Maintaining Timber Windows

A well-maintained and maintained timber window is an important element of the historical fabric of a building. It illustrates in varying degrees the materials and technologies, craftsmanship and architectural taste of the time that it was built in.

Whenever possible repairs to existing windows are required, they should be carried out in situ. Proprietary resin-based repair systems can be used to repair the most damaged areas of decay without removing the whole window.

Durability

Timber windows were made to last for centuries. They do require maintenance to keep them looking great. Maintenance tasks include repairs to sash cables, retightening of pulleys for sash and painting. There is a growing need to upgrade the timber windows to increase energy efficiency. This could mean replacing old glass units, fixing the window rebates that are in place or putting up new cills the air to seal better.

A key problem 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 very large. In these situations water can get into paint film and cause rotting to the wood or putty beneath. The rotting may be further aggravated due to weather conditions that are poor. To avoid this windows, they should be painted regularly using a suitable exterior wood paint.

The areas that are damaged should also be repaired using a resin-based product. This will ensure that the best possible amount of the original fabric remains. It is also important to limit the number of holes you drill into the frame for cable entry since these could allow water in and cause decay.

Another significant problem with older windows is structural movement in the wall that can cause deformation of the frame and the sash. This can lead to the sash not fitting properly or sticking or jamming into the opening and broken glazing. Most often, this is corrected through the installation of new sash boxes made from slow grown deal (pine) or oak. The cill needs to be constructed of a strong hardwood like oak, to prevent differential movement between new and older work.

To reduce the risk There are a variety of companies that make Boston pattern sash made of wood that will fit most existing openings. These sash window repair cambridge come in a variety of sizes and finishes that meet the requirements of modern-day homeowners. These new sash, when combined with quadruple draft strips and a more efficient thermal insulation, could make a significant difference to the energy-efficiency of a home.

Aesthetics

Many old wooden windows have an excellent aesthetic value since they usually show, in a particular way, the materials and technology and architectural taste of the time in which they date. They also may have a significant historic value 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 structural frames subdivided horizontally by mullions with vertical wood or iron bars to protect against intrusions.

Traditional window joinery made from timber can be a highly decorative element of a structure and is crucial to maintain its appearance. When you spot any signs of decay caused by water penetration, it is important to stop it. This is best accomplished by painting thoroughly, especially in areas that have already suffered damage or degradation. It is advisable to use paints that are specifically designed to be used part of a system (primer undercoat, finish) and follow the manufacturer's guidelines in terms of preparation and number of coats needed at each stage.

Wet rot is a common problem in old timber windows and the best method to stop it from growing is to eliminate sections that are damaged or rotten as soon as possible to stop the spread of the fungus responsible for it. Replace rotting wood with slow-growing deal (pine), and should it be possible, the same type of timber that is being removed, to prevent differential movement.

In the late period of the 17th century and the middle of the medieval period, glass became more affordable and abundant, and the openings for double glazed door Seal repairs glass in timber-framed buildings gradually became sophisticated with wooden tracery moulded mullions, moulded mullions, and deep projection cills. Increasingly, the glazing was placed within frames with rebates and secured by 'glazing sprigs' rather than being inserted into lead cames. This method of glazing is not just less susceptible to leaks, but also allows for more expansive clearer, more transparent sheets of glass to be used in windows than would 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 the smallest of details. They also feature large glass areas as well as deep projecting cills that reduce air infiltration. Windows can be designed to increase their energy efficiency through draughtproofing and secondary glazing. However it is crucial to remember that such measures should be evaluated in the context of the overall quality and appearance of the window in its original form.

It is logical to fix or upgrade windows that are older rather than replacing them, especially when the improvements in thermal efficiency can be made through simple fixes. The windows of the past often have a historical value that shows a variety of technical development and changes in architectural tastes. Most people assume that the windows will need to be replaced in the near future. However, they will last for 150, 200, or even 250 years with proper maintenance.

It is essential to realize that decay issues with traditional timber windows can be avoidable with timely and thorough repairs. In addition it is crucial to recognize damp penetration issues and address them swiftly to avoid serious damage. Paint deterioration that occurs early could be a problem as it allows moisture to penetrate into the wood, leading to wet rot. The damage is usually not noticed until the paintwork becomes cracking or wavy, but can cause significant structural damage, and could lead to further decay.

A high-quality paint will stop this moisture from entering. To avoid condensation and mould, it is important to keep the paintwork as clean as you can. The use of modern synthetic paints can be problematic because they are usually formulated to be water-resistant, which can cause the growth of mildew inside the window frame.

The majority of windows from the past were made from timber that contained the majority of sapwood. These timbers deteriorate quickly if exposed to rain, however they can be preserved with a thorough preservation treatment before use. It is crucial to select the right type of wood for your location and the climate, since these factors can affect the longevity of the joinery. Local window repair specialists manufacturers create a variety of timber sash that can be customized to fit specific historic openings. They can be constructed according to the standard Boston pattern dimensions or to custom dimensions that are compatible with the historic architecture.

Maintenance

The lifespan of windows made of timber can be extended considerably by regular inspection carefully redecoration, and timely repair. The primary reason for decay is the infiltration of moisture through the deterioration of paint and putty. This can be avoided by using a good wood preservative and painting the wood thoroughly.

It is important that repairs to old sash or casement windows are properly executed and completed with the minimum disturbance. It is possible to upvc door repair cost several traditional designs of timber windows without having to remove the frame. This should be done as often as is feasible. Paint that is peeling or loose should be removed with care and lightly sanded to improve the "key" of the surface, allowing for a better adhesion of the new coating. It is important to avoid removing old paint layers, as they could have historical significance.

Where a section of timber has become rotten the best course of action is to eliminate the rotten material and replace it with spliced-in timber inserts that are shaped to match existing profiles. The wood that is being inserted should be treated with a wood preservative and the joint between the timber cill and sub-cill for masonry should be sealed.

Replacement of windows made of traditional PVC-u is an appealing option, particularly when the installer provides a 'one stop shop' installation service that can handle both removal and replacement within one day. It is crucial that the person who installs replacement windows has a complete knowledge of the structure and history of traditional wooden frames. This will enable them to make the right recommendations for energy efficiency improvements and other technological upgrades that won't harm the historical character of a building. Window replacements should be registered with a Competent Persons Scheme such as FENSA. This will ensure that the replacement windows are approved as a suitable solution under Building Regulations. A skilled carpenter can install PVC-u windows that conform to the original building's style. This is especially true when the windows are located in listed buildings and conservation areas.
