Casement windows are arguably the best selling style of windows on the Canadian market. They are also the most energy efficient and practical to use. But, on the other hand, casement windows can be the most expensive of all the types available. And while you may or may not need the benefits of additional energy efficiency in your home, it is definitely worth knowing why casement windows cost more, and what goes into that price.

Casement Window Price: Why Is It More Expensive Compared to Slider?

There are several factors that make casement windows a superior choice to other options, and naturally they are all geared toward homeowner comfort and convenience.

Exceptional energy efficiency. Their design allows for a tighter seal when closed, significantly reducing air leakage and energy costs.
Enhanced security. A unique locking mechanism embedded into the frame makes them more challenging to break into than slider windows.
Ease of operation and maintenance. Casement windows open outward fully, allowing maximum ventilation and easy cleaning from the inside. This feature is particularly useful in hard-to-reach areas.
Optimal aesthetics. Their sleek and versatile design complements various architectural styles, adding value to any property. These windows allow for unobstructed views and ample natural light, creating a more inviting and spacious environment.

As we delve into specific benefits in the following sections, it becomes clear that the initial higher investment in casement windows pays off in the long run through energy savings, security, ease of use, and aesthetic enhancement. Each aspect contributes to a more comfortable, secure, and enjoyable living space, justifying the price difference compared to slider windows.

The Average Cost of Casement Windows

Casement windows are popular among Canadian homeowners due to their versatility and functionality. However, the casement window replacement cost can vary widely based on several factors.

Understanding these factors is crucial to budget effectively for their window installation or replacement.

Size: Larger windows require more materials and labour, increasing the overall cost. Hence, remember that casement window sizes and prices are closely connected, meaning that if you decide to enlarge your current openings, expect a higher price tag.
Custom Features: Unique designs, shapes, or finishes add to the cost due to additional craftsmanship.
Location in the House: Replacements in different home areas, higher stories or basements also impact the final quote.
Glazing: Triple casement window prices are approximately 15% more expensive than double-pane due to better insulation and a more complex manufacturing process.
Colour: Non-standard colours may incur extra costs due to special manufacturing processes.

These factors collectively contribute to the final price of casement windows. Homeowners need to consider these aspects when planning their window installation projects. The table below provides approximate price ranges relevant as of 2025. You can also use our casement window replacement calculator to estimate your specific project.

Casement Window Cost: Compression Seals

A big reason casement windows are the most efficient operable windows is the compression seal technology. The seal, attached around the edges of the moving sash, ensures that the unit is airtight when closed, and doesn’t leak air out or allow drafts in.

Compression seals are far superior to weather stripping used in lower quality windows. There are still companies that manufacture these windows with weather stripping around the edge, so be sure to ask about the seals if you are interested in this style of window.

The hardware utilised in casements is more sophisticated than in other windows. It also works to maximise the efficiency of the window’s compression seals. Multi-point locks physically lock your windows in multiple places. This not only ensures the compression seal is evenly pressed up against the frame of the window for maximum efficiency, but also acts a strong deterrent against break-ins.

Casements also feature a crank mechanism for seamless opening and closing. Unlike with sliders, you don’t have to move the sash by hand, and operating windows is easy with just one hand. Additionally, premium hardware offers a refined finish, complementing the window’s design and adding a touch of elegance to the overall look of the home.

How Enhanced Window Profiles Add to Vinyl Casement Windows Prices

Another important factor in the final cost of casement windows is the window profile. Casement windows are of a higher profile (wider frame) than sliders. This obviously means they require more vinyl to be manufactured and, therefore, cost more. This is especially true for bigger casements, although the time and process are the same as in smaller windows, the amount of material is what drives the casement windows price up. For combination windows, casements can be matched with fixed windows of the same profile to complete the look.

As you can see casements start several hundred dollars higher in price than slider style windows because of their superior energy efficiency and premium hardware.

While the numbers presented here are just ball-park figures, the best way to find out the exact cost is to have someone look not only at your existing windows, but also at the surrounding structure. This may seem like a gimmicky request for a sales pitch, but when it comes to windows there is really no way to price the project over the phone or e-mail.

Good window installers usually need to see exactly the condition of your home and windows in order to know how much work will be required. This also largely determines the final price of your new casement windows.

F.A.Q

Are casement windows more expensive than sliders?

Casement windows are generally more expensive than sliders due to their complex mechanisms and better energy efficiency.

Casement vs single hung cost – what’s cheaper?

Due to their simpler design, operation and size, single-hung windows are typically cheaper than casement windows.

Awning vs casement window cost – what’s the difference?

The cost difference between awning and casement windows is minimal because both styles belong to a crank window group, with variations mainly due to size and hardware differences.
