How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows that are traditional and homeowners are proud of the way they look. Sash windows can become stuck and become difficult to open and close. This is usually due to moisture which can cause the timber to swell.

Traditionally, box sash windows utilized chains, cotton cords or weights made of lead to operate. Modern sash windows have hidden springs to overcome this problem.

1. Aesthetics

Unlike PVC-u windows that are constructed to modular imperial sizes, timber sash windows can be restored to their original size. This permits the re-installation of timber sash windows to comply with current energy standards and to comply with conservation area regulations. It also comes with a window that is far superior to uPVC options.

Sliding windows with sash were initially only used for large buildings or public buildings. However, this changed when production became cheaper and artisans could create larger frames using larger glass. By the end of the 18th century, sash windows were the most popular wooden design in British homes. Because they were simple to open sash windows allowed light into rooms without the need for curtains.

Early windows were plain glass, but by the 17th century sash windows started to become more attractive with coloured glass bars and moulded mullions. They were costly at first, but as glass production became less expensive and more efficient, they were a common feature in many period houses.

In the 19th century it was possible to create large, strong glass that did not need supporting bars. This allowed the frame to be enlarged which, in turn, provided an improved view. This was a significant innovation.

The introduction of the double-hung sliding sash was another important improvement that was made in the I920s and beginning of the I930s. The double-hung sliding sash is another important improvement that came into existence at the end of the I920s, and at the beginning of the I930s.

Oak was used for older examples and more prestigious buildings. It is essential to keep the separation bead that divides the sashes. This will help prevent rattles and draughts. It is also crucial that the idler and sash pulley wheels are in good shape as they aid in operating the window.

2. Energy efficiency

Sash windows replaced hinged cases as larger and clearer sheets were made available. Glass plates were set in frames made of timber, which were which were pinned with glazing sprigs, and putty was applied to the frame's two sides to ensure watertightness. This kind of glazing gradually replaced the leaded light bulbs.

The introduction of sashes led to an need for a greater variety of ironmongery, with the most basic fittings being brass pulleys, lead (and later cast iron) weights, sash stoppers shutter hinges, knobs and shutters and a variety of fasteners that secured the sashes into place. These were often decorated in patterns, inscriptions and patterns engraved to identify the maker.

With regular maintenance, sash windows are very energy efficient. However, if they are not maintained, they may become drafty and let in cold air. Paint and putty can cause draughts too. It is possible to fix this issue by using wood-to-timber solutions.

The industry of replacement windows relies heavily on the perception that older windows are beyond repair and cannot be maintained economically. However windows can be easily maintained with a bit of attention. Repairs can be costly and cause lots of disruption to the home. To prevent this homeowners often prefer to replace their windows with PVC-u windows from one of the largest "one-stop shop" installation companies. They can replace all windows in a house in one day, saving time and avoiding the need for different tradesmen to coordinate. They are also available with 'energy-saving' double-glazing to achieve more energy efficient ratings than are possible with traditional windows made of sash. These double-glazed windows aren't capable of replicating the proportions and sections of sashes from old timber.

3. Security

Traditional windows can be secured without compromising their appearance. Ironmongery, such as mortice bolts, sash chain and sash locks can be used. These can be installed in a manner that the window is able to be opened for ventilation and cleaning. These are typically unobtrusive, as they are designed to match the sash window. They can be utilized in conjunction with traditional sash window catches and are required to be replaced with more robust versions (such ones that have double screws) or spring levers to decrease the chance of them being opened by hammering.

Sash-window frames are typically constructed from oak or slow-grown deal. If the glazing bars are intact, they should be retained. If it is it is possible, the cills of the timber should be replaced with wood that is in line with. PVC-u companies often offer a one stop shop installation service, removing and replacing windows across a home in one day, without the need to involve other tradespeople or coordinate visits from different suppliers.

4. Ventilation

Sash windows were first introduced in the 17th century and allowed for a huge amount of light to enter buildings. At the end of the 18th century, they were adapted so that even more light could be let into the rooms. Larger glass panes were also produced. The result was a lighter appearance and windows that had a higher quality of design than before.

Sash windows were introduced, which required a new type of ironmongery. Early pulleys were made of wood. Later Victorian ones were made of brass or a mix of wood and leaded. There were also different kinds of knobs and shutter hinges. The ironmongery components should be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.

Timber windows require careful maintenance to keep them in good condition. Lack of attention to them regularly can result in:

Sashes that no longer slide easily.

window installation cambridge  in the frame allow water, which can cause damage and decay.

break down of putty allowing water penetration, which could cause decay in the frame and cill.

In the I920s and I930s, steel casement windows grew in popularity due to their strength slim and affordable and also matched the fashion for healthy living. Studies have shown that softwood sash window are just as efficient as PVC-u windows, and may even be more attractive.


The industry of replacement windows has made a significant effort to convince homeowners that their traditional windows are rotten, draughty and beyond economic repair. Many old windows made of timber can be fixed and used for a long time with minor repairs.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. Failure to do this can result in the sash cords breaking, a lot of wear on the glazing bars and degradation of the paint and putty. The removal of sashes can also result in structural movements within the frame, which can cause the sash to not close correctly. The sash could also get stuck in its open position, which allows water and draughts into the building.

Damage to windows made of timber is often caused by moisture penetration. This can be prevented by regular maintenance by thorough painting and eliminating the cause of dampness. The paint can be removed to expose the soft, rotting wood. The rotten timber sections must be removed with care, and the affected area should be snared together or pieced together using replacements of the same type as the remaining timber. This method of repair increases the amount of fabric used in the first place and is one of least invasive ways to treat timber-to-timber rot.

A wood condenser that is based on resin is an alternative to the traditional process of sanding or staining. It is brushed onto the surface of the wood to protect it and stabilise it. It is particularly beneficial in the treatment of sash cords and pulleys where it can help to prevent the breakage.

It is crucial that any ironmongery from the past such as sash stay and latches are kept and restored rather than replaced. They can be extremely difficult to replace without damaging the the original design. It is also recommended that the use of modern aluminium fittings such as sash lifts and chain stays should be avoided if possible since they can cause corrosion and deterioration of frames and sashes made of timber.
