Casement windows are a popular option when you want maximum airflow and an easy-to-use design. The sash opens outward on side hinges, letting you “catch” breezes and direct ventilation into the room.
Omega Universal provides casement window replacement and installation with clean finishing, proper sealing, and smooth operation. To get started, call +1 416 663-7070 or use Request an Estimate on the Contact page.
What is a casement window?
A casement window is a side-hinged window where the sash swings outward rather than sliding up/down or left/right. Many casement windows use a crank-style operator for controlled opening and secure closing.
Best for
- Kitchens and bathrooms where you want quick, strong ventilation.
- Rooms facing prevailing winds (casement can help “scoop” airflow).
- Hard-to-reach locations (for example, above a sink) where a crank handle is convenient.
- Homes that prefer a clean, contemporary look with a wide unobstructed view.
Key benefits of casement windows
- Strong ventilation control: open wider and direct airflow into the room.
- Tight closure: the sash compresses against weatherstripping when closed, helping reduce drafts.
- Clear views: typically fewer muntins and a wide glass area.
- Easy everyday operation with a simple handle/crank.
Casement vs. double hung (quick note)
Double hung windows slide vertically and offer top/bottom venting options. Casement windows swing outward, which often gives a wider opening and stronger breeze capture.
Common reasons homeowners replace old casement windows
- Drafts, whistling, or cold spots from worn weatherstripping or poor sealing.
- Stiff operation (worn hinges, operator/crank issues, frame shift over time).
- Fogging between panes (insulated glass seal failure).
- Water staining near the sill/trim from older installation details.
Our installation approach
Casement windows perform best when the opening is square, the frame is properly sealed, and hardware is aligned for smooth swing and tight closure. Omega Universal focuses on careful measurement, clean removal, correct insulation/sealing, and tidy finishing details.

Frequently Asked Questions (Casement Windows)
1) How do casement windows open?
They swing outward on side hinges, typically controlled by a handle or crank operator.
2) Are casement windows good for ventilation?
Yes. Because they open outward, they can provide a large opening and help direct airflow into the room.
3) Do casement windows work well over a kitchen sink?
Often yes—because a crank handle can be easier to operate than lifting/sliding, especially when access is limited.
4) Can casement windows leak in rain or wind?
They shouldn’t when properly installed and sealed. Leaks usually come from aging seals/hardware or poor installation details.
5) Why is my casement window hard to open or close?
Common causes include worn operators, loose hinges, or minor frame alignment issues. An on-site assessment can confirm whether repair or replacement makes sense.
6) Are casement windows secure?
When closed and locked properly, they can be very secure because the sash is pulled tightly into the frame.
