Sealing

Draughts are mainly caused by gaps between the sash and frame. They can also lead to rattling and reduced sound-proofing. Various methods can be used to reduce air leaks in windows with sash, including sealing beads, specialty 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 to leak into the wood, rotting it and the growth of mold. Seal the gaps with silicone, polyurethane, or foam sealant.
Installing a new sash runner or spring bronze might be necessary when a gap is preventing windows from opening and shutting effortlessly. These strips of bronze are tied or stapled to the lower sash edges to prevent sideways rattling. They can be purchased at DIY stores. Weatherstripping made of tubular vinyl can also be used, but it is prone to tear and can detract the appearance of your window.

It is recommended to take measurements from the top of sash up to the horizontal line on the rail that connects them and from the bottom of sash down to the sill. These measurements can be transferred to the new runners, which will help ensure a proper fitting and better operation of the window.
In older buildings the gap between frame and sash is typically wider around the leading edge. It can be draught-proofed by using a self-adhesive V-strip, but it is essential to consider this when measuring and cutting the material.
A piece of material should be cut to the width of the sash, with an extra inch on each side to allow for movement. It should be trimmed squarely and positioned in accordance with the angle of the sill. Use stainless steel screws as brass will rust. Also, make sure you use high-quality polyurethane or silicone glue.

If a new sash is required the frame can be constructed from like-for-like designs to match the frame that was previously used and keep the character of your house. This is particularly crucial for listed buildings, where any modifications to windows require planning permission.
Compare the metal tabs of the new window with those of the old sash before installing it (see below). If they're different shapes and sizes, the new sash will not fit in the window frame slots.
If a window has been damaged, it is essential to decide between repair or replacement, since each kind of repair will require a different level of expertise and price. For example when a sash window has a significant piece of glass that is missing, then replacing it is the best option.
