A common problem is a gap that exists between the top of the sash and the jamb frame or between the bottom of sash and the sill. This can lead to moisture leaking into the wood, rotting it and growth of mold. The gap can be filled by caulking made of silicone or polyurethane or foam sealant.
If a gap is preventing the windows from opening and closing without a hitch, it might be necessary to replace spring bronze or sash runners.
