Sash windows look gorgeous in old buildings, however they do need maintenance and are susceptible to problems like wet rot, cracked putty and drafts. It is possible to minimize energy loss and increase the efficiency of windows with sash by replacing them or repairing them, or sealing them.

Draughts are mainly caused by gaps between the sash and the frame. They can also trigger noise reduction and rattle. Sealing beads, specialty products and secondary glazing can all be used to reduce the air leakage in a sash.

A common problem is a gap that exists between the top of the sash and the jamb frame or between the bottom of the sill and the sash. This can result in water leaking into the wood the wood, rotting, and mould growth. Seal the gaps with silicone, polyurethane or foam sealant.

Installing new sash runner or spring bronze could be required in the event that a gap blocks windows from opening and shutting smoothly. These are bronze strips that are stapled or nailed into the edges of the lower sash to prevent sideways rattle, and they can be purchased from DIY stores. Tubular vinyl weather-stripping is another option but it is prone to tear and affect the appearance of windows.

When installing replacement sash runners, it is important to take full measurements of the window opening. It is best to take measurements from the top of sash up to the horizontal centerline of the rail of the meeting 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 buildings the gap between the frame and sash is typically larger around the leading edge. It can be draught-proofed by a self-adhesive V-strips, but it is important to account for this when measuring and cutting the material.

A strip must be cut to the height of the sash. There should be an extra inch to allow for movement. It should be trimmed square and placed so that the ends are aligned to the angle of the window sill.

When a window is damaged it is crucial to decide between repair or replacement because each type of work will require a different degree of expertise and price.

Take the chains and cords from both sides. Then, remove the sash weights and the bottom of the weight cavity and remove them. Keep the hardware in a safe position. Use a heat gun to soften hardened filler or putty. Scrape it away with a blade made of putty. Reassemble the window. Reattach the hardware. Lubricate the pulleys with Teflon or silicone spray.

The sash stops must be removed which is a thin vertical strip of wood that holds the sash. Also, remove any hardware that has been painted. Unscrew the sash to reveal the weight balancing, that is a massive iron cylinder or lead that is enclosed inside a hidden compartment and held by rope. To stop the sash falling into the void hit it with a nail and sacrifice the weight.
