Sealing

Sash windows look stunning in older buildings, however they require maintenance. They can be affected by problems like wet-rot cracked putty, and draughts. Repair, sealing, or replacement of the windows sash is an effective way to reduce these problems and improve the efficiency of energy.

Draughts are mainly caused by gaps between the sash and frame. They can also trigger noise reduction and rattling. Different methods can be employed to stop air leaks from the sash window, such as sealing beads, specialist products and secondary glazing.

A common issue is a gap between the top of the sash and the jamb frame or the bottom of the sill and the sash. This can cause moisture to leak in, rotting wood, and mold growth. Seal the gap with silicone, polyurethane, or foam sealant.

If a gap is preventing windows from opening and closing smoothly, it may be necessary to install new spring bronze or sash runners. These are a type of bronze that are stapled or nailed onto the edges of the lower sash to stop sideways rattle, and they are available at DIY stores. Tubular vinyl weather-stripping is another option, but it has a tendency to tear and affect the appearance of windows.

When installing replacement sash runners It is crucial to measure 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 sash down to the sill. These measurements can be transferred to the new runners, which will help ensure a good fit and a better performance of the window.

In older structures the gap between frame and sash is typically greater around the leading edge. It is possible to draught proof with a strip of self-adhesive V-strip, but it is crucial to take this into consideration when cutting and measuring the material.

The strip should be cut at the height of the sash, with an inch extra on each side to allow for movement. It should be squarely trimmed and placed to align with the angle of the sill. Use stainless steel screws since brass may be rusty. Also, make sure to use the highest quality polyurethane or silicone glue.

Refurbishment

The windows with sash are a stunning historical feature in many homes. But despite their beauty, these windows are susceptible to a myriad of issues. Draughts, rattling or leaking are typical issues.

Refurbishment involves the lining of 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 well as 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).

If a window is damaged, it's essential to choose between replacement or repair, since each kind of repair will involve a different level of expertise and expense. If a large part of the glass in the sash is missing replacing it would be the better option. If the glass is only damaged in a small region or a sill is rotting or rotting, then a repair could be more appropriate.
