How to replace window pane window glass replacement Panes

A damaged window pane can be a nuisance. This could be an opportunity to upgrade to energy-efficient windows or insulated ones to enjoy benefits like increased comfort, increased resale value and reduced utility bills.

This is a project you could take on yourself for a fraction of the cost of hiring an expert. It requires the right equipment and an hour or two of your time.

Glass

If your single pane windows are old broken, deteriorating or damaged replacing them with modern glass that is tempered or insulated can increase energy efficiency and reduce noise while also preserving the historic integrity of older homes. Most homeowners with basic hand tools can repair windows with ease. Alongside a replacement pane, the following tools are needed for the replacement process: latex glazing putty Glazier's points; pliers and the use of a heat gun to warm the old putty, if necessary. Before beginning, wear gloves and safety glasses as working with broken glass could cause injuries.

Remove any broken glass pieces that remain. It is recommended to use pliers for this however, a flathead may be useful equally. Then, use a wooden chisel or putty knife to remove the rest of the old putty around the frame and sash. Work slowly and replace window Pane carefully and be careful not to damage the old window replacement panes sash. This is best done on a ladder, not the ground. Also, have someone on the ground to hold it steady.

Make sure the window frame is ready to accept 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. These measurements can be sent to a home center or hardware store to have an item cut from glass stock to the proper size. Alternately, you can cut the glass yourself, if you have the appropriate tools.

After putting the new pane in place After installing the new pane, apply a small amount of caulking along the edge to ensure it is weatherproof. Then install a glazier's point on the frame's opposite side to secure the pane in its place. The points shouldn't be too tight that they create friction between the frame and the sash, but they should also not be loose.

Before applying the putty on the surface, you must knead it thoroughly until it is soft and free from lumps. Then, roll it into pencil-size strips. The first strip should be glued to the frame's corner. Work from one corner to the next and ensure that it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular metal pieces which help to secure the glass to the frame without damaging the delicate surface. It's easy to understand how to use this nefarious tool and you can save money on the expense of a professional installation.

After the old putty as well as glazier's points are removed, thoroughly clean the frame with a utility knife to remove any remaining residue. If needed, lightly sand the wood in the rabbet grooves to smooth rough spots. If you sand wood cover it with painter's tape to avoid accidental damage.

Write down the exact dimensions of the frame. 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 snug fit, and allow for expansion and contraction.

Insert the new pane into the frame and press it down with your hands. Use 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 raised shoulders of the points should be below the rabbet's rim groove.

Apply a thin bead of glazing compound on the edges of the new glass and in the rabbet grooves, to seal and protect them. Allow it to dry and cure completely.

Install the new window sash when 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 sucking in the moisture and drying out and cracking over time. Apply this coat using a brush or the edge of your putty knife, and then use the chisel, or the back end from the putty knife to gently hammer the new sash and glazier's point into the grooves of the rabbet. Repeat this procedure every 10 inches around the frame's perimeter.

Putty

A baseball hit, a rock thrown in error, or a tree falling can cause a broken or cracked window. Fortunately, the majority of windows can be easily replaced by simply putting a new piece in the proper place. The glass is held into the position with a tiny metal clip, called the glazier's point, and putty. This compound is also called glazing compound. Remove the old pane and clean the area with an abrasive, pull-type scraper or wood chisel. Wear protective glasses and gloves while working. If the window is attached to the frame, you'll need to use a heat gun to soften the adhesive prior to taking it off.

If you are planning to install your original sash, remove the molding that holds the old pane. Sand the sash until it's flat and ready for new caulk. After the sash has been re-installed and sanded, apply a fresh caulk made of silicone around the glass to ensure it doesn't swell or fade as time passes.

Take the glazing points out of the rabbets and the grooves in the sash that the glass sits. If they're difficult to chisel, use a hand tool such as a heating gun over them for a few minutes to soften them. When using a heat tool, be sure to not damage the sash's railings and sash.

After the old glazing points and putty are removed, prepare a bed for the new pane. Roll a rope made of glazing compound between your fingers and then make it about 1/2 inch thick. Press it into the rabbets, where the glass will be put. The glass should rest against the putty on both sides. If needed you want to tap your glass lightly into the rabbet with your thumb.

If the new pane is damaged, you can use the silicone caulk or glass glue made from 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 the water out. After the putty has dried and the film is oily, wipe it off the glass with the help of a rag. Allow it to dry completely prior to painting. Paint before the putty has completely dried. It will not make a strong seal and could be leaking or discoloring over time.

Paint

If you've had a broken window pane, you might be concerned about the expense of replacing it. However, replacing one glass pane does not need to cost a fortune when you do it yourself. In fact, even a double-pane window can be replaced at less than the cost of an expert.

If you are working on a large-sized window, make sure that it is securely fixed to the frame. With the right tools and techniques, you can complete this task easily and quick.

When you are ready to begin taking down the old window pane. Remove the metal glazing points attached to it. These are basically small metal triangles which function as "nails" that keep the window in in the wood frame. They are submerged under a bead of glazing putty, which is then cured to form a solid, moulded wedge that holds the window firmly in place and conceals the points.

After you have removed the old pane removed clean the surrounding frame and wood. Scrape off any paint that has been used and sand down the rabbet grooves that the glazing points were. These should be sanded to bare wood to allow you to paint them the same color as the rest the frame. After sanding the wood then apply a layer of flax oil. This will help to extend its life.

Then, take measurements of the dimensions of the window opening. You'll need to take vertical and horizontal measurements of the entire opening, as well as the thickness of the old pane. Subtract 1/8 inch from each measurement to ensure you have the exact size for the new pane. This will allow for seasonal changes in the glass. Take these measurements to the hardware or home improvement store and ask them to cut you 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.
