Sash window replacement in London

Sash windows became popular in the UK during the Georgian and Victorian eras and they are a typical feature of traditional, period British homes. Many people are desperately in need of new windows, but want to retain the character of their home. If your property still has its original windows it is more than likely they are going to need to be replaced.

We are experts in keeping a property’s character after replacing sash windows. All our windows are handmade in our UK-based workshop using British joining techniques – everything from the frames to the glass are made specifically for you. These are different to the techniques used within the rest of Europe and will ensure your windows look perfect for your period property. We will supply and fit your windows for you, ensuring a professional approach throughout.

How Wandsworth Sash Windows can help you

Our customers often come to us wanting wooden double glazed windows, but are unsure how to achieve this. We offer two distinct services to our customers – many other companies offer just one.

  • Complete renewal (complete new box frame and double glazed sashes). Our most comprehensive service for sash windows is to remove the old window, and fit a completely new one. Architraves, window boards and more are included to ensure that you are left with the best possible finished product. Our installers have worked in period properties for years, so they know how to work with and around the quirks that older buildings throw at them.
  • Sash replacement (new double glazed sashes installed into the existing box frames). This is our most popular service for sash windows as it lets you enjoy all the benefits of double glazing, without quite so much work. When fitting new sashes into your existing box frames, our carpenters will fully draught seal your windows, hang the window on new cords and fit a complete set of ironmongery. On request, we can also repaint the existing timber – just ask.

Replacement sash windows – traditional appearance with modern efficiency

At Wandsworth Sash Windows, we believe very strongly in the benefits of making all sash windows by hand. This means we can tailor the appearance to meet your exact requirements and make sure it is perfectly in keeping with the rest of your property.

Why choose Wandsworth for your new sash windows?

We are strong advocates of the importance of keeping sash windows looking true to your property. They are made, measured and installed by us as well, so we always achieve a perfect fit. Here are some of the reasons why we are the right people to supply and fit your sash windows:

We hand-make all our windows

We use mortice and tenon joints rather than screws, and you won’t find any large machines for mass production in our workshop. Everything is made personally so we can take care of the details, like matching wood grain and providing a hand painted top coat.

Our installation team fit your windows for you

They are all experienced carpenters, which is important when working on period properties – you can’t guarantee what you will find when an old window is removed. Unexpected findings could hold up the work, but not for us. We make changes to windows in situ so we can fit them as planned.

Quality is second to none

Many European windows are made from pine and are screwed together, or they use substandard jointing methods. Not ours. We use Scandinavian kiln-dried redwood with mortice and tenon joints to provide a superior finish. Redwood is stronger than pine and won’t begin to distort and bend over time.

One point of contact

You will easily be able to get hold of the person you need at our head office, and you’ll receive a personalised service. The team will ensure you are kept informed about the progress of your project at all times, making regular contact throughout the process. Meet our team here.

How do new sash windows help your home?

New sash windows have so many benefits for your property. By installing new windows that are made to measure and fitted by experts, you’ll be able to eradicate many of the problems that can develop over time. These are some of the ways new sash windows can improve your property and your lifestyle:

Better appearance

Getting rid of old, rotting, rusting windows will really lift the appearance of your property. We use British joinery techniques and Scandinavian kiln-dried redwood for strong windows that stand the test of time.

Good insulation

Modern sash windows will use better glazing and will be made from insulating materials that improve heat retention.

Improved soundproofing

New windows will be properly sealed, and we can upgrade your glass if soundproofing is a concern.

Windows are an intrinsic part of the home and by installing new ones, you can help improve the value.
