Here are some of the most common failures with casement window parts.
Crank Mechanism Failure
The window crank is one of the most crucial elements of any casement window. This is what helps your window swing open for air circulation. There is usually a gear mechanism that allows the crank to push open the window sash. However, it is possible for your window crank to fail, inhibiting the opening of the window.
There are a few reasons your window cranks may fail:
- Rusting: Rusting occurs when metals interact with water and oxygen to create a red, dry, flaky buildup that is rust. This issue is especially common if you live in a moist or humid environment. Rust can make your window crank very stiff and difficult to open.
- Stripped Gears: The gears inside your window crank can simply wear down and break over time, preventing them from working at all.
- Broken Handle: If you apply too much force to your window crank handle, it can break or become misshapen. This will prevent you from being able to open your window.
While you can try to remedy a stiff window crank with some lubricant, damaged gears and crank handles require replacement of casement window parts to fix.
Hinge Issues
Your window hinges are what actually support the window and allow it to open while remaining connected to the window frame. Since the window hinges carry the full weight of the window sash, they are prone to damage.
A few different hinge issues may occur:
- Warped Hinges: Your window hinges can bend and warp when exposed to pressure from intense winds. This damage is permanent and can prevent the sash from swinging out.
- Corroded Hinges: When exposed to water, window hinges can corrode and rust, leading to significant stiffness that can make it challenging to open the window.
- Loose Screws or Mounting Brackets: Movement and stress can loosen fasteners and screws, leading to sagging or misalignment.
Locking Mechanism Failure
The locking mechanism ensures the window is adequately secured when closed, playing a key role in both home security and insulation. Most casement windows have a single latch for a lock. Given how small these features tend to be, it can be easy to damage them.
Common issues with window locks include:
- Misalignment: Physical trauma can cause your window lock to become crooked and misaligned. This will prevent it from engaging properly, posing security issues.
- Broken Locking Arms: These small components can snap or warp with age or excessive force.
