Sash windows are gorgeous in older buildings, however they require regular maintenance. They can be affected by issues such as wet-rot, cracked putty and draughts. Repair, sealing or replacement of the windows sash is an effective method to eliminate these issues and increase energy efficiency.

Draughts are mostly caused by gaps between the sash and the frame. They can also cause rattling and reduced sound-proofing. Sealing beads, special products and secondary glazing can be used to limit the air leakage inside the Sash.

A gap between the top or bottom of the sash, and the jamb frame, is an issue that is common. This can cause water leaking into the wood and rotting of the wood and growth of mould. The gap can be closed by caulking made of silicone or polyurethane or foam sealant.

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

The strip should be cut square and positioned so that the ends are matched to the angle of the window sill. Use stainless steel screws as brass may get rusty. Also, make sure you use the highest quality silicone or polyurethane glue.
