Draughts are mostly caused by gaps between the sash and the frame. They can also lead to rattles and reduce sound-proofing. Various methods can be used to limit air leaks within windows with sash, including sealing beads, specialist products, and secondary glazing.
A gap between the top or bottom of the sash and the jamb frame is an issue that is frequent. This can cause moisture leaking in the wood, rotting and the growth of mould. The gap can be sealed with silicone or polyurethane caulking or foam sealant.
Installing new sash runner or spring bronze might be required when a gap is preventing windows from closing and opening easily.

Remove the sash stops (a thin vertical strip of wood that is used to hold the sash) and then loosen any paint-encrusted hardware. The sash should be pulled back to reveal the weight. It is a large iron or lead cylinder that is hidden in a cavity, and supported by a cord. To stop the sash falling into the void, make a hole in it using an hammer and then sacrifice the weight.
