London Box Sash Windows Ltd

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.
