Casement windows are hinged on one side and open outward using a crank handle. This design allows the window to open fully, providing excellent airflow and wide, unobstructed views.
One of the key advantages of casement windows is their compression seal design. When closed, the sash is pulled tightly against the frame, helping block drafts, moisture, and outside noise. This makes casement windows especially effective in climates with cold winters, wind, and frequent temperature changes.
Casement windows remain a popular choice for homeowners in Southern Ontario, who value comfort, efficiency, and low-maintenance performance over time. They’re especially well-suited if:
Because the window opens fully, casement windows catch even a refreshing breeze more effectively than sliding or fixed windows.
Casement windows typically open to 90°, allowing you to clean the exterior glass from inside your home safely.
Their side-hinged design makes vinyl casement windows easy to operate in tight spaces such as above sinks, counters, or furniture.
The cost of casement windows depends on window size, glass configuration, hardware selection, and installation type. Below is a general price range to help you understand how costs are typically structured. Final pricing is always confirmed during a free in-home consultation.
| Window Size / Style | Price Range (Installed) | Typical Use |
|---|---|---|
| Small Casement (standard) | $400-900 | Basements, small rooms |
| Mid-Size Vinyl Casement | $700-1200 | Bedrooms, kitchens |
| Large / Premium | $1200-1800+ | Living rooms, custom openings |
| Custom / High-End Materials | $1500-2200 | Specialty sizes, wood or fiberglass |
Pricing varies based on window size, glass configuration, installation method (retrofit or full-frame), and structural conditions. Larger or triple-pane units may require reinforced hardware or heavy-duty operators.
Upgrades such as custom colours, laminated or tempered glass, interior trim selections, and brickmould profiles can also influence the overall project cost.

At Total Home Windows and Doors, our casement windows are built using TotalSeal™ Technology, an advanced window system designed for strength, insulation, and long-term performance in Canadian conditions.
Fusion-welded corners form a single solid joint, creating a rigid, leak-resistant frame that helps prevent air and water infiltration over time. A multi-chamber vinyl frame increases structural stability while reducing sound transmission and improving thermal insulation.
Learn how the TotalSeal™ Technology is applied specifically to casement windows, which open outward and place unique demands on the frame and sash. Casement windows require precise geometry and reinforced construction to support side-hinged operation while maintaining a tight seal when closed.
The frame is engineered to remain stable under the loads created by outward-opening sashes, helping prevent twisting, sagging, or long-term misalignment.
The operable sash is reinforced to support the weight of double- or triple-glazed insulating glass units without compromising smooth and easy operation.
Frame geometry is designed to maintain consistent compression of the weather seals around the entire perimeter of the window. This helps ensure uniform sealing pressure,
The frame and sash are engineered to properly support both double- and triple-pane glass configurations while maintaining performance and durability.
The hinge side is reinforced to handle the weight of outward-opening casement windows, helping prevent sagging and ensuring long-term smooth operation.
Encore operators are designed to handle increased sash weight and frequent daily use while protecting internal components from debris.
Casement windows rely on precise locking to maintain even pressure and a consistent seal around the entire frame. The TotalSeal Multi-Point Locking System is engineered to adapt to different window sizes and glass configurations, distributing locking force where it is needed most. This approach improves air and water performance, supports long-term durability, and enhances overall security in side-hinged, outward-opening windows.
As casement windows increase in width – typically around 32-36 inches – achieving even compression along the sash becomes more challenging. The integrated corner drive extends locking force to the upper corner of the window, helping maintain a tighter, more consistent seal across the entire frame. This improves air and water performance, especially on larger casement configurations.
For triple-pane and security glass configurations, where sash weight is significantly higher, the corner drive plays a critical structural role. Supporting the sash at the upper corner helps distribute the load more evenly, reduces stress on hinges and operator mechanisms, and minimizes the risk of sash sagging over time.
The heavy-duty operator is available for wide casement windows, triple-glazed units, and security or laminated glass. It is designed to handle increased sash weight, ensuring smooth operation while reducing long-term stress on hardware components.
Multiple locking points engage the sash along the perimeter, increasing resistance to forced entry and making it more difficult to disengage the window from the frame. At the same time, this distributed locking action helps pull the sash tightly against the frame, supporting consistent sealing and long-term stability.
Revolutionary vinyl windows with sleek aluminum aesthetics. Ultra-slim 2 7/8″ profile, advanced multipoint security, and superior energy efficiency for Canadian homes.
Advanced locking components and hardware systems designed to keep your vinyl casement windows secured, easy to operate, and resistant to air infiltration.
Create windows that fits your home perfectly and reflects its unique style. Choose from an extensive array of design, performance, and finishing options to customize the look, comfort, and functionality of your windows.
Energy efficiency and indoor comfort can be enhanced with Low-E coatings and double- or triple-pane glass configurations. These upgrades help reduce heat loss in winter, limit heat gain in summer, and improve insulation. They also help minimize drafts and outside noise, creating a more comfortable living environment year-round while lowering energy costs.
Safety and security can be enhanced with tempered or laminated glass upgrades. Tempered glass is designed to break into small, blunt pieces, reducing the risk of injury if the glass is damaged. Laminated glass remains in place even when cracked, providing additional protection against impact and forced entry. These options add an extra layer of security while maintaining natural light and overall window performance.
Select from between-the-glass grilles for low maintenance, simulated divided lites (SDL) for a classic look, or TruLite premium divided glass for a true architectural pane appearance.

Windows can be installed using different methods depending on existing conditions and project scope.
Brick-to-brick installation entails the complete removal of old windows and frames, including surrounding brickwork, followed by the installation of new windows in freshly created openings. This method offers greater flexibility in window size and placement, allowing for customized designs to suit specific preferences. However, the process is more labour-intensive and time-consuming, as it involves additional construction work to accommodate the new openings.
Stud-to-stud installation involves removing the existing window, frame, and interior finishes down to the wall studs before installing a new window into the structural opening. It allows installers to properly inspect insulation, moisture protection, and to achieve consistent air sealing around the window. In some cases, it may be performed using a split-frame method, where portions of the existing frame are removed to provide structural access while minimizing interior disruption.
Retrofit installation involves fitting new windows into the existing window frames without altering the surrounding structure. This method is characterized by its simplicity and efficiency, as it avoids the need for extensive structural modifications. Since it utilizes the existing framework, retrofit installation is generally easier to complete compared to brick-to-brick installation. Moreover, it often proves to be more cost-effective due to reduced labour and material requirements.
