Maintaining Your Sash And Case Windows

| Sash & Case Windows Edinburgh

Timber built sash and case windows are a beautifully crafted item that can provide you with decades of use, but only when they are readily maintained and repaired.

Given sensible maintenance at regular intervals, sash and case windows should remain in excellent condition and will be capable of providing an efficient and continuing climate and bill reducing service.

Cleaning Your Windows

Regular cleaning of the glass and its supporting timber surfaces will also improve the appearance of sash windows and ensure they function smoothly and correctly. We hasten to add, that it is important to be aware of your own safety when cleaning your windows. Keeping both feet firmly on the ground (avoid chairs or stools) and never over-reach. Having the right equipment to do the job is a must.


The upper sash should be drawn down to a comfortable height – it will then be easy to clean the inner face. The outer face should be cleaned with extreme care – bearing in mind the guidelines given below. The lower sashes of many traditional sash and case windows are fitted with the ‘Simplex’ hinge system. If this is the case, then both the inner and outer faces of the sash can be cleaned from within your property. If these hinges are not fitted, you should consider installing Simplex hinges to make cleaning easier.

Cleaning your windows also presents an opportunity to inspect them regularly. This will enable you to keep on top of any developing defects so that corrective action can be taken before they move towards more major problems.


If you do find your windows need repair, there straightforward construction of timber sections means that sash and case windows can be repaired readily – even the most dilapidated windows are usually capable of resurrection.

If you live in a period property, most old sash and case windows were manufactured from exceptionally durable heartwood timber, which these days are now difficult to source. It, therefore, makes sense to retain and repair original joinery rather than replacing wholesale with new timber which may be more susceptible to decay.
