Casement Windows in Lansing: Crank-Out Windows That Seal Tight

A casement window is hinged on one side and opens outward with a crank, like a door. When it closes, the sash presses against the weatherstripping on all four sides, and wind blowing on the glass only pushes it tighter. On a gusty January day in Lansing that difference is easy to feel next to an older sliding or double-hung unit.

Where Casements Work Best

• Over the kitchen sink, where reaching up to lift a sash is awkward
• Beside a deck or porch, to scoop in a cross breeze
• In basement egress openings, where a full-width opening matters
• Paired with a large picture window for a clean, modern look
• As awning windows, hinged at the top, under or above other glass

Things to Know Before Choosing Casements

Casements swing outward, so they are not ideal right next to a walkway or a deck where people might walk into an open sash. Screens go on the inside. The crank and hinge hardware does the work, so we install units with sturdy operators and show you how to keep them running smoothly season to season.

Installation Matters

A casement only seals as well as it is set. The frame has to be square and plumb, or the sash will drag and leave gaps. We shim every corner, check the reveal all the way around, fill the gap between frame and rough opening with low-expansion foam and finish with exterior flashing and sealant. Then we open and close each unit to make sure the lock pulls it fully closed.

Frame Materials

Casements are available in vinyl, fiberglass, wood and clad-wood frames. Vinyl keeps maintenance low, while clad wood suits older homes in Moores River Drive or Colonial Village where interior wood trim matters. Our vinyl window page covers that option in more detail.
