London Box Sash Windows Ltd

My 1901 house had draughty original sash windows with 2mm glass. I had 11 sash windows and one panel above the front door replaced. Recommended by 3 neighbours whose windows I viewed before contactiing LBSW. After suffering the trauma of hard sell by another company I was relieved by the relaxed but informative response of Jack and Patrick. After they patiently answered all my questions I was aware of each stage of the process. Jack said it would take 10-14 days and it actually took 8. Andy arrived at 7am every morning and removed and replaced 3 windows on the first day. Furniture movement was minimal and well protected. All rubbish was removed at the end of each day and the room left tidy and dust free. The bathroom window was tricky to negotiate around a basin and tiling but each stage was discussed . Andy, mindful of my privacy replaced the bathroom roller blind on the day of its fitting , not within his remit but very impressive. My design on the glass panel above the door was agreed with Jack who made every effort to get my sandblasted house number and its placement exactly as requested. Neighbours keep saying how beautiful the windows are and subsequent workmen in the house have said how high the level of workman ship is. One tiny blip with a window was fixed by Jack himself who also took photos. Security is now very efficient with various locks so I feel safe and warm with the house being much quieter. Very happy.

I'm a managing trustee of a religious meeting house and fundraised for years for timber casement double glazing for the front elevation of our building located in a conservation area--so I had to find a windows company that would deliver long term value for us. London Box Sash created and fitted the most beautiful windows for us, and everyone who uses the building is delighted with their beauty and performance (a much quieter and warmer interior). They took responsibility for the entire process, which was a relief to me, and the long guarantee is very reassuring. They were delightful to work with at every stage. I especially appreciate the care the fitters took with protecting the building as they worked. We will use London Box Sash again and I highly recommend them.

Good price and the window they installed for me looks fantastic. Was done in exactly the time suggested and for a competitive price. Everyone was very professional and responsive and the process was extremely easy.

London Box Sash replaced several window casements and two French Doors in my lounge, as well as several casements in the bedroom. The whole service from beginning to end was timely, courteous, and professional. Discussing my different options was not straightforward as I was only replacing casements that needed repairing, and I received good honest advice at this stage. The process from initial consultation to instalment was great, with clear communication at each stage and London Box Sash happy to help me with any details etc. Fitting was also an excellent experience: the workman turned up on time (early in fact!), cracked on with the job, and completed all the work to a very high quality and ahead of schedule. Only one small snagging issue was dealt with straight away and with the minimum of fuss. Would recommend to all without hesitation.

Super happy with the sash windows and the craftsmanship. They made the whole process really easy, windows are superb, and the installation smooth with great attention to detail. Thoroughly recommend.

London Box Sash were commissioned to build and replace the old wooden single glazed sash windows in our old Victorian house. I was torn between trying to give the old ones a few years of life or just getting new ones. After visiting their premises and trying out a sample of what my potential future windows could be, I knew at that point that any doubts i had were gone. The staff were great, helpful and answered all our questions and the final product is something that I marvel at every day. Will see how they fare through the winter but I'm sure that I'm going to have a cosier, draft free one. Hats off to Andy for such a great install, super tidy and knows his stuff. Would certainly recommend!

I was impressed with the London Box sash window from the initial contact. The surveys were carried out by approachable and personable people who listened carefully to our needs. The price was competitive when compared to similar companies. The installation team showed amazing attention to detailed working with the minimum of disruption taking great care to minimise mess. I was consulted by them at every stage of the installation. The finished widows are excellent. The house is quieter, warmer and looks a lot better. I would strongly recommend the company to anyone looking for a high quality product to enhance their home.

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!
