A gap between the top and bottom of the sash, and the jamb frame, is an issue that is frequent. This can cause moisture to leak into the wood, which can cause rotting, and mold growth. Seal the gap with silicone, polyurethane or foam sealant.
Installing a new sash runner or spring bronze could be necessary when a gap is preventing the windows from closing and opening easily.

Unscrew the sash stoppers (a thin vertical strip of wood that supports the sash) and then loosen any painted-covered hardware. Pull the sash to reveal the balancing weight that is a massive iron cylinder that is encased inside a hidden compartment and secured by a rope. To stop the sash falling into the void, make a hole in it using nails and remove the weight.
Once the sashes are free clean the jamb and rails that meet, remove the glazing bars and sash cords and remove any paint off the sash stops using a utility knife. Reattach the stops when the sashes have been reinstalled. Use nails that are not large enough to puncture the weight of the balancing.
