Before you start, it’s vital to understand safety precautions to prevent injury and avoid damaging the window or surrounding frame.

During your window restoration process, take the time to inspect these parts thoroughly. If any are damaged, replacing them might be necessary before you can fully unstick the window. When working on the sash, gently wiggle and lift it, applying even pressure to avoid putting stress on the glass or frame.
