Maintaining Timber Windows

A well-maintained and maintained timber window repairs near me is a crucial element of the historic fabric of a building. It is a representation of the materials and technologies as well as the craftsmanship and architectural style of the time period that it was built in.

When repairs are feasible to Upvc Windows cambridge that are already in use should be done in situ. Repairing the most severe areas of decay is possible using proprietary resin-based systems.

Durability

Timber windows were made to last hundreds of years. They do require some maintenance to keep them looking good. Maintenance tasks include repairs to sash cables as well as tightening the pulleys on sash, and painting. There is a growing need to upgrade timber windows to increase energy efficiency. This may include replacing old glazing units, fixing existing upvc window and door repairs rebates or installing new cills to improve air seal.

One of the major issues with traditional windows is the damage caused by the corrosion of the paintwork. This is particularly true when sash windows are involved as the gaps between the sashes can be very large. In these cases, water can penetrate paint film and cause rotting to the wood or putty underneath. Weather conditions that are not ideal can accelerate the rotting. To prevent this windows, they should be painted regularly with an exterior wood paint that is suitable.

Areas that have been damaged must also be repaired using a resin-based product. This will ensure that the maximum possible amount of the original fabric is preserved. It is also essential to minimise the number of holes drilled into the frame for cable entry since these could admit water and lead to decay.

The wall's structural movement can also lead to distortions in the frame as well as the sash. This can lead to sash no longer fitting correctly and jamming or sticking to the opening, and damaged glazing. Most often, this is corrected by fitting new sash boxes made from slow grown deal (pine) or oak. The cill should be constructed from a sturdy hardwood, like oak, to prevent differential movement between new and old work.

There are several companies that produce Boston pattern wooden sash to fit in with the majority of openings. These sash come in a variety of sizes and finishes to meet the requirements of modern-day homeowners. The new sash, combined with quadruple draft strips and improved thermal insulation can make a significant difference to the efficiency of your home's energy usage.

Aesthetics

Many old timber windows have a high aesthetic value because they typically demonstrate, in a way the materials and techniques and architectural style of the period from when they were built. They also may have significant historical value in their in their own right. This is particularly true of early windows that were not glazed in timber-framed buildings, where the majority were series of openings within frames of structural construction, which were divided horizontally by mullions with vertical wood or iron bars to keep out invaders.

Traditional window joinery made from timber can be a highly decorative aspect of a building, and is essential to keep its appearance. As soon as you notice any signs of decay caused by moisture penetration it is crucial to stop it. It is recommended to do this with thorough painting, especially if there has been damage or deterioration. It is recommended to use paints that are specifically designed to be used as part of the system (primer, undercoat and finish) and to follow the manufacturer's recommendations in terms of preparation and the amount of coats required at each stage.

The fungus responsible for wet rot is able to spread quickly in old timber windows. To prevent this from happening, remove any rotten or damaged parts as promptly as you are able to. The replacement of rotting timber should be done with care and by using a slow-growing deal (pine) and, if possible using the same species as which is being removed to prevent differential movement between the new section and the existing timbers.

Glass became cheaper and more abundant in the late medieval period and into the 17th century. In the process, the glazed openings in timber-framed homes became more complex with moulded mullions, tracery made of wood and cills that protruded deep. In the past, more often, the glass was laid within rebated frames and then pinned with 'glazing sprigs' rather than being inserted into lead cames. This method of glazing not only makes the windows less likely to leak, but also allows for more clear glass sheets to be utilized than would have been possible without the use of lead lights.

Energy efficiency

The traditional timber windows are energy efficient because of their thickness, multilayer construction and focus on detail. The large glass areas, the deep projection cills and wide glazing areas help to reduce air infiltration. With secondary glazing and draughtproofing, the windows can be improved to increase their energy efficiency. However it is crucial to remember that such measures should be evaluated in relation to the overall appearance and integrity of the original window.

So, retaining existing historic windows that are in need of repair rather than replacing them makes sense, particularly when their thermal improvements can be achieved cost-effectively through simple repairs and upgrades. The windows of the past often have a historical value that demonstrates a range of technical development and changes in architectural style. The pressures to replace such windows are usually based on the assumption that old windows will need replacement in the near future, but most are still capable of serving for 150, 200 and even 250 years if they are properly maintained.

It is crucial to understand that decay problems in traditional timber windows are avoidable with timely and thorough repairs. It is also essential to identify damp problems and fix them quickly in order to avoid major damage. The early deterioration of paint can be a problem because it allows moisture to get into the wood, leading to wet rot. This type of damage is typically not noticed until the paintwork becomes damaged or wavy however, it can cause serious structural damage and lead to further decay.

A good paint will block moisture penetration. It is also important to keep the paintwork spotless to avoid condensation and mould growth. Modern synthetic paints pose a challenge because they are often water-resistant, and can cause mildew growth in the window frame.

The majority of windows from the past were made from timber that contained the majority of sapwood. These timbers can deteriorate quickly when exposed to rain, however they can be protected with an extensive preservation treatment prior to use. It is also crucial to ensure that the type of wood used is suitable to the site and climate conditions, as these factors affect the durability of the joinery. Local window manufacturers produce a range of sash made of timber that can be adapted to fit specific historic openings. They can be made according to the standard Boston pattern dimensions or to specific sizes that are in keeping with the historic architecture.

Maintenance

Regular inspection, careful redecoration, and quick repairs can prolong the lifespan of windows made of timber. The main cause of decay is moisture penetration through deteriorated paint and putty. This can be prevented by using a good wood preservative and thoroughly painting the wood.

Repairs to sash windows that are old and window frames made of aluminium casement windows cambridge should be handled with care and with minimal disruption.

It is essential to not remove old paint layers, which could have historical significance.

If a piece of timber has begun to decay, the best way to proceed is to take out the rotten material and replace it with spliced-in timber inserts that are shaped to match existing profiles.
