Sealing

The gaps between sash frame are the primary cause of drafts. They can also cause rattling and reduced sound-proofing. Sealing beads, specialty products, and secondary glazing may all be used to minimize the air leakage within the sash.
A common problem is a gap between the top of the sash and the jamb frame, or the bottom of the sash and the sill. This can lead to water leaking into the wood, rotting of the wood and growth of mould. Seal the gap with silicone, polyurethane or foam sealant.
If a gap is hindering windows from opening and closing smoothly, it may be necessary to install new sash runners or spring bronze. These bronze strips are tied or stapled to the sash's lower edges to stop sideways rattling. They can be purchased at DIY stores. Tubular weatherstripping also can be used, but it is more likely to tear and may alter the look of your window.

It is best to take measurements from the top of the sash to the horizontal line of the meeting rail and from the bottom of the sash down to the sill. These measurements can later be transferred to new runners that will ensure a better fit and operation of the window.
In older structures there is a larger gap between the sash and frame around the leading edge. It can be draught-proofed by using a self-adhesive V-strips, but it is crucial to account for this when measuring and cutting the material.
A strip must be cut to the width of the sash. There should be an extra inch for movement. The strip should be cut square and positioned in a way that the ends are aligned to the angle of the window sill.

When a window is damaged it's essential to choose between replacement or repair, because each type of work will involve a different level of expertise and price.
