London Box Sash Windows Ltd

Love the new windows. Very pleasant and professional team to deal with. Fitter was very efficient and as tidy as we could have hoped for.

I could not be more pleased with my new windows, or with the service I received. Jack and Patrick were absolutely lovely to deal with, gave me no pressure to proceed and were genuinely interested in solving the terrible condensation I was experiencing on my old windows. My fitter was called Audi, and he worked really hard to get my new windows in, paint them and put everything back in place. It's been a huge relief to get the job done, it was so straightforward and now I have some beautiful, functioning windows that look fantastic and keep my house warm. Absolutely fabulous!

This was an extraordinarily satisfying process. Patrick and Jack were very helpful and thorough in the planning stage for replacing three of our sash windows. The design was excellent. The quality of the windows and woodwork was perfect. As for Anjelo our fitter… he was so considerate, courteous and such a good worker. Boy did he work long hours to make sure everything was perfect as well. This is a genuine, heartfelt 100% recommendation. We look forward to booking you again!

We recently had the sash window at the front of our cottage replaced by London Box Sash Windows and it looks fantastic. The quality of the frame is excellent. The service we've received throughout was great and the fitting was efficient and hassle free.

I would highly recommend London Box Sash windows. From the initial detailed consultation with Jack, the comprehensive survey with Patrick, speaking to Judith in the office, to Mark and Angelo who made the installation straight forward and easy, this is a family company who obviously take pride in their product and the high quality service they provide. The four upstairs windows, French door and large ground floor bay window they installed not only look fantastic but have already made such a difference to the warmth in our house. Although a few issues did arise with the French doors, these were dealt with quickly, professionally and to our complete satisfaction. Both Mark and Angelo were extremely considerate around our newly decorated property which we much appreciated. I would have no hesitation in recommending London Box Sash and intend to use them again in the future to complete the rest of my windows. Thank you so much Jack, Patrick and all the team at London Box Sash.

Really impressed. From the initial quote to the final installation London Box Sash were flawless. We had a large bay window in our London flat and are delighted with the final product. Has hugely improved the sound and heat insulation, not to mention looks amazing. We had quotes from a number of competitors and are delighted we went with London Box Sash. Would 100% recommend.

We’ve just had all our Victorian sash windows replaced - 9 windows, two of which are large bays. A major piece of work in a busy household of six people ranging in age from 76 to six years old. London Box Sash Windows could not have been more accommodating and helpful. A small glitch at the start of the work was dealt with immediately and professionally. The window fitters could not have been more friendly and helpful. The end result is excellent and completely in keeping with the Victorian features of the house. What could have been a messy and very disruptive experience was warm and professional with a high quality end product and all within the time frame. I thoroughly recommend this company.

The initial consultation with Jack was great. He was polite, highly knowledgeable, very informative and not at all pushy. He offered various options for the wood/glass type to the final design. Although by no means the cheapest, both the high quality of the product and their experience means they are good value. The fitter, Andy, worked incredibly hard and obviously was highly experienced. He was also friendly and took pride in his work. The finished product looks great. I was also surprised how tidy everywhere was when Andy finished. I highly recommend London Box Sash.

We have had seven windows and a single patio door replaced by London Box Sash over the last four months, in two batches. We would recommend them without reservation to anyone who wants to pay a bit extra for premium quality. The range of choices available is clearly explained with no pressure to buy any particular product, and every question we had was factually answered to our satisfaction. Booking fitting dates was stress-free and flexible, and if you can go with their standby schedule you can get a bit of a discount. The installation was professionally done, and most important of all, the quality of the product is lovely - with just the right combination of traditional appearance and modern technology (sound proofing, heat insulation, anti-condensation, long-lasting treated wood that doesn't expand etc), tailored to your particular choices. The people we dealt with (Jack, Patrick and Judith) were all pleasant and efficient, and it is lovely to see that a family-run company can compete successfully in this market. They deserve to flourish, and we thoroughly recommend them.

