Sealing
Sash windows look gorgeous in old buildings but they require regular maintenance and can be subject to issues like wet rot, cracked putty and drafts. It is possible to reduce energy loss and increase the efficiency of windows made of sash by replacing or repairing them, or sealing them.
Draughts are usually caused by gaps between the sash and the frame. They can also cause noise and rattling, which can reduce soundproofing. Sealing beads, specialist products and secondary glazing can all be used to minimize the air leakage within a shutter.
A gap between the top and bottom of the sash, and the jamb frame is an issue that is frequent. This can lead to moisture leaking into the wood, which can cause rotting, and mold growth. Seal the gap with silicone, polyurethane or foam sealant.
Installing a new sash runner or spring bronze could be required in the event that a gap blocks windows from opening and shutting easily.

A strip should be cut to the width of the sash, with an extra inch on each side to allow movement. It should be squarely trimmed and positioned to align with the angle of the sill. Use stainless steel screws since brass will get rusty. Also, make sure you use a high quality polyurethane or silicone glue.
Refurbishment

Re-painting the frame of the timber is also included, as well as re-glazing 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 important to determine the extent of a issue, since it might not be appropriate or even practical to replace an entire window. A glass that is foggy for instance is typically caused by the sash and can be resolved without tearing out the entire frame. It is often possible to fix a weak seal by making a few easy fixes, rather than tearing out the entire frame and replacing it.

Finally, remove the sash weights from bottom of the cavity and remove them. Keep the hardware in a secure location. Use a heat gun to soften hardened filler or putty. Scrape it away with a blade made of putty. Reassemble the window, attach the hardware and then lubricate the pulley axles by using silicone or Teflon spray.

Remove the sash stops and a thin wood strip that holds the sash. Also, take off any paint-encrusted hardware. Pull the sash back to reveal the weight. It is a massive iron or lead cylinder, which is tucked away in a cavity, and supported by an elastic cord. To stop the sash from falling into the void pierce it with a nail and sacrifice the weight.
When the sashes are untied clean the jamb and meet rails. remove the glazing cords and sash bars, and strip any paint off the sash stops with a utility knife. After the sashes have been put returned to their original positions, you can attach the stops using nails that are small enough to prevent damaging the weight that is balancing.
