How to replace window pane Window Panes

A damaged window pane can be an issue. This could be an opportunity to upgrade to energy-efficient windows or insulated ones to enjoy benefits like increased comfort, increased resale values and lower utility costs.

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

Glass

If your single-pane windows are outdated broken, deteriorating or damaged, replacing them with newer glass that is tempered or insulated can increase energy efficiency and decrease noise while also preserving the historic integrity of older homes. The replacement of the window pane is easy and can be accomplished by most homeowners who possess basic hand tools. In addition to a replacement pane, the following components are needed for the replacement process: latex glazing putty glazier's points; pliers; and a heat gun for warming the old putty if required. Before starting, put on protective gloves and goggles since working with broken glass could cause injuries.

Take away any broken glass pieces that remain. It is recommended to use pliers however, a flathead may be useful equally. Make use of a wood chisel or putty knives, Replace Window pane to take away any remaining old putty around the frame and the window sash. Take your time and work slowly making sure not to damage the old window sash. It is best to work using a sturdy ladder rather than the ground and to have someone stand below the sash to help keep it steady.

Prepare the window frame to receive the new pane when you have removed the old glue. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. These measurements can be taken to an hardware or home centers store to have cut a piece of glass that is in stock to the correct size. You can cut the glass yourself if you possess the appropriate tools.

After installing the glass, apply a small amount of caulking to the edge. This will make the glass weatherproof. Then, you can install a glazier's pointing on each side of the frame to secure the pane in the right place. The points shouldn't be so tight that they cause friction between the frame and the sash However, they should not be loose.

Before applying the putty on the surface, knead thoroughly until it is smooth and free from lumps. Then make it into pencil-sized strips. Apply the first strip 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 points are tiny triangular metal pieces that allow glass to be secured into the window frame without causing damage to the delicate surface. Learning how to use these hidden little helpers is easy and could save you money on professional installation or the cost of purchasing new glass.

After the old putty as well as the glazier's points have been removed, thoroughly clean the frame with a knife to eliminate any remaining residue. If needed it is necessary to lightly sand the wood along grooves of the rabbets to smooth out rough spots. If you do sand your wood, ensure you protect 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 a home center and request that the new pane made slightly smaller than the frame's opening. This will ensure a tight fit, and allow for expansion and contraction.

Place the new pane in the frame and push firmly with your hands. Utilize the point of the chisel or the back of the putty knife to smudge the glazier's points as illustrated in Figure 11. When you're done, they should be flush with the top edge of the pane, and the shoulders of the points should be just below the rabbet's rim groove.

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

Once the glazing compound has dried and the glazing compound is dry, you can install the new window sash. First, saturate the wood with a thick coat of linseed oil. This will stop the new putty drying out or cracking as it absorbs moisture. Use a brush to apply this coat, or the tip of the putty blade. Then use the chisel on the back of the tool or the back of the putty handle to gently hammer the new sash or glazier's point into grooves of the rabbet. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball thrown or a rock thrown in error, or a tree falling could result in a broken or cracked window pane. The majority of windows can be replaced by putting in a new piece. The glass is held in place using tiny metal clips known as a glazier's point, and putty, also called glazing compound. Remove the old pane and clean the area with the rag, a pull-type scraper or wood chisel. Wear safety glasses and gloves while working. If the window is glued to the frame, you'll have to make use of a heat gun to soften the adhesive prior to cutting it loose.

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

Take the glazing points out of the rabbets and the grooves in the sash where the glass is. If they're difficult to chisel, hold a hand tool such as a heatgun over them for a few minutes to soften them. When using a heat tool, be careful to not damage the sash or its railings.

Create a bed for your new pane after removing the old glaze and putty. Roll a piece of glazing compound between your hands, shaping it to be around 1/2-inch thick. Place it into the rabbets where the glass will be placed. It's important that the glass sits on the putty on each side If you have to do so, gently tap the glass into the rabbet with your thumb.

If the new pane has a crack you can fill it with a solvent-based glass glue or silicone caulk prior pressing it into the sash. In other cases, you'll need to putty over the crack to form an airtight seal and keep water out. After the putty has dried, clean the oily film off the glass using an abrasive and allow it to dry completely prior to painting. Paint before the putty is completely dry. It won't form a good seal and could discolor or leak over time.

Paint

You might be worried about replacing a broken piece of glass. But the truth is that replacing a single glass pane doesn't need to cost a fortune if you do it yourself. In fact even windows with double glazed window replacement panes can be replaced for less than the cost of a professional.

First, if you are working on a large window, make sure that it is securely attached to the frame. By using the correct tools and techniques you can accomplish this task fairly easily and speedy.

If you're ready to begin, begin by removing the old window by removing the metal glazing points that are attached to it. These are small metal triangles which act as "nails", holding the window in the frame. They are submerged beneath a glaze putty or bead that hardens to solid wedge which holds the wood frame firmly in position and conceals the edges.

After taking off the old pane clean the frame and wood. Scrape off any paint that has been used and sand the rabbet grooves in which the glazing points were placed. They should be sanded to bare wood, to allow you to paint them the same color as the rest the frame. After the sanding process, apply a coat of flax oil on the wood that is not sanded down to prolong its life.

Then, you need to measure the size of the window opening. It is necessary 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 that you have the exact size for the new pane. This will allow for seasonal changes in the glass. You can bring these measurements to a hardware store 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.
