When a window pane is broken, it can be a major inconvenience. Not only does it let in cold air and drafts, but it can also be a safety hazard. Replacing a window pane is a relatively simple task that can be completed in a few hours. However, there are a few things you should keep in mind before you get started.
First, you need to determine what type of window you have. There are two main types of windows: single-pane and double-pane. Single-pane windows are made of a single sheet of glass, while double-pane windows are made of two sheets of glass with a vacuum or gas between them. Double-pane windows are more energy-efficient than single-pane windows, so if you are replacing a single-pane window, you may want to consider upgrading to a double-pane window instead. Once you have determined the type of window you have, you need to gather the necessary tools and materials. You will need a new window pane, a putty knife, a hammer, and some nails. If you are replacing a double-pane window, you will also need a heat gun or a hair dryer.
Finally, you can begin replacing the window pane. Follow these step-by-step instructions to replace your window pane safely and efficiently. Before you begin, make sure to wear safety glasses and gloves to protect yourself from broken glass. First, use the putty knife to remove the old putty from around the edges of the window pane. Be careful not to damage the wood or the glass. Once the old putty has been removed, you can remove the old window pane. If you are replacing a double-pane window, you will need to use a heat gun or a hair dryer to soften the sealant around the edges of the window pane. Once the sealant has been softened, you can use a putty knife to remove the old window pane.
Applying Glazing Compound
Glazing compound is a pliable material that seals the gap between the glass and the window frame. It helps to keep out moisture and drafts, and it also helps to hold the glass in place. To apply glazing compound, you will need:
- A glazing gun
- A tube of glazing compound
- A putty knife
- A damp cloth
To apply the glazing compound, follow these steps:
1. Load the glazing gun with the tube of glazing compound.
2. Cut the tip of the tube at an angle.
3. Apply a bead of glazing compound around the perimeter of the window frame, where the glass will sit.
4. Use the putty knife to smooth out the glazing compound and to press it into the gap between the glass and the frame.
5. Carefully insert the glass into the window frame, pressing it into the glazing compound. Use a small hammer and a block of wood to tap the glass into place if necessary. Make sure that the glass is evenly bedded in the glazing compound and that there are no gaps.
Finishing Touches
Once your replacement pane is securely in place, it’s time to add the finishing touches. These steps will ensure a professional-looking finish and optimal performance.
8. Caulk Around the Glass
Apply a thin bead of silicone caulk around the perimeter of the glass, where it meets the frame. Use a caulk gun to ensure even application. Smooth the caulk with your finger or a caulking tool to create a neat seal. Allow the caulk to cure according to the manufacturer’s instructions.
Tip: For a color-matched seal, select a caulk that matches the frame color.
Additional Finishing Touches
- Install any trim or molding that was removed.
- Clean the glass and frame with a glass cleaner.
- Test the operability of the window to ensure it opens and closes smoothly.
Tools and Materials
Replacing a window pane can be a relatively straightforward task with the right tools and materials. Here’s what you’ll need:
Tools:
- Putty knife
- Phillips screwdriver or drill
- Hammer or mallet
- Glass cutter
- Glazier’s points
- Caulk gun
Materials:
- New window pane (cut to size)
- Glazing compound
- Nails
- Caulk
Additional Items:
- Safety glasses
- Work gloves
- Wood shims (optional)
Glazier’s Points
Glazier’s points are triangular metal nails that hold the window pane in place. They are about 1 inch long and have a sharp point and a blunt head. To install a glazier’s point, hold it by the head and insert the point into the groove between the window frame and the wood stop. Press the point down and then tap the head with a hammer or mallet to drive it in flush with the wood.

How to Replace a Window Pane
Replacing a window pane is a relatively simple task that can be completed in a few hours. By following these steps, you can save yourself the cost of hiring a contractor.
- Gather your materials. You will need a new window pane, a putty knife, a hammer, and some nails.
- Remove the old window pane. Use the putty knife to carefully pry the old window pane out of the frame. Be careful not to damage the frame.
- Clean the frame. Use a damp cloth to clean the frame of any dirt or debris.
- Apply putty to the frame. Apply a thin layer of putty to the frame around the edges of the opening. This will help to seal the new window pane in place.
- Insert the new window pane. Carefully insert the new window pane into the frame. Make sure that the pane is properly centered and that the edges are flush with the frame.
- Secure the window pane. Use the hammer and nails to secure the window pane in place. Drive the nails into the frame around the edges of the pane.
- Apply additional putty. Apply a thin layer of putty around the edges of the window pane to seal it in place and to prevent drafts.
