Casement windows are hinged on one side and open outward with a crank, rather than sliding vertically or horizontally. That hinge-and-crank design lets the sash press firmly against the frame when closed, which typically gives casement windows a tighter seal than sliding styles.
They work particularly well over sinks, counters, or other spots where reaching a sash to slide it would be awkward, and their outward swing catches passing breezes more effectively than a sash you simply raise. On Long Island, where wind off the Sound or ocean is a real factor, that ventilation angle is worth considering.
Casement windows work best where their outward swing won't be obstructed by decks, walkways, or shrubs, and where the tighter seal and ventilation angle are worth prioritizing. They're less ideal directly next to high-traffic walkways since the open sash projects outward into the space.
One hinged sash covering the full window opening, common for standalone windows in bedrooms, kitchens, and bathrooms.
Two casement sashes hinged on opposite sides that meet in the middle, opening to leave no center frame obstructing the view when closed.
A fixed window above a crank-operated casement sash, adding height and light without adding operable area near the top.
An alternative to crank hardware where the sash is unlatched and pushed open by hand, preferred by some homeowners for simplicity.
Various interior screen configurations to keep bugs out while the sash is open, since the screen must sit inside the swing path.
We check clearance around the proposed opening to confirm the outward swing won't hit a deck rail, shutter, or landscaping.
You choose crank or push-out hardware, single or paired configuration, and any transom addition based on the specific opening.
Precise measurement of the existing or new rough opening ensures the casement frame and sash fit and seal correctly.
The frame is set level and plumb, since casement sashes are more sensitive to an out-of-square frame than sliding styles.
We test the crank mechanism through a full open-close cycle and confirm the sash compresses evenly against the weatherstripping.
Sealant and flashing are applied around the frame perimeter to keep water out, particularly important given the sash's outward orientation.
Casement windows involve crank hardware and typically a heavier sash than sliding styles, which factors into pricing along with frame material and glass package. Paired configurations and transom additions add complexity. We quote after measuring your specific openings rather than using a flat per-window number.
Get an EstimateCasement frames need to go in level and square more precisely than sliding styles, since an out-of-square frame shows up immediately as a sash that won't seal evenly. We take the extra care in setting the frame that this window style requires.
