Jake provided a great consultation and really listened to my requirements. He was confident, yet gentle with his approach and so knowledgable. I received multiple quotes from providers which honestly felt like a waste of time, as they didn’t seem to listen to my needs of wanting timber only. London Box Sash Windows stood out among them all, especially for their expertise and care in period properties. Really competitive pricing as well! Cannot wait to use and would highly recommend!

West Brompton Accoya sash window company

Our Accoya sash windows represent the pinnacle of custom craftsmanship, blending elegant design with exceptional durability. These windows enhance a property’s aesthetic appeal and offer smooth operation and impressive thermal efficiency, making them a valuable addition to any home.

Accoya wood is a top choice for sash windows due to its unique properties and eco-friendly production. The wood undergoes an advanced acetylation process, altering its structure at the molecular level to ensure unparalleled stability and durability. Accoya sash windows withstand London’s variable climate for decades without cracking, swelling, or shrinking. Its sustainable origins and non-toxic production methods make Accoya an environmentally responsible choice, combining strength and beauty with ecological goodwill.

While oak is admired for its classic beauty and durability, Accoya surpasses it in several ways. Thanks to its innovative treatment, Accoya resists rot, decay, and insect damage more effectively. It also offers superior dimensional stability, reducing swelling and contraction over time. Additionally, Accoya’s sustainability credentials, including the use of ethically sourced materials and non-toxic methods, make it a cutting-edge option for eco-conscious homeowners.

One customer explained:

Absolutely brilliant windows. We looked around the competitors but London Box Sash made windows that looked closest to our originals. Key thing to note in my photos is that the weather seals are white and not black like most competitors. Their customer service and quality professionalism was top notch. Thank you.

I recently had a new sash window fitted in my living room and London Box Sash could not have been more helpful.Jake was absolutely brilliant and talked me through all the options and helped me choose what was right for me. The ordering process was simple and the fiting was carried out in one day and I am so happy with the finish.Would definitely recommend – the care and attention to detail is wonderful.Thank you!

Thrilled with our 3 new box sash windows. The quality of the windows is excellent and worth every penny. I thought the price was very fair compared to other quotes I received given the quality of the wood that is used, the length of the guarantees and the ease of the company to deal with. The process from start to end has been seamless. Everyone we interacted with was superbly knowledgeable, responsive and helpful – from Harry, the sales person who helped explain all the design considerations and options very clearly, Judith in the office helping getting us booked in and Andy, the fitter. Andy consulted us on any bits where needed explaining clearly the decision that was needed and his work was to an excellent standard and he was very clean and tidy and respectful of our home. He also kindly made the suggestion to ask our decorator to angle the external sills as they were flat so that the water runs off which would help avoid any damp issues and improve longevity. His wealth of experience was very obvious and I was grateful for him sharing these pointers and discussing directly with my decorator – it’s something that would never have crossed my mind without his tip. I thoroughly recommend!

Robert Purdew

Can’t recommend enough.The windows installed seem like they’re a really high quality product. Very good customer service from end to end. They do a really thorough consultation & respond quickly to calls and emails. The day of the installation was easy and the guys who installed were quick and left no dust or mess. Followed up at the end via text, email and a call to check I was happy with the product – highly rate this approach.

Christine Haight

I found London Box Sash Windows through an online search.With my previous company, I did not get any Fensa certificate and the quality of the wood was inferior to the one used by LBSW for similar prices.They offer a 10% discount for their Standby Schedule Saving which gives very good notice for the client as well. I am very pleased with my double glazed window and the people at LBSW are very helpful.Christine Haight

Judy Carlisle
