The casement window is contemporary in design and the most efficient in preventing air infiltration. Casement windows are hinged on the side so they vent vertically. The superior glass area of the casement window lets you enjoy the view without compromising on durability or performance. Casement windows can be one of the easiest window replacements for adding ventilation. It gives the choice to have an air-tight seal, or smooth gradual dispersed air ventilation during pleasant weather. If you want to replace old windows with energy efficient windows that give you choice and added light, consider casement windows.
Delco Windows and Doors also installs casement windows across Toronto, starting with a free in-home consultation before anything is ordered.
Casement windows can give your home a look of permanence and long-term design. Because these windows are set in place, with no mechanical operations, and no multiple panels, they look "built-in" and permanent. Casement windows have the power to make a home look long-lasting, and stable.

Specially designed for Toronto’s climate, LoE-180 keeps your home warm on the inside, when it is freezing on the outside. It allows more of winter’s sunlight to pass through into the home, creating passive solar heating, while blocking heat loss during the night. By using a unique coating on the outside of the window, Cardinal’s LoE-180 windows creates a thermal barrier that help make your home fully insulated, while having plenty of natural light. This is the highest base standard glass for Canadian climates throughout Toronto, the GTA, and Ontario areas. It raises the bar and creates the new EnergyStar standard for all of Canada. Delco is proud to have LoE-180 as its standard glass package for new window installations. This window technology will help make your home a cozy, warm and comfortable home year round.

 | LOE-272Year-round comfort for your home. Cardinal’s LoE-272 window glass helps your home to be warm and cozy in the winter, and cool and comfortable in the heat of the summer. It offers that right balance needed for your home. While Toronto’s winters can be cold, summer days can be downright uncomfortable. Windows themselves can transmit temperature to the touch, causing energy loss. LoE-272 nearly eliminates this problem. In winter, LoE-272 reflects heat back in the room. In summer, it reduces heat gain from the window by preventing heat absorption of the window itself. Saving you on your summer air conditioning costs, while reducing winter heating costs. This give the opportunity to have all-year energy savings at its highest level.

 | LOE-366 by Cardinal or LE6 by GuardianTHE NEW OUTSTANDING WINDOW GLASS for ultra high-efficiency homes. LoE-366 delivers the ideal balance of solar control and high visibility. And it provides the highest levels of year-round comfort and energy savings, making it the perfect glass for homes in the Toronto area. What makes that happen? A unique technology using a triple layer of silver. The coating is clear, yet blocks even more summer solar gain, yet reflects winter heat back into your home. Bright, well lit, and comfortable . . . all year long. Also, LoE-366 offers the highest in fading protection. It blocks 95% of the sun’s damaging UV rays, a major cause of furniture, curtains, paint and floor fading. LoE-366 not only protects your energy bills, but extends the life of your home’s cherished items. Lastly, by reducing temperature differences on the glass, it reduces humidity buildup. The benefits are endless! If you want to let light in, while avoiding the negative effects of tinting, LoE-366 is for you. Ideal for modern homes, off-grid, or homes seeking to be near zero-emissions. This is the ultimate standard in energy efficient windows for homes around Toronto. And Delco is happy to offer this upgrade to any window installation package.

What sets this glass apart is its enhanced winter performance for northern latitudes like much of Canada. It allows even more natural light in, while reducing heat loss than our standard glass package. It reflects your interior heat back into your home.

 | Triple GlassTriple-pane glass gives you the highest energy efficiency through multiple layers of insulation in your window panes. Three Panes, separated by your choice of gas-filled or standard spaces. More deluxe than double-pane windows, triple-pane gives you a superior insulation factor. This provides the ultimate in high-efficiency window technology.

