear gloves and safety glasses as working with broken glass can cause injuries.

Begin by removing any remaining broken pieces of glass. This can be done with the help of pliers though using a flathead screwdriver can also be effective in a pinch. Then, use a wooden chisel or putty knife take the remainder of the old putty around the frame and sash. Work slowly and carefully making sure not to break the current window sash. It is a good idea to do this on a sturdy ladder rather than on the ground, and to have someone standing below the sash to help keep it in place.

Make sure that the window frame is ready to accommodate the new pane after you have removed the old glue. To allow for seasonal expansion or contraction by subtracting 1/8 inch from the measurements of width and height. Take these measurements to an hardware store or home center, and find a piece glass cut to size. Alternately, you can cut the glass yourself if have the appropriate tools.

After installing the new pane, 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 help secure the pane. The points shouldn't be too tight as to cause friction between the sash and frame however they shouldn't be loose.

Before applying the putty work it in a gentle manner until it's soft and free of lumps. Roll it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from one corner to the next and ensure that it is even and smooth.

Glazier's Points

The glazier's facets are tiny triangular pieces of steel that allow glass to be secured into a window frame without scratching or damaging the fragile surface. It's easy to understand how to use this secret tool and you can save money on the expense of an installation by a professional.

Once the old putty and the glazier's points have been removed Clean the frame thoroughly using a utility knife to remove any remaining residue. Lightly sand the wood in the rabbet grooves, if necessary, to smooth out rough areas. If you decide to sand wood, protect it with painter's tape to protect it from damage caused by accidental sanding.

Take measurements of the empty frame and note down precise measurements. Take these measurements to a hardware store or home center and request that the new pane cut slightly smaller than the frame's opening. 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 the frame with your hand. Use the chisel's point or the back of the putty knife to tap the glaziers' points as shown in Figure 11. The glazier's points should sit flush against the top edge of your pane, and the shoulders should be just below the lip.

Apply a thin layer of glazing compound on the edges of the new glass and into the rabbet grooves, to seal and protect them. Let it dry and cure fully.

Install the new window sash when the glazing compound has dried. First, saturate the wood with a thick coat of Linseed oil. This will stop the new putty from drying out and cracking due to the moisture it absorbs. Apply the coating using a brush this coat, or even the tip of the blade. Then use the chisel that is on the back of the tool or the back of the putty handle to gently hammer the new sash or glazier's point into rabbet grooves. Repeat this process every 10 inches around the frame's perimeter.

Putty

A baseball thrown, a rock thrown in error or a branch falling can result in a cracked or cracked window. Fortunately, windows can be easily replaced by simply placing a new piece of glass in its the proper place. The glass is held into the position with a tiny metal clip, referred to as the glazier's point, and putty. This compound is also known as glazing compound. Before you install a new pane, first remove the old one and clean the area with the help of a rag, the pull-type paint scraper or the wood chisel. Wear safety glasses and gloves while working. If the window is secured to the frame, you'll need use a heat gun to soften the adhesive before cutting it loose.

If you are planning to replace your original sash, remove the molding that supports the old pane. Sand the sash until it is flat and ready to receive new caulk. Once the sash is installed then, apply a new silicone caulk to the glass to ensure it will not leak or change color as time passes.

Take out the glazing points in the rabbets. These are the grooves in the sash, which is where the glass is. If they're hard to chisel, use the hand tool, like a heat gun over them to allow them to soften before. If you're using a heated gun, be cautious not to damage the sash or its railings by placing the tool too closely.

Make the bed for your new pane after you have removed the old putty and glazing points. Roll a rope made of glazing compound between your fingers, and make it around 1/2 inch thick. Then, push it into the rabbets, where the glass will rest. It is essential that the glass is positioned against 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 is cracked then you can seal it with a solvent-based glass glue or silicone caulk before pressing it into the sash. In other cases, you'll need to apply putty over the crack to create an impervious seal to keep water out. When the putty dries then clean the oily film off the glass with an abrasive and allow it to dry completely before painting. Paint before the putty has completely dried. It will not make a strong seal and may leak or discolor with time.

Paint

If you've had a broken window pane, you may be concerned about the expense of replacing it. In reality, replacing a single pane of glass doesn't need to be costly even if you do it your own. Even double-paned windows can be replaced for a fraction of the price it costs an expert.

If you're working with a large glass window first, ensure that it is securely attached to the frame. This can be made relatively simple and fast with the proper tools and techniques.

If you're ready to begin, begin by removing the old window by prying out the glazing points of metal that are attached to it. These are basically small metal triangles that function as "nails" which hold the window in place in the wood frame. They are buried beneath a layer of glazing putty that is then cured to form a solid, moulded wedge that secures the window in place and hides the edges.

After removing the old pane, clean the frame and the wood. Scrape off any paint that has been used, and sand the rabbet grooves in which the glazing points were. They should be sanded to bare wood, so that you can paint them the same color as the rest the frame. After the sanding process, apply a coat of flax oil to the wood's surface to prolong its life.

Next, measure the dimensions of the window's opening. It is necessary to take vertical and repairmywindowsanddoors horizontal measurements of the entire opening, as well as the thickness of the old pane. To determine 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 in times of seasonal change. You can take these measurements to a hardware or home improvement store and have 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.
