A gap between the top and bottom of the sash, and the jamb frame, is an issue that is common. This can lead to moisture leaking into the wood, which can cause rotting and growth of mold. The gap can be filled with caulking made of polyurethane or silicone or foam sealant.

If a gap in the window is preventing windows from closing and opening without a hitch, it might be necessary to install new spring bronze or sash runners.

Tubular weather-stripping made of vinyl is a different option but it is prone to tear and affect the appearance of windows.

It is best to measure from the top of the sash to the horizontal centerline of the rail that connects it and from the bottom of the sash down to the sill.
