Sealing

Sash windows are beautiful in older structures, but they require regular maintenance. They are susceptible to problems like wet-rot cracked putty, and draughts.

The gaps between the sash and frame are the main source of draughts. They can also trigger noise reduction and rattle. Various methods can be used to reduce air leaks in the sash window, such as sealing beads, specialist products and secondary glazing.

If a gap is hindering the windows from closing and opening smoothly, it may be necessary to replace spring bronze or sash runners. These are a type of bronze that are stapled or nailed to the edges of the lower sash to stop sideways rattle. They are available at DIY stores. Tubular vinyl weatherstripping can also be used, but it is more likely to tear and may alter the look of your window.

These measurements can be incorporated into the new runners, which will ensure a proper fit and a better performance of the window.

In older structures there is a greater gap between the sash as well as the frame around the leading edge. It is possible to draught proof by a self-adhesive V-strip, but it is important to account for this when measuring and cutting the material.

The strip should be cut to the height of the sash and with an inch added on each side to allow movement. It should be trimmed squarely and placed in accordance with the angle of the sill. Use stainless steel screws as brass may get rusty. Also, use a high quality silicone or polyurethane glue.

Before you put the new window in place, it's best to compare its metal tabs to the tabs on the old sash (see below). If the tabs are different shapes, the new sash will not fit properly into the slots of the window frame.

If a window is damaged, it is essential to decide between repair or replacement because each type of work will require a different level of expertise and expense.
