Sealing
Sash windows look stunning in older structures, but they require care. They can be affected by issues such as wet-rot, cracked putty, and draughts. Sealing, replacement or repair of the windows sash is an effective method to minimize these issues and improve energy efficiency.
The gaps between the sash and frame are the primary source of draughts. They can also trigger rattling and reduced sound-proofing. There are a variety of methods to limit air leaks within the sash window, such as sealing beads, specialty products, and secondary glazing.
A gap between the top and bottom of the sash and the jamb frame, is an issue that is common. This can cause the leaking of moisture, rotting of the wood and growth of mould. Seal the gap with silicone, polyurethane, or foam sealant.
If a gap is preventing windows from closing and opening easily, it could be necessary to put in new spring bronze or sash runners. These are a type of bronze that are stapled or nailed into the edges of the lower sash in order to prevent sideways rattle. They are available at DIY stores. Tubular vinyl weather-stripping is an alternative option, but it can rip, and it can make a difference to the appearance of windows.
When installing replacement runners for sash, it is important to measure the entire width of the window opening. It is best to measure from the top of sash up to the horizontal centerline of the rail of the meeting and from the bottom of sash down to the sill. These measurements can be transferred to the new runners, which will help ensure a good fit and better operation of the window.
In older buildings there is a greater gap between the sash as well as the frame around the leading edge. It can be draught proofed by using a self-adhesive Vstrip, however it is crucial to consider this when measuring and cutting the material.
A strip must be cut to the length of the sash, and with an extra inch to allow movement. It should be cut square and positioned in a way that the ends are matched to the angle of the window sill. It is also crucial to make use of stainless steel screws since brass can rust and high-quality silicone or polyurethane adhesive.
Refurbishment
The sash window is an elegant, historic feature of many homes. They are beautiful, but they can be susceptible to issues. Common issues include rattling stickiness or draughts.

Refurbishment is more costly than replacing the sash, however, it can bring back the appearance and functionality to the same level in its original condition. Refurbishment involves lining the meeting rail as well as the sash box with traditional putty, and repairing any damage caused by decay. It also involves painting the frame with timber and reglazing with 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). In addition, it is recommended to install brush pile weather strips in order to minimize the rattling and increase insulation.
If you require a new sash it can be constructed from similar designs to the old frame and maintain the character of your house. This is especially important for listed buildings where any modifications to windows will require planning permission.
Before putting the new window on before installing it, make sure you check the metal tabs against those on the sash that was previously used (see below). If they are different shapes, the new sash will not fit inside the window frame slots.
It is important to decide if you want to replace or repair a damaged window, as each will require a different level and level of knowledge. If a large part of the glass in a sash is missing replacing it would be an alternative. However when the glass has been damaged in one small section or a sill has begun damaged, a repair would be the better option.

Remove the cords and chains from both sides. Lastly, remove the sashweights from the bottom cavity of the weight. Store the hardware in a secure location. The heat gun will soften old, hardened filler or putty. Scrape it away with the blade of a putty.

Unscrew the sash to reveal the balancing weight which is a heavy iron cylinder or lead that is enclosed inside a hidden compartment and secured by rope.
