Cold draft? Learn how to properly lock your windows
You might be surprised how much comfort you can lose from a window that isn’t fully locked.
In this short video, you’ll learn how to check your window sashes to make sure they’re properly aligned. When the top sash isn’t pushed all the way up or the bottom sash isn’t fully closed, the lock may not engage, allowing drafts and noise to slip in.

A common but often overlooked issue in many homes is improperly locked windows. Because the problem isn’t always obvious, homeowners may not realize their windows are letting in drafts or outside noise, especially during colder months.
Most standard windows have two movable panels, known as sashes. The top sash is designed to slide up and down, but it is not always pushed fully into place. When this happens, the window may appear closed but isn’t properly aligned for the lock to engage. As a result, cold air, drafts, and even sound from outside can seep into the home.
During the winter, this issue becomes more noticeable when a room feels chilly or unusually noisy near the windows. To ensure a proper seal, the top sash should be pushed all the way up, while the bottom sash should be pushed completely down. Once both sashes are fully in place, the lock at the center should align correctly.
After locking the window, it’s important to double-check that everything is secure. Try gently lifting or lowering each sash to confirm they cannot move. When both sashes are properly aligned and locked, the window will seal more effectively, helping to reduce drafts, improve comfort, and maintain a quieter indoor environment.
By taking a moment to check window alignment and locks, homeowners can improve energy efficiency and comfort with a simple adjustment that requires no tools or repairs.
