Sealing
Sash windows can look stunning in old buildings, however they require maintenance and can be subject to issues such as cracks in putty, wet rot and draughts. Repair, sealing or replacement of the windows in sash is a great way to reduce these problems and improve the efficiency of energy.
The gaps between sash and frame are the primary cause of draughts. They can also cause noise and rattling, which can reduce soundproofing. Sealing beads, special 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 between the bottom of sash and the sill. This can cause moisture leaking in the wood, rotting, and mould growth. The gap can be sealed with silicone or polyurethane caulking or foam sealant.
If a gap is preventing the windows from closing and opening without a hitch, it might be necessary to put in new sash runners or spring bronze. These are a type of bronze that are stapled or nailed to the edges of the lower sash in order to prevent sideways rattle, and they can be purchased from DIY stores. Tubular vinyl weather-stripping is another option but it has a tendency to tear and affect the appearance of windows.
It is important to take measurements of the entire window opening before installing replacement sash runner. It is recommended to take measurements from the top of the sash up to the horizontal centerline on the rail that connects them and from the bottom sash down to the sill. These measurements can be incorporated into the new runners, which will help ensure a proper fit and better operation of the window.
In older structures the gap between sash and frame is usually wider around the leading edge. It is possible to draught-proof it using a strip of V-strip that is self-adhesive. However, it is important to consider this when measuring and cutting the material.
A strip must be cut to the length of the sash, with an extra inch on each side to allow movement. It should be cut square and positioned in a way that the ends are aligned to the angle of the window sill. Make sure to use stainless steel screws since brass may get rusty. Also, make sure you use the highest quality silicone or polyurethane glue.
Refurbishment

Re-painting of the timber frame is also included, as well as the re-glazing process 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). It is also recommended to install brush pile weather strip to reduce the noise of rattling.

Remove the cords or chains on both sides. Finally remove the sashweights from the bottom cavity of the weight. Place the hardware in a safe location. The heat gun will soften the old, hardened filler or putty. Scrape it off using a putty blade. Reassemble the window, reattach the hardware and lubricate pulley axles using silicone or Teflon spray.

Remove any security fittings that are in front of the lower window sash. Then, remove the staff bead, then pull out the bottom sash. Remove the cords and chains from both sides, and tie them in a way that they can't be pulled back by the weights. The next step is to take out the upper sash. Remove the sash stops and a thin wood strip that holds the sash. Also, remove any hardware that has been painted. Unscrew the sash to reveal the weight balancing, which is a heavy lead or iron cylinder enclosed inside a hidden compartment and held by a rope. To stop the sash from falling into the void pierce it using a nail, and sacrifice the weight.
After the sashes have been removed, clean the jambs and the rails that meet. Remove the glazing bars and cords of the sash. Then, using a utility blade take off any paint from the sash stop. Once the sashes are back in place, you can reattach the stops using nails that are not too large to risk damaging the balancing weight.
Reassemble the sash by placing the upper sash on top of its track, then the lower sash. Make sure that the sash stops and the frame are aligned properly. If needed, reconnect any beads used for parting. Finally, reattach the sash cords or chains and re-install the axles of the sash pulleys.
