We are suppliers and installers of bespoke sash windows, handmade and hand painted in our UK workshop. This means you can choose everything, from the configuration of your windows to the exact colour of your paint. We will create the perfect windows for your property, improving aesthetics, insulation and soundproofing.
Our windows are made from Scandinavian kiln-dried redwood, which is strong and robust, though if you would like to use a different wood type we are always happy to accommodate you – please enquire.
Sash windows are made of moveable panels, also known as sashes, that sit within a frame. There may be one pair of sashes per frame, or one frame may contain multiple sashes. They can be used in many different types of building and can be customised to suit your purpose.
Sash windows emerged as an innovation due to new legislation after the Great Fire of London in 1666. They have become something of a staple in the UK ever since, especially in London. A lot has changed in 350 years – architecture, house styles, house prices… – but the sash window has remained and stood the test of time.
What do our customers think?
Sash window facts and figures
In a poorly-insulated room with ill-fitting windows, the air is completely changed around three times every hour. This means you are paying to heat air that is then simply lost, driving up the price of your energy bills. Well insulated windows save money.
Sash window technology has improved drastically. It is now possible to use unbreakable cords, and staff beads that will drastically improve insulation with integrated draught proofing. If your windows have not been overhauled in a long time, you could really benefit from new technology that has become available.
The very first sash windows date from the 1670s. They create a typically British, aesthetically pleasing appearance. You can replace or renew your sash windows to highlight the historic charm and appearance of your property.
What are the benefits of retaining period sash windows?
Attractiveness The main reason for having sash windows is the aesthetic value they add to a property. They can be fitted into a variety of properties, from Georgian through to modern day new builds. It is simply a question of finding the right configuration and design for your property. Sash windows can be made of slimmer sections than casement or UPVC windows, allowing in more natural light. This also gives them a subtler appearance, which complements classical styles and becomes a key design feature of buildings from the Queen Anne and Georgian periods.
Practicality Sash windows can be finely adjusted to control ventilation. A narrow gap can be opened at either the top or bottom to allow fresh air into the property without the issue of rain blowing into the room. By adding restrictors, sash windows can be locked open to make them more secure whilst also allowing ventilation.
Longevity Sash windows are hung from each of their top corners, rather than from the side like a hinged window. This makes them less likely to distort under their own weight so they will have a longer lifespan. Many sash windows are still serviceable after 100 years or more. Compare this to uPVC windows, which need to be replaced roughly every 20 years.
Sash windows that are as unique as your property
We are the sash window experts, crafting beautiful, handmade windows in our very own workshop.
We offer three main sash window services:
Our service and window quality set us apart from other window companies.
We project manage throughout, so you can leave all the details to us. Your window manufacture and fitting processes are all carried out by our in-house team, so we are fully accountable for our work.
Installing or repairing a sash window correctly is just as important as the production process. That’s why our carpenters are all-round sash window experts. It’s much trickier to fit sash windows into older properties – it’s impossible to know what lies behind an existing window until it is removed. For many companies, this creates a serious disruption. Not for us. Our installation experts can make any adjustments necessary on site, making the fitting process simple.
