Sealing
Sash windows look stunning in older structures, but they require care. They can be affected by issues like wet-rot, cracked putty and draughts. Repair, sealing, or replacement of the windows in sash is a great method to minimize these issues and improve the efficiency of energy.
The gaps between sash frame are the main source of draughts. They can also trigger rattles and reduce sound-proofing. Various methods can be used to stop air leaks from a sash window, including sealing beads, specialist products, and secondary glazing.
A common problem 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 could cause moisture to leak in, rotting wood and 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 could be necessary in the event that a gap blocks the windows from closing and opening easily. These bronze strips are attached by staples or nails to the lower sash edges in order to prevent 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.
When replacing sash runners It is crucial to measure the entire width of the window opening. It is recommended to measure from the top of sash up to the horizontal line on the rail that connects them and from the bottom sash down to the sill. These measurements can later be transferred to new runners, which will ensure a better fit and operation of the window.
In older buildings the gap between frames and sash is typically wider around the leading edge. It can be draught-proofed using a strip of V-strip which is self-adhesive. However it is crucial to consider this when measuring and cutting the material.
The strip should be cut at the height of the sash and with an inch extra on each side to allow for movement. It should be trimmed squarely and placed to align with the angle of the sill. Make sure to use stainless steel screws since brass may be rusty. Also, make sure to use the highest quality silicone or polyurethane glue.
Refurbishment
The sash is an attractive historical feature of a lot of homes. These windows are gorgeous but they can also be prone to problems. Draughts, rattling, sticking or leaking are typical issues. The rotted frames and the meeting rails as and broken glazing bars, faulty frames, or rotten weights can all cause problems. When these issues arise, it's time to consider a sash repair or replacement.

Refurbishment involves the lining of the meeting rail as well as the sash box with traditional putty and fixing any damage caused by decay. It also includes re-painting the frame of timber and re-glazing with 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 strips to reduce rattle and increase insulation.
If a new sash is needed It can be made with the same design to match your existing frame. This will maintain the heritage style of your house. This is particularly important for buildings that are listed, as any changes to the windows will require planning permission.
Before putting the new window in before installing it, make sure you check the metal tabs against those on the old sash (see below). If they're different shapes and sizes, the new sash will not fit into the slots of the window frame.
If a window is damaged, it is crucial to decide between repair or replacement, because each type of work will involve a different level of expertise and cost. If a large portion of the glass in a sash is missing, replacing it would be the better option. If the glass is only damaged in a tiny area or a sill is beginning to rot, then a repair would be more appropriate.

The process of bringing the window apart begins with the removal of any security fittings that are in front of the lower sash. Then, take off the staff bead. Then, remove the sash at the bottom. Then, take the cords or chains on both sides and tie them to prevent them being pulled back into the frame by the weights that are attached. Now it's time to take out the upper sash. Remove the sash stops which is a thin vertical strip of wood that holds the sash. Also, remove any painted-covered hardware. Pull the sash back to reveal the weight. It is a heavy iron or lead cylinder, which is tucked away in a cavity, and supported by a cord. To prevent the sash from falling into the void pierce it with a nail and sacrifice the weight.
After the sashes have been removed, clean the jambs and meet rails. Remove the glazing bars as well as the sash cords. Then, using a utility blade take off any paint that is on the sash stop. When the sashes are back in place, reattach the stops using nails that are not too large to risk cutting the weight that is balancing.

Reassemble the sash by putting the upper sash on top of its track, followed by the lower sash. Make sure that the sash stops are aligned properly with the frame, and then reattach the beads that separate if required. Reattach the sash chains or cords and install the sash pulleys.
