Gather the Tools and Materials You Will Need

Before you begin replacing the glass in your aluminium door, it’s important to gather all the necessary tools and materials. This will not only make the process smoother but also ensure that you have everything on hand when you need it.

First off, you’ll need safety gear such as gloves and protective eyewear to prevent any potential accidents or injuries. Next, grab a few basic tools like a screwdriver, pliers, putty knife and utility knife. These will come in handy when removing old glass from the door frame.

Now onto the materials – obviously, you’ll need new pieces of glass cut to size according to your door measurements. You can easily purchase this from a hardware store or online retailer that specializes in glass products. Additionally, get some glazing compound or silicone caulking for securing the new piece of glass into place.

Keep a vacuum cleaner nearby for cleaning up any broken shards of glass during the replacement process. Once you have all these items ready, let’s move onto removing the old glass!

Remove the Old Glass from the Door

Removing the old glass from an aluminium door can be a daunting task, but with the right tools and techniques, you can do it quickly and easily. The first step is to gather all of the materials that you will need for this project.

Start by putting on some protective gloves and eyewear to avoid any injury during the process. Then, remove any screws or bolts holding the frame in place using a screwdriver or pliers. Carefully lift out the glass panel from its frame.

If you’re dealing with cracked or broken glass, handle it carefully to avoid getting cut or injured. Wear thick gloves if necessary when removing shards of broken glass. Once all pieces are removed safely, clean up thoroughly.

Next, use a putty knife to loosen any remaining sealant around the edges of your aluminium frame where your previous window was installed, taking care not to damage your wall or door’s surface in doing so.

Once everything has been cleaned up and cleared away properly – dispose of hazardous waste appropriately – inspect for any damages incurred while removing old glass before beginning installation of new panels!

Cut the New Glass to Size

Cutting the new glass to size for your aluminum door can seem like a daunting task, but with the right tools and technique, it’s actually quite simple. Before you begin cutting, make sure that you measure the opening in your door accurately to ensure that your replacement glass will fit properly.

To cut the glass, use a sharp cutter or scoring tool designed specifically for cutting glass. Make sure to wear gloves and eye protection while handling the glass to prevent injury.

Begin by marking out where you need to cut on both sides of the glass using a straight edge as a guide. Then score along each line using firm pressure and long strokes with your cutter or scoring tool.

Once scored along both lines, carefully break off any excess sections of glass at each end until you have achieved your desired size. It is important not to apply too much force when breaking off pieces as this may cause cracks in the remaining sections.

After completing all cuts needed for perfect sizing, inspect each side of the newly cut piece thoroughly before installation into place.

Install the New Glass in the Door

Now that you have cut the new glass to size, it’s time to install it in your aluminium door. This step needs to be done with caution and care as a slight mistake can lead to unwanted accidents or damage.

Firstly, ensure that the new glass fits perfectly into the frame of the door. Place it gently and make sure there is no gap between the edges of the glass and frame, if there is then use a rubber mallet or some other soft tool to push it in place.

Next, apply an adhesive sealant around all four sides of the new glass. The sealant should be applied evenly along each edge without leaving any gaps or bubbles.

Once you’ve applied sealant on all four sides, press firmly on each side for 30 seconds ensuring that every corner has been pressed down properly. You may also want to clean off any excess sealant with a damp cloth before allowing it dry for at least 24 hours.

After letting everything settle down completely check for air leaks by running your hand along each side of where you installed the new glass. If there are any gaps or leaks found then just reapply more sealant until everything is perfect!

By following these simple steps carefully and patiently, you will successfully replace your old broken window with a brand-new one like a pro!


Replacing a glass in an aluminium door might seem like an intimidating task, but with the right tools and steps, it can be done easily. Remember to prioritize safety by wearing gloves and protective eyewear.

Start by removing the old glass from the door using a putty knife or glazier’s points. Next, accurately measure the dimensions of your new piece of glass and cut it to size with a glass cutter.

Installing the new glass into your aluminium door will require patience and precision. Apply some glazing compound onto the frame before carefully placing in the new pane of glass. Press gently around all edges while adding more glazing compound if necessary.

Let everything dry completely before cleaning up any excess sealant or debris.

By following these simple steps outlined above, you should now have successfully replaced your broken or damaged aluminium door window without needing professional help!
