Find Out How Period Sash Window Restoration Will Increase The Sale Value Of Your Property

Sash windows are one of the important parts of the heritage of many of our towns. Many buildings have a character which is dependent on the retention of the building’s original features such as these elegant windows. Retaining original features is more than just a matter of taste, it can also make good economic sense. Period windows were often made with higher qualities of wood than are used today, and most real estate agents feel that having original features will add value to any property, and make it sell more quickly. This short article shows how sash window restoration can increase the sale value of your property.

Single-hung sash windows were probably invented by the French, and copied by the British during the seventeenth century. After that introduction, the double-hung sash appears to have been invented in England, and it allowed much more subtle ventilation than in the older side hung casement windows which were prevalent in earlier buildings.

Until about 1700 many windows used native oak, and other hardwoods, but as these woods were becoming rarer and more expensive, they were replaced by what joiners called deal. This included various softwoods from fir and pine trees.

Although many timber windows built in the 1950s and 1960s have already deteriorated, sash windows from the eighteenth and nineteenth centuries may often be found in good condition. This is because the Georgian and Victorian builders used the more expensive, and higher quality heartwood, from the center of the tree, rather than the cheaper sapwood, which is often unsuitable for external joinery.

It is important in any repair or refurbishment to use the best quality heartwood, or if that is not available, to use sapwood which has been well treated with timber preservative. It is a myth that all softwood is poor quality. There are many excellent quality timbers available from managed forests in the UK, Scandinavia and North America, which may be expected to last for decades or even centuries.

Windows may be repaired using appropriate materials and modern timber preservatives, and the use of modern paints will lengthen the time needed between new coats of paint. There are also improvements such as built in weather seals which can be incorporated during the refurbishment. The sashes are removed and grooves are machined in them to accept these discreet seals, which eliminate draughts and rattles.

The original window glass can be replaced by low E laminated glass, which improves the energy efficiency and reduces noise intrusion into the home. Secondary double glazing is also an alternative for those who wish to further improve energy efficiency. Modern locking devices may be fitted. These will improve security, and make homes safer for younger children. Home insurance costs may also be lower if improved locks are fitted.
