How to Re-Glaze a Window

Over time, the glazing on windows can become cracked or damaged, allowing air and water to seep into your home. Re-glazing your windows can help improve their energy efficiency and prevent further damage. Here’s a step-by-step guide on how to re-glaze a window:

1. Remove the Old Glazing

Use a putty knife or glazing tool to remove the old glazing from the window frame. Be careful not to damage the wood or the glass. You may also need to remove any remaining glazing points or metal clips that hold the glass in place.

2. Clean the Window Frame

Use a wire brush or sandpaper to remove any remaining glazing or paint from the window frame. You may also want to clean the frame with soap and water to remove any dirt or debris.

3. Measure the Glass

Measure the size of the glass to ensure that the replacement glass fits properly. You can do this by measuring the height and width of the opening where the glass will be installed.

4. Apply New Glazing

Using a glazing tool, apply a bead of glazing compound to the edge of the window frame where the glass will be installed. Place the replacement glass into the frame and press it firmly into place. You may need to use glazing points or metal clips to hold the glass in place.

5. Apply Additional Glazing

Once the glass is installed, use a glazing tool to apply an additional bead of glazing compound around the edge of the glass. Smooth out the compound with your finger or a putty knife to create a neat, even finish.

6. Let the Glazing Dry

Allow the glazing compound to dry completely before painting or finishing the window frame. This may take several days, depending on the type of glazing compound used.

7. Paint or Stain the Window Frame

Once the glazing compound is dry, you can paint or stain the window frame to match the rest of the window. This will help protect the frame from further damage and improve the overall appearance of the window.

In conclusion, re-glazing a window can be a simple and cost-effective way to improve the energy efficiency of your home and prevent further damage to your windows. By following these steps, you can re-glaze your windows yourself and enjoy the benefits of well-maintained windows. If you’re unsure about doing it yourself, you may want to consult with a professional glazier.
