Are casement windows more energy efficient than sliders?

Generally yes. Because a casement sash clamps tightly against the frame when you crank it shut, it seals better than a sliding window, which relies on brush weatherstripping. Paired with triple-pane Low-E glass, our casements are among the most efficient windows we supply.

Do you make casement windows to custom sizes?

Always. Since every casement is custom-made to order, it is built to your exact opening — there are no standard-size compromises. That also means a cleaner fit and better sealing during installation.

How do I clean the outside of a casement window?

The sash opens a full 90 degrees, leaving a gap on the hinge side that lets you reach the exterior glass from inside. This makes casements ideal for second-storey and hard-to-reach openings.

How long from quote to installation?

After your free in-home measurement, your custom order typically takes 3 to 5 weeks. Installation of a set of casement windows is usually completed in one to two days.

What does a casement window cost?

Price depends on size, glass package, grilles, and colour. Because we supply and install directly, our pricing is fair and direct. Call (647) 865-3371 or request a free in-home quote above.

Why Casement Windows Are Our Best Seller

A casement window is hinged on the side and swings outward with the turn of a crank. Because the sash presses tightly against the frame when closed, casements form one of the most weathertight seals of any operable window — which is exactly what you want in the Canadian climate.

They also open fully, so you get maximum ventilation and a clear, unobstructed view with no sash bar across the middle. For most Ontario homes, casements are the ideal balance of energy performance, easy operation, and clean modern looks.

Built to Withstand the Canadian Climate

Every casement we supply is engineered for our winters and summers:

Multi-chambered vinyl frame that insulates and resists condensation
Double co-extruded bulb seal for added insulation value
Quiet triple-fin weather seal on the sash to virtually eliminate air infiltration
Double or triple-pane Low-E glass with argon gas fill
Fusion-welded frame and sash corners for lasting strength
Never needs painting — will not rot, warp, or corrode

Effortless Operation & Easy Cleaning

A premium low-profile nesting crank handle folds flat when not in use, so it never interferes with blinds or window treatments. The 90-degree sash opening lets you clean the exterior glass safely from inside your home — a real advantage on upper floors.

Smooth, corrosion-resistant crank operator with multiple finish options
Multi-point locking system for added security
Easily removable smooth-edge screen with hidden retention system
90-degree opening for easy interior cleaning of the outside glass

Glass, Grille & Colour Options

Because your windows are custom-made to order, you choose exactly how they look and perform. We help you select the right glass package for comfort and efficiency, add optional grilles for a traditional look, and match frame colours to your home.

Double or triple-pane sealed glass units with Low-E coatings
Argon or krypton gas fill for higher insulation values
Tempered or laminated glass where safety or sound control matters
Full selection of grille and divided-lite patterns
Interior and exterior colour and woodgrain options

Supplied, Sold & Installed by One Local Team

We custom-order your casement windows to your measurements, then our own installers remove the old units, fit the new windows, seal and insulate the openings, and clean up completely. One accountable family business from quote to finished install — with a warranty that stands behind every window.

"We replaced every window in our two-storey home with WindowFixers casements. Because they cut out the middleman, the price beat the big brands and the quality is excellent. The house is warmer and noticeably quieter."
