One customer said:

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.

Louise Norman

I am very satisfied with both the products and service provided by London Box Sash Windows. I was reassured by Murray’s knowledge and experience and he was helpful and patient when I was working out what I wanted. He listened, and there was no “hard sell”. Harry did the survey and Anjelo and Rafal the installation. They were all punctual and courteous. The installation was carried out quickly and efficiently, and Anjelo and Rafal took care with my property and tidied up after themselves. The aftersales care provided by Murray was excellent. Nothing seemed to be too much trouble. Having windows replaced is not a cheap option and involves a fair amount of upheaval, but I felt throughout the process that I could trust LBSW to provide value for money and make it as smooth as possible. I am very pleased with the end result. My new bay window looks great and is totally in keeping with the period of my property, including the “swept” heads. I immediately started to feel the benefits of having double-glazing in terms of heat retention, no draughts and noise reduction. I will also benefit from the improved security and low maintenance it offers. I would not hesitate to recommend London Box Sash Windows.

Fritha Hookway

So happy with the whole experience with London Box Sash. Our new windows look amazing. The whole process was very thorough, competitive in price and really quick for install – which was a nice surprise as the lead time was halved from what we’d thought it might be. The team were also exceptionally helpful when one of the old windows were were planning to replace was severely damaged during a storm. They came to board it up free of charge in the interim while the new one was still being built. Simon in particular was really helpful – a huge thank you to the whole team.

Joe Philp

A fantastic job. The end result is brilliant and a big improvement in terms of sound and thermal insulation. The team went above and beyond, taking time to understand our requirements and coming up with creative solutions. They were helpful and responsive throughout the process and the job was done quickly, carefully and meticulously – despite a last-minute adjustment that had to be made during the replacement. We felt in very safe hands and trusted the team completely – I wouldn’t hesitate to recommend.

This is the second time we have used London Box Sash to replace wooden sash windows in our conservation-area property. The quality of the windows is excellent. The team at London Box Sash, both the people in the office and the installers who come out to fit the windows, are an absolute pleasure to do business with. The installation team left my house spotless. A couple of small snagging items were dealt with within days. Highly recommended.

Phil Feddon

This is the second time we’ve used London Box Sash in the last 2-3 years. Once to replace all the windows at the front and recently to replace windows at the rear.Both times the service has been excellent all the way from the office staff to the operatives on site. Smooth operators, clean and efficient I have no hesitation in highly recommending the company.

Matthew Carter

I’ve had 4 windows done by London Box Sash Windows now and every time the entire process from quote to installation is so smooth and stress free that I never bother to contact anyone else.The final windows are great quality and beautiful to look at and the work is always done in the timeframe agreed with the installations always carried out by very friendly and professional people.

Jody Torode

We are a returning customer of London box sash windows. Initially we went with them as they were the cheapest quotes however when we needed other windows to be replaced we didn’t approach any other company, we were so happy with the job they did the first time we wanted to use them again.I was fully informed about what to expect, given clear time scales and they were super helpful in providing information to support our planning application.There was a slight hiccup with the window not being quite right however this was resolved with no issue at all, another window was made and fitted within a few weeks.The fitters are really friendly, work hard and clean. They do an excellent job and I have no complaints what so ever!The whole service from start to finish has been really positive.

Jalon Quinn

All round excellent service from start to finish. Polite, efficient, took care with other parts of the property and cleaned up better than I could have done. Not the cheapest but worth the investment.
