Draughts are mainly caused by gaps between the sash and frame. They can also cause rattling and reduced sound-proofing. Sealing beads, specialty products and secondary glazing can all be used to minimize the air leakage inside a shutter.

A gap between the top or bottom of the sash, and the jamb frame is an issue that is frequent. This can lead to the leaking of moisture, rotting of the wood and the growth of mould. Seal the gaps with silicone, polyurethane, or foam sealant.

Installing new sash runner or spring bronze may be required if a gap prevents the windows from closing and opening easily. These strips of bronze are stapled or nailed to the lower sash edges in order to prevent sideways rattling. They can be bought at DIY stores.

In older buildings the gap between frames and sash is typically larger around the leading edge. It can be draught-proofed using a strip of V-strip that is self-adhesive. However, it is important to consider this when measuring and cutting material.

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

It's important to decide whether to repair or replace the damaged window, since each option will require a different degree and level of expertise.

Unscrew the sash stops (a thin vertical strip of wood that is used to hold the sash) and then loosen any painted-covered hardware. Unscrew the sash to reveal the balancing weight, which is a large iron cylinder that is encased inside a hidden compartment and anchored by a rope. To stop the sash from falling into the void, you must pierce it using a nail, and sacrifice the weight.
