Maintaining Timber Windows

If possible, repairs should be made on-site. The repair system that is based on resin can be used to fix the most deteriorated areas without removing the entire window.

Durability

Timber windows were built to last for centuries. However, they need to be maintained to ensure that they look good and operating properly. The most common maintenance tasks include sash-cord repairs, re-tightening sash pulleys, and painting. There is also a rising demand for upgrading timber windows to improve energy efficiency. This could include replacing old glazing units, repairing existing upvc window repairs near me rebates or installing new cills to increase the air seal.

The deterioration of paintwork is a major issue with traditional windows. This is especially true in the case of sash windows, as the gaps between sashes can be quite large. In these circumstances water can get into the paint film and cause rotting of the putty as well as the wood underneath. Poor weather conditions can exacerbate the decay. To prevent this windows from becoming rotten, they must be painted regularly using a suitable exterior wood paint.

Areas that have been damaged must be repaired using resin-based products. This will ensure that the maximum possible amount of the original fabric is retained. It is important to minimize the number of holes made into the frame to allow cable entry since they can let in moisture and cause decay.

Another significant problem with older windows is structural movement in the wall, which can lead to deformation of the frame and the sash. This can lead to sash not fitting correctly jamming, sticking or sagging in the opening, and broken glass. This can be corrected often by putting in new sash frames constructed of slow-growing deal (pine), or oak. The cill should be constructed of a strong hardwood like oak, to avoid shifting between the new and old work.

There are a variety of companies that make Boston pattern wooden sash that fit most existing openings. These sash come in various sizes and finishes that suit the needs of modern homeowners. The new sash, coupled with quadruple draft strips and improved thermal insulation can significantly improve the efficiency of a home's energy use.

Aesthetics

A lot of old timber frames possess a dazzling aesthetic appeal, as they reflect, in some form, the quality of the wood, technology, and architectural aesthetics of the time they were made. They may also have significant historical value in their individual cases. This is especially true of early unglazed windows in timber-framed structures, where the majority were series of openings within frames of structural construction, which were divided horizontally by mullions, and vertically by iron or wood bars in order to protect against intruders.

Traditional window joinery made of timber can be a stunning aspect of a building, and it is important to keep it looking good. When you spot any signs of decay caused by water penetration it is crucial to stop it. It is best to do this with thorough painting, especially if there has been damage or degradation. It is advisable to use paints that are specifically designed to be used as part of the system (primer as well as undercoat, finish and primer) and to follow the manufacturer's recommendations in relation to preparation and number of coats required at each stage.

Wet rot is a frequent problem in old timber windows. The best way to stop it developing is to remove any damaged or rotten sections as soon as possible to prevent the spread of the fungus that causes it. Replace the wood that is rotting with slow-growing deal (pine), and should it be possible, the same type of timber as the one that is being removed, to avoid the possibility of differential movement.

Glass became cheaper and more abundant during the late medieval period and into the 17th century. This led to the openings for glazed windows on timber-framed houses became more complex with moulded mullions, tracery made of wood and deep projecting cills. The glazing was increasingly laid within rebated frames and then pinned with 'glazing sprigs' rather than into lead cames. This method of glazing is not just less prone to leaking but it also allows larger clearer, more transparent sheets of glass to be used in windows than would be possible without the need for leaded lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness and multilayer construction as well as focus on the smallest of details. They also feature large glass areas and projecting cills that minimise air infiltration. The windows can be made to improve their energy efficiency with draught-proofing and secondary glazing. However it is essential to remember that such measures should be viewed in terms of the overall quality and appearance of the original Window mechnism repair.

It is sensible to fix or upgrade historic windows rather than replace them, especially when the improvements in thermal efficiency can be made through simple fixes. Older windows typically have an historic value that demonstrates a range of technical development and changes in architectural taste. Many people believe that the windows will need to be replaced in the near future. However, they are still in service for 150, 200 or even 250 years if they are maintained with proper maintenance.

It is important to recognize that decay issues in traditional timber windows are preventable by quick and thorough repairs. In addition it is crucial to spot damp penetration issues and to remedy them quickly to avoid major damage. Paint deterioration that occurs early could be a problem as it allows moisture to get into the wood, causing wet rot. It is not uncommon for this type of damage to go undetected until the paintwork starts to crack or turn wavy. However, it can cause structural damage and further decay.

A good quality paint will stop this moisture penetration. To prevent mould and condensation it is essential to keep the paintwork as clean as you can. Modern synthetic paints pose a challenge since they are usually water-resistant, and can cause mildew to develop within the window frame.

The majority of windows from the past were constructed from sapwood-rich wood. These timbers are susceptible to deterioration quickly when exposed to moist weather conditions, but they can be preserved with an extensive preservative treatment prior to when they are put to use. It is also important to ensure that the type of wood used is suitable to the location and climate conditions, as these elements can affect the longevity of the joinery. Local window manufacturers offer an array of timber sash which can be customized to fit historic openings. They can be made according to the standard Boston pattern dimensions, or to custom dimensions that are compatible with the architectural style of historic buildings.

Maintenance

The lifespan of windows made of timber can be extended by regular inspection, careful redecoration and timely repair. The most common reason for decay is the infiltration of moisture through the deterioration of paint and putty. This can be avoided with careful painting and the use of an excellent wood preservative.

A lot of traditional wooden window designs can be repaired without dismantling the frame, and this method should be taken whenever feasible. Paint that is peeling or loose should be removed with care and sanded lightly to increase the 'key' of the surface and allow for an easier adhesion of the new coating. It is important to not remove old paint layers, as they could have historical significance.

If a piece of wood is rotting the best way to deal with it is to take it off and replace it with timber inserts that are shaped to match existing profiles. The wood that is being inserted should be treated with wood preservative and the joint between the timber cill and the masonry sub-cill should be sealed.

Replacement of traditional windows using PVC-u is an appealing option, particularly when the installer offers a 'one stop shop' installation that takes care of both removal and replacement windows cambridge within the span of a day. It is, however, vital that the installer of replacement windows has a full knowledge of the structure and history of traditional timber frames. This will allow them to make the right recommendations for energy-efficiency improvements and other technological improvements that don't alter the appearance of an historic building. The windows that are replaced must be registered under a Competent Persons Scheme like as FENSA. This will ensure the replacements are deemed to be approved by the Building Regulations as a suitable option. A skilled carpenter is able to install PVC-u cambridge windows that are suited to original building's character. This is especially applicable when windows are in listed buildings or conservation areas.
