Removing the Sash

The first step in replacing the glass in your Andersen double-hung window involves removing the sash. This process allows for easier access to the old glass and facilitates a seamless transition to the glass removal and replacement stages. Follow these detailed steps to effectively remove the sash from your window:

1. Open the Window: Begin by fully opening the window to its maximum height. This will provide ample space to maneuver and remove the sash without any obstructions.

2. Locate the Sash Locks or Latches: Identify and disengage any sash locks or latches that may be securing the sash in place. Depending on the window model, these locks or latches may be located on the top or bottom rail of the sash.

3. Release the Tilt Latches (if applicable): If your Andersen double-hung window features tilt-in sashes for easy cleaning, locate and release the tilt latches on both sides of the sash. This will allow the sash to tilt inward for removal.

4. Support the Sash: With the window fully open, provide support to the sash as you prepare to remove it. This can be done by firmly grasping the sides of the sash to prevent it from falling or shifting during removal.

5. Lift and Angle the Sash: Carefully lift the sash upward while angling it slightly inward. Be mindful of the sash's weight and ensure a firm grip to prevent any accidental drops or damage.

6. Clear the Sash from the Frame: Once the sash is angled inward, carefully guide it out of the window frame. Take note of any guide pins or tracks that may be present and ensure a smooth, controlled removal.

7. Set Aside the Sash: Place the removed sash in a safe and designated area, ensuring that it is positioned horizontally to prevent any warping or damage.

By following these steps, you can successfully remove the sash from your Andersen double-hung window, setting the stage for the subsequent removal of the old glass and the installation of the new glass. With the sash safely removed, you are now ready to proceed to the next phase of the glass replacement process, where you will effectively remove the old glass and prepare for the installation of the replacement glass.

Removing the Old Glass

With the sash successfully removed, the next crucial step in the glass replacement process for your Andersen double-hung window is the removal of the old glass. This phase requires precision and care to ensure the safe extraction of the existing glass and prepare the window frame for the installation of the replacement glass. Follow these detailed steps to effectively remove the old glass from your window:

1. Protective Measures: Prioritize safety by wearing protective gloves and safety glasses before handling the old glass. This will safeguard your hands and eyes from potential injuries during the removal process.

2. Inspect the Glazing Putty: Examine the perimeter of the window frame to identify the presence of glazing putty securing the old glass. In some cases, the putty may have deteriorated or become brittle, making it easier to remove. However, if the putty is still intact, it will need to be carefully loosened and removed.

3. Loosen the Glazing Putty: Use a heat gun or hair dryer to gently apply heat to the glazing putty surrounding the old glass. The heat will soften the putty, making it more pliable and easier to remove. Take care not to overheat the putty or the surrounding window frame.

4. Careful Removal of Glazing Putty: Once the glazing putty has been sufficiently softened, carefully insert a putty knife between the putty and the window frame. Slowly and methodically work your way around the perimeter of the glass, gently prying and loosening the putty to release the old glass.

5. Lift and Remove the Old Glass: With the glazing putty loosened and removed, carefully lift the old glass from the window frame. Exercise caution to prevent any accidental breakage or injuries during the extraction process.

6. Clean the Window Frame: After removing the old glass, thoroughly clean the window frame to eliminate any residual putty, debris, or adhesive. Use a solution of mild detergent and water, along with a soft cloth or sponge, to ensure that the frame is clean and free from any obstructions.

7. Inspect the Frame and Sash: While the old glass is removed, take the opportunity to inspect the window frame and sash for any signs of damage or wear. Address any issues such as rot, decay, or damage to the frame before proceeding with the installation of the replacement glass.

By meticulously following these steps, you can effectively remove the old glass from your Andersen double-hung window, paving the way for the seamless installation of the replacement glass. With the old glass safely extracted and the window frame meticulously cleaned, you are now prepared to proceed to the next phase of the glass replacement process, where you will install the new glass and reassemble the sash to complete the restoration of your window.

Installing the New Glass

With the old glass successfully removed and the window frame meticulously cleaned, it's time to proceed with the installation of the new glass in your Andersen double-hung window. This phase of the glass replacement process requires precision and attention to detail to ensure a secure and weatherproof fit for the replacement glass. Follow these detailed steps to effectively install the new glass and set the stage for the reassembly of the sash:

1. Measure and Prepare the Replacement Glass: Begin by carefully measuring the dimensions of the window opening to ensure an accurate fit for the replacement glass. If the replacement glass needs to be custom-cut to match the specific dimensions of your window, utilize a glass cutter to achieve precise cuts. Ensure that the replacement glass aligns perfectly with the window frame for a seamless installation.

2. Apply Glazing Compound or Putty: Prior to placing the replacement glass in the window frame, apply a thin bead of high-quality glazing compound or putty along the perimeter of the frame. This will create a secure seal and provide stability for the replacement glass. Ensure that the putty is evenly distributed and covers the entire contact area between the frame and the glass.

3. Carefully Position the Replacement Glass: With the glazing compound or putty in place, gently position the replacement glass into the window frame, ensuring a snug and secure fit. Take care to align the glass properly and apply gentle pressure to seat it firmly within the frame. Verify that the glass sits evenly and securely in the designated space.

4. Secure the Glass with Glazier's Points: To further secure the replacement glass in place, carefully insert glazier's points along the edges of the frame, spacing them evenly to provide consistent support. These small metal clips will help anchor the glass and prevent any shifting or movement once the sash is reassembled.

5. Apply Additional Glazing Compound or Putty: Once the replacement glass is secured with glazier's points, apply an additional layer of glazing compound or putty over the points and along the edges of the glass. This secondary application will reinforce the seal and provide added protection against moisture and air infiltration.

6. Clean Excess Glazing Compound or Putty: After the replacement glass is securely in place, carefully remove any excess glazing compound or putty using a putty knife or a similar tool. Ensure that the edges are clean and smooth, creating a neat and professional finish for the installed glass.

By meticulously following these steps, you can effectively install the new glass in your Andersen double-hung window, setting the stage for the reassembly of the sash and the completion of the glass replacement process. With the replacement glass securely in place and the window frame sealed, you are now ready to proceed to the final phase of reassembling the sash and restoring your window to its optimal condition.

When replacing the glass in an Andersen double-hung window, make sure to wear gloves and eye protection. Use a putty knife to remove the old glazing and carefully insert the new glass, securing it with glazing points before applying new glazing compound.

4. Engage the Tilt Latches (if applicable): If your Andersen double-hung window features tilt-in sashes, engage the tilt latches on both sides of the sash to secure it in the upright position. This step is essential for ensuring the stability and security of the reassembled sash.

5. Test the Sash Operation: Once the sash is reassembled, test its operation by smoothly raising and lowering it within the window frame. Verify that the sash moves freely, locks securely, and maintains proper alignment without any binding or resistance.

6. Check for Proper Sealing: Inspect the perimeter of the sash to ensure that it forms a tight seal with the window frame. This step is crucial for optimizing the energy efficiency and weatherproofing of the reassembled window.

7. Final Adjustments (if necessary): If any adjustments are needed to ensure the proper alignment and operation of the sash, make minor tweaks as required. This may involve fine-tuning the positioning of the sash or addressing any minor issues that affect its functionality.

By meticulously following these steps, you can effectively reassemble the sash of your Andersen double-hung window, completing the glass replacement process with precision and attention to detail.
