Sealing
Sash windows can look stunning in old buildings, however they require regular maintenance and are susceptible to issues such as cracked putty, wet rot, and draughts. Repair, sealing, or replacement of the sash window is an effective method to eliminate these issues and increase energy efficiency.
Draughts are mostly caused by gaps between the sash and the frame. They can also cause rattles and reduce sound-proofing. Sealing beads, special products, and secondary glazing can be used to limit the air leakage in the Sash.
A gap between the top or bottom of the sash, and the jamb frame, is an issue that is common. This can cause moisture to leak into the wood, which can cause rotting and the growth of mold. The gap can be filled with caulking made of polyurethane or silicone or foam sealant.
If a gap in the window is preventing the windows from closing and opening smoothly, it may be necessary to put in new sash runners or spring bronze. These strips of bronze are attached by staples or nails to the sash's lower edges to stop sideways rattling. They can be purchased at DIY stores. Tubular vinyl weather-stripping is another option but it has a tendency to rip, and it can make a difference to the appearance of windows.
When replacing sash runners, it is important to measure the window opening. It is recommended to take measurements from the top of the sash up to the horizontal centerline of the rails that meet and from the bottom of the sash down to the sill. These measurements can be incorporated into the new runners, which will ensure a proper fit and better operation of the window.
In older buildings, there is a wider gap between the sash and frame around the leading edge. It is possible to draught-proof it using strips of V-strip that is self-adhesive. However, it is important to take this into account when cutting and measuring material.
A strip must be cut to the length of the sash. There should be an extra inch to allow for movement. It should be trimmed squarely and placed to match the angle of the sill. Make sure to use stainless steel screws since brass will be rusty. Also, use high-quality polyurethane or silicone glue.

It is crucial to determine whether to replace or repair windows that are damaged, as each choice will require a different level and level of expertise.
