Sealing
Sash windows look stunning in older structures, but they require regular maintenance. They are susceptible to issues such as wet-rot, cracked putty and draughts. It is possible to decrease energy loss and improve the efficiency of windows with sash by replacing them the windows, repairing or sealing them.
Draughts are usually caused by gaps between the sash and the frame. They can also lead to noise reduction and rattling. Sealing beads, specialty products, and secondary glazing may be used to limit the air leakage in the sash.
A common issue is a gap between the top of the sash and the jamb frame or the bottom of the sash and the sill. This can cause the leaking of moisture and rotting of the wood and growth of mould. The gap can be closed with silicone or polyurethane caulking or foam sealant.
Installing a new sash runner or spring bronze might be necessary if a gap prevents windows from closing and opening smoothly. These bronze strips are tied or stapled 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 detract from the appearance of windows.
It is crucial to take measurements of the entire window opening before installing replacement sash runner. It is best to take measurements from the top of the sash up to the horizontal centerline of the rail that connects it, 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 a better performance of the window.
In older buildings the gap between the frame and sash is typically larger around the leading edge. It can be draught-proofed using strips of V-strip that is self-adhesive. However it is essential to take this into consideration when measuring and cutting material.
The strip should be cut at the height of the sash, with an inch more on each side to allow for movement. It should be squarely trimmed and positioned to match the angle of the sill. Use stainless steel screws since brass can be rusty. Also, use the highest quality polyurethane or silicone glue.

When a window is damaged it's essential to choose between repair or replacement because each type of work will involve a different level of expertise and price. If a large part of the glass in a sash is missing, then replacing it will be a better option.

Unscrew the sash stops (a thin vertical strip of wood that supports the sash) and then loosen any painted-covered hardware. Unscrew the sash to reveal the balancing weight which is a heavy lead or iron cylinder enclosed inside a hidden compartment and held by rope. To stop the sash from falling into the void pierce it using a nail, and then let the weight go.
Once the sashes are free, clean out the jamb and meet rails. remove the glazing bars and sash cords, and scrape off any paint from the sash stops using a utility knife.
