Step 1: Preparation

Preparation is key to any successful project. Before you begin, ensure you have the necessary materials and safety equipment. This includes:

Safety Gear: Heavy-duty work gloves and safety goggles are essential to protect yourself from sharp glass shards. Consider wearing a long-sleeved shirt for added protection.

Tools:

- Rubber mallet - Putty knife, utility blade, or utility knife - 501 tool, metal scraper, or flathead screwdriver - Measuring tape - Hammer - Chisel - Pliers - Caulking gun - Glass cutter

Materials:

- Replacement glass (cut to size) - Rubber gaskets or seals - Glazing putty or silicone sealant - Glazing points (if applicable) - Fine-grit sandpaper - Linseed oil or wood sealer - Double-sided tape - Clear silicone - Paint (optional, for finishing touches)

Work Area: Clear the area around the window, removing any curtains, blinds, or furniture. Lay a sheet of plastic or cloth over your floors for protection. Ensure the windows are opened fully for proper ventilation.

Remember, safety should always be your top priority. A safe DIYer is a happy DIYer!

Step 2: Removing the Old Glass

If your window is broken, carefully remove any remaining shards from the frame. If you're replacing intact glass, remove the aluminum window frame.

1. Remove the Window Frame: Locate and remove all screws holding the frame in place, then carefully lift it out. Lay the frame on a flat surface.

2. Cutting the Glass: Using a thin putty knife, utility blade, or utility knife, carefully cut along all four sides of the glass. Be cautious not to crack the glass during this process. Once the seal is cut, move to the outside of the window to gently pop the glass tops off.

3. Removing the Glazing Bead or Glass Stops: Employ a 501 tool, metal scraper, or flathead screwdriver to carefully detach all four stops. It's essential to remember to remove the top stop last to prevent the glass from falling out. If necessary, use a suction cup or hold the glass by hand while gently prying it out of the frame.

4. Loosening the Frame: Using a rubber mallet, gently tap the frame to loosen it from the glass, taking care not to damage the glass further. Once loosened, carefully remove the frame from the glass.

5. Removing Broken Glass: After you've prepared your work area, it is important to remove the broken glass carefully. Make sure that you have your safety gear on. Remove the old glass from the window while it is still installed. If the glass doesn't come out easily, apply duct tape to the glass in an 'X' shape. This will help catch any loose shards. Then, use your heat gun, chisel, or a scraper to remove the window glazing compound and points, and pull the glass out in one piece.

Step 3: Measuring the Glass

Measure the thickness, length, and height of the old glass accurately. These measurements are crucial for ordering the correct size replacement glass. If the glass is broken, you can use the broken pieces to determine the dimensions. Be sure to remove all glass fragments from the frame to avoid damaging the new glass during installation.

Step 4: Preparing for Installation

1. Inspect and Clean: Inspect the rubber gaskets or seals around the edges of the old glass. Remove and clean them thoroughly to ensure a proper seal with the new glass. Cleaning the rubber helps prevent any debris from interfering with the installation process. Carefully remove the rubber gasket as you are going to reuse it.

2. Frame Cleaning: With the old sealing or tape removed, the frame should be cleaned thoroughly. A 501 tool, chisel, or flathead screwdriver can be used for this purpose.

3. Applying New Sealant: After cleaning, apply new double-sided tape or clear silicone to the frame. Peel the corners of the double-sided tape and fold them inwards for easy removal after the glass is set. Alternatively, apply clear silicone directly to the frame if you don't have double-sided tape.

4. Prepare the work area: Preparing your work area before you take any other steps when replacing window glass is crucial to ensure a smooth and safe process. Firstly, remove any curtains, blinds, or furniture near the window and clear the space. Then lay a sheet of plastic or cloth over your floors for protection. Make sure the windows are opened fully for proper ventilation. After you've taken all these steps, only then proceed to gather your tools and materials and move forward with the replacement process.

Step 5: Installing the New Glass

1. Positioning the Glass: Lay the new glass flat, ensuring that two edges overhang the surface. Place the rubber seals on these overhanging edges.

2. Inserting the Glass: Carefully insert the glass into the aluminum frame, starting with one-half of the frame. Use a rubber mallet to gently tap the frame into place, ensuring a snug fit. Repeat this process for the other half of the frame.

3. Setting Blocks: Place the bottom of the new glass on setting blocks and centre it in the frame.

4. Securing the Glass: If working alone, consider using a top piece of stop to hold the glass in place. On the inside, peel the tape or have someone assist you while setting the glass in place. Gently push on the glass to ensure a proper seal to the frame.

5. Rubber Gasket: Then put the rubber gasket all around the replacement pane of glass so that it runs along the outside of all of the edges. In the frame where the previous old broken pane of glass was located, put the replacement pane of glass. After tightening all of the screws to hold the glass in place, reassemble the frame in the reverse sequence from how you disassembled it. There is no need for silicone or any other sealant due to the rubber gasket.

Step 6: Reassembling the Frame

1. Tightening Screws: Once the glass is securely in place, reassemble the aluminum frame by tightening the screws removed earlier. Ensure each screw is tightened securely to prevent any gaps or instability in the frame.

2. Reinstalling Glass Stops: Reinstall the glass stops by pushing and snapping them into place. If needed, use a wood block or plastic material to tap them in without scratching the glass. Repeat this process for all four sides. Once the stops are securely in place, clean the glass, and your window replacement job is complete.

3. Final Assembly: Finally, replace the entire window assembly with your window frame on the wall. Put all of the screws back into their same holes to make sure that the fit is secure and perfect.

Step 7: Finishing Touches

1. Cleaning: Clean the glass with a glass cleaner to remove any smudges or fingerprints.

2. Sealing: Apply a bead of silicone sealant around the edges of the glass where it meets the frame for a waterproof finish.

3. Painting (Optional): If desired, paint the frame to match your home's décor.

4. Regular maintenance can extend the life of your aluminum windows.

Conclusion

Replacing a broken window glass in an aluminum frame is a rewarding DIY project that saves time and money while enhancing your home's appearance and functionality. By following these steps and exercising caution throughout the process, you've not only saved money but also gained a valuable DIY skill. Enjoy your newly replaced window glass and the improved appearance and functionality it brings to your home.
