Sash Windows Repair and Replacement

Sash windows older than 20 years old can be afflicted with many issues, including draughts and rattles. They could also be inefficiently insulated. A little bit of care can often bring them back to their original performance.

Sealing

Sash windows are gorgeous in older buildings, but they require care. They are susceptible to problems like wet-rot cracked putty, and draughts. It is possible to decrease energy loss and increase the efficiency of sash windows by replacing, repairing or sealing them.

The gaps between the sash and Window Doctor frame are the main source of drafts. They can also trigger rattles and reduce sound-proofing. There are a variety of methods to limit air leaks within windows with sash, including sealing beads, specialist products and secondary double glazing.

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

Installing new sash runner or spring bronze may be required in the event that a gap blocks the windows from opening and shutting easily. These strips of bronze are stapled or nailed to the lower sash edges in order to stop the rattling of the sides. They can be purchased at DIY stores. Tubular vinyl weather-stripping is an alternative option, but it can tear, and can detract from the appearance of windows.

When installing replacement 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 centerline 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 that will ensure the best fit and function of the Window Doctor.

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

The strip should be cut at the height of the sash and 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. Use stainless steel screws since brass can get rusty. Also, make sure to use high-quality silicone or polyurethane glue.

Refurbishment

Replacement
