Draughts are mostly caused by gaps between the sash and the frame. They can also trigger rattling and reduced sound-proofing. Sealing beads, specialist products, and secondary glazing can all be used to minimize the air leakage in a sash.
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 the growth of mold. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.
Installing new sash runner or spring bronze might be necessary in the event that a gap blocks the windows from opening and shutting effortlessly. These strips of bronze are attached by staples or nails to the sash's lower edges to stop sideways rattling. They can be bought at DIY stores. Tubular weatherstripping also can be used, however it is more likely to tear and can alter the appearance of your window.

These measurements can be incorporated into the new runners, which will help ensure a proper fit and a better performance of the window.
In older buildings there is a larger gap between the sash and the frame on the leading edge. It can be draught-proofed by using a self-adhesive Vstrip, however it is crucial to account for this when cutting and measuring the material.
The strip should be cut at the top of the sash and with an inch added on each side to allow movement. It should be trimmed squarely and placed to match the angle of the sill.

It involves re-lining the meeting rail and sash boxes with traditional putty and fixing any damage caused by rot. Re-painting the frame of the timber is also included, as is 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). In addition, it is recommended to fit brush pile weather strips to reduce rattling and improve insulation.
If a replacement sash is required, it can be made using the same design to match your old frame. This will maintain the heritage style of your property. This is particularly crucial for listed homes where any changes made to the windows will require planning permission.

If a window has been damaged, it is essential to decide between repair or replacement, because each type of work will involve a different level of expertise and expense. If a large part of the glass in a sash is missing, replacing it would be an alternative.

It's important to consider the severity of the issue, since it might not be practical to replace an entire window. For example, a foggy glass issue usually occurs within the sash itself and is typically a solution without tearing out the entire frame. It is often possible to repair a weak seal with a few simple fixes, rather than tearing out the entire frame and reinstalling it.

Then take the sashweights out of the bottom cavity of the weight. Keep the hardware in a safe location. Heat gun to soften hardened filler or putty.

Adam shows Jess the basics:
The process of bringing the window apart begins by removing any security fittings in front of the lower sash. Then, remove the staff bead, then pull out the bottom sash. Then, remove the cords or chains on both sides and tie the ends to stop them from being pulled back into the frame by the attached weights. It's time to take off the upper sash. Unscrew the sash stoppers (a thin vertical strip of wood that holds the sash) and loosen any painted-covered hardware. The sash can be pulled back to reveal the balancing weight, which is a large iron cylinder that is encased in a hidden cavity and held by rope. To keep the sash from falling into the void hit it with nails and remove the weight.

Then, using a utility blade take off any paint that is on the sash stop. Reattach the stops after the sashes have been put back in place. Use nails that are small enough not to puncture the weight of the balancing.