 | Neat®With the Neat® glass option, you gain natural cleaning convenience. By harnessing the sun’s UV rays (even when the sky is cloudy) to loosen dirt from the glass, rainwater can easily rinse away grime. Living in Canada, you know how dirt, rain and snow can be hard on windows. Why not let nature clean your windows?
|
 | PreservePreserve® film is standard, and factory-applied to both the interior and exterior surfaces of the glass of many of our windows. This means the glass surfaces will be protected from dirt and scratches that could occur during shipping and handling or at a construction site of your home. No need to spend extra time cleaning your new windows. With easy quick removal, your windows will be spotless from day one.
|
 | Laminated GlassHave the ultimate in protection from window breakage with Laminated Glass. By building in an interior transparent plastic vinyl layer, broken shards of glass will stay adhered to it and reduce the problem of glass pieces. It also strengthens the window itself. Laminated glass is offered as an upgrade to many of Delco’s window installation packages.
|
 | Tempered GlassThe tempered glass option is available in all glass types and provides extra strength, enabling it to withstand force or pressure on its surface and it will not break into sharp pieces and glass splinters. If ever broken, the glass will split in a safer way. Many local building codes in and around the GTA often encourage or require tempered glass to be used in all windows that are close to the floor or near doors, tubs, or showers.

SAFEGARD CASEMENT WINDOW OPENING CONTROL DEVICE [WOCD]
The industry’s first casement – Window Opening Control Device (WOCD) that meets the requirements of ASTM F2090-10. This innovative hardware system provides safe and secure operation of egress style windows critical in today’s building projects. Multiple safe guards are in place to help control the window opening to prevent accidental falls while at the same time allowing easy operation in the event of an emergency. Typical operation limits the opening of the sash to less than 4″. An additional operation is required to open the window fully for egress purposes. This additional operation can be performed without the use of keys, or special tools and the SafeGard™ casement – WOCD will automatically re-latch when the sash is fully closed.
 | FIBERGLASS MESH (STANDARD)Our standard charcoal fiberglass mesh insect screens for windows keep insects outside, while letting in natural light. The frames are available with colors to match the patio door color you choose. All window and door screens are not safety and security device, but work well to keeping insects out while letting air and light in. |
 | BETTERVUEFor the best view with a screen, BetterVue™ screens are designed to let more natural light inside compared to regular screens. BetterVue insect screens feature fine, black fiberglass mesh with a light gloss finish, and the frame is available to match the window color you choose. Keep insects out, but let the most light and view in. |

Casement window installation in Toronto with Delco Windows and Doors starts with one question: will the new sash have room to swing? Have you looked at what sits outside that window right now: a porch rail, a downspout, a bush pressed against the wall?
A casement is hinged on the side and opens outward, so the fitting work is different from a sliding or hung window. Here is what happens on the day.
Our in-house installers, with no subcontractors, remove the old sash, stops and trim, then check the opening for rot, damage, and squareness. A casement seals by pressing the sash against the frame, so an opening that is even slightly out of square shows up later as a draft or a handle that will not close. We shim and level the frame until the gap is even on all four sides before anything is fastened.
The frame is then fixed through the jambs, with extra fastening on the hinge side, where the weight of an open sash pulls hardest. Insulation fills the gap around the frame and sealant goes on the exterior. Then the sash is hung, the multi-point lock is checked along its full length, and the handle is tested. The sash opens a full 93 degrees, so we confirm it clears the wall, the screen, and anything outside.
Expect some noise and a few people moving through the room. Furniture near the window is moved, floors are covered, and the space is left clean. You can read how our full window installation in Toronto service works from first visit to final check.
Replacement casement windows in Toronto are fitted in one of three ways.
Insert replacement keeps the existing frame and fits the new casement inside it. It is the least disruptive and works when the old frame is sound and square.
Full-frame replacement removes everything down to the rough opening. It is the right call when the frame has rot, water damage, or has moved out of square, and it lets us insulate and seal the whole perimeter properly.
New or resized opening applies when you are swapping a sliding or fixed window for casements, or adding ventilation where there was none. It needs more framing work and can bring in the permit question below.
During the assessment, we look at your frames and tell you which method applies to each window.
What happens if a casement stops closing properly a year from now? Delco Windows and Doors has been making and installing windows since 1989, more than 35 years, and our own team handles aftercare, including adjustments to hinges, handles, and locks. Our lifetime, fully transferable, non-prorated warranty covers frames, sealed glass, hardware, and components, so a failed seal or worn hardware is not a bill you carry. Homeowners rate us 9.8/10 on HomeStars and 4.9/5 on Google. Because we design, manufacture, install, and follow up ourselves, you deal with one company instead of coordinating three.

