Sealing

Sash windows can look stunning in older buildings, but they require regular maintenance and can be subject to problems like cracks in putty, wet rot, and draughts. Repair, sealing, or replacement of the sash window is an effective way to reduce these problems and improve energy efficiency.

Draughts are mainly caused by gaps between the sash and frame. They can also trigger noise reduction and rattle. Various methods can be used to stop air leaks from a sash window, including sealing beads, special products, and secondary glazing.

A common problem is a gap between the top of the sash and the jamb frame, or between the bottom of the sill and the sash. This could cause moisture to leak in, rotting wood, and mold growth. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.

If a gap is hindering the windows from opening and closing easily, it could be necessary to install new sash runners or spring bronze. These are bronze strips that are stapled or nailed to the edges of the lower sash in order to prevent sideways rattle. They can be purchased from DIY stores. Tubular weatherstripping also can be used, but it is prone to tear and can detract the appearance of your window.

These measurements can be transferred to new runners that will ensure the best fit and function of the window.

In older buildings the gap between sash and frame is usually greater around the leading edge. It can be draught-proofed with a strip of self-adhesive Vstrip, however it is essential to take this into consideration when cutting and measuring the material.

A piece of material should be cut to the width of the sash, and with an extra inch each side to allow for movement. The strip should be cut square and positioned so that the ends are aligned to the angle of the window sill. Make sure to use stainless steel screws since brass may get rusty. Also, use the highest quality polyurethane or silicone glue.

Refurbishment
