Introduction
When replacing a pane of glass in a window, it’s important to use tempered glass which you can find at glass company near me. If you’re replacing just a small section of the window pane, then you don’t need to remove the sash and molding—just measure the new piece of glass and insert it into the frame. You may want to remove the sash if you’re replacing an entire window pane or if your window is older and doesn’t have a mullion that separates each individual pane from its neighbor.
Step 1: Remove Putty
To begin, remove the putty from your window. This is done by either using a putty knife or a putty scraper (pictured above) to scrape off all of the old caulk and residue. Be careful not to damage any woodwork around your window frame! Next, clean away any dust that may have been created during this process with a damp cloth or paper towel.
Now that you’ve removed all traces of old caulk, it’s time for step two: installing new pane-sealing putty!
Step 2: Pry Off Molding
The next step is to remove the window’s molding. This can be done by using a pry bar, flathead screwdriver, hammer, chisel, crowbar or hacksaw. A crowbar is best for this job because it has a sharp point that makes it easy to get through the glass and into the frame of your window. If you don’t have access to a crowbar or other tools that can help you break apart your window without risking damage to its framing elements then you may need to take another route.
If you’re comfortable with operating power tools and have access to them then breaking down your window panes with a saw can be an effective method for getting rid of them quickly and easily while ensuring they don’t fall back into place after being removed from their original spot on your home’s exterior walls (or inside). Using this method requires having some type of saw blade which will allow you cut through both sides at once so there’s no risk involved with damaging anything else in its path as long as all precautions are taken beforehand such as wearing protective eye gear when operating machinery like these types tend towards having accidents occur when handled improperly).
Step 3: Remove Sash
Once you’ve removed all the nails, it’s time to remove any remaining glass. The sash is usually held in place by a locking mechanism (sometimes referred to as a stop), which is typically made from wood or metal. To remove it, you’ll want to pry up on its edge with a chisel or similar tool. Make sure not to damage the frame of your window when doing this—you don’t want to have to replace that too!
If you have a double-hung window, both upper and lower sashes can be removed at this point: simply use your chisel and hammer combination again on each side of each sash until they’re free from their respective frames. If you have casement windows, just remove one side at first; once that side is out of the way (using your hammer and chisel combo), do the same thing for whichever other side still needs replacing.
Step 4: Clean Edges of Glass & Frame
The next step is to clean the edges of both glass and frame. If necessary, use a razor blade to remove any remaining putty or caulk around the edge. Then use pliers to scrape off any old caulking from around the frame and window sill.
If your window has an aluminum frame instead of wood, use sandpaper along with a scraper or wire brush attachment for your drill to clean it thoroughly before moving on to Step 5: Reinstalling Glass & Frame
Step 4a: If You’re Replacing the Entire Window Pane
If you’re replacing the entire pane of glass, use a glass cutter to score the edges. Then use a hammer and chisel to break it along that line. Use a file or sandpaper to clean up any rough edges created by scoring or breaking the glass. Use a putty knife to scrape off any old putty or resin around the inside edge of where your new pane will go.
Step 4b: If You’re Replacing Only Part of Your Window Pane
For instance, if you have one broken corner in an otherwise intact window pane, follow these steps instead:
Step 5: Insert New Glass
- Insert the new glass into the window frame.
- First, clean up any dirt or debris around the window frame using a vacuum cleaner. Then, use a putty knife to gently tap in the new pane of glass into place. Make sure that there are no shards of broken glass on either side of your new pane; if there are any pieces still stuck to other parts of your window, carefully remove them with a razor blade or small screwdriver before inserting your new pane back into place.
- Once you’ve successfully inserted all four sides of your replacement window pane, use a rubber mallet to tap it securely into place so that there is no wiggle room between it and its intended home inside the frame (this step helps prevent moisture from getting trapped inside).
- Finally—and this may be most important—make sure that both sides of this piece fit snugly together by checking for gaps at corners or edges before putting on any trim or caulking!
Step 5a: If You’re Replacing Just a Small Section of the Window Pane
If you’re replacing just a small section of the glass pane, you can use a putty knife to remove the old piece of glass. Use a sharp chisel or glass cutter to cut out the new piece of glass, then use a hammer to tap it into place. If your window is large and you don’t have help, consider leaving the old pane in place while installing the new pane.
Step 6A: Reinsert Window Sash
To reinsert the window sash, you will need to:
- Insert pane of glass into frame.
- Insert sash into frame.
- Secure sash with screws.
- Install putty on any exposed gaps in the frame or where you have made any cuts for new panes of glass to be inserted (see “Putting Putty” below).
Never replace a pane of glass with anything less than tempered glass.
When you’re replacing a pane of glass in your window, you have to be sure that you use tempered glass. There are a few reasons for this, and they all come down to safety.
Tempered glass is stronger than regular sheet glass. It can withstand more impact from outside forces, like rocks or even baseballs! But it also has another benefit: It won’t break into sharp shards when it breaks. Instead, tempered glass breaks into large chunks that are less likely to cause injury or damage around them if they fall from the window opening onto something below (like your head).
Tempered is better because it’s stronger and safer than regular window panes—and because there are other types of windows out there besides standard double-hung windows with two sashes that slide up and down vertically through their frames (the kind we’ll be replacing today). In fact, most modern homes have windows made with multiple panes stacked one on top of another vertically instead of horizontally across a frame like those old-fashioned ones we see in movies set in 1920s New York City apartments where everyone smokes cigarettes constantly while drinking coffee by candlelight on dark winter nights.”
Conclusion
If you want to get the job done right, then it’s important to follow these steps. If you’re just getting started with this project, we recommend starting with removing the putty from around your window pane. Once that’s done, remove any molding around it as well before prying off the sash from each side of the frame so that when replacing glass later on there won’t be anything blocking access to those areas (such as in front where the sash meets up with wall). Now go ahead and clean up edges of new glass along both sides of frame so they’re ready for installation before removing old pane completely inside out until completely gone finish cleaning area thoroughly removing all debris dust particles etc.; now install new one carefully aligning corners evenly pushing firmly down middle first then sides towards each other lastly pushing gently upwards until seated properly tightly screwed back down securely finished!
