Many people who own single glazed traditional timber sash windows are often frustrated that their homes are cold and draughty. They therefore consider replacing their beautiful old windows with ugly modern plastic ones. This is not necessary, however, thanks to the sash window double glazing service offered by We have fitted double glazed sash windows in Liverpool many times before. 

What’s Involved?

To double glaze sash windows, we first remove the sash beading and the top and bottom sashes. We assess the sill’s condition as well as that of the box frame and external pointing. Should they be of good enough quality, an entire window replacement is not necessary. Once we have taken precise measurements, we create replica sashes, matching the sash horns and inner moulds to the originals and fitting them with double glazed units which meet all current building regulations. Our double glazed units are made up of two panes of glass, between which is sandwiched an inert gas. Heat lost via the windows is vastly reduced, because the gas is a poor conductor of heat. To further improve the energy efficiency of your property, we also install a concealed draught proof system

Next, we prime all the exposed woodwork and caulk the beading, leaving the window ready to decorate. If required, we also offer a painting service, using our recommended decorator scheme. We’ll then fit a centre catch, up-lifters, sash eye and window locks in any style you like. We can advise on which window furniture is best suited for your property.

Once the window has been fitted, we provide you with a full operational demonstration. We’ll advise you on the best way to look after your new double glazed sash windows to keep them looking their best for years to come. 

This method means that you make a considerable saving when compared to replacing the entire window. As a result, prices start from as little as £580.

Double Glazed Sash Windows in Conservation Areas

Windows make a hugely important contribution to the appearance of all properties, but nowhere is this more evident than in historic buildings in conservation areas, which have protected status due to their unique and distinctive architectural features. Sash windows are an important part of our British heritage and so should be preserved wherever possible. 

A common misconception that we often come across is that double glazed sash windows cannot be fitted in listed buildings, or in properties located within conservation areas. However, this is simply not true. Our dedicated team has years of experience ensuring that all of the windows they produce and fit are sympathetic to the architectural requirements of the area. As our double glazed sash windows are produced as exact replicas of the originals, we almost always receive planning approval from local planning authorities. We are able to handle all of the paperwork necessary to gain approval.  

In conservation areas, other types of window are entirely inappropriate and should be avoided at all costs. You should not be tempted by their lower cost. The damage they do to the overall appearance of a property is simply not worth this small saving. In fact, by fitting such windows, you may dramatically reduce the value of your period property when it comes to selling your home.
