  • 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.

  • 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.