Most Toronto homeowners wait longer for their windows to be made than for them to be installed. The usual order is a free in-home consultation, exact measuring of each opening, manufacturing of your custom casements, then installation. Manufacturing takes the most calendar time, because each window is built to your opening size, glass package and colour. Installation itself is usually quick: a single casement is often a matter of hours, and a whole house can take a few days. Delays most often come from a late design decision, an opening that needs repair once the old window is out, or weather that stops exterior sealing. Deciding on colour and glass early keeps the job moving.
Often not, but it depends on what you change. In Toronto, replacing a casement window in the same opening at the same size generally does not need a building permit. Making an opening larger or smaller, or adding a new one, is structural work and usually does. Homes in a heritage district or on the heritage register can face extra approval for visible exterior changes, and condo owners usually need board approval before the outside of the building changes. Confirm the rules with the City of Toronto or your board before you order. We go over your openings during the free consultation, so you know which category your project falls into before any work is booked.
The cost depends on your windows rather than a flat rate, and the free in-home consultation gives you a clear price with no obligation. Several factors move it. The size and number of openings come first, since larger casements and more windows raise the total. Your glass package matters next, because Low-E and Argon options change the price. Colour and finish, hardware, and screens add to it. The condition of the opening counts too, because rot or damage has to be repaired before the new frame goes in. Access also plays a part, as upper floors and tight exteriors take more time. Changing a sliding window to a casement can add framing work compared with a like-for-like swap. Ask for the assessment, and you will see each factor priced for your home.
Yes, in most cases. A casement opens outward on a hinge, so the opening may need adjusting, and you need clear space outside for the sash to swing. We check both during the free in-home assessment and tell you if a different method suits that window better.
Expect noise and some dust while old windows come out. Our installers cover floors, move nearby furniture, and clean up when they finish. It helps to have someone home at the start and the end, so we can show you how the handle, lock, and screen work.
Not always. If your existing frame is sound and square, an insert can work. If there is rot or movement, a full-frame replacement is the safer choice. We check the frame before we give you a price.
Yes. Casement windows are usually a strong choice for Toronto homes because the sash presses tightly against the frame when closed. That helps reduce air leakage compared with older loose sliding or hung windows.
Practical solution: Use casement windows in rooms where drafts are a real problem, especially bedrooms, living rooms, and upper floors exposed to wind. The final performance still depends on accurate measuring, insulated glass, weatherstripping, and proper installation around the opening.
A crank window can become stiff when the operator, hinge, sash, or frame is worn, shifted, rusted, or out of alignment. In older Toronto homes, settlement and repeated freeze-thaw movement can also make the sash harder to operate.
Practical solution: If the glass and frame are still solid, hardware adjustment may help. If the sash is warped, leaking, or no longer seals evenly, replacement casement windows are usually the cleaner long-term fix.
Often, yes. Because casement windows open outward from the side, they can catch passing air and direct it into the room. This can help in kitchens, bedrooms, and rooms that feel stale during mild weather.
Practical solution: Choose the hinge side and opening direction based on wind direction, furniture placement, walkway clearance, and exterior obstacles. A wrong swing direction can reduce the airflow benefit or create clearance problems outside.
Casement windows can be a secure option when they include strong hardware, proper locking, and a tight frame. Multi-point locking is especially useful because it engages more than one locking point with a single handle.
Practical solution: For ground-floor rooms, side yards, and basement-adjacent openings, ask about the locking system, glass type, restrictors where appropriate, and whether the window style meets the room’s safety and egress needs.
Not always. Casement windows are strong for sealing, airflow, and clear views, but they are not the right fit for every location. Exterior walkways, patios, shrubs, railings, and tight side passages can limit how well an outward-opening window works.
Practical solution: Use casement windows where airtightness and ventilation matter most. For tight exterior spaces or openings beside walkways, compare awning, slider, picture, or hung window styles before finalizing the replacement plan.
Still wondering whether your windows can take casements, what it will cost, or how much of your week it will disrupt? One short visit settles all three. Request a free in-home consultation, and a Delco expert will assess your openings and give you pricing for replacement casement windows in Toronto, with no obligation.
