How to replace window pane Window Panes

A damaged window pane could be a source of frustration. This could be an opportunity to upgrade to energy-efficient windows or insulated ones and enjoy benefits like increased comfort, increased resale values and reduced utility costs.

You can do it yourself for a only a fraction of the cost it would cost to hire an expert. It requires the right tools and only an hour or two of your time.

Glass

replace Window pane your single-paned windows using tempered or insulate glass to improve energy efficiency, reduce noise, and maintain the original character of your old home. The procedure of replacing the window pane is easy and can be accomplished by anyone with basic hand tools. Alongside a replacement pane, the following components are needed such as latex glazing putty; glazier's points; pliers; and the use of a heat gun to warm the old putty, if necessary. Wear safety glasses and gloves prior to beginning. Working with broken glass could result in serious injuries.

Begin by removing any remaining broken pieces of glass. It is best to use pliers however a flathead could be used as well. After that, use a wood chisel or putty knife take the remainder of the old putty around the frame and sash. Be careful to not damage the window sash. Take your time and work slowly. This should be done on an elevated ladder, not on the ground. Also, have someone below the sash hold it steady.

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

Before applying the putty knead it thoroughly until it is smooth and free of lumps. Then you can roll it into pencil-sized strips. The first strip should be glued to the frame's corner. Work from corner to corner and ensure that it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of steel which help to secure the glass to the frame without causing damage to the delicate surface. It's easy to learn how to use this hidden tool, and you'll save money on the expense of an expert installation.

Once the old putty and the glazier's point are gone Clean the frame thoroughly with a knife to get rid of any remaining residue. Lightly sand the wood in the rabbet grooves if needed to smooth rough areas. If you sand wood cover it with painter's tape to prevent accidental damage.

Take measurements of the empty frame and record precise measurements. These measurements can be brought to an hardware or home centers store, and the new frame will be cut a bit smaller. This will ensure a secure fit and leave room for expansion and contraction.

Place the new pane into the frame and push it in using your hands. Make use of the point of the chisel or the back of the putty blade to tap in the glazier's points, as illustrated in Figure 11. The glazier's point should be aligned with the top edge of your pane, and the raised shoulders should be just beneath that lip.

Apply a thin layer glazing compound to the rabbet grooves and edges of the new glass. This will protect and seal the edges. Let it 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 thick coat of Linseed oil. This will keep the new putty from soaking up moisture and drying out and cracking with time. Apply the coating using a brush this coat, or the point of the blade. Then use the chisel that is on the back of the putty tool or the back of the putty handle to gently smash the new sash or glazier's tip into the grooves of the rabbet. Repeat this process every 10 inches around the frame's perimeter.

Putty

A baseball thrown at you, an errant rock or falling branch could cause a window pane to break or crack. Most windows can be replaced easily by simply putting in a fresh piece. The glass is held in place with a small metal clip called the glazier's pointed and putty, which is often called glazing compound. Remove the old pane and clean the area using the rag, a pull-type scraper, or a wood chisel. Wear protective glasses and gloves when you work. 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 molding pieces that are used to secure the old pane. Sand the sash until it is flat and ready to receive new caulk. Once the sash is re-installed then, apply a new silicone caulk to the glass to ensure it won't leak or discolor in time.

Take the glazing points out of the rabbets, the grooves in the sash, where the glass is. If they are hard to chisel, use the hand tool, such as a heatgun over them to allow them to soften before. When using a heating tool, make sure to not scratch the sash's railings and sash.

Once the old points of glazing and putty are removed, prepare a bed for the new pane. Roll a rope with glazing compound between your fingers and make it about 1/2 inch thick. Place it into the rabbets, where the glass will be put. It's important that the glass is positioned against the putty in all places on each side If you have to tap it, gently press the glass into the rabbet using your thumb.

If the new pane is cracked, you can use the silicone caulk or glass glue that is based on solvents to fill in the crack before pressing it in the sash. If not, you'll have to apply putty over the crack to create an impervious seal to keep water out. Once the putty is dry remove the oily film from the glass and allow it to dry completely before painting. Paint after the putty has dried completely. It won't form a good seal and may leak or discolor with time.

Paint

If you've experienced a broken window pane, then you may be worried about the expense of replacing it. However, replacing one glass pane does not have to break the bank if you do it yourself. In fact even windows with double panes can be replaced for replace window pane only a fraction of the cost of a professional.

First, if you are working on a large window, ensure that it is securely attached to the frame. This task can be made relatively simple and quick with the appropriate tools and techniques.

Once you're ready to begin taking off the old window pane by prying out the glazing points made of metal that are attached to it. These are basically small metal triangles which function as "nails" that keep the window in place within the frame of wood. They are submerged under a bead of glazing putty that is then cured to form a solid, formed wedge that holds the window replacements firmly in place and conceals the edges.

After you have removed the old pane removed clean the surrounding frame and wood. Scrape off any paint that has been used and sand the rabbet grooves that the glazing points were. Sand them down to clean wooden surfaces so you can paint the frames with the same shade. After the sanding process, apply a coat of flax oil to the bare wood to prolong its life.

Next, measure the dimensions of the window opening. You will need to measure the horizontal and vertical dimensions of the entire opening as well as the thickness. Subtract 1/8 inch from each measurement to ensure you get the exact measurement 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 cut the glass 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.
