Fantastic work by London Bow Sash

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.

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!

We recently had the sash window at the front of our cottage replaced by London Box Sash Windows and it looks fantastic. The quality of the frame is excellent. The service we've received throughout was great and the fitting was efficient and hassle free.

I would highly recommend London Box Sash windows. From the initial detailed consultation with Jack, the comprehensive survey with Patrick, speaking to Judith in the office, to Mark and Angelo who made the installation straight forward and easy, this is a family company who obviously take pride in their product and the high quality service they provide. The four upstairs windows, French door and large ground floor bay window they installed not only look fantastic but have already made such a difference to the warmth in our house. Although a few issues did arise with the French doors, these were dealt with quickly, professionally and to our complete satisfaction. Both Mark and Angelo were extremely considerate around our newly decorated property which we much appreciated. I would have no hesitation in recommending London Box Sash and intend to use them again in the future to complete the rest of my windows. Thank you so much Jack, Patrick and all the team at London Box Sash.

Really impressed. From the initial quote to the final installation London Box Sash were flawless. We had a large bay window in our London flat and are delighted with the final product. Has hugely improved the sound and heat insulation, not to mention looks amazing. We had quotes from a number of competitors and are delighted we went with London Box Sash. Would 100% recommend.

The entire process was simple. The whole team were very professional, good communicators and totally reliable. The end product is fantastic. My neighbours commented on how good the fitters were and are now very envious of my beautiful window. Great family company. Highly recommend them.

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.
