Sealing

Sash windows are beautiful in older structures, but they require maintenance. They are susceptible to issues such as wet-rot, cracked putty, and draughts. It is possible to decrease energy loss and improve the efficiency of windows with sash by replacing them or repairing them, or sealing them.

Draughts are mostly caused by gaps between the sash and the frame. They can also lead to noise reduction and rattling. Sealing beads, specialty products, and secondary glazing may all be used to minimize the air leakage within a shutter.

A common problem is a gap that exists between the top of the sash and the jamb frame, or between the bottom of sill and the sash. This can lead to moisture leaking in, rotting wood and the growth of mold. Seal the gaps with silicone, polyurethane or foam sealant.

If a gap in the window is preventing the windows from opening and closing without a hitch, it might be necessary to put in new spring bronze or sash runners. These bronze strips are tied or stapled to the lower sash edges in order to prevent the rattling of the sides. They can be bought at DIY stores. Weatherstripping made of tubular vinyl can also be used, however it tends to rip and can detract the appearance of your window.

When replacing sash runners, it is important to measure the entire width of the window opening. It is recommended to take measurements from the top of the sash up to the horizontal centerline of the rail that connects them and from the bottom of sash down to the sill. These measurements can later be transferred to new runners that will ensure a better fit and operation of the window.

In older structures there is a larger gap between the sash and frame around the leading edge. It can be draught-proofed by using a self-adhesive V-strips, but it is crucial to take this into consideration when measuring and cutting the material.

A piece of material should be cut to the length of the sash, with an additional inch on each side to allow movement. It should be trimmed squarely and placed in accordance with the angle of the sill. It is also crucial to use stainless steel screws, because brass is prone to rust, and the best quality polyurethane or silicone adhesive.

Refurbishment

Refurbishment involves lining both the meeting rail and the sash box using traditional putty, and repairing any damage caused by decay. Re-painting of the timber frame 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).

If a window is damaged, it's essential to choose between repair or replacement because each type of work will require a different degree of expertise and expense. If a large portion of the glass in a sash is missing, replacing it would be the better option.

It is crucial to assess the severity of a issue, as it may not be appropriate or even feasible to replace a complete window. For instance, a fogging glass issue is usually a problem within the sash itself and is typically a solution without tearing out the entire frame. A leaky seal can be fixed by making a few minor adjustments rather than an expensive full-frame tear-out and replacement.
