 1. Gather Your Materials

Before you start, ensure you have all the necessary materials and tools. Here’s what you’ll need:

  • Replacement glass
  • Glazing points
  • Glazing putty
  • Glass cutter
  • Putty knife
  • Tape measure
  • Safety gloves and goggles
  • Utility knife
  • Painter’s tape
  • Chisel

Having everything on hand before you begin will make the process smoother and more efficient.


2. Ensure Safety First

Safety is paramount when dealing with broken glass. Wear safety gloves and goggles to protect yourself from sharp edges. Clear the area of any debris and ensure children and pets are kept away from the workspace.


3. Remove the Broken Glass

Carefully remove the broken glass pieces. Use a utility knife to cut through any remaining putty or sealant holding the glass in place. If the glass is shattered, gently lift the pieces out, starting from the top. Dispose of the glass safely.


4. Clean the Frame

With the old glass removed, it’s time to clean the window frame. Use a putty knife and chisel to remove any old putty and glazing points. Ensure the frame is smooth and free of debris. This step is crucial for ensuring the new glass fits securely.


 5. Measure and Cut the Replacement Glass

Measure the opening of the window frame accurately. Add a small allowance (about 1/8 inch) to ensure the glass fits comfortably without being too tight. Transfer these measurements to your replacement glass and use a glass cutter to cut it to size.


 6. Apply Glazing Putty

Roll glazing putty into thin ropes and press it into the window frame where the new glass will sit. This putty acts as a cushion and sealant for the glass. Make sure the putty is evenly distributed for a secure fit.


 7. Install the New Glass

Carefully place the cut glass into the frame, pressing it gently into the putty. Secure it with glazing points by pushing them into the frame along the edges of the glass. The points will hold the glass in place while the putty sets.


 8. Apply Additional Putty

Once the glass is secured, apply another layer of glazing putty around the edges. Smooth it out with a putty knife, ensuring it forms a neat and sealed edge. This step not only secures the glass but also provides an aesthetic finish.


9. Let the Putty Dry

Allow the glazing putty to dry completely. That may take several days, depending on the product used. Once dry, the putty will harden and firmly hold the glass.


10. Clean the Glass

After the putty has dried, clean the glass thoroughly to remove any fingerprints, smudges, or excess putty. Use a glass cleaner and a soft cloth for a streak-free finish, making your windows look bright and appealing.
