Sash Windows Repair and Replacement

Sash windows that are older than 20 years old can be afflicted with many issues, including draughts and rattles. They may also be poorly constructed to be insulated. With a little attention they can be restored to their original performance.

First, remove the seal of paint from the window stop with a utility knife. Then, take off the staff bead, then remove the upper sash, taking off chains or cords, and then storing the hardware in a labeled bag.

Sealing

Sash windows can look stunning in older buildings, but they require maintenance and are susceptible to issues like wet rot, cracked putty, and drafts. Repair, sealing, or replacement of the sash window is an effective method to minimize these issues and improve the efficiency of energy.

The gaps between sash frame are the primary source of drafts. They can also trigger noise reduction and rattling. Different methods can be employed to limit air leaks within windows with sash, including sealing beads, specialty products, and secondary glazing.

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

If a gap is hindering windows from closing and opening without a hitch, it might be necessary to install new spring bronze or sash runners. These are a type of bronze that are stapled or nailed to the edges of the lower sash to prevent sideways rattle. They can be purchased at DIY stores. Weatherstripping made of tubular vinyl can also be used, but it is more likely to tear and can detract the appearance of your window.

It is essential to determine the size of the window opening prior to installing the an alternative sash runner. It is best to take measurements from the top of sash up to the horizontal centerline of the meeting rail and from the bottom of sash down to the sill. These measurements can be transferred to new runners, which will ensure an improved fit and performance of the window.

In older structures there is a larger gap between the sash and frame on the leading edge. It can be draught proofed by a self-adhesive V-strip, but it is essential to take this into consideration when cutting and measuring the material.

The strip should be cut at the top of the sash and with an inch extra on each side to allow movement. The strip should be cut square and placed in a way that the ends are matched to the angle of the window sill. It is also essential to use stainless steel screws, because brass is prone to rust, and high-quality polyurethane or silicone adhesive.

Refurbishment
