In order to tell if your sash windows need restoration, you should inspect them closely for 5 common signs mentioned later in this article. In short, inspect the wood for warping, cracks, or rot to determine if the sash requires any repairs.

What are sash windows, and what problems can they have over time
Sash windows are a traditional style of window composed of two parts; “sashes,” which slide up and down to open and close and a box where the pulley and weight are allocated.
As they age, sash windows can suffer from problems such as sticking, draughts, rotting woodwork, and even rattling in strong winds. If your sash windows are over 25 years old, it is likely they’ll require some repair or restoration.
5 signs that you need to restore your wooden sash windows
1. Visible rot or decay – Rotting or decaying timber is the most obvious sign of wear and tear on your sash windows. This could be caused by water damage, age, general weathering or lack of regular maintenance or repair.
2. Drafts – If you feel drafts coming from around the window frame or between the sashes, this is a sign that your sash windows need additional insulation, such as draught excludes or draught stripes.
3. Difficulty opening and closing – If the window feels heavy or unbalanced when you try to open it, this could be because of the weight of the sashes or an issue with the mechanism. This can usually be resolved with service and realignment of the springs or repairing sash cords.
4. Paint damage – If you spot any chips, cracks, or discolouration in the paint, this may be a sign that your sash windows require repainting or potentially a full restoration.
5. Broken or missing components – Damaged components like rotten glazing bars or cracked glass should be replaced as soon as possible. Also, check for any missing hardware, such as handles or locks and replace them if necessary.
If you notice any of these five signs, it’s a good indication that your sash window needs restoration.Contact a professional sash windows restoration specialist to get an expert opinion on the best action plan.
