How to Fix Drafty Windows Without Replacing the Entire Frame

Locating Air Leaks in Windows

When a window feels cold, rattles in the wind, or lets air move around the sash, the frame is not automatically the problem. It matters because a good frame can often stay in place while the weak points around the sash, trim, or hardware get fixed.

The first step is figuring out where the air is actually coming from. Homeowners often assume the whole window has failed, when in reality the air leak may be limited to one worn component.
