Glass

If your single-pane windows are old damaged, cracked or deteriorating, replacing them with newer glass that is tempered or insulated can increase energy efficiency and decrease noise while also preserving the original character of older homes. The process of replacing a window pane is relatively easy and can be accomplished by most homeowners who possess basic hand tools. In addition to a new pane, the following tools are needed such as latex glazing putty; Glazier's points; pliers and the use of a heat gun to warm the old putty if required. Before starting, wear gloves and safety goggles as working with broken glass could cause injuries.

Remove any broken glass pieces remaining. It is recommended to use pliers for this, but a flathead can work as well. Make use of a wood chisel or putty knife to get rid of any old putty remaining around the frame and window sash. Be careful and slow making sure not to break the current window sash. This should be done on a ladder, not the ground. Also, ensure that someone on the ground to hold it steady.

Prepare the window frame to accommodate the new pane after you have removed the old putty. Measure 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 sent to an hardware or home centers store to have an item cut from stock glass to the right size. Alternatively, you can cut the glass yourself if you have the right tools.

After putting in the new glass, apply some caulking to the edge. This will make the glass weatherproof. Then, place a glazier's tip on each side of the frame to hold the pane in place. The points should not be tight enough to cause friction between the frame and the sash however they should not be loose.

Before applying the putty to the surface, knead thoroughly until it becomes 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 to ensure it's even and smooth.

Glazier's Points

The glazier's facets are small triangular pieces of metal which help to secure glass into the frame of a window without damaging or scratching the delicate surface. It's easy to learn how to use this nefarious tool, and you'll be able to save money on the expense of an expert installation.

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

Take the dimensions of the frame and record precise measurements. Take these dimensions to an hardware store or home center and request that the new pane made slightly smaller than the frame's opening. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Place the new window in the frame and push it into the frame by using your hands. Utilize the chisel's point or the back of the putty blade to tap the glazier's points, as shown in Figure 11. When you're done taping, they should be in line with the top edge of the pane, and the shoulders that are raised of the points should be below the rabbet's lip. groove.

Apply a thin layer of glazing compound to the rabbet grooves and edges of the new glass. This will protect and seal the edges. Allow this to dry and cure fully.

Install the new window sash once the glazing compound has dried. The first step is to coat the wood with a heavy coat of linseed oil. This will stop the new putty from soaking up moisture and deteriorating and cracking over time. Apply the coat using a brush or the tip of your knife, then use the chisel or the back end of the knife to gently hammer the new sash and glazier's points into the grooves of the rabbet. Repeat this process in intervals of 10 inches around the frame.

Putty

A baseball that is thrown, an errant rock or falling branch could cause a window to crack or break. Fortunately, windows can be easily replaced by simply putting a brand new piece in place. The glass is held in place by tiny metal clips known as the glazier's pointed and putty, often called glazing compound. Before installing a replacement pane, first remove the old one and clean up the area with an abrasive and an abrasive scraper that is a pull type or an abrasive wood chisel. Wear gloves and safety glasses when you work. You'll need a heat gun in the event that the window is glued into the frame.

If you are planning to replace your original sash, remove the molding that holds the old pane. Sand the sash until it's flat and ready to receive new caulk. After the sash has been re-installed, apply a new silicone caulk to the glass to ensure it will not leak or change color over time.

Take the glazing points out of the rabbets and the grooves in the sash that the glass sits. If they're hard to chisel, hold an instrument like a heat gun over them to soften first. When using a heat tool, be careful to not damage the sash or its railings.

Create a bed for your new pane by removing the old glaze and putty. Roll a piece of glazing compound between your hands, forming it into a 1/2-inch thick. Press it into the rabbets, where the glass will be placed. The glass replacement windows must be positioned against the putty on both sides. If necessary, lightly tap your 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 before pressing it into the sash. If the crack is not sealed, you will need to use putty to keep water out. Once the putty is dry, wipe the oily film off of the glass and let it dry completely before painting. If you paint before the putty is fully dry, it won't form a solid seal and could leak or discolor over time.

Paint

If you've experienced a broken window pane, you may be worried about the expense of replacing it. The truth is, replacing a single pane of glass doesn't need to be costly when you do it on your own. Even double-paned windows can be replaced for a fraction of the price it will cost a professional.

If you're working with large glass windows first ensure it is securely attached to the frame. With the right tools and techniques, you can accomplish this task fairly easily and quick.

When you are ready to begin, remove the old window pane. Remove the metal glazing points that are attached to it. These are essentially small metal triangles which function as "nails" which hold the window in place within the frame of wood. They are buried beneath a glaze putty or bead that sets to form an unbreakable wedge that holds the wood frame firmly in position and conceals the edges.

After you have removed the old pane removed, clean up the surrounding frame and wood. Scrape off any paint and sand down 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 sanding, apply a layer of flax oil to the wood that is not sanded down to extend the life of the frame.

Next, measure the dimensions of the window opening. It is necessary to measure 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. You can bring these measurements to a hardware store 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 replace window pane causing fogging.
