Sash Windows Repair and Replacement Sash windows that are older than 20 years old can be afflicted with a variety of problems such as rattles and draughts. They may also be poorly constructed to be insulated. With a little care they can be restored to a higher level of performance.

They can be affected by problems like wet-rot cracked putty, and draughts. Sealing, replacement or repair of the windows in sash is a great method to minimize these issues and increase energy efficiency. The gaps between sash frame are the primary source of drafts. They can also trigger noise reduction and rattle. 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 frequent. This can lead to moisture leaking into the wood, which can cause rotting, and mold 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 required in the event that a gap blocks the windows from closing and opening easily. These are a type of bronze that are stapled or nailed into the edges of the lower sash to stop sideways rattle. They are available from DIY stores.

When installing replacement runners for sash It is crucial to measure the window opening. It is recommended to take measurements from the top of the sash up to the horizontal centerline of the rail that connects them and from the bottom of sash down to the sill. These measurements can later be transferred to new runners that will ensure an improved fit and performance of the window. In older structures the gap between the frames and sash is typically greater around the leading edge. It is possible to draught proof with a strip of self-adhesive V-strip, but it is crucial to consider this when cutting and measuring the material. The strip should be cut at the top of the sash, with an inch extra on each side to allow movement. It should be squarely trimmed and placed in accordance with the angle of the sill. It is also crucial to make use of stainless steel screws since brass can rust and high-quality polyurethane or silicone adhesive.

This will help preserve the traditional style of your house. This is particularly important for listed buildings where any changes to the windows will require planning permission.

If the tabs are different shapes, the new sash will not fit properly into the slots of the window frame. It is important to decide if you want to replace or repair the damaged window, since each choice will require a different degree and amount of knowledge.
