London Box Sash Windows Ltd

I was extremely happy with the quality of windows from this company. Also the client service was top of the line as well. The fitter that was sent, Andrei, was professional, conscientious and attentive to detail. Upon leaving he made sure that the job was done properly and that I was happy with the finished product. He ensured that the flat was as clean and tidy as when he'd arrived. I would definitely recommend this company!!

Great quality products at a competitive price and superior client service: Patrick and his team were super helpful in accommodating my needs and fit the overall installation within the timetable of a larger refurbishment process. Very neat and precise fitting with great attention to details. I'll use them again.

London Box Sash Windows installed 4 of their Premium box sash windows on the front elevation of our property. We are absolutely delighted with the new windows that were installed by Andy at the end of last week. They are a great match and the service they provided has been excellent. They have done a marvellous job and having had so many workmen here over the last 18 months I have to say I have not seen anyone work as hard. they worked constantly, never on their phones, polite and really taking pride in the windows they fitted with excellent finishing. My only regret is that we did use them the first time we had windows replaced.......

My wife and I selected London Box Sash to replace our boxes and sashes after getting quotes and assessing the product from 6 window companies including Everest, Ventrolla, Natural Windows and Original Box Sash Windows. Some companies quoted higher prices for just refurbing our sash windows! The quality of their product is outstanding and they were the only company that came with a demo model when quoting so we could see the final product. The box and windows are made from accoya wood (better than standard hardwoods) and they can even put drain holes in the windows to stop the possibility of condensation building up between the double glazed panes of glass (this is an option). When the fitters came they were super careful not to damage or dirty our house by protecting carpets with a sticky plastic protector and placing boards to protect our wooden floor. They also fitted a plastic sheet from floor to ceiling to enclose their workspace to minimise dust spreading. The guys were a pleasure to have in the house and they had a fantastic work ethic. They arrived at 0730 and worked all the way through to 1830 every day for 4 days to get the 7 windows fitted. Now that they're fitted we're considering getting the back of house windows replaced too. The house is warmer (no draughts), the street noise is reduced and the outside of our house no longer look the Adams Family house :-) As I'm sure you can tell we are super happy and highly recommend London Box Sash to friends.

We're delighted with our new windows and doors - and very pleased to be able to recommend London Box Sash. We moved into a new house last year. It's an Edwardian, period-style property and came complete with wooden sashes and wooden french doors in the lounge and the kitchen/diner. They looked lovely but they weren't very warm in the winter... We got half a dozen quotes and explored various options - from restoration through to outright replacement. We went for LBS because we thought that they represented the best value all round; the difference in cost between partial restoration and full replacement was much less than we expected - and we/I were attracted by the reduced need to repaint! We had both sets of french doors, and box sashes replaced, and we're really pleased with the end result. The new windows/doors match the existing style - but are much, much warmer (even though I've not yet managed to rehang the curtains). The installation and fitting was exceptional - we had the work done in December but the disruption and discomfort was kept to a minimum, and the quality of the finishing and detailing was outstanding. The care and attention to detail was second to none, and much, much better than any other tradesmen we've used. We hope to replace more of our windows in due course - and would have no hesitation in recommending LBS to friends and family. Great product and a great firm.
