SashWise Limited West London's sash windows experts Based in Teddington/Twickenham, SashWise specialises in the repair, restoration and replacement of wooden sash windows.

For 10 years, Dan, the owner, and our highly skilled team of craftsmen have delivered exceptional levels of service at a competitive price. We only use the best quality materials and take extreme care in your home. The services we offer are:

Servicing and draft proofing helps you to save heat, eliminate drafts and improve sound-proofing, as well as ensure your windows open and close smoothly again. Any rot found is also repaired on site. Full restoration guarantees your sash windows are returned to their former glory to maintain the architectural heritage of your home. Our extensive restoration services take place at our local workshop where we take the windows back to wood so that all rot is revealed and then repaired. Double glazed new hardwood sashes guarantee heat retention and reduced noise levels. We make new double-glazed hardwood timber sashes to fit within your original box sash frame – a more cost-effective option to replacing the whole of your sash window. We are skilled at replicating the exact style and detail of your existing sashes so that they maintain the traditional character of your home. Free survey and quotation:
We provide a free site survey and a quotation which is tailored to your individual needs. If you live in the boroughs of Richmond, Twickenham, Kingston, Chiswick, Ealing, Wandsworth or in any neighbouring areas – take the first step in discovering a quieter, warmer and more secure home through the restoration of your sash windows. Call us today on 0208 977 4627 to discuss your individual requirements.

Privacy without compromising on natural light 🪟

Bathrooms, en-suites and cloakrooms need privacy, but that doesn’t mean they have to feel dark or closed in.

Etched or frosted glass provides additional privacy while still allowing plenty of natural light to flow into the room, making it a practical and attractive choice for spaces like this.

It can also be incorporated into double glazing, combining privacy with improved thermal insulation.

Because sometimes it’s the smaller details that make a window work perfectly for your home.

We don’t just turn up, install your windows and disappear. 🪟

We want you to understand the work being carried out on your home, why we’re doing it and what goes into getting every detail right.

From the initial conversations through to installation, we aim to keep the process transparent, informative and collaborative, so you can feel confident in the work being completed and maybe even learn a little along the way.

It was lovely to receive this feedback following a recent project.

Turning a house into a home isn’t always about what’s on the inside. 🏡

There’s something special about pulling up outside and feeling proud of the place you call home. Your home is a reflection of everything you’ve worked for, and that feeling should start before you even walk through the front door.

Beautifully crafted timber windows don’t just complement your property, they help preserve its character, enhance its kerb appeal and make coming home feel that little bit better.

Because you should be proud of your home, inside and out.

There is a reason timber windows have been used in homes for generations.

For period, heritage and character properties in particular, timber offers a traditional appearance that can be tailored to complement the style of the individual property, without having to compromise on modern performance.

At SashWise, we supply and install bespoke timber sash and casement windows, as well as single and French doors, combining traditional design with modern glazing, insulation and security.

Do your timber windows really need replacing?

Not always. Depending on their condition, existing timber windows can often be repaired, restored and improved, helping to retain the original character and craftsmanship of your home.

At SashWise, we assess your existing windows first and recommend the level of work they genuinely need, whether that is servicing and draught-proofing, rot repair, full restoration or replacement.

If you are unsure what condition your timber windows are in or what work they may need, get in touch with the SashWise team to arrange a consultation.

One of the best compliments we can receive when replacing an original timber window is that you can barely tell it has been replaced.

We recently returned to the Old Manor House in Shepperton, where our team installed a new window designed to retain the character and appearance of the original.

Following the work, we received this lovely feedback from Mark.

Thank you to Mark for taking the time to send this through, and to the SashWise fitting team for another job completed to such a high standard.

A recent project completed in East Molesey for a large mid-Victorian villa within a conservation area.

With the original character of the property needing to be retained, the replacement vertical sliding windows and fixed sidelights were carefully designed to closely replicate the existing windows.

We’re pleased to hear the customer was so happy with both the finished result and the service from the SashWise team.
