Sealing

Sash windows are beautiful in old buildings, however they require regular maintenance and could be susceptible to issues such as wet rot, cracked putty and drafts. It is possible to minimize energy loss and improve the efficiency of sash windows by replacing or repairing them, or sealing them.

Draughts are usually caused by gaps between the sash and the frame. They can also lead to noise reduction and rattling. Various methods can be used to reduce air leaks in a sash window, including sealing beads, specialist products, and secondary glazing.

Installing a new sash runner, or spring bronze might be required in the event that a gap blocks windows from closing and opening effortlessly. These are strips of bronze that are stapled or nailed to the edges of the lower sash in order to prevent sideways rattle, and they can be purchased at DIY stores. Tubular vinyl weather-stripping is an alternative option, but it has a tendency to tear, and can affect the appearance of windows.
