London Box Sash Windows Ltd

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.
