Step-by-Step Guide to Replacing Window Glass
Step 1: Safety First
Always prioritize safety. Wear safety glasses and gloves to protect yourself from sharp glass edges and potential injuries during the replacement process.
Step 2: Remove the Broken Glass
Start by carefully removing the broken glass pieces. Use a utility knife to cut away the glazing putty or sealant around the pane. If the glass is shattered, gently tap it with a rubber mallet to break it further, making it easier to remove.
Step 3: Clean the Frame
Once the glass is removed, clean the aluminum frame thoroughly. Use a putty knife to scrape off any remaining sealant or debris. This step is crucial to ensure the new glass pane fits securely.
Step 4: Measure and Order the Replacement Glass
Measure the dimensions of the old glass pane. Be precise with your measurements, as ordering the correct size is essential for a proper fit. Once you have the measurements, order a replacement glass pane from a local glass supplier or hardware store.

Once your replacement glass is ready, it’s time to install it. Follow these steps:
- Apply Glazing Putty: Apply a thin layer of glazing putty or sealant around the inside edge of the frame. This will help secure the new glass pane.
- Position the Glass Pane: Carefully place the new glass pane into the frame. Use a suction cup for larger panes to ensure a secure grip. Ensure the glass is centered and sits evenly within the frame.
- Secure the Glass Pane: If your window requires glazing points, insert them around the edges of the glass to hold it in place. Use a glazing tool or putty knife to press them in gently.
- Apply Additional Glazing Putty: Apply another layer of glazing putty or sealant around the outer edge of the glass pane. Smooth it out with a putty knife for a clean finish.
Step 6: Allow the Putty to Cure
Allow the glazing putty or sealant to cure as per the manufacturer’s instructions. This usually takes about 24-48 hours. Avoid opening or putting pressure on the window during this time to ensure a secure seal.
Final Touches
Once the putty has cured, clean the glass surface with a window cleaner and a soft cloth. Inspect the window to ensure it opens and closes smoothly. Congratulations, you’ve successfully replaced the window glass in your aluminum frame!
