Sealing

Sash windows are beautiful in older buildings, but they require maintenance and can be subject to issues such as cracks in putty, wet rot, and drafts. Sealing, replacement or repair of the sash window is an effective method to minimize these issues and improve energy efficiency.

Draughts are mainly caused by gaps between the sash and the frame. They can also cause noise and rattling, which can reduce soundproofing. Sealing beads, specialty products and secondary glazing can be used to limit the air leakage in the shutter.

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

Installing a new sash runner or spring bronze may be necessary when a gap is preventing the windows from closing and opening easily. These are strips of bronze that are stapled or nailed to the edges of the lower sash to stop sideways rattle, and they are available at DIY stores. Tubular vinyl weather-stripping is an alternative option but it is prone to rip, and it can detract from the appearance of windows.

It is important to measure the entire window opening before installing an alternative sash runner. It is best to take measurements from the top of the sash up to the horizontal line on the meeting rail and from the bottom sash down to the sill. These measurements can be incorporated into the new runners, which will ensure a proper fitting and better operation of the window.

In older structures there is a larger gap between the sash as well as the frame around the leading edge. It is possible to draught-proof it using a strip of V-strip that is self-adhesive. However it is essential to consider this when measuring and cutting material.

The strip should be cut to the height of the sash with an inch more on each side to allow for movement. It should be cut squarely and positioned in accordance with the angle of the sill. Use stainless steel screws as brass can rust. Also, make sure to use high-quality polyurethane or silicone glue.

Refurbishment

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's also recommended to install brush pile weather strip to prevent rattling.

If you require a new sash it can be constructed from similar designs to the frame that was previously used and keep the style of your home's historic design. This is especially important for listed properties where any changes made to windows will require planning permission.

It is crucial to determine whether to replace or repair a damaged window, as each option will require a different degree and amount of expertise. For instance when a sash window has a large piece of glass that is missing, then replacing it is the best option.

Remove the sash stops (a thin vertical strip of wood that is used to hold the sash) and remove any painted-covered hardware. The sash should be pulled back to reveal the weight. It is a large iron or lead cylinder that is concealed inside a cavity and held by a cord. To prevent the sash falling into the void pierce it using a nail, and then let the weight go.
