Casement Windows in Toronto
Airtight, crank-open casement windows built for Toronto homes and weather. Unobstructed views, ENERGY STAR vinyl and a lifetime transferable warranty — supplied and installed by our own local crews, from century homes downtown to the suburbs.
Built for Toronto Homes
Why Casement Windows Suit Toronto’s Housing Stock
Toronto’s housing is a patchwork of eras, and the crank-open casement fits almost all of it. The century homes and Victorians of The Annex, Riverdale, Leslieville and Cabbagetown often had wood casements from the start — so a modern vinyl casement keeps the authentic look while finally sealing tight and cranking open with one hand.
In the wartime bungalows and back-splits of Scarborough and Etobicoke, casements are perfect above kitchen counters and in bedrooms where an easy crank beats fighting a painted-shut sash. Midtown semis and infill homes love the clean, modern sightline, and downtown condos and lofts use casements to catch side breezes many floors up.
Because so many Toronto openings are old and out-of-square, we custom-build every casement to your exact opening — no big-box spacers or fillers. And in a heritage conservation district, we help you choose profiles and colours that keep the streetscape intact.
At WindowFixers.ca we both supply and install every casement with our own trained crews, from the free in-home measurement to the final cleanup — across Toronto and the wider GTA.
Why Homeowners Choose Casements
The Advantages of Casement Windows
More airflow, a tighter seal and a cleaner view than almost any other operating window — here is what makes the casement a Toronto favourite.
Easy Crank Operation
A simple fold-down crank swings the sash fully open with one hand — no wrestling with a painted-shut or seized sash. Perfect for hard-to-reach spots above a Toronto kitchen sink or counter.
Airtight Compression Seal
Casements close like a door against a continuous weatherstrip, compressing tight all around. It is the most airtight operating window you can buy — ideal for Toronto’s cold winters and windy lakefront weather.
Unobstructed Views & Light
With no middle rail dividing the glass, a casement is nearly all view. You get maximum daylight and a clean sightline of the yard, street or downtown skyline.
Full-Opening Ventilation
The sash opens 90 degrees to catch side breezes and scoop fresh air into the room — far more airflow than a slider or hung window of the same size.
Egress-Capable Sizing
Because the whole sash opens, a correctly sized casement can serve as a code-compliant egress exit — a smart choice for finished basements and bedrooms in older Toronto homes.
Low-Maintenance Vinyl
Moisture-proof vinyl (uPVC) frames never rot, rust, swell or need repainting — unlike the old wood casements found in so many century Toronto houses.
Configurations
Casement Window Styles We Install
From a single crank-out sash to a wide French pair or a picture-and-casement combination, we build the configuration that fits your opening and how you want the room to feel. Want the full technical rundown on the casement style itself?
See our casement windows guide
Single Casement
One crank-out sash in a single frame — the classic casement. Great on its own for bathrooms, stairwells and narrow walls, or ganged in a row across a wider opening.
Double / French Casement
Two sashes that crank open from the centre with no post between them. When both are open you get an unobstructed, doorway-wide opening and the fullest possible airflow.
Casement Picture Combination
A large fixed picture pane flanked by operating casements — the best of both worlds: a big, clear view in the centre with venting sashes on either side.
Fixed Casement-Style
A non-operating unit built to match the sightlines of your operating casements, so a whole wall of windows looks seamless while keeping cost down where venting is not needed.
Energy Efficiency for Toronto’s Climate
Toronto swings from humid, lake-effect summers to deep winter cold, so the seal on your windows matters. A casement’s compression seal closes the sash tight against the frame on all four sides — the harder the winter wind presses, the tighter it gets. That is why casements are consistently among the most energy-efficient operating windows.
We pair that tight seal with double- or triple-pane Low-E glass and argon fill, insulated multi-chamber vinyl frames, and warm-edge spacers to cut heat loss and stop the interior condensation that plagues older windows.
Every casement we install is ENERGY STAR certified for the Ontario climate zone, so you get lower heating and cooling bills and a more comfortable, draft-free home year-round.
Compare the Styles
Casement vs Other Window Styles
Not sure a casement is right for every opening? Here is how it stacks up against the other styles we install — and where each one shines.
Casement vs Awning
Both crank outward and seal tight. Casements hinge on the side and open taller; awnings hinge at the top and can stay open in light rain — a common pick for wider, shorter openings.
Explore awning windowsCasement vs Slider
Sliders glide sideways and never project outward, so they suit walkways and decks. Casements seal far tighter and open fully, but need clear swing space outside.
Explore slider windowsCasement vs Hung
Single- and double-hung windows slide vertically and match traditional Toronto facades. Casements are more airtight and energy-efficient, with a cleaner, more modern sightline.
Explore hung windowsCasements, Egress & Toronto Permits
Because the whole sash swings open, a properly sized casement makes an excellent egress window — the emergency exit the Ontario Building Code requires for any legal basement or ground-floor bedroom. If you are finishing a basement in an older Toronto home, we confirm the clear-opening size that qualifies.
A straight like-for-like window replacement usually does not need a City of Toronto building permit, but enlarging an opening, cutting a new egress or work in a heritage district can. We tell you plainly what your project needs and handle the details correctly — no guesswork, no surprises.
What to Expect
Our Casement Installation Process
A clear, four-step process so you always know exactly what happens next — from your first measurement to the final walk-through.
Free In-Home Measurement
We measure every opening precisely — including the odd, out-of-square frames common in older Toronto homes — review your glass, colour and hardware options, and give you an upfront, all-in written price.
Careful Removal
We remove your old wood, aluminum or vinyl casements one opening at a time, protecting your floors and heritage trim, and prepare a solid, square opening for the new unit.
Airtight Install & Seal
Your new vinyl casement is set level, fully insulated and sealed inside and out against Toronto’s wind and driving rain — so the crank turns smoothly and the seal stays tight for years.
Finish, Cleanup & Warranty
We finish the trim, haul away every old window and all debris, and back the job with the manufacturer warranty plus our own installation workmanship guarantee.
