Sealing
Sash windows can look stunning in older buildings, but they require maintenance and are susceptible to issues such as cracks in putty, wet rot, and drafts. It is possible to decrease energy loss and improve the efficiency of windows with sash by replacing them, repairing or sealing them.
Draughts are mainly caused by gaps between the sash and the frame. They can also cause noise reduction and rattle. Different methods can be employed to reduce air leaks in a sash window, including sealing beads, specialist products, and secondary glazing.
A common problem is a gap between the top of the sash and the jamb frame or between the bottom of sill and the sash. This can cause moisture leaking in, rotting of the wood, and mould growth. The gap can be filled with silicone or polyurethane caulking or foam sealant.
If a gap is preventing windows from closing and opening smoothly, it may be necessary to replace spring bronze or sash runners. These strips of bronze are stapled or nailed to the lower sash edges to stop the rattling of the sides. They are available at DIY stores. Weatherstripping made of tubular vinyl can also be used, however it is prone to tear and may alter the look of your window.

In older buildings the gap between the frames and sash is typically greater around the leading edge. It can be draught-proofed using a strip of V-strip which is self-adhesive. However, it is important to take this into consideration when measuring and cutting material.
A piece of material should be cut to the height of the sash, with an extra inch each side to allow to allow movement. It should be trimmed square and placed so that the ends are aligned to the angle of the window sill. Use stainless steel screws since brass will be rusty.

It involves lining the meeting rail and sash boxes with traditional putty and fixing any rot damage. Re-painting the frame of the timber is also included, as is re-glazing using traditional glass. A full refurbishment can also include adding draught proofing, re-attaching the sash furniture/ironmongery and replacing the parting bead (the dividing strip between the two panes of glass). Finally, it's recommended to put in brush pile weather strips to reduce rattling and improve insulation.
If you require a new sash, it can be made from like-for-like designs to match the frame of the previous one and preserve your property's heritage style. This is especially important for buildings that are listed, as any changes to the windows need planning permission.
Before putting the new window in place before installing it, make sure you examine its metal tabs with the tabs on the old sash (see below). If the tabs are different shapes, the new sash will not fit properly into the window frame slots.
It's important to decide whether to replace or repair windows that are damaged, as each will require a different level and amount of knowledge. For instance, if a sash window has a significant piece of glass missing then replacing it is the best choice.

The process of bringing the window apart starts with the removal of any security fittings in front of the lower sash. Then, take off the staff bead. Then, remove the sash at the bottom.

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 weight balancing, which is a heavy iron cylinder or lead that is enclosed in a concealed cavity and held by a rope. To prevent the sash falling into the void pierce it using a nail, and then sacrifice the weight.
