  • 5 star review  Really enjoyed dealing with the Window Sanctuary. The office team are very friendly and courteous and the installation team were good fun and very thorough. The finishing touches were beyond my expectations. We're delighted with our new windows and the enhanced view they provide.

  • 5 star review  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!

  • 5 star review  We had our conservatory doors replaced with by-fold doors by The Window Sanctuary and are very pleased with the results . The company were very helpful and spent lots of time with us answering our questions before we actually placed our order. They were very efficient with the installation process and we would recommend them. Competitive price too.

  • 5 star review  We recently had a new front door and windows fitted. Very efficient service from start to finish with everyone extremely helpful. The fitter was very careful especially bearing in mind it was raining on the day of fitting. Would definitely recommend.
