London Box Sash Windows Ltd

We were very impressed by the initial visit and careful survey to ensure we got exactly the right product for our needs. There was no hard sell. The installer was brilliant: prompt, careful of our house and carried out a good job in an amazingly short time. We are delighted with the results - not the cheapest deal we were offered but absolutely excellent quality.

Jack and the team were a pleasure to work with from start to finish. We had a lot of different companies quote to replace our windows but London Box Sash stood out to be the best as they offered top quality windows for a competitive price, along with great service. Our installer was brilliant and did a fantastic job fitting them whilst making minimum mess and always arrived on time. I would definitely recommend London Box Sash to anyone.

We have recently had all of the Windows at the front of our Victorian mid-terrace replaced and have been delighted with the result. We went with Sashbox because they are a family business and obviously passionate about their product and the service they offer. We had several quotes from other companies but none were as keen to tell you about how their product works and what sets it apart. Attention to detail from start to finish from Jacks sales pitch, to Patrick measuring up and to Jasper on installation. Wouldn't hesitate to recommend them (and are just about to place our second order!). Thank you Sashbox!

I have just had 4 front elevation sash windows replaced, in a Victorian end of terrace house in South East London, by London Box Sash Windows and I am thrilled with them. The whole process from getting tenders, through the survey, administration and installation has been excellent. Jack and Patrick guided me through what was offered and what the installation process was, Judith in the office dealt with the administrative issues promptly and efficiently and Andy the installer was very quick, efficient, informative and left no mess - what more could you want. The quality and finish of the windows is excellent, the difference the windows have made to the warmth and sound in my house is noticeable, and they look so good! I would recommend this friendly, family company with no hesitation.

We have recently had all the windows replaced by Londonboxsash in our Edwardian home in Tooting and are absolutely delighted with the results. The service provided by Jack & Patrick from the initial visit to completion has been fantastic, completely seamless and professional with no problems at all. We were really pleased to use a local family-run business and Jack even gave us a tour of their workshop in Mitcham where we saw the windows being made - really interesting! We were then surprised by the windows being ready earlier than we had expected, and they were then fitted beautifully by Andy & Angelo over just a couple of days with no disruption. The quality and finish of the accoya wooden sash windows is amazing, and they have matched the original detailing and style of windows on our street exactly. We have had plenty of compliments from our neighbours and friends, and would not hesitate to highly recommend Londonboxsash to anyone. Many thanks to the whole team, best wishes Lauren & Kalpesh

Our windows are absolutely stunning and it has completely refreshed the look of our house. We had two bay windows, three single windows and one stained glass window completely redone with London Box Sash (double glazed, toughened, acoustic-glass with new architraves and sash mechanisms) and are extremely satisfied with the results. We have had many neighbours coming by to complement the work and it would be our pleasure to recommend you going forwards. Thank you to Jack, Patrick, Judith, Andy and Angelo for being a first class team. You were completely dedicated to the project, always available to speak to, and it was a true pleasure to have worked with all of you. All the best, Astrid

London Box Sash Windows have recently fitted to my late Victorian house a rear door to the garden, two casement windows and three sash windows. Over the years, I've had two listed houses completely renovated, and in my professional life I have led on the restoration of an important Grade II listed 1896 music school in south east London. I'm struggling to think of a more positive experience with any supplier or service company than I've had with Jack and Patrick Ellis, whose product line is surely second to none. And I cannot speak too highly for the workmanship of Ramunas, the joiner-fitter they scheduled for this job; his profoundly adept handling of materials, client-facing skills and work ethic brought out the best in what the workshop had custom-crafted for my home, and I am very grateful to the whole team.

We have just had our one hundred year old bedroom windows replaced by London Box Sash Windows. We had several quotes but went with a family run business. From Jack arriving with samples of a beautiful product designed by his father and Patrick coming to do the survey ,we were impressed. Then Andy and Angelo fitted the three Windows over a three day period and were excellent. Very clean and tidy, extremely helpful to me when my husband was away ,helping me to put furniture back, above and beyond the call of duty. A great firm, great staff, already having quote for another window .

From beginning to end the entire process was seamless and professionally handled. Jack's initial presentation was clear, comprehensive and without any pressure to proceed with an order confirmation. The detailed comparative illustrations and support material soon followed and again were clear and easy to understand. The most impressive part of all was the actual installation of the windows by Ramunas who completed the work with the minimum of disruption or mess. We are delighted with the outcome and happily recommend London Box Sash Windows to anyone considering replacement windows. David & Sue Dixon-Smith August 2016

We got several different quotes for replacing the windows in our 1930s semi detached. Jack and Patrick were recommended to us and were a head a shoulders above the rest in their customer service. Came to see us straight away and were happy to spend time working out solutions and making suggestions. Andy and Angelo came to fit the windows and did a great job. Arrived on time, worked really hard, polite, friendly, explained stuff and cleaned up after themselves each day. I really feel like they all cared about the outcome for me, the customer. The windows make such a difference and look amazing.
