Old Pella casement windows have been a popular choice for homeowners for decades, known for their durability, energy efficiency, and timeless charm. However, as with any window, parts can wear out or break over time. If you're looking to repair or maintain your old Pella casement windows, this comprehensive guide will provide you with all the information you need to identify and replace various components, ensuring your windows continue to function properly for years to come.
Before diving into the different parts, it's essential to understand the basic anatomy of a Pella casement window. Casement windows consist of a single sash that swings open on hinges mounted on the side of the window frame. The main components of a casement window include the frame, sash, hinges, operator, and locking mechanism. Let's take a closer look at each of these parts.
The frame provides the structural support for the window and is composed of the head, sill, and side jambs. The head is the horizontal top part of the frame, while the sill is the horizontal bottom part. The side jambs are the vertical parts that connect the head and sill.
The sash is the part of the window that holds the glass and opens outward. It consists of the stiles (vertical parts) and rails (horizontal parts) that surround the glass. Old Pella casement windows may have wooden, aluminum-clad, or vinyl sashes, depending on the model and age.
The hinges are the pivot points that allow the sash to swing open and closed. Pella casement windows typically use two types of hinges: a top hinge and a bottom hinge. The top hinge features a sliding mechanism that helps control the sash's opening angle, while the bottom hinge is a pivot point that supports the sash's weight.
The operator is the mechanism that allows you to open and close the window. Pella casement windows use a crank-style operator, which consists of a handle, gears, and an arm that connects to the sash. Turning the handle rotates the gears, which in turn moves the arm, causing the sash to open or close.
The locking mechanism secures the window when it's closed, ensuring a tight seal and preventing drafts. Pella casement windows typically use a multi-point locking system, with lock points located along the vertical edge of the sash. The lock handle controls the locking mechanism, engaging or disengaging the lock points as needed.
Now that you have a better understanding of the various components of a Pella casement window, let's discuss how to identify and replace some common parts that may wear out or break over time.
If your window is difficult to open or close, or the handle is stripped or broken, you may need to replace the operator. To do this, follow these steps:
1. Remove the handle by loosening the set screw and pulling it off.
2. Remove the operator cover (if applicable) by prying it off with a flathead screwdriver.
3. Unscrew and remove the operator mounting screws.
4. Carefully pull the operator arm off the sash bracket.
5. Install the new operator by reversing the steps above.
If your window is not opening or closing smoothly, or the sash is sagging, you may need to replace the hinges. To do this, follow these steps:
1. Remove the sash by opening the window and disconnecting the operator arm.
2. Unscrew and remove the hinge screws from the sash and frame.
3. Install the new hinges by reversing the steps above.
If your window is not sealing properly, or the lock handle is broken, you may need to replace the locking mechanism. To do this, follow these steps:
1. Remove the lock handle by loosening the set screw and pulling it off.
2. Unscrew and remove the lock mechanism from the sash.
3. Install the new lock mechanism by reversing the steps above.
Proper maintenance can extend the life of your old Pella casement windows and prevent the need for frequent part replacements. Some tips for maintaining your windows include:
Regularly clean the sash and frame to remove dirt and debris that can hinder window operation.
Lubricate the operator gears, hinges, and locking mechanism with a silicone-based lubricant to ensure smooth operation.
Inspect the weatherstripping for wear or damage and replace as needed to maintain a tight seal and prevent drafts.
Check the sash and frame for signs of rot or damage, and repair or replace as needed to maintain structural integrity.
By following this guide, you can ensure that your old Pella casement windows continue to function properly and maintain their classic charm for years to come. With a little knowledge, some elbow grease, and the right replacement parts, you can breathe new life into your windows and keep them looking and working their best.
Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.

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.
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.
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.
Aluminum Door offered an air of uniqueness and elegance to a home. With their luxurious patterns and beautiful finishes, it provides this house with a bounty of aesthetics and security. Aluminum entry doors allow you to resist any weather extremes, corrosion, and pests.
