London Box Sash Windows Ltd

This is the second time I have purchased windows from London Box Sash and both times the experience has been excellent. From the initial appointment, to timing of the quote, survey, communication from the office and finally the installation, everything was handled efficiently and professionally by all the people I interacted with. The installer completed the job a day ahead of schedule and left everything tidy. The quality of the windows is outstanding, and I would happily recommend them to friends and neighbours.

Patrick, Jack and the entire team were simply fantastic. From the off they were incredibly helpful and this carried through the fitting and now 5 years later their level of service is simply unparalleled to any other company I have dealt with. The quality of the work is fantastic and the sash windows are marvellous. We often get compliments from walkers passing by. I cannot recommend London Box Sash Windows more highly. You will be in safe hands with a wonderful family run team.

This is the second time I have used this company and my experience was just as good. The quality and finish on the bedroom door and windows I had installed was perfect, and as before the installation was well organized, painless, and quick. The company is a family style business and they are extra friendly. Also, nice to know manufacturing is done locally. 109% recommend.

We have had three beautiful sash windows made and installed by this exceptional company! From beginning to end their professionalism was five star. Simon who first came to the house and talked us through the process and showed us what we could have was so personable, intelligent, and passionate about the product, the service, the company and what he does. We tend to ask a lot of questions and he was so patient in his answering everything. Even the various phone calls after his visit. Solid. Harry, the surveyor was similar. Cheerful, thorough and willing to answer all the detailed questions. Anjelo and Rafal our two installers, were a delight! So punctual, friendly, hardworking, immaculate in the clean up. It was a lovely day having them here! And in the office, Judith and Jack once again helpful, efficient, and always cheerful. And how nice to be able to phone and get a live person who is like that. This family business can very proud of the high quality of product and people that they have brought together. Bravo! Sincerely, from Carol and Philip

From our initial enquiry onwards, every aspect of getting our three new windows went smoothly. The estimator, surveyor and fitter were all caring, polite and efficient (as was the accounts manager who I only spoke to on the phone). Every effort was made to cause as little disruption as possible and protect to our rooms, carpets and furniture before work began. This work proceeded at a pace and by the end of day one (of three) two windows were already fitted. The windows are beautiful, bespoke made in the LBSC. factory but the architraves are cut on site by the fitter so perfectly fit each window. We got cheaper quotes but are so pleased we chose London Box Sash Windows Ltd. The professionalism, care and quality of the windows are brilliant. Thankyou to other Which Trusted Traders reviewers who helped us make the choice.

This is the second time we have used The London Box Sash Company. The first time was about two years ago. On both occasions they did a superb job with the fitting of new very high quality windows. The sound reduction has been remarkable. The property is a rented property and communications between us, the tenants and company and workmen were excellent, with quick and positive responses to any queries. From the survey they were able to give extremely helpful and knowledgeable advice for which we were very grateful. As a result we were able to make informed decisions at our own pace. They are, in fact, a pleasure to deal with. The schedule was adhered to strictly and to everyone's satisfaction. In short, I have no hesitation in highly recommending this excellent firm.

LBSW recently fitted 2 new double glazed box sash windows in our Victorian house. As we live on a busy road we opted for the acoustic glass in the front of the double glazed unit. We can really tell the difference already in terms of sound proofing. The windows are beautifully made. The fitter Andy was very professional. He kept everything clean and tidy and went the extra mile in making sure the details were right. All in all, a smooth experience from start to finish with good communication all along. I highly recommend.

London Box Sash Windows just completed the installation of our new, double glazed windows across our mid-terraced Victorian house. We couldn't be happier with the experience, from start to finish. Jake took a lot of time during the initial consultation, explaining the options available and impact on costs. We had four quotes in the end, roughly in the same price range and decided to go with LBSW due to their professionalism and responsiveness. Harry did the technical inspection pre-installation and Judith kept us updated throughout the process. At the scheduled day of installation, Audris arrived punctually (on the minute!) and his and David's work was spotless. They both worked extremely hard, precise and left every room they worked in tidy (we didn't have to do any cleaning ourselves!). Within a week, all our windows were done, in line with the promised timeline. We could really trust the team and go about our lives and just leave them with a key, which is a great feeling. Also, there was much less redecoration needed than we feared, thanks to the team's careful way of working. Choosing a firm to work with for new windows was a big decision for us, and I can only recommend LSBW. Our house is much warmer, quieter and with no more annoying draughts, we don't regret the investment for a second.

For some time we have been working towards replacing some sash windows in our large mid-Victorian semi-detached house so as to reduce draft, make some rooms warmer, make window opening easier and hopefully safe some energy cost. After visits by several companies, it was clear from the start that LBS offered a more personalised service and listened more carefully to what we actually wanted. They were the only company to offer sash-only replacement and the only one to point out that full frame replacement would cause problems where the window frame was integrated with shutters and a plaster cornice. All the pre-installation contact was great, with a very detailed on-site discussion of all the different options. A very detailed specification/estimate was sent for checking, and then a second survey by the fitting expert to iron out the last few potential glitches. The two fitters were brilliant, changing 8 windows in 4 days, arriving promptly for a 7.30am start, and meticulously clearing up dust and rubbish to leave the house in a very good state each day. On the final evening we immediately noticed the reduction in noise and draught, and the increased warmth. We would not hesitate to use LBS again and to recommend them to others. High quality full replacement of sash windows is not cheap, but we feel that we have installed an excellent product that has greatly enhanced the comfort of our home, that will last for many years, and that has increased its eventual sale value.

We have used London Box Sash 4 times - and their service levels have been superb each time. Great product, installed on time, everything left tidy. But best of all, our house is warmer and quieter thanks to the double glazing.