We replaced all the windows of our property with London Box Sash Windows and they not only provided an excellent product of superb quality but an outstanding customer service too. They were very flexible with our timings. Turned up on time every morning and left the property spotless each day and completed the job on time. Since the windows were fitted we have received various great and positive comments from neighbours and friends about them! We would definitely recommend them and with no doubt would hire them again. A fantastic team!

I had four replacement sash windows fitted in the autumn having had others replaced previously by another company. There really is no comparison - both in the quality of the product and the customer service. All the staff at London Box Sash Windows are friendly, reliable and do a great job. The guys that came and fitted the windows were always on time, were respectful of my home and cleared up very well. The windows have made a real difference to the warmth of my home over the winter. I have no hesitation in recommending this company.

We could not rate London Box Sash highly enough. No hard sell, offer a high-quality product that you pay a little more for (as opposed to refurbishing existing windows, which was our original preference) but in our view, well worth the investment. Jack and Patrick clearly love what they do and made the whole experience a pleasure. They understood that new windows were a real investment for us and at no point did we ever feel we were given pressured into making a decision, and we were very patient with answering questions and their explanations. Our windows look beautiful and operate wonderfully. The whole process was great, the initial decision on which specification to installation. We were kept informed on lead times and it was never difficult to reach out and have questions answered. Andy, our fitter, was efficient, took care with the install, sealed off the rooms properly so the dust in the rest of the house was kept to a minimum. He takes real pride in his work and it really shows through in the windows. He discovered problems with the lintel above the bay window, but took initiative to resolve rather than turning it into an issue. Couldn't recommend highly enough.

I had 4x new sash windows fitted at my flat in Balham and I can't speak highly enough about my experience with London Box Sash. From start to finish they were true professionals. Patrick and Jack did a great job measuring up and talking me through the various options, and I never felt under pressure. When it was time for the installation both their fitters (Andy & Anjelo) were first class. They protected the carpet in the entire communal hallway, dust-sheeted everywhere and when they left the flat was spotless. Great guys and never thought twice about handing them the keys. The product itself is perfect - really nicely weighted sash movement, great paint finish and I'm told the Accoya wood is incredibly durable. Patrick told me that cleaning the windows would be easy, because of the texture and quality of the Accoya, all I would need was a good quality shammy and any stains would come off with tap water. With that quality obviously comes a price, and as Jack will tell you these aren't cheap windows. Having lived with them for the last four months, the quality fully justifies the price. Ipso facto; trust received, responsibility given and taken. All in all, I wouldn't hesitate to recommend London Box Sash and their windows, which prove that a good idea, is a good idea forever.

We had five windows replaced in three rooms at the back of the house. Unfortunately we do not have sash windows at the front. The whole process was completely trouble-free with Jack and Patrick gaining our confidence with their straightforward, no hard-sell approach. Judith responded promptly and Andy was great. We were away for the first couple of days so missed all the real disruption. When we came home on the third day, Andy was finishing off round the edges of the frames. We wanted the windows to be as near to the originals as possible and they are. The workmanship looks superb and-it may be our imagination -the house feels warmer already. We have no draughts and no armies of ladybirds coming in to die on the carpet! We went on the Which? recommendations and would endorse them all. The windows are not as cheap as UPVC ones but so much more attractive.

From start to finish our experience with London Box Sash Windows has been excellent and I would thoroughly recommend them. Having met with a number of providers they were the most professional and no hard sell. Throughout Jack, Patrick and Judith were always quick to reply, very knowledgeable and worked with our builder to make everything come together. Andy (the fitter) was a pleasure to have in the house, put in the hours to get it all finished and left the house so clean and tidy. The windows are fantastic, they look great and have given us much warmer rooms. The gift of a bag of log burning blocks from the factory was the icing on the cake from a genuinely lovely company with a brilliant product.

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
