Maintaining Timber Windows
A well-maintained wooden window is a crucial component of a historical building. It illustrates in varying degrees the various materials and techniques as well as the craftsmanship and architectural style of the period that it was built in.
If repairs are possible to windows that are already in use should be done in-situ. Repair systems made of resin can be used to repair the most deteriorated areas without removing the entire

Durability
Timber windows were made to last for centuries. However, they do need to be maintained to ensure they look great and working correctly. The most frequently-asked maintenance tasks include sash-cord repairs, re-tightening sash pulleys, and painting. There is a growing need to upgrade the timber windows to improve energy efficiency. This can include replacing old glazing units, fixing existing window rebates, or installing new cills to improve air seal.
One of the main issues with traditional windows is the damage caused by corrosion of the paintwork. This is especially important where windows made of sash are involved because the gaps between the sashes can be quite wide. In these circumstances, water can penetrate the paint film and cause rotting of the putty as well as the wood underneath. The weather can be a factor in accelerating the rotting. To stop this from happening, windows need to be painted regularly with an exterior wood paint.
Corroded areas should be repaired using resin-based products. This will ensure that the greatest amount of the original fabric is retained. It is also essential to minimise the number of holes you drill into the frame to allow cable entry as these can allow water in and cause decay.
Another issue with older windows is structural movement in the wall which could cause deformation of the frame and the sash. This can lead to sash no longer fitting correctly and jamming or sticking to the opening and cracked glazing. Often this can be corrected by the fitting of new sash boxes constructed from slow-growing deal (pine) or oak. The cill must be constructed of a durable hardwood like oak to prevent movement between the old and new work.
To reduce the risk, there are now a variety of companies that manufacture Boston pattern wooden sash that will fit into the majority of existing openings. They are available in a variety of sizes and finishes to fit the needs of modern homeowners. Combined with quadruple draught strips and better thermal insulation these new sash can make an enormous difference to the energy efficiency of your home.
Aesthetics

They may also have significant historical value in their individual cases. This is particularly true for early unglazed windows in timber-framed buildings, where the majority of them were series of openings in structural frames subdivided horizontally by mullions, and vertically by iron or wood bars in order to keep out intruders.
Traditional

As soon as you notice any signs of decay caused by the penetration of moisture, it is important to stop it. This can be done by painting thoroughly, especially in areas where there has already been damage or deterioration. It is recommended to use paints that are designed to be used in a set (primer undercoat and finish) and follow the manufacturer's guidelines for preparation and number coats at each stage.
The fungus that causes wet rot is able to spread quickly in old windows made of wood. To prevent this from happening, get rid of any damaged or rotten parts as soon as you can. The replacement of rotting wood should be carefully undertaken using slow grown deal (pine) and, wherever feasible, the same species as which is being removed to prevent differential movement between the new and old timbers.
glass repair cambridge became less expensive and more abundant during the late medieval period and into the 17th century. In the process, glazed openings on timber-framed houses were more elaborate, with moulded mullions, tracery made of wood and deep cills projecting into the air. Increasingly, the glazing was placed within frames with rebates and pinned in with 'glazing sprigs' rather than into lead cames. This method of glazing is not just less susceptible to leaks, but it also allows larger, clearer sheets of glass to be used in the windows than would be possible without the need for lead lights.
Energy efficiency
Traditional timber windows offer an excellent energy performance due to their thickness, multi-layer construction and very careful attention to detailing. They also have large glass areas and projecting cills that reduce air infiltration. With secondary glazing and draughtproofing windows can be made more efficient to improve their energy efficiency. It is important to remember that these measures must be taken into consideration when it comes to the overall integrity and appearance of the original windows.
As a result, retaining existing historic windows that are in need of repair instead of replacing them is sensible especially when their thermal enhancements can be made economically through simple repairs and improvements. Historic windows often have historical significance that demonstrates a range of technological advances and changes in architectural style. Most people assume that these windows will need to be replaced in the near future. However, they can still provide service for 150,200, and even 250 years with proper maintenance.
It is crucial to recognize that the decay issues that are typical of timber windows can be prevented by regular maintenance and swift repairs. It is also essential to identify damp problems and fix them quickly in order to avoid major damage. Paint deterioration that occurs early could be a problem as it allows moisture to get into the wood, which can cause wet rot. This damage is often not evident until the paintwork becomes cracking or wavy however, it can cause serious structural damage and lead to further decay.
A high-quality paint will stop this moisture from entering. To prevent mould and condensation it is crucial to keep the paintwork as clean as possible. Modern synthetic paints pose a problem since they are usually water-resistant, and can cause mildew to develop in the window frame.
The majority of windows from the past were constructed from timber with the majority of sapwood. The timbers will deteriorate quickly when exposed to wet weather conditions, but they can be protected with an extensive preservative treatment prior to when they are used. It is also essential to ensure that the kind of wood used is suited to the site and climate conditions, since these factors will influence the durability of the joinery. Local
window repair manufacturers have a wide range of sash timbers that can be customized to fit historic openings. They can be constructed to the standard Boston pattern dimensions or to custom sizes that are in keeping with the historic architecture.
Maintenance
Regular inspections carefully redecorated, as well as timely repairs can prolong the lifespan of windows made of timber. The main cause of decay is moisture leaking through deteriorated paint or putty. This can be avoided by using a high-quality wood preservative and painting the wood thoroughly.
It is important that repairs to old sash and casement windows are done correctly and completed with the minimum disturbance. It is possible to fix several traditional designs of timber windows without removing the frame. This should be done whenever possible. Remove peeling or loose paint and lightly sand the surface to improve the "key" of the surface. This will enable the new coating to adhere better. It is essential to avoid removing old paint layers, as they may have historical significance.
When a piece of wood has become rotten the best option is to remove the rotted material and replace it with spliced-in timber inserts that are shaped to match the existing profiles. The wood that is inserted should be treated with wood preservative and the connection between the cill for timber and the sub-cill of the masonry should be sealed.
It is tempting to replace traditional windows with PVC u, especially if the installer offers an all-in-one installation that includes both removal and replacement in a single day. It is crucial that installers of replacement windows have a thorough understanding of the history and construction of traditional timber frames. This will enable them to make the appropriate recommendations for energy-efficiency improvements and other technological improvements that don't alter the appearance of a historic building. Anyone who installs replacement windows should be registered with a Competent Persons Scheme, such as FENSA. This will ensure that the replacement windows are approved as a suitable solution in accordance with Building Regulations. It is, of course, possible for a skilled and experienced carpenter to install PVC-U windows that match the style of the building originally. This is especially true when the windows are in listed buildings or conservation areas.
