Sash Windows Repair and Replacement

Older sash windows may be prone to a variety of issues, including draughts rattles and poor insulation. With a little effort they can be repaired to a high level of performance.

First, cut off the seal of paint using an utility knife. Remove the staff bead, then pull out the upper sash, and remove any cords or chains. Keep the hardware in a bag that has an identification label.

Sealing

Sash windows can look stunning in old buildings but they require maintenance and can be subject to issues such as wet rot, cracked putty, and draughts. It is possible to decrease energy loss and improve the efficiency of windows made of sash by replacing, repairing or sealing them.

Draughts are mainly caused by gaps between the sash and frame. They can also trigger noise and rattling, which can reduce soundproofing. Different methods can be employed to reduce air leaks in the sash window, such as sealing beads, special products, and secondary glazing.

A gap between the top or bottom of the sash and the jamb frame is a common problem. This can cause moisture leaking in the wood, rotting and the growth of mould. The gap can be filled by caulking made of silicone or polyurethane or foam sealant.

If a gap is preventing windows from closing and opening smoothly, it may be necessary to put in new sash runners or spring bronze. These bronze strips are tied or stapled to the sash's lower edges to prevent sideways rattling. They are available at DIY stores. Tubular weatherstripping also can be used, however it is prone to tear and can alter the appearance of your window.

When replacing sash runners, it is important 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 line on the rail of the meeting and from the bottom of sash down to the sill. These measurements can then be transferred to new runners that will ensure the best fit and function of the window.

In older buildings there is a greater gap between the sash as well as the frame around the leading edge. It can be draught-proofed by using a strip of V-strip which is self-adhesive. However it is crucial to take this into account when cutting and measuring material.

A strip should be cut to the height of the sash. There should be an additional inch each side to allow for movement. It should be squarely trimmed and positioned in accordance with the angle of the sill. Use stainless steel screws since brass may be rusty. Also, make sure you use the highest quality polyurethane or silicone glue.

Refurbishment

The sash is a beautiful, historical feature of many homes. Yet despite their beauty, windows like sash windows can be prone to a myriad of issues. The most frequent issues are rattling, draughts or sticking. The rotted frames and the meeting rails as well as broken glazing bars, faulty frames, or rotten weights can all cause problems. When these problems occur it's time to consider an sash repair or replacement.

Refurbishment is more expensive alternative than replacing the sash, but it can restore the look and function of your sash window to as good if not superior to its original state. Refurbishment involves the lining of both the meeting rail and the sash box using traditional putty, and then repairing any damage caused by the rot. Re-painting of the timber frame is also included, as is glazing using traditional glass. 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). Finally, it's recommended to put in brush pile weather strips to reduce rattle and increase insulation.

If the need for a new sash arises the frame can be constructed using similar designs to the old frame and maintain your property's heritage style. This is especially important for listed buildings where any changes to the windows need planning permission.

Compare the metal tabs on the new window to the old sash before installing it (see below). If these are different shapes the new sash will not fit properly into the slots of the window frame.

If a window has been damaged, it's essential to choose between repair or replacement because each type of work will involve a different level of expertise and cost. If a significant portion of the glass in the sash is missing replacing it is a better alternative. However in the event that the glass has been damaged in a small area or a sill has been damaged, a repair would be more appropriate.

Replacement

Although many homeowners want to keep their old windows in good condition, deterioration could eventually result in problems like rattles, draughts or even broken glass.

A foggy glass problem, for example is typically caused by the sash, and can be resolved without tearing out the entire frame. It is usually possible to fix a poor seal using a couple of simple solutions, rather than cutting out the entire frame and reinstalling it.
