Sash Windows Repair and Replacement

Sealing

Sash windows are beautiful in old buildings but they do need maintenance and are susceptible to issues like cracks in putty, wet rot and draughts. It is possible to minimize energy loss and improve the efficiency of sash windows by replacing the windows, repairing or sealing them.

Draughts are mostly caused by gaps between the sash and the frame. They can also trigger noise and rattling, which can reduce soundproofing. Sealing beads, special products and secondary glazing can all be used to reduce the air leakage within the sash.

A common issue is a gap between the top of the sash and the jamb frame or between the bottom of sill and the sash. This can lead to moisture leaking in, rotting wood, and mold growth. Seal the gap using silicone, polyurethane or foam sealant.

Installing a new sash runner or spring bronze may be necessary in the event that a gap blocks windows from opening and shutting effortlessly. These bronze strips are attached by staples or nails to the lower sash edges in order to prevent sideways rattling. They can be purchased at DIY stores. Tubular vinyl weather-stripping is an alternative option but it can rip, and it can detract from the appearance of a window.

It is essential to determine the size of the window opening prior to installing a new sash runners. It is best to take measurements from the top of the sash up to the horizontal centerline of the rails that meet, and from the bottom of the sash down to the sill. These measurements can be transferred to the new runners, which will help ensure a perfect fit and a better performance of the window.

In older structures, the gap between frame and sash is typically wider around the leading edge. It can be draught-proofed by using a strip of V-strip that is self-adhesive. However, it is important to take this into consideration when cutting and measuring material.

The strip should be cut to the height of the sash with an inch extra on each side to allow movement. It should be trimmed squarely and positioned to align with the angle of the sill. It is also crucial to use stainless steel screws because brass is prone to rust, and high-quality silicone or polyurethane adhesive.

Refurbishment

The windows with sash are a stunning historical feature in many homes. These windows are beautiful, but they can be susceptible to issues. Draughts, rattling, sticking or leaks are all common problems. The rotting of frames and meeting rails, broken glass bars or weights that are not working properly can create a mess.

If a window is damaged, it is essential to decide between replacement or repair, because each type of work will require a different degree of expertise and expense. If a large part of the glass in the sash is missing replacing it would be the better alternative. However in the event that the glass is damaged in a small area or a sill is decaying, a repair may be the better option.

It is usually possible to fix a poor seal using a couple of simple fixes, rather than tearing out the entire frame and replacing it.
