About

The Sash Window Workshop specialise in manufacturing and installing traditional timber windows and doors in London and the south of England. Windows and doors are designed to improve energy efficiency, while retaining the traditional character.

Operating out of our factory in Berkshire, we manufacture bespoke sash windows, casement windows and external timber doors. If the frame is still in a good condition we can just replace the moving parts.

We also offer bespoke secondary glazing and a draught proofing service for timber windows.

Our aim is to deliver excellence at every opportunity and our experienced team of sales surveyors will ensure that you are provided with the solution that meets your needs.

We are proud that roughly half our orders come from existing customers and recommendations, highlighting our high quality products and excellent customer service.

Fabulous new front door

Our newly installed front door is fabulous! The whole experience from initial contact, preliminary design, survey & final installation has been excellent. The professional, helpful approach from everyone we have dealt with was exemplary and a credit to the company. The quality of products & standard of the installation work was exceptional in every detail & the finish was superb. We can only praise The Sash Window Workshop & would, without doubt, highly recommend the company to others.

We chose the Sash Window Workshop having asked neighbours for recommendations and after having obtained quotes from 2 other companies. Replacing sash windows in a conservation area was never going to be cheap but given the number of new windows we were having installed we thought that the estimate for the work was pretty reasonable. From the initial survey right through to the installation the company were extremely efficient and helpful . Everything was delivered on time and to a very high standard . The window installers worked extremely hard and left everything clean and tidy . We are thrilled with our new windows and they definitely make the house a lot warmer and quieter . The new windows were installed in Oct 2023 and unfortunately on Feb 2024 we had an attempted break in, the intruders didn’t gain access but they did succeed in damaging one of the new sash windows , which fortunately was covered by our insurance. After some discussion the Sash Window Workshop said they were confident they could effectively repair the damage rather than having to make a new window which they did and the repaired window , looking as good as new , was reinstalled yesterday . Through the service has been really excellent and we would highly recommend the company to anyone looking to have new sash windows fitted .

We asked the Sash Window Workshop to provide a quote for secondary double glazing for an upstairs window due to increased traffic noise. The sales visit was very informative and helpful and at no point did it feel like we were being given a hard sell. It was recommended that we instead replace our window with a double-glazed option made to match the one being replaced but with sufficient gap and additional acoustic glass. Throughout the process of survey, manufacture and the lead up to installation, communication was excellent and always polite and friendly. We were helped to find a scaffolding company, and on the day of installation, the fitters arrived promptly and took care of our home, working carefully and cleaning up afterwards ( not a great deal required but it was appreciated). The window is now in, looks perfect and provides a huge improvement in noise. I can't recommend them highly enough. Extremely well made windows in keeping with our house.

Victorian bay windows replacement

We had the original 1850s bay windows on our house replaced and the fifty year old secondary glazing removed. Communication between the company and us was efficient, the survey was thorough and the installation went smoothly. Plenty of dust sheets were provided and the installers were pleasant and hard working. We are very pleased to now have windows we can open easily. The rotted sills were also replaced and the windows look great both inside and out blending well with windows which were not replaced.

The company replaced four sash windows for us. We were impressed by the professionalism throughout from the initial advice on options to the carrying out of the work. Everything happened as it should and when it should. We can highly recommend this company.

We recently replaced our traditional Edwardian, single-glazed sashes with like for like double glazed equivalents. Prior to the installation, I visited the Sash Window Workshop to have a look around and was extremely impressed with the setup and was not disappointed with the quality of the product when it was delivered and installed. The installers were professional, courteous and polite at all times and the aftercare impeccable. When some slight issues arose (mostly due to user naivety) a member of staff was dispatched promptly to deal with them. Overall - Impressed, I would have no hesitation in recommending the company or the product.

The Sash Window Workshop were professional and helpful at all stages from our initial inquiry to completion. The job was tricky, fitting new double-glazed draught-proofed sashes into existing frames and required an extra visit which was carried out promptly. We are very pleased with the results.

The whole process of doing business with the Sash Window Workshop has been totally professional and efficient. Every step has occurred as and when described. From the salesman, Joe Parkinson’s visit, to the installation by Ryan and Attila with their team. Everything has gone smoothly. The product appears to be really good quality and the installation, swift and efficient with such attention to detail, safety concerns and impeccable tidying up - the whole experience painless and the result, beautiful. I am sure we can already see, feel and hear the benefits. Also the patience required while the grinding machinations of the (ridiculously unnecessary) Kensington and Chelsea planning department resolved to grant permission. Thank you for sticking with me! So, in conclusion, five stars all round for every aspect of the Sash Window Workshop’s work. Plus a special note of thanks to the very skilled, Ryan and Attila - who were exemplary… Thank you for looking after me so well. I would have no hesitation in recommending the company to anyone and everyone.

The BEST in the business

I can't speak too highly of The Sash Window Workshop and I implore you to use them if you are looking for new windows or a door. The reason I'm so effusive is that I used another company when I first moved into my new house to do the front windows. The Co which will remain nameless (unless you want to contact me) had a very impressive website and strong reviews but we felt very let down by the service. The windows themselves were good thank god. But the service was really lacking and the engineers were shocking. I'm making this clear because windows cost thousands of pounds and it's a scary commitment. And that feeling of being let down never leaves you. When I found Sash Windows Workshop it was to the front door and from the first meeting with Stav the front/salesman it was a delight to do business with them all. The surveyors, the engineers, everyone. Plus the door itself is a solid piece of art. A beautiful thing to behold. I was so impressed I got them to do my back windows and they've just completed another perfect job from start to finish. You cannot mess around when choosing a window company. These people are just so nice, so knowledgeable, so polite, so tidy. Plus they've all worked at the company for many years and you can tell they are all part of a family and respect one another. If you want the best, look no further. You will be very happy.
