Designed for dreamers, by dreamers
We’ve always had a vision. Since the beginning, we’ve been as passionate about creating a feeling as we are about our products themselves. We dreamed of inspiring warmth and togetherness, of bringing a sense of tranquility and safety to an indoor environment and for people to step back and enjoy. Our vision today? It’s the same as it ever was. We want our windows and doors to truly change the way people live and help everyone achieve their own space of calm right there in their own home. Dream big, and we’ll frame your world.
Danish foundations. International impact.
Every year we craft and deliver over 350,000 windows for new build and renovation projects around the world, with each one demonstrating the iconic Danish design and attention to detail that we’re known for. We’re proud to be part of the DOVISTA Group, comprised a number of Europe’s leading window and door companies. Owned by VKR Holding, DOVISTA strives to bring air and light into the lives of people everywhere, every day – and is a mark of the quality that permeates everything we do.
Built to last, in every sense
We don’t do what we do to create something short-lived. Our windows and doors are built to last; durable, high-performance products to be enjoyed for decades. The same goes for the relationships we build, not only with our customers but everyone we work with, from installers to distributors to sales teams. Our approach sparks longevity and a trusted connection – and that’s what makes us different.
What our customers say
From the first moment when Arthur came round to advise, measure-up and quote for the job we felt we were in good hands. And his team of installers provided the best service. I always think that the best test is if something needs further attention and in this case they returned promptly to fix a small issue and nothing was too much trouble. Our new doors have transformed the back of our house and we highly recommend this company for work of the highest quality. Thank you Arthur and team!
They have fitted a new back door, front door and front room and kitchen window. Great service, price and quality. We are very happy!
We got our back and front doors replaced by E&A Windows and we couldn't be happier with the job they did. Erez was so helpful as took the time to come to our home to give us a quote, explaining all our options thoroughly and clearly without being pressuring in the slightest. The quality of both doors was fantastic and Adrian’s installation was fast and completed to a very high standard. He was also very helpful. We would highly recommend E&A Windows and will definitely use them again for any future double glazing needs. Thanks so much!
Very professional service! During my initial consultation, I was fortunate enough to deal with the owner of the company. He visited my property and spent a few hours talking me through design options and his recommendations. His recommendations were very insightful and ensured my build looked elegant and modern while retaining the functionality required for an active family of 4. The build process was equally professional with the construction team arriving when they said, treating my property with respect and cleaning up after they finished each day...something not often done by today's tradesmen. I've recommend this company to my parents.
I have just had new windows installed by E&A Windows and I must say I was very impressed. Arthur the owner of the company was so helpful and supportive throughout the process. I don't know much about windows so was skeptical at first, but I felt at ease very quickly. The guys who came to fit the windows (John, Christie and Peter) were absolute legends. They were extremely friendly and so so helpful, and the respect they gave me, my elderly parents and our home was exceptional. They took care of our home as if it was their own. I have never come across such professionals, not only did they do a fantastic job , but they went well beyond, seemed like nothing was impossible. They were with us only for 3 days but my parents were actually sad to see them go. I would highly recommend them to anyone looking to fit new windows.
