Fantastic service and beautiful windows

We asked London Box Sash Windows to replace all the windows in our Victorian terrace house in London. Jack, Patrick and the team were incredibly knowledgeable and spent time talking us through our options, explaining the history of the business as well as the specifications for the windows. The windows themselves are beautifully crafted and finished, operate very smoothly and feel incredibly secure. They have been complimented by many people. The glass used in the bathroom window is particularly special and in-keeping with the age of the property. Installation was efficient and took place well within the original schedule we had anticipated. We had recently replastered and no damage was caused to the new plasterwork. We had regular email and phone communication with the team throughout the process who were on hand to answer all our questions. We are delighted with the windows and with the service provided. We were pleased to be able to support a local family business. They come highly recommended.

I couldn't be happier with my new sash windows and French doors. The quality of the design, workmanship and materials is excellent, the communication and general service are also just as good. It's always nice to use a family company too - Jack and Patrick run a professional and friendly outfit. They took considerable time to help me design really stunning French doors and were really flexible when it came to installation requirements. I'm kicking myself that I didn't find this company earlier - I used an alternative sash window specialist company to fit some windows just after moving, the quality is just not nearly as good despite them being more expensive.

We have just had seven windows replaced, including a bay window, in our (1906 built) house by London Box Sash Windows Ltd .We are absolutely thrilled with the finished work. Simply cannot fault a single aspect! The quality and finish is stunning and has greatly improved the curb appeal and heat efficiency etc of our property. However, what has been most impressive is the professionalism of everyone we dealt with. Jack and Patrick have clearly picked up the mantle from their Father and continue to deliver a top quality product and exceptional service for every customer. The administrative side was straightforward and excellently handled by Judith. Angelo and Raf are the most outstanding workmen we have ever had in our house! Angelo walked in with a small tool box on the first day, proceeded to cover every surface and carpet with protective sheets. Then brought in a whole workshop of tools and equipment and then worked very hard and non-stop with an attitude of pride and concern for his work. On the last day, he walked out with the same small toolbox and no-one would ever be able to tell that they had been here! - apart from the wonderful windows they installed! It was a total pleasure to meet them both and a joy to have them working in our house. We have no hesitation in recommending London Box Sash Windows Ltd.

I recently used London Box Sash Windows to replace the bay windows and French doors at my Victorian-age property. Having received quotes from a number of local & nationwide firms, I am delighted that I went for LBSW. From the initial consultation through to final installation, every one I dealt with was extremely professional, personable and highly-skilled. They take real pride in their work and it shows. I would recommend them without any hesitation.

We used London Box Sash Windows on our renovation and they were fantastic. Punctual, efficient, clean, courteous and friendly. They were always willing to help and assist and go beyond to deliver a quality product and service. We were let down by other trades a lot during our renovation but London Box Sash were fantastic to work with - never had a problem. I am so glad that I went with them over their competitors as they have really looked after us and treated our job with utmost attention. I will definitely use them again and recommend them to anyone looking for a premium product. I have not used the other companies out there but I doubt they will be able to deliver the same service.

We replaced all seven windows in our house, one of which was a bay window. We bought the 'top of the line' as we do not want to replace them again. The windows operate perfectly, the noise reduction is marked (and this was replacing secondary glazing). The fittings operate smoothly and the windows look beautiful. The workmanship and quality cannot be faulted and the work was carried out efficiently and on time. I wish everybody one deals with was like this. Great job.

I would like to take this opportunity to Thank everyone at LBSW. The level of service and professionalism I received throughout the process was exemplary. Jack at the initial sales consultation, Patrick for the survey and finally the most accommodating, friendly skilled craftsman in Audi. We are so pleased with transformation the windows have made to our property. If you are in the process of researching what company to appoint for your windows/Doors like I was - I spoke to most of them and we could not have had a better result. LBSW are a local family business and this shows throughout in their passion and personal approach to the full process.

London Box Sash overall did an excellent job in my opinion. Their billing process and costs estimates were spot on and thoroughly discussed in advance. The guys who came to measure up and undertake the fitting were also bang on time, quick, helpful and polite, and we're happy to chat through minor practical issues and even suggestions on other things (window security) etc while there. Overall, money well spent and I'd definitely use them in future myself on another possible job in the house, and recommend them to others.

We are so impressed with London Box Sash Windows installation of a new sash window for us, the window itself is stunning and dealing with everyone at the company has been a pleasure. We got the recommendation for London Box Sash Windows from our neighbourhood Nextdoor network and not only were they the most friendly, polite, pragmatic and responsive, but also the most reasonably priced of a number of companies we contacted. We were impressed from the initial consultation with Jack who carefully checked what we wanted and offered a range of options, through the technical check by his brother Patrick and finally a superb installation by Anjelo, with support at all stages from Judith in the office. We just had the one window installed but Jack was very flexible to arrange this just how we wanted, both in terms of price and how quickly the install could be arranged, with this being much earlier than the competition, four months so in one case. We totally recommend London Box Sash Windows and won’t hesitate to use them again.

Highest attention to detail and quality from beginning to end

We cannot find a single fault in any of our dealings with London Box Sash Windows. The first meeting with Jake, who came to measure up and give us a quote, was very impressive. There was no heavy selling and he explained everything in very clear and easy to understand detail. My wife and I were very impressed by the full sized display sash window he brought with him to explain all the features. The fitters, Ramanus and Audrius, turned up on the dot every day ( beware the early starts!!) and never stopped working until they left at the end of the day. They left absolutely no mess so all we had to do each evening was to put the furniture back. We were slightly sceptical when told that there would be little damage to any internal decoration, and so were amazed at how little re-touching was needed to paintwork around the windows. The windows are brilliant and I’m actually looking forward to a cold winter as I know we will be draft-free and will have a smaller heating bill!
