Sealing
Sash windows look gorgeous in old buildings but they require maintenance and are susceptible to issues like cracked putty, wet rot, and drafts. Repair, sealing or replacement of the sash window is an effective way to reduce these problems and improve energy efficiency.
Draughts are mostly caused by gaps between the sash and frame. They can also cause rattling and reduced sound-proofing. Sealing beads, specialist products, and secondary glazing can be used to limit the air leakage within the sash.
A common issue is a gap that exists between the top of the sash and the jamb frame or the bottom of the sill and the sash. This can lead to moisture leaking in, rotting of the wood and the growth of mould. Seal the gaps with silicone, polyurethane or foam sealant.
Installing a new sash runner, or spring bronze may be necessary if a gap prevents the windows from closing and opening easily. These bronze strips are tied or stapled to the lower sash edges in order to prevent sideways rattling. They can be purchased at DIY stores. Tubular vinyl weather-stripping is another option however it is prone to rip, and it can make a difference to the appearance of a window.
When replacing sash runners it is essential to measure 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 sash down to the sill. These measurements can be transferred to new runners, which will ensure a better fit and operation of the window.
In older buildings, the gap between sash and frame is usually larger around the leading edge. It can be draught-proofed by using strips of V-strip that is self-adhesive. However, it is important to consider this when measuring and cutting the material.
The strip should be cut at the top of the sash, with an inch added on each side 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 as brass will rust. Also, make sure to use high-quality polyurethane or silicone glue.
Refurbishment

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 put in 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 frame that was previously used and keep the style of your home's historic design. This is particularly important for listed buildings where any changes to the windows require planning permission.

When a window is damaged it's essential to choose between replacement or repair, because each type of work will require a different level of expertise and cost.

Remove the chains or cords that are on both sides. Finally, disconnect the sash weights from bottom of the weight cavity and take them off. Keep the hardware in a safe place. Use a heat gun to soften the old, hardened filler or putty. Scrape it off with the blade of a putty. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray.

It is a massive iron or lead cylinder, which is tucked away in a cavity, and supported by cords. To prevent the sash falling into the void, you must pierce it using a nail, and then sacrifice the weight.
