ATTENTION TO DETAIL
Our replacement Slimline Aluminium Windows and Doors range is designed to replicate the appearance of traditional steel windows and “crittal” style windows. Beautifully designed with close attention to detail ensures that you would be hard pressed to notice the difference from steel windows and our aluminium replicas.

The Window Sanctuary supplied and installed a window in the current house we are restoring.
We were extremely happy with the service and quality of the window. Would definitely recommend this company for your period windows.

August 20, 2021 - The Window Sanctuary supplied and installed our patio doors. We are extremely happy with the service they provided and couldn’t be happier with how the doors have turned out. They are exactly the look and quality that we were after.

May 21, 2021 - The team at The Window Sanctuary have been a delight to work with. They have given us really personal customer service, ensuring that every final detail works for us and our build and have listened to what is important to us (happy to be flex when we change our minds!). Quick to respond and offering a really consultative approach, alongside good value for high quality products, I would strongly recommend their service. I was really specific in what I wanted for bifold doors, wanting time achieve that much coveted Crittall appearance and they’ve made this work for us with a good quality option that doesn’t break the bank. What a find!

January 20, 2021 - The team did a great job installing new sash windows in our flat: the wood grain effect on their PVC looks great, they took away our old windows and worked swiftly, on time and on budget to get the new ones fitted. I can definitely recommend them! Thanks!

February 24, 2020 - One year ago we had our windows and doors installed. We are very happy with the product so far. What made me write a review one year later is their amazing customer service. Our door needed adjustment and I asked someone to look at it and fix it. They send an engineer the next day, who came on time and managed to fix it. Very pleased. As it is quite rare these days, companies cut corners and dont look after their clients.
