How to Replace Window Panes
A damaged or cracked window can be a nuisance. This could be an opportunity to upgrade to energy-efficient windows or insulated ones, and reap benefits such as improved comfort, increased resale value and reduced utility costs.
You can do it yourself for a less than what it would cost to employ an expert. You only need the right tools and a few hours of your time.
Glass
If your single-pane windows are old broken, deteriorating or damaged, replacing them with newer glass that is tempered or insulated will improve energy efficiency and reduce noise while also preserving the original character of older homes. Most homeowners with basic hand tools can replace window pane windows with ease. Alongside a replacement pane, the following components are needed for the replacement process: latex glazing putty pliers, glazier’s points and an electric heater to warm the old putty, if necessary. Wear safety goggles and gloves prior to starting. Working with broken glass can cause serious injuries.
Take out any broken glass pieces remaining. It is best to use pliers for this, but a flathead can be used as well. Use a wood chisel, or putty knives to remove any old putty remaining around the frame and the window sash. Take your time and work slowly, taking care not to damage the old window sash. It is best to do this on a stable ladder rather than the ground and to have someone stand below the sash in order to help hold it in place.
Prepare the window frame to accommodate the new pane when you have removed the old glue. Take measurements of 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). Take these measurements to an hardware store or home center and have a piece of stock glass cut to size. You can also cut the glass by yourself if you have the appropriate tools.
After putting the new pane in place after installing the new pane, put a tiny amount of caulking around the edges to make it weatherproof. Then install a glazier’s point on each side of the frame to hold the pane in the right place. The points should not be too tight that they cause friction between the frame and sash However, they should not be loose.
Before applying the putty to the surface, knead thoroughly until it is smooth and free from lumps. Roll it into pencil-sized strips. Place the first strip in the corner of the frame, moving from one corner to another so that it is even and smooth.
Glazier’s Points
The glazier’s facets are small triangular pieces of metal that help secure glass into the frame of a window without damaging or scratching the delicate surface. Knowing how to use these hidden tiny pieces of help is simple and could save you money on professional installation or the cost of buying new glass.
After the old putty and glazier’s points are removed, thoroughly clean the frame with a utility knife to get rid of any remaining traces. Lightly sand the frame in the rabbet grooves, if necessary, to smooth out 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. Take these dimensions to an hardware store or home center, and have the new pane made slightly smaller than the frame’s opening. This will ensure a secure fit, and allow for expansion and contraction.
Place the new window in the frame and Replace window pane press it in place using your hand. Utilize the chisel’s point, or the edge of the putty blade to smudge the glazier’s points as shown in Figure 11. The glazier’s point should be flush against the top edge of the pane and the shoulders should be just below that lip.
Apply a thin layer glazing compound on the rabbet grooves and the edges of the glass. This will protect and seal the edges. Allow this to dry and cure completely.
After the glazing compound dries, you’re ready to install the new window sash. First, coat the wood with a thick coat of linseed oil. This will prevent the new putty from soaking up moisture and drying out and cracking with time. Apply this coat with a brush or the tip of your putty knife, and then use the chisel or the back end of the putty knife to gently hammer in the new sash and glazier’s point into the rabbet grooves. Repeat this process in intervals of 10 inches all around the frame.
Putty
A baseball that is thrown or a rock that is errant or falling branch could cause a window to crack or break. The majority of windows can be replaced by simply putting in a fresh piece. The glass is held in place by tiny metal clips known as the glazier’s pointed and putty, which is often called glazing compound. Before you install a new pane, first take out the old one and clean the area with an abrasive and an abrasive scraper that is a pull type or the wood chisel. Wear safety glasses and gloves while working. You’ll require a heat gun in the event that the window is glued to the frame.
If you’re planning to install your original sash, remove the mold that holds the old pane. Then you can sand the sash down to ensure it’s level and ready to be re-caulked. After the sash has been installed then, you can apply a silicone caulk over the glass. This will ensure that it won’t be leaking or fade over time.
Take the glazing points out of the rabbets, or the grooves in the sash that the glass sits. If they’re difficult to chisel, use an instrument such as a heatgun over them to soften first. If you’re using a heating gun, be cautious not to scratch the railings of the sash or the sash itself by placing the tool too closely.
Create the bed for your new pane by removing the old putty and glazing points. Roll a piece of glazing compound between your hands, and form it into a 1/2-inch thick. Press it into the rabbets, where the glass will be put. It’s important that the glass sits on the putty on each side If you have to tap it, gently press the glass into the rabbet using your thumb.
If the new pane has a crack, you can cover it with a solvent-based glue or silicone caulk before pressing it into the sash. If the crack isn’t sealed, you’ll need to apply putty to keep water from getting in. Once the putty is dry, wipe the oily film from the glass and let it dry completely before painting. If you paint before the putty is fully dry, it won’t form an effective seal and could leak or discolor in time.
Paint
You might be worried about replacing a broken pane of glass. However, replacing one glass pane does not have to break the bank if you do it yourself. Even a double-paned window replacements could be replaced for a fraction of the price it will cost an expert.
If you are working on a large window, make sure that it is securely fastened to the frame. By using the correct tools and techniques to complete this task easily and quick.
When you are ready to begin, remove the old window pane. Take out the glazing points made of metal that are attached to it. They are basically tiny metal triangles that function as “nails” which hold the window in place within the frame of wood. They are submerged beneath a layer of glazing putty that transforms into a solid moulded wedge which holds the window in place and conceals the edges.
Once you have the old pane taken away clean the surrounding frame and wood. Scrape off any paint and sand down the rabbet grooves, where the glazing points used to be. Sand them down to bare wooden surfaces, allowing you to paint the frames with the same shade. After sanding, apply a coat of flax oil to the bare wood to help extend its lifespan.
The next step is to determine the width of the window’s opening. You will need to take horizontal and vertical measurements of the entire opening as well as the thickness of the old pane. To determine the exact size of the new pane subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. Take these measurements 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.
