The gaps between the sash and frame are the main source of draughts. They can also lead to rattling and reduced sound-proofing. Sealing beads, specialist products and secondary glazing can be used to limit the air leakage in the Sash.
A gap between the top or bottom of the sash, and the jamb frame, is a common problem. This can lead to the leaking of moisture and rotting of the wood and the growth of mould. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.
Installing a new sash runner, or spring bronze might be necessary in the event that a gap blocks windows from opening and shutting easily. These strips of bronze are stapled or nailed to the lower sash edges in order to stop sideways rattling. They can be purchased at DIY stores. Tubular weather-stripping made of vinyl is a different option, but it is prone to tear and affect the appearance of a window.
When installing replacement runners for sash it is essential to measure the window opening. It is recommended to take measurements from the top of sash up to the horizontal centerline on the meeting rail and from the bottom sash down to the sill. These measurements can be transferred to new runners, which will ensure an improved fit and performance of the window.
In older buildings there is a greater gap between the sash as well as the frame on the leading edge. It can be draught-proofed by using a self-adhesive V-strip, but it is crucial to account for this when measuring and cutting the material.
A piece of material should be cut to the height of the sash. There should be an extra inch to allow movement. It should be trimmed squarely and positioned to match the angle of the sill. It is also crucial to use stainless steel screws, since brass can rust and high-quality polyurethane or silicone adhesive.
Refurbishment

To start a repair project take out the window stops (the moldings that are in front of the lower sash). Then, loosen the staff bead and pull out the lower sash. Remove the chains and cords from both sides. Finally remove the sashweights from the bottom of the cavity for weight. Keep the hardware in a secure location. Heat gun to soften hardened filler or putty. Scrape it away with a blade made of putty. Reassemble the window, reconnect the hardware and lubricate pulley axles with silicone or Teflon spray.

Remove the sash stops and a thin strip of wood that holds the sash. Also, take off any paint-encrusted hardware. Unscrew the sash to reveal the balancing weight which is a large iron cylinder or lead that is enclosed in a hidden cavity and secured by rope. To stop the sash from falling into the void pierce it using a nail, and then let the weight go.
When the sashes are untied clean the jamb and meet rails. remove the glazing bars and sash cords and scrape off any paint off the sash stops using the help of a utility knife. Reattach the stops after the sashes are reinstalled. Use nails that are small enough not to puncture the balancing weight.
Reassemble the sash by inserting the upper sash first on its track, then the lower sash. Make sure that the sash stops and the frame are aligned correctly. If needed, reconnect any parting beads. Then, reconnect the sash chains or cords and re-attach the sash pulley axles.
