How to replace double glazing glass
Double glazing glass is a cost-effective solution for homeowners looking to improve their home’s energy efficiency and reduce outside noise. Over time, however, the glass may become cracked, damaged, or foggy, compromising its ability to provide the desired benefits. Fortunately, replacing double glazing glass is a relatively straightforward process that can be done by most DIY enthusiasts. In this guide, we will walk you through the necessary steps to help you successfully replace double glazing glass.
Step 1: Preparation
Before you begin the replacement process, gather all the tools and materials you will need. This typically includes a utility knife, putty knife, rubber mallet, glazier points, glazing compound, and a caulking gun. It is also important to measure the dimensions of the glass accurately to ensure you purchase the correct size for replacement.
Step 2: Removing the Old Glass
Start by gently removing the glazing beads using a putty knife or screwdriver. Take care not to break or damage the beads, as you will need them later. Once the glazing beads are removed, carefully take out the old glass and clean the window frame of any debris or old caulking to provide a clean surface for the new glass.
Step 3: Installing the New Glass
Apply a thin layer of glazing compound to the window frame and press the new glass firmly into place. Use glazier points to secure the glass by gently tapping them into the frame around the perimeter. Ensure that the glass is level and centered within the frame. Once the glass is securely in place, replace the glazing beads by gently pressing them back onto the window frame.
Following these steps will help you replace double glazing glass and restore your window’s energy efficiency and functionality. Remember to use caution throughout the process and always wear appropriate safety gear. If you feel unsure or encounter any difficulties at any stage, it is recommended to seek professional assistance in order to achieve the best results.

Step 1: Protection
Prior to beginning the glass replacement, ensure you have the proper protection by wearing gloves and goggles. Lay down a dustsheet to catch any glass shards.

Carefully remove any broken glass by gently tapping it with a hammer. Use a chisel to break away any remaining glass, and be sure to remove all glass fragments from the frame.
Step 3: Cleaning the Frame
Thoroughly clean the frame with window cleaner to remove any dirt or debris. This will ensure proper adhesion of the new glazing panel.

Step 6: Inserting the Glazing Panel
Carefully insert the glazing panel into the frame, pressing it firmly against the putty seal. Make sure it fits snugly and is centered within the frame.
Step 7: Securing the Glazing Panel

Assessing the Damage and Gathering Materials
Before you begin replacing the double glazing glass, it’s crucial to assess the extent of the damage. Inspect the glass closely to determine if the crack, chip, or break can be easily repaired or if a full replacement is necessary.
If the damage is small and isolated, you may be able to repair it successfully using the appropriate glass repair kit. However, if the glass is extensively damaged or shattered, it’s generally recommended to replace the entire pane to ensure proper insulation and security.
After assessing the damage, carefully measure the dimensions of the glass pane that needs to be replaced. Make note of the thickness, height, and width of the glass to ensure you purchase the correct replacement. Additionally, check the type of glass used in your double glazing unit, such as safety or tempered glass, and purchase the same type for the replacement.
Once you have all the necessary measurements, gather the materials needed for the replacement. This typically includes safety gloves, a soft cloth or sponge for cleaning, a putty knife or scraper for removing old sealant or putty, glass cleaner, new glass pane, some glazing points or clips, and the appropriate sealant or putty for securing the glass in place.
Materials needed for replacing double glazing glass:
- Safety gloves
- Soft cloth or sponge
- Putty knife or scraper
- Glass cleaner
- New glass pane
- Glazing points or clips
- Appropriate sealant or putty
Note:
Depending on the specific requirements of your double glazing unit, you may need additional materials. Consult the manufacturer’s instructions or seek professional advice if you are uncertain about any aspect of the replacement process.
Removing the Old Glass
Before you can install new double glazing glass, you will need to remove the old glass from the window frame. Follow these steps to safely and effectively remove the old glass:
- Gather the necessary tools: safety gloves, goggles, putty knife, glazing compound or sealant, and a pry bar or hammer.
- Put on the safety gloves and goggles to protect your hands and eyes.
- Start by removing any old glazing compound or sealant from around the edges of the glass. Use the putty knife to carefully scrape away the old compound.
- Once the compound is removed, you can gently tap the glass with a pry bar or hammer to loosen it from the frame.
- Be cautious and apply even pressure while tapping to avoid breaking the glass.
- Once the glass is loose, carefully remove it from the frame and set it aside.
- Inspect the window frame for any remaining bits of glass or debris. Use a vacuum or brush to clean out any remnants.
- If there are any remaining pieces of glazing compound or sealant, use the putty knife to scrape them away.
- Once the frame is clean and free of debris, it is ready for the new double glazing glass to be installed.
Remember to handle the old glass with care to avoid cuts or injuries. Dispose of it properly to prevent accidents. Be mindful of any specific instructions or precautions detailed in the manufacturer’s guide or recommended by a professional.
Preparing the Frame and Installing the New Glass
Before installing the new double glazing glass, it’s important to ensure that the frame is in good condition and properly prepared. Follow these steps:
- Inspect the frame for any damage or rot. If any issues are found, repair or replace the affected areas.
- Clean the frame thoroughly, removing any dust, dirt, or debris.
- Measure the dimension of the frame to determine the size of the replacement glass needed.
- Remove any old putty or sealant around the frame using a scraper or putty knife.
- Carefully place the new double glazing glass into the frame, ensuring it fits securely.
- Apply a thin layer of putty or sealant around the edges of the frame to seal the glass.
- Press the glass firmly into the putty or sealant, making sure it is level and secure.
- Clean up any excess putty or sealant using a clean cloth or sponge.
- Allow the putty or sealant to dry completely before moving or using the window.
By following these steps, you can successfully prepare the frame and install your new double glazing glass. It’s important to take care during the installation process to avoid any damage and ensure a proper fit.
Finishing the Replacement
Once you have successfully removed the old double glazing glass and installed the new one, there are a few final steps to complete the replacement process.
Clean the Glass: Before finishing the replacement, make sure to clean the new glass thoroughly. Use a non-abrasive glass cleaner and a lint-free cloth to remove any dust or fingerprints from the surface.
Apply Sealant: Apply a bead of silicone sealant to seal the edges of the glass. This will provide extra insulation and prevent any drafts or leaks. Use a caulking gun to apply the sealant evenly along the edges of the glass.
Secure the Glass: To ensure that the glass is securely held in place, use glazing points or clips. These small metal pieces can be inserted into the surrounding frame to hold the glass in place. Use a putty knife or a flathead screwdriver to gently press the points or clips into the frame.
Apply Putty: Finally, apply a thin layer of putty to the outside of the glass. This will help to seal any gaps and provide a finished look. Use a putty knife to smooth the putty and create a neat appearance.
Note: It is important to follow the manufacturer’s instructions for applying sealant and putty, as different products may have specific requirements.
