How to replace Window pane Window Panes

A cracked window pane can be a nuisance. It could also be an opportunity to upgrade your glass to energy-efficient or insulated windows to benefit from more comfort, higher the value of resales and lower utility costs.

It's a task you can tackle yourself at only a fraction of the cost of hiring a professional. You'll need only the right tools and a few minutes 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 will increase energy efficiency and reduce noise while maintaining the historical integrity of older homes. The replacement handles for upvc windows of a window pane is relatively simple and can be done by homeowners with basic hand tools. You will also require an extra window pane, glazier's tips, pliers, and latex glaze putty. If necessary you may make use of a heat gun to warm the old putty. Before starting, put on gloves and safety goggles as working with broken glass can cause injuries.

Take out any broken glass pieces remaining. It is recommended to use pliers for this however, a flathead may work as well. Make use of a wood chisel or putty knives to remove any old putty remaining around the frame and window sash. Be careful not to damage the window sash. Take your time and work slowly. It is best to do this on a sturdy ladder rather than on the ground and have someone standing below the sash to help keep it in place.

Once you've removed all the old putty, prepare the window frame for the new pane. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of the width and height. These measurements can be taken to a home center or hardware store to get cut a piece of glass that is in stock to the correct size. You can also cut the glass yourself if you have the appropriate tools.

After installing the glass, Replace Window Pane apply caulking around the edge. This will make the glass weatherproof. Then, you can install a glazier's pointing on the frame's opposite side to hold the pane in place. The points shouldn't be too tight that they cause friction between the sash and the frame, but they also shouldn't be too loose.

Before applying the putty on the surface, gently knead it until it becomes soft and free of lumps. Then you can roll it into pencil-sized strips. Apply the first strip to the frame's corner. Work from one corner to the next to ensure it's even and smooth.

Glazier's Points

The glazier's points are the small triangular pieces of metal that help secure glass into the frame of a window without scratching or damaging the fragile surface. Learning how to use these little helpers is easy and can save you money on professional installation or the cost of new glass.

Once the old putty and the glazier's point are gone and the frame is thoroughly cleaned using a utility knife to remove any remaining residue. Lightly sand the wood into 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.

Note down the dimensions of the frame. Take these dimensions to a hardware store or a home center and request that the new pane cut smaller than the frame's opening. This will ensure a secure fit, and allow for expansion and contraction.

Insert the new pane into the frame and push it in with your hands. Then, use the tip of your chisel, or the back end of the putty knife to pierce the glazier's facets, as shown in Figure 11. The glazier's points should sit flush against the top edge of your pane and replace window pane the shoulders raised should be just below the lip.

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

Install the new window sash once the glazing compound has dried. First, you need to coat the wood with a thick layer of linseed. This will stop the new putty from drying out and cracking as it absorbs moisture. Apply this coat with a brush or the edge of your putty knife, and then employ the chisel or back end of the putty knife to gently hammer the new sash and glazier's point into the rabbet grooves. Repeat this process at intervals of 10 inches all around the frame.

Putty

A baseball hit or a rock thrown in error, or a fallen tree can cause a broken or cracked window. The majority of windows can be replaced by putting in a new piece. The glass is held in position by a small metal clip, called a glazier's point and putty. This compound is also known as glazing compound. Remove the old pane and clean the area using a rag, a pull-type scraper, or a wood chisel. Wear safety glasses and gloves while doing this work. You'll need a heating gun when the window is fixed into the frame.

If you are planning to install your original sash, you must remove the molding that supports the old pane. Sand the sash until it is flat and ready for new caulk. After the sash has been re-installed and sanded, apply a fresh silicone caulk to the glass to ensure it won't leak or discolor as time passes.

Remove the glazing points from the rabbets and the grooves in the sash that the glass sits. If they're difficult to chisel, hold a hand tool like a heat gun over them to allow them to soften before. If you're using a heated gun, make sure not to scratch the railings or sash by using the tool too tightly.

Make a bed for your new pane after you have removed the old putty and glazing points. 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 is crucial that the glass rests against the putty in all places on each side If you have to do so, gently tap the glass into the rabbet using your thumb.

If the new pane is cracked you can fill it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash. If the crack isn't sealed, you'll need to use putty to keep water out. After the putty has dried remove the oily film off the glass and allow it to dry completely before you paint. If you paint before the putty is completely dry, it won't form a solid seal and could be leaking or discoloring in time.

Paint

You may be concerned about replacing a broken pane of glass. The truth is, replacing a single pane glass doesn't need to be costly if you do it on your own. In fact even windows with double panes can be replaced at a fraction of the cost of an expert.

First, if you are working on a large window, make sure that it is securely fixed to the frame. Using the proper tools and techniques you can complete this task easily and quick.

When you are ready to start taking down the old window pane. Remove the glazing points made of metal that are attached to it. These are tiny triangles of metal which act as "nails" that hold the window in the frame. They are placed beneath a layer of glazing putty, which transforms into a solid moulded wedge which holds the window in place and conceals the window's points.

After removing the old pane, clean the frame and wood. Scrape away any old paint and sand down the rabbet grooves, where the glazing points were. They should be sanded to bare wood, so that you can paint them the same shade as the rest of the frame. After sanding, apply a coat of flax oil on the wood's surface to extend the life of the frame.

Then, you need to measure the size of the window's opening. You'll need to take horizontal and vertical measurements of the entire opening as well as the thickness of the old pane. 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. Take these dimensions to your local 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.
