Portage Ave casement window installation — measured, sealed, warrantied

Casement windows crank open on a side hinge and clamp shut against the frame — one of the tightest-sealing, most energy-efficient styles for Portage Ave.

The tightest seal we install

A casement window seals tighter than almost anything else we install, and that is exactly why it suits Portage Ave. When you crank it shut, the sash presses into a compression gasket around the whole frame — like a fridge door — instead of sliding past a brush seal the way a slider does. Under winter wind pressure that seal actually tightens, so you get less air leakage right when you need it most.

That airtightness translates straight into comfort and lower bills on the walls that take the weather: north and west elevations, exposed corners, and the rooms where you feel the draft today.

Casements come in vinyl or fiberglass for maximum efficiency, and they pair well with fixed picture windows for a big view with an opening section for airflow.

Airtight, easy to open

A single crank swings the sash fully open for excellent ventilation and — because it opens wide — lets you reach the outside of the glass from inside for easy cleaning, which matters on a second storey. The multi-point lock pulls the sash evenly into the seal all the way around, not just at one point.

Every casement is measured on site and air-sealed by our own crews with backer rod and low-expansion foam, listed line by line with its glass package and U-factor in the written quote, and backed by a written frame-and-glass warranty.

Casement Window Installation questions answered

Efficiency, wind performance and easy cleaning for casements.

Are casement windows more efficient than sliders?

Generally, yes. A casement seals by compression — the sash is cranked tight into a gasket around the whole frame — while a slider seals against brush weatherstripping that lets a little more air past by design. In a windy Portage Ave winter that difference adds up: casements leak less and hold their efficiency better, especially on exposed walls. Sliders still have their place where you want a wide, low opening or an easy reach over a counter, and we will point you to the right style for each room.

Do casement windows work in high wind?

Yes — and the tighter it blows, the better a casement seals. Wind pressure pushes the sash harder into its compression gasket, so leakage actually drops under load, which is the opposite of how a sliding window behaves. The one thing to plan is swing direction and location, so an open sash is not caught by a gust or blocked by a walkway; we advise on hinge hand and placement at the measure so it opens safely and catches the breeze you want.

Are they easy to clean?

Yes — a casement opens fully on its hinge, so you can reach the entire outside face of the glass from inside the room. That is a real advantage on upper floors and over decks or garden beds where an outside ladder is awkward or unsafe. The crank also lets you set a precise opening for ventilation without swinging it wide, and the hardware is easy to operate for most hands. We can show you the operation at the estimate.

Are casement windows good for egress?

Yes — because a casement swings fully open, it often meets egress clear-opening requirements in a smaller unit, which makes it a common choice for basement bedrooms.

Do casement cranks and hardware wear out?

Quality operators last for years, and if one ever wears we can replace just the crank or gearbox rather than the whole window.

The casements seal up tight as a drum. On a windy night you can feel how much less draft there is compared to our old sliders.

M. Lavallee

Homeowner, Portage Ave

Love that they crank right open for cleaning and lock down airtight when closed. Perfect over the kitchen sink.

J. Krahn

Replaced four old windows with casements and the difference in comfort on the north wall is night and day.

A. Diallo

Smooth cranks, tight seal and a tidy install. They even advised which way each one should swing.
