Sash Windows Repair and Replacement
Sash windows older than 20 years can have various issues such as rattles and draughts. They may also be poorly constructed to be insulated. A little care can often bring them back to their original performance.

Sealing
Sash windows look stunning in older buildings, however they require care. They can be affected by problems like wet-rot cracked putty and draughts. Repair, sealing, or replacement of the windows in sash is a great method to eliminate these issues and improve the efficiency of energy.
Draughts are mainly caused by gaps between the sash and frame. They can also cause rattles and reduce sound-proofing. There are a variety of methods to stop air leaks from windows with sash, including 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. Seal the gap using silicone, polyurethane, or foam sealant.
Installing new sash runner or spring bronze may be required when a gap is preventing the windows from closing and opening smoothly. These are a type of bronze that are stapled or nailed to the edges of the lower sash in order to prevent sideways rattle. They are available at DIY stores. Tubular vinyl weatherstripping can also be used, however it is more likely to tear and can alter the appearance of your window.
When replacing sash runners It is crucial to measure the entire width of the window opening. It is recommended to take measurements from the top of the sash to the horizontal line of the meeting rail 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 good fit and a better performance of the window.
In older structures there is a greater gap between the sash and frame at the leading edge. It is possible to draught-proof it 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 must be cut to the width of the sash, with an extra inch for movement. It should be trimmed squarely and placed to align with the angle of the sill. Make sure to use stainless steel screws since brass may rust. Also, make sure to use high-quality polyurethane or silicone glue.
Refurbishment
The sash is a beautiful, historical feature of many homes. Yet despite window repair , these windows are susceptible to a range of issues. Draughts, rattling, sticking or leaking are common issues. The rotting of frames and connecting rails, broken glazing bars or weights that are not working properly can create a mess. When these problems occur it's time to consider a sash repair or replacement.
Refurbishment is more costly than replacing the sash, but can bring back the appearance and function to the same level in its original condition. Refurbishment involves re-lining both the meeting rail and the sash box with traditional putty, and repairing any damage caused by the rot. Re-painting the frame of the timber 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). It is also recommended to install brush pile weather strips to reduce rattling and improve insulation.
If a replacement sash needed it can be constructed using the same design to match your old frame. This will maintain the heritage style of your home. This is particularly important for listed properties where any modifications made to the windows will require planning permission.
Before you put the new window on before installing it, make sure you check the metal tabs against the tabs on the old sash (see below). If they're different shapes the new sash may not fit in the window frame slots.
It is important to decide if you want to replace or repair windows that are damaged, as each will require a different degree and cost of expertise. If a large part of the glass in the sash is missing then replacing it will be an option. If the glass is only damaged in a small region or a sill has begun to decay and needs to be repaired, then a repair will be better.
Replacement

These include the installation of secondary glazing and draught-proofing.
It is important to determine the extent of a issue, since it might not be appropriate or even practical to replace an entire window. For instance, a fogging glass issue is usually a problem in the sash itself and is usually able to be resolved without tearing out the entire frame. A weak seal can often be remedied with a few simple fixes rather than an expensive full-frame tear-out and replacement.
