London Box Sash Windows Ltd

Since we moved into our Victorian house three years ago, we have been working our way through replacing the existing windows which were pretty much held together by paint. We saw a number of companies initially but settled for London Box Sash Windows due to the quality of the product but also the strong sense of a family company. We have had around 14 windows replaced now over 3 stints and not had any regrets. The latest installation of two windows was completed two weeks ago. The quality is excellent and with the Accoya wood we haven't had any sticky frames or needed any other follow up adjustments. It is always a pleasure to deal with Patrick and Jack during the order process and you are kept well informed throughout by Judith in the office. The installers Francois, Ramunas and Andy have all been extremely professional and taken great pride in their work. And at the end of it all, we are left with some beautiful windows inside and out which have enhanced the house. And we still have more to sort so will be back in the future.

London Box Sash did a great job - my windows look great! You get the feel of a family firm when Jack comes to measure for the quote, and then brother Patrick for the more detailed survey. Our windows were fitted by Ramunas and Angelo, who were very polite, bust a gut to get it done as quickly as possible and cleaned up after themselves. Highly recommended!

I looked at a number of sash window companies and am very happy I made the right decision to go with London Box Sash. The service and product are both faultless. The team were friendly and professional, delivered on time and responded quickly to a couple of concerns I had. The fitter Ramonas did a fabulous job and left my home spotless. The windows are beautiful and the quality by far exceeds window products I saw from other companies. A big thank you to the whole team. My only regret is that I didn't find them sooner.

I would thoroughly recommend Box Sash, and would definitely use them again. They are a family business that take huge pride in the craftsmanship of their products, and as a result make exquisite windows. It has been a pleasure dealing with them, and they have been passionate and courteous and helpful to us at all times. It is rare to come across such quality and professionalism.

I was very impressed with the job London Box Sash windows did from start to finish. Jack the pre-sales representative was very thorough and was able to tailor the requirements to meet our needs. He came armed to our first meeting with an example window which gave us a really good idea of what to expect from the finished product. The payment milestones are practical and fair which ensures you don’t pay the balance until your happy with the job that's been done. Andy, the fitter was very friendly, tidy and efficient and completed the work in good time. Overall I’m really pleased with the windows and so are my neighbours as I’ve had a few comments already!! Thanks again.

We have just had our front bay windows replaced upstairs and down. The new windows match perfectly the original Edwardian style. The estimate was competitively priced and the whole process went smoothly. Andy, the fitter, was excellent and finished the work well on time. He finished off the work meticulously and furniture was protected from dust and dirt; he cleaned up each evening and we quickly were able to put back curtains and furniture. I have no hesitation in recommending them.

From the point of quotation, through to the final fitting, London Box Sash were excellent in all of their work. Jack and Patrick were communicative, and swift in their quotation and surveying, and when they arrived, the windows fitted seamlessly and in the given timetable. The level of tidiness of the install team was exceptional, and you really did not know they had been in each day. We had a couple of specific requests for the windows, that they followed perfectly, and have maximised the light and space in our small house to perfection. Many of our neighbours have asked where we got the windows, and I have no hesitation in recommending London Box Sash to anyone. As a Project Manager for a fit out company, I am exceptionally fussy about finish, and I could not find a fault in the installation of any kind.

We have just had 7 box sash windows installed by London Box Sash. We want to say we are absolutely delighted with the work they have carried out for us. Everything from the initial survey, where they sat down with us to really get to know what it was we wanted, right through to the final installation they have been a pleasure to deal with. We opted for their Premium option sash windows, which although it wasn’t the cheapest quotation we received, we felt it definitely represented the best value for money. We would like to thank Patrick, Jack, Judith and the rest of the team for their hard work and we will certainly be recommending London Box Sash Windows to family friends in the future. 10/10

Our new bay windows are fantastic quality and look great. Everything went smoothly, from the initial consultation right through to the installation. The job was completed quickly and efficiently and the fitter (Ramunas) was polite, professional and very tidy. The improvement in terms of noise, heat insulation and the general appearance of the windows is huge. Thanks London Box Sash!

I would totally recommend London Box Sash - everything from the initial sales process, through to survey and fitting has been fantastic. We have just had more than ten new windows fitted and I am so pleased that we chose this company to do the job. In many ways it was an easy decision as although we spoke to a few others, London Box Sash stood out for us - Jack took us through his sample window in detail one Saturday morning and we could see what a great quality product it was. Once fitted, they looked great - even my builder has said that they are top quality windows (and he sees a lot of houses!) Thanks to all of the team at London Box Sash!
