Benefits of This Window Style
We often recommend this window style for homeowners who want reliable ventilation and a strong seal.
- Maximum Ventilation & Control: You can open the sash fully to allow fresh air to circulate efficiently.
- Tight Seals for Better Energy Efficiency: Compression sealing helps limit heat loss during harsh winters in Ottawa.
- Easy Operation & Accessibility: Crank systems allow smooth opening without heavy lifting.
- Stylish Contemporary Appearance: Slim frame lines offer a clean look suited to many home styles.
When closed, casement windows press firmly against the frame, helping create a tighter seal than many sliding options.

Your choice of colour
Most homeowners choose stock white for their replacement windows, and it's a great all-around option. But you don't have to: our Vinyl-Pro VY-Series windows come in a full range of durable factory finishes to suit any home style. If none of these fit, custom paint is available too.

What Our Clients Say
FAQs
Learning more about a casement window can help you decide if it’s the right option for your home in Ottawa and your comfort needs.
Here are some of the most common questions we receive.
What is the lifespan of a casement window?
A properly installed casement window typically lasts around 20–30 years, and sometimes longer when quality materials are used. The biggest factors affecting lifespan are the quality of the window, exposure to weather, and the quality of the installation. Many of the early replacements we see are actually due to poor installation rather than to the window itself.
How much does it cost to install a casement window?
The cost of installing a casement window can vary quite a bit depending on the size of the opening, the glass package, and whether any structural adjustments are needed. In many homes we visit, pricing changes once we see the actual window frame and wall condition. That’s why we always measure on-site and provide a detailed estimate after assessing the home.
What is the downside of casement windows?
Casement windows open outward, so they need enough exterior space to swing freely without obstruction. This can sometimes be an issue if there are walkways, railings, or landscaping directly outside the window. Over many years of use, the crank mechanism may also need occasional servicing, which is normal for operable hardware.
Is a casement window more expensive than a regular window?
Casement windows are sometimes slightly more expensive than basic sliding styles because they use more hardware and a compression sealing system. From what we’ve seen on many projects, that design often results in better sealing and airflow control. Many homeowners feel the added performance and ventilation make the difference worthwhile.
