Suppliers of Handcrafted Sash Windows
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.

Modern Sash Windows – Facts & Figures
1
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. Double glazed and well insulated sash 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.
Traditional yet modern Thanks to advances in glazing technology, we can now provide sash windows with double glazing, and without compromising their historic appeal or significantly altering their elegant proportions. Our bespoke double glazed units are specifically designed to maintain the glazing bar look and sight lines that make traditional sash windows so distinctive.
Improved Energy Efficiency
Double glazing is popular in many homes for the insulation it provides, with the two layers of glass having air or gas trapped between them slowing down heat from escaping through the windows. Keeping heat in for longer means you will not need to have your heating on constantly, and your bills could come down as a result. You could also reduce the effect noise pollution will have on your home, as this makes it more difficult to sound to pass through your windows and cause a disturbance.
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:
Complete renewal
Most customers opt for this if they are carrying out building work in conjunction with their window replacements
Sash replacement
Your sashes will be upgraded to bespoke timber double glazed units. It requires less work than a complete replacement.
Draught seal and overhaul
This is our basic service. As part of this service we improve the existing sashes with various works.
Our service and window quality set us apart from other window companies.
Project Managed & Installed by Experts
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.
Buying British
At Wandsworth Sash Windows, we make all our windows, doors, and joinery by hand in our Sussex-based workshop. Help us support homegrown craftsmanship and create local jobs – buy British.
Frequently asked questions about double glazed sash windows
We understand that making the decision on which company to use to complete your home improvements can be daunting, so here are some answer to commonly asked questions that you may have in your mind and would welcome the opportunity to talk to you in person about your project.

Properly cared-for double glazed timber windows can last for decades, and many Victorian-era timber windows still grace homes across London today. Our newly crafted windows come with a comprehensive 10-year guarantee. To extend the lifespan of your windows, follow a few simple practices: use them regularly to keep mechanisms moving, clean them frequently (ideally every week), and repaint them every 5–7 years to protect the wood and maintain their appearance.
Condensation on double-glazed windows can sometimes occur. There are a number of tips for getting solving this problem. First, ensure your home is well-ventilated – so make sure you regularly open the windows. Another option might be the installation of a trickle vent. This is a small vent which when opened allows a small amount of air flow from the outside into the room – hence, the name trickle vent! Also, the use of a dehumidifier might be a good idea, and this has the added benefit of purifying the air in your home.
Wandsworth Sash Windows’ double glazed windows are guaranteed for a period of 10 years.
Prices can vary a lot because every company offers a slightly different service. For example, some companies do not include the windows to be painted or fitted and others do not include certification. It is important to compare the differences between the quotes you receive so you can make an informed choice. We would be happy to provide you with a quote, so please contact our team to talk you project through.
Yes, it is possible to restore double hung sash windows, although it depends on the extent of the damage and what you are looking to achieve. If you want a short-term fix then repairs is a good idea. However, if you want to achieve longevity, then replacement should be considered.
If you mean the double-glazed glass seal then the answer is no. Once the seal is broken, the glass will need to be replaced. As long as the window has been well-maintained then replacing the glass is not too complicated. Please feel free to contact our team to discuss your specific needs.
