Stunning new sash windows Wimbledon

Very efficient local team, first to book appointment and good contact from Judith in the office. Very thorough presentation from Jake and ability to offer a discount for speedy installation.Andy installed windows and he was professional & friendly. A very clean and methodical approach.They also have an after service care should anything happen which is very reassuring.I have already recommended them to two friends of mine.

I was very happy with the bespoke casement window they installed in my property. The company also agreed to repair it promptly after a number of years. London box sash install high quality timber windows and seem to care about their customers.

Needed a couple of old aluminium windows replaced with box sashes. Found recommendation for London Box Sash Windows Ltdon Which? Trusted Traders website (where they came top for our local area with over one hundred 5* reviews). Three days after the first phone contact, Jake came to our house to quote for the job. He took his time to take us through the various product options and even brought a sample sash window to demonstrate those options (all without any of the often quite annoying hard selling tactics). The quote price wasn’t cheap but within our expectations, and therefore we decided to go ahead with this company. We were given the option to either go for a scheduled installation date 10 to 12 weeks into the future or to go on a stand-by list. We opted for stand-by and a week later Harry (installation manager) visited to take the exact measurements for the window production and to reconfirm all the chosen options. About 2 weeks later, we were given an installation date.The actual installation was done by Andy over 2 days (1 day per window). On both days he started work at 7.30am, properly preparing the room with dust sheets and covering all carpets, before even touching his tools. He worked both days non stop until about 4pm. Andy was very pleasant to have in the house. He took the time to explain the details of the installation and patiently answered all of our many questions.The best, however, was the finished product. 2 gorgeous wooden box sash windows that are perfectly balanced, so that you can actually lift the solid and quite heavy sashes with just one finger!I wish that we had used London Box Sash Windows Ltdfor the replacement sash windows at the front of our house, a job which we had done about 6 years ago. Although those were of good quality, they are nowhere close to the ones that we had done just now.Without hesitation, I will recommend London Box Sash Windows Ltd to friends and neighbours and only keep quiet about this great company to the people I don’t like …

I have bought windows from London Box Sash twice now – the service is unmatched. Having had quotes from a series of other providers, LBSW kept coming out on top for me. The quality of the windows is extremely high, and they have made a massive difference to the feel of my home. The double glazing is excellent, and the installation was swift and professional. A huge thanks from a very happy repeat customer.

Outstanding customer service and quality in every aspect and interaction. We ended up replacing all the windows that we could with these guys on the strength of the experience we had with them. Would highly recommend getting a quote from them if you are in the market for windows.

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.

Great company to work with. Trustworthy, honest and efficient work ethic.Thoroughly recommend this company.

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 (although we knew that the payback time against energy cost is long). We had visits from several companies identified with flyers through the door, internet searching and personal recommendation, the latter being for London Box Sash Windows (LBS). 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 (as against the whole window and frame) and were the only company to point out that full frame replacement would cause problems with windows 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 what was wanted, and the different options. LBS helped us create two windows with reproduction Victorian coloured and frosted glass which look fantastic (see attached photo). A very detailed specification and estimate was sent for checking and acceptance, 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. They worked with minimal noise and fuss and were receptive to the large number of checks and queries that always crop up during a large job in your own home. They were not the least put out when our plumber turned up a day earlier than expected to refit some radiators. 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.
