A common issue is a gap between the top of the sash and the jamb frame or the bottom of the sill and the sash. This could cause moisture to leak into the wood, rotting it and growth of mold. The gap can be filled with caulking made of polyurethane or silicone or foam sealant.

Installing new sash runner or spring bronze might be required if a gap prevents windows from opening and shutting effortlessly.

In older buildings the gap between frame and sash is typically larger around the leading edge. It is possible to draught-proof it using strips of V-strip that is self-adhesive. However it is crucial to take this into consideration when measuring and cutting material.

The strip should be cut to the height of the sash and with an inch more on each side to allow for movement. It should be squarely trimmed and placed to align with the angle of the sill.
