How to Replace an Andersen Casement Window Sash: A Step-by-Step Guide

Andersen casement windows are known for their durability, energy efficiency, and timeless design. However, over time, the window sash may need to be replaced due to wear and tear, damage, or simply to update the look of your home. In this comprehensive guide, we will walk you through the process of replacing an Andersen casement window sash, ensuring a smooth and efficient project.

Gather Your Tools and Materials

Before you begin, it's essential to gather all the necessary tools and materials for the job. Here's what you'll need:

Replacement Andersen casement window sash

Screwdriver (both flathead and Phillips)

Utility knife

Pry bar

Hammer

Putty knife

Tape measure

Level

Safety glasses

Work gloves

Ladder (if working on a high window)

Step 1: Remove the Old Sash

Start by unlocking and fully opening the casement window. This will give you easy access to the sash and its components. Locate the hinge clips on the bottom and top of the window sash. Using your flathead screwdriver, disengage the hinge clips by prying them away from the sash.

Next, carefully lift the sash off the hinge arms. This may require the assistance of another person, especially for larger or heavier windows. Once the sash is removed, set it aside in a safe location.

Step 2: Remove the Old Hardware

With the sash removed, you can now access the hardware attached to it. Using your Phillips screwdriver, remove the screws holding the operator arm and the hinge arms in place. Keep the screws and hardware in a safe place, as you'll need them to install the new sash.

Step 3: Prepare the New Sash

Unpack your new Andersen casement window sash and inspect it for any damage or defects. Place the sash on a clean, flat surface with the exterior side facing down. Using your tape measure and level, ensure that the sash is square and true.

Step 4: Attach the Hardware to the New Sash

Now it's time to attach the hardware to your new sash. Start by attaching the operator arm to the bottom corner of the sash using the screws you removed earlier. Make sure the arm is properly aligned with the sash before tightening the screws.

Next, attach the hinge arms to the top and bottom of the sash using the remaining screws. Double-check that the hinge arms are properly aligned and securely fastened.

Step 5: Install the New Sash

With the hardware attached, you're ready to install the new sash. Carefully lift the sash and place it onto the hinge arms, making sure the arms are fully engaged with the sash. This may be a two-person job, especially for larger or heavier windows.

Once the sash is in place, re-engage the hinge clips by pressing them back into position with your flathead screwdriver. This will lock the sash onto the hinge arms, ensuring a secure fit.

Step 6: Test the Window Operation

Before wrapping up the project, it's essential to test the window's operation to ensure everything is working correctly. Close and lock the window, checking for any gaps or misalignments. Then, unlock and open the window, ensuring it operates smoothly and without any obstructions.

If you encounter any issues, double-check the hardware installation and make any necessary adjustments.

Step 7: Clean Up

With your new Andersen casement window sash installed and operating correctly, it's time to clean up your work area. Dispose of the old sash and any debris from the project, and store your tools and materials.

You've now successfully replaced an Andersen casement window sash, enhancing the look and functionality of your home. By following this step-by-step guide, you can confidently tackle future window sash replacement projects with ease.

INSPIRATION & SOLUTION

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.

Simulated Hung Window with Tilt & Turn Openings

The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.

Why choose the tilt and turn opening method?

Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.

Large Energy Efficient Fixed Windows

Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.

Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.

Every window’s placement and shape not only add to the uniqueness of this home but also provide a more energy-saving ability for the owners.

Doorwin energy-efficient integrated glazing units feature double-pane glass, warm-edge spacers, argon gas fill, Low-E coatings, and fully tempered glass, they can not only create a comfortable and natural indoor environment but also save electricity bills and heating bills of more than 100 USD for the owner, it’s a real bargain compared to choosing a regular glazing set.

Multi-point lock systems provide not only the burglar-resistance but also a tighter compression seam, making the window keeps good energy-efficient performance. Together with Technoform Bautec’s insulation edge bond and sealant strips, these make up our products' top insulation and energy-saving performance.
