DIY Fix: Broken Andersen Window Glass Replacement Secrets!

Replacing Broken Andersen Window Glass: Your DIY Guide

Dealing with broken Andersen window glass can be frustrating, but often you can tackle the replacement yourself. This guide provides the secrets to a successful DIY replacement, focusing on working safely and efficiently.

Assessing the Damage and Determining Your Options

Before diving in, take a moment to thoroughly assess the situation. This will help you determine if a DIY fix is right for you and what materials you’ll need.

Type of Break

Different types of breaks require different approaches.

• Small Crack: A small, non-structural crack might be repairable with specialized resin kits (available at most hardware stores). However, this is usually a temporary fix and aesthetically, the crack may still be visible. Consider replacement if the crack is in the line of sight.
• Larger Crack or Shattered Glass: For safety and long-term integrity, replacement of the glass is necessary.
• Foggy Glass (Seal Failure): This indicates a broken seal in double-pane windows. While you can sometimes replace just the glass unit, it might be more cost-effective to replace the entire window sash, especially with Andersen windows, as they are designed with replaceable parts.

Window Type and Model Number

Identifying your Andersen window type and model number is crucial for ordering the correct replacement glass. Look for a small sticker or etched markings on the window frame, usually near the hinges or latch. Common Andersen window types include:

• Double-hung windows
• Casement windows
• Awning windows
• Gliding windows
• Picture windows

Note the model number and any size information listed. This will be essential when ordering your replacement glass.

Gathering the Necessary Tools and Materials

Having the right tools on hand will make the job much smoother and safer.

Essential Tools

• Safety Glasses: Always wear safety glasses to protect your eyes from glass shards.
• Work Gloves: Protect your hands from cuts. Heavy-duty work gloves are recommended.
• Putty Knife or Scraper: For removing old glazing or sealant.
• Heat Gun (Optional): Can soften old, hardened glazing. Use with caution.
• Measuring Tape: To accurately measure the glass size if you can’t find the model number.
• Pry Bar (Small): Carefully remove trim or stops.
• Glazing Points Tool (If Applicable): For installing glazing points (used in older windows).
• Caulk Gun: For applying sealant.
• Utility Knife: To trim excess sealant.
• Hammer: Use with care when re-installing stops.
• Screwdrivers (Various Sizes): For removing and installing hardware.
• Shop Vacuum: To clean up glass shards.
• Drop Cloth: To protect the surrounding area.

Materials

• Replacement Glass: Order the correct size and type of glass for your Andersen window. Tempered glass is recommended for safety.
• Glazing Putty or Sealant: Choose a sealant compatible with Andersen windows. Check the manufacturer’s recommendations.
• Glazing Points (If Applicable): For older windows.
• Wood Stops (If Needed): To replace any damaged or broken stops.
• Painter’s Tape: To create clean lines when applying sealant.
• Cleaning Supplies: Glass cleaner and rags.

Step-by-Step Replacement Process

The replacement process will vary slightly depending on your specific Andersen window model. However, the general steps are outlined below.

Safety First!

• Wear safety glasses and gloves throughout the entire process.
• Work in a well-lit area.
• If working on an upper-story window, ensure you have a stable and safe working platform.

Removing the Old Glass

1. Remove the Sash (If Possible): Many Andersen window sashes can be easily removed from the frame. This makes the repair much easier and safer. Consult your window’s documentation.
2. Remove the Stops: Carefully remove the interior stops (the small pieces of wood or vinyl that hold the glass in place). Use a pry bar gently to avoid damaging the stops. For some Andersen models, stops are held in place with screws. Remove the screws and then carefully remove the stops.
3. Remove the Old Glass: Carefully remove any remaining pieces of broken glass. Use gloves and a putty knife to loosen any stuck pieces. Be extremely careful to avoid cutting yourself. Dispose of the broken glass safely.
4. Clean the Frame: Remove any old putty, sealant, or debris from the frame. A heat gun can help soften stubborn putty, but use it with caution to avoid damaging the wood or vinyl.

Installing the New Glass

1. Apply Glazing Putty or Sealant: Apply a thin bead of glazing putty or sealant to the frame where the glass will sit.
2. Position the New Glass: Carefully place the new glass into the frame, centering it properly.
3. Secure the Glass:
   • For windows using glazing points: Gently press the glazing points into the frame, securing the glass.
   • For windows using stops: Reinstall the stops, ensuring they are securely in place. If using nails or screws, avoid over-tightening, which could crack the glass.
4. Apply Outer Sealant: Apply a bead of sealant around the perimeter of the glass, where it meets the frame. Use painter’s tape to create clean, straight lines.
5. Smooth the Sealant: Use a wet finger or a sealant smoothing tool to create a smooth, professional finish.
6. Remove Painter’s Tape: Carefully remove the painter’s tape before the sealant dries completely.

Reinstalling the Sash

1. Clean the Glass: Clean both sides of the glass with glass cleaner.
2. Reinstall the Sash: Carefully reinstall the sash into the window frame.
3. Test the Operation: Ensure the window opens and closes smoothly.

Dealing with Andersen Window Specifics

Andersen windows often use unique glazing systems.

Andersen Glazing Beads

Many Andersen windows, especially newer models, utilize a "glazing bead" system. These are vinyl or composite strips that snap into place to hold the glass.

• Removal: Use a specialized glazing bead removal tool (or a very thin, stiff putty knife) to carefully pry the bead away from the frame. Start at a corner and work your way around. Be careful not to break the bead.
• Installation: After the new glass is in place, carefully snap the glazing bead back into place. Ensure it is fully seated and secure.

Ordering the Correct Glass for Andersen Windows

Because Andersen windows are designed to be easily repaired, often the best approach is to order a replacement glass unit directly from an Andersen dealer using your window’s model and serial number. This ensures a perfect fit and proper insulation.

Troubleshooting Common Problems

• Sealant Not Adhering: Ensure the surfaces are clean and dry before applying sealant. Use a primer if necessary.
• Glass Doesn’t Fit: Double-check your measurements. If the glass is slightly too large, you may need to have it custom cut. If it’s too small, the gap will need to be properly sealed.
• Stops Don’t Fit: Ensure the stops are properly aligned and that you are using the correct type of fasteners. If the stops are damaged, replace them.
