Sealing

Sash windows are beautiful in older buildings, however they require care. They can be affected by issues like wet-rot, cracked putty, and draughts. Repair, sealing or replacement of the windows in sash is a great method to eliminate these issues and improve the efficiency of energy.

Draughts are mostly caused by gaps between the sash and the frame. They can also lead to noise reduction and rattle. Sealing beads, special products and secondary glazing can be used to limit the air leakage in the Sash.

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

If a gap is preventing the windows from closing and opening easily, it could be necessary to put in new spring bronze or sash runners. These bronze strips are stapled or nailed to the lower sash edges to prevent the rattling of the sides. They can be purchased at DIY stores. Weatherstripping made of tubular vinyl can also be used, however it is prone to tear and can alter the appearance of your window.

When replacing sash runners it is essential to measure the entire width of the window opening. It is best to take measurements from the top of the sash up to the horizontal line on the rail that connects them and from the bottom of sash down to the sill. These measurements can later be transferred to new runners which will ensure the best fit and function of the window.

In older structures the gap between sash and frame is usually wider around the leading edge. It is possible to draught proof with a strip of self-adhesive V-strips, but it is crucial to consider this when cutting and measuring 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 square and positioned in a way that the ends are aligned to the angle of the window sill. It is also important to use stainless steel screws since brass can rust and high-quality polyurethane or silicone adhesive.

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). It is also recommended to install brush pile weather strip to reduce rattling.

Before putting the new window in, it's best to check the metal tabs against the tabs on the old sash (see below). If they're different shapes, the new sash will not fit properly into the slots of the window frame.

If a window is damaged, it is crucial to decide between replacement or repair, because each type of work will require a different degree of expertise and expense. If a significant portion of the glass in a sash is missing replacing it is a better alternative. If the glass is damaged in a small area or a sill is beginning to rot, then a repair would be better.
