Replacement of 10 casements
From initial survey to completed installation, TSWW provided a professional service. The initial survey indicated that we could just replace casements rather than the entire frames for 10 windows, providing a more cost effective quote than others we received. The installation team were courteous and responsive to a couple of issues raised by our decorator. We're very happy with the new windows.

Quality craftsmanship
New front door to replace arched cottage door.
Whole experience from initial enquiry through to installation was delivered with a friendly and professional service. The quality of the door and the process from visiting the workshops, having requirements confirmed, site survey and installation was a pleasure. Very pleased with our investment is a new wooden door that matches the original in looks but is secure, insulated and fits perfectly.

Very good experience with this company! They were honest about the work needed to install quality windows and it certainly feels like they undertook the right work for it!
Good service, good Accoya product. Our flat is instantly 2C warmer than it used to be!
Also the workers left the place in a clean state, nothing was damaged and they walked us through what to expect, how to take care of the windows to prolong life etc etc.

Unprompted review
EXTREMELY UNPROFESSIONAL
Extremely disappointed with their service. Came to do the works, then realised they put the wrong windows in and had to come again for a second time. We were charged BOTH times.
And the worst part? The second time, they made things worse than before because during the works, they removed the sash cords/spirals without authorisation, leaving the window unusable.
They then claimed the frames were too deteriorated and denied liability, despite the window working beforehand.
The outcome is a worse condition than before the works, with no accountability taken.

Reply from The Sash Window Workshop
We are sorry that you are disappointed with our service. We must, however, insist on setting the record straight.
You originally placed an order with us to replace the kitchen window as well as other windows. We explained that the kitchen window could only be replaced if the worktop and sink were removed as they were blocking removal of the old window. External access was not possible because the window was three floors up.
When we came to do the survey, you told us that you no longer wanted to replace the kitchen window as you didn’t want to remove the worktop and sink.
Although our clear recommendation was that the window be replaced, we then agreed to try to get the original window working better for you so you could have more ventilation.
When taking the window apart, we found that the window was too rotten to do what we had specified. Unfortunately, we also broke a pane of glass.
Please note that we were unable to inspect the window properly prior to starting the work and therefore cannot be held responsible for its condition.
We arranged a second visit to repair the rot and re glaze the pane for you as best we could. We then refitted the window on January 21st.
Contrary to your review, you were not charged anything for the work we could not do. We sent you two credit notes – one to refund you the full cost of the work we originally specified, but were unable to complete, and a further credit note as a goodwill gesture. All of the above points were covered in correspondence supporting the credit notes.
We acted with decency and integrity, refunding you in full because we were unable to complete the work as specified.
Your Trustpilot Review is wholly misleading. We ask that you withdraw your review immediately.
Simply - the best!
It's been a total pleasure working with this company. I needed a new front door, and from beginning to end everything ran smoothly- budget never changed,and schedule on time, all involved were totally professional and just genuinely very nice people! All my family and friends know about them.

Great quality window, friendly and professional service
After receiving various quotes we decided to go with the Sash Window Workshop, given their far superior customer service. The Workshop made and installed one large double glazed, acoustic laminate (8mm) sash window in our period property. Paul provided a wonderful service, and was available even after hours to answer questions. Jack did the installation for us and did a very good job. Both were very friendly and professional. We are very happy with the results, it is a solid window that provides both temperature and sound insulation. I would absolutely recommend the Sash Window Workshop.

A positive experience from start to finish!
My experience with the Sash Window Workshop was smooth sailing all the way. This UK based company is run by a professional and highly efficient team, who, from the moment of survey and quotation to the checking and overseeing of all final details, did not let me down. The quality of the product and their service has proved excellent at two different properties.

Beautiful Sash Windows
My experience with The Sash Windows Workshop was very good from the very beginning. Paul came and gave us all the information about the windows, installation and was available throughout the process. I realised that the people working for the company where very proud of their product and that was evident when I went to visit and have a look around myself. The installation of my windows was very quick and the guys that did it were very hard working, professional and courteous.

Very happy with our new windows
The joinery, glazing, draught sealing and paint finish are all good quality, and the TSSW team designed them to be a faithful copy of the original windows. The operation of the sashes is smooth, and with spacious opening. TSWW personnel have been professionally efficient throughout and the fitter took care to protect our furniture and floors during installation.

Superb Quality and Professional Service — Highly Recommended!
Having had an expensive window fitted by another company last year — which was unfortunately poorly installed and of disappointing quality — this time I did thorough research and chose a company with an outstanding reputation and top-quality products. I honestly cannot praise them enough for their superb service, highly professional installation, and meticulous attention to detail. The windows themselves are exceptionally well-made — solid, beautifully finished, and fitted to perfection. These new windows feel premium in every way, and I’m already looking forward to (and hopefully saving up for) having the main front windows done one day.

Extremely happy, I would not hesitate to use them again or recommend them. From the very first visit and…
From the very first visit and throughout the process this company's communication was excellent. In fact I have never had such a perfect experience. I was also exceedingly happy with the end result. My old window frames were very old and crooked but they managed to do a great job despite the challenging conditions. Having had many quotes, theirs was also very competitive.

The responsive 1st contact. The accurate inspection. The rapid and clear proposal. The communication post acceptance for a date that suits us. The professional installation by experts. The minimum fuss to us and the neighbours. And of course the exceptional quality of the windows. Start to Finish- Just a Brilliant Experience. Thank you.

Excellent Quality
The final product was outstanding. The windows look amazing, and have given a significant noise and temperature improvement. I'm very impressed with the period look but modern quality.
Installation was quick (one day, done by 2pm) and from measurement to installation is pretty good at around a month.

Excellent. They took a lot of care to get everything just right with the design and installation was painless. One of the things I liked was the fact that when the engineer wasn't sure about an aspect of the installation, he called in and someone was there to help him within the hour, to ensure it was right.

Excellent Experience
I had an excellent experience with the Sash Window Workshop recently. They manufactured four new sash windows and a new kitchen door for my house.
The high quality of the manufactured parts really stands out, and has transformed the rooms in which they were installed. Pricing was competitive and undercut another company that priced the job for me.
The door has an ERA multipoint lock (which I wasn't expecting) and, aside from looking much nicer, is vastly more secure than the door it replaced.
Installation took place on the agreed date, took exactly the number of days forecast and was commendably professional.
Very impressed, thank you.
