Here is more information on why you should repair, if at all possible, and not refurbish timber sash and case windows.

It is best to record the defects for each window as it is inspected. This will allow appraisal of the scope of repair works required.  If it appears to be a major fault may turn out to be simply the failure of a protective paint finish. Conversely a recent paint coating may conceal underlying timber decay. A sharp knife can be used to probe through surface finishes, and a damp meter can help to determine the moisture content of vulnerable timbers. (A damp meter must be calibrated before use in order to obtain accurate readings of moisture content, and care should be taken to ensure its sensors are not recording the surface condition of the timber). The thorough inspection of windows will help avoid the costly and disruptive wholesale renewal of basically sound windows, as well as ensuring that a cosmetic “cover-up” with putty and paint is not used to disguise decayed timber or other fundamental defects.

Most sash and case windows can be readily restored. It’s usually possible to restore even the most rundown windows. Most old sash windows were made from highly durable heartwood timber of a quality that’s now difficult to find. It makes sense to keep and repair original wood rather than replacing it wholesale with new wood, which may be more prone to decay.

It’s unlikely that you would carry out repairs to windows yourself. But you should inspect the window carefully before employing a joiner. This will help you to agree on the work required and how much it will cost.
