Timber windows were built to last for centuries. But, they have to be maintained to ensure they look good and functioning correctly. The most frequently-asked maintenance tasks include sash-cord repairs as well as tightening sash pulleys and painting.

This may mean replacing old glazing units, repairing existing window repairs cambridge rebates or putting in new cills that allow for better air sealing.

The deterioration of paintwork is a major problem with traditional windows. This is particularly true when sash windows are involved as the gaps between sashes can be extremely wide. In these instances water can enter the paint film and cause rotting to the wood or putty underneath. The rotting can be exacerbated due to weather conditions that are poor.

It is also important to limit the number of holes you drill into the frame to allow cable entry since these could let in water and cause decay.

Another major issue with older windows is the structural movement within the wall which can lead to deformation of the frame and sash. This can lead to sash no longer fitting correctly or sticking or jamming into the opening, and damaged glazing.

The fungus that causes wet rot can spread quickly in old timber windows. To prevent this, take out any damaged or rotten parts as quickly as you can. The replacement of wood that is rotting should be carefully undertaken using slow grown deal (pine) and, wherever possible using the same species as that which is being removed to prevent any movement differences between the new section and existing timbers.

Glass became cheaper and more abundant during the late medieval period and into the 17th century. As a result, the glazed openings in timber-framed homes became more complicated with moulded mullions, wooden tracery and deep cills projecting into the air. Increasingly, the glazing was placed within frames with rebates and then pinned by 'glazing sprigs' rather than being inserted into lead cames. This method of glazing is not only less prone to leaks but also allows for more expansive and clearer sheets of glass to be used in the windows than would otherwise be possible without the need for lead lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness and multilayer construction, as well as their care for detail. They also have large glass areas and deep projecting cills that reduce air infiltration. Windows can be designed to improve their energy efficiency by draught-proofing and secondary double glazing near me. It is important to remember that these measures should be taken into consideration when it comes to the overall integrity and appearance of the original windows.

It is logical to fix or upgrade windows, rather than replacing them, especially when the improvement in energy efficiency can be made through simple repairs. Historic windows are often of historical significance, since they show a range in technological advancement and changes in architectural style. Most people think that these windows will have to be replaced in the near future. However, many of them will last for 150,200, and even 250 years with proper maintenance.
