Slimline Steel Replacement Windows & Doors

An excellent aluminium replacement for traditional steel windows and doors in a range of colours.

ATTENTION TO DETAIL

Our aluminium slimline steel replacement Windows and Doors are manufactured to replicate the appearance of traditional steel windows and “crittal” style windows. (Please note we do not supply the Crittall brand). Beautifully designed with close attention to detail ensures that you would be hard pressed to notice the difference from steel windows and our aluminium replacements. The likeness to steel windows is accentuated by the similar looking joints which replicate traditional items & demonstrates the attention to detail in the manufacture of our slimline steel replacement windows. 

Our very popular Alitherm slimline aluminium steel replacement doors and windows replicate the sleeker look of some traditional steel windows and retain the traditional style of your original heritage windows – even french door styles can be replicated. Our steel replacement windows and doors can be used externally, or internally as room dividers.

  • 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!

  • 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.

  • Very professional. I have used other window companies before but the service provided by them left much to be desired when compared to Window Santuary. Any snagging problem was promptly sorted out by the management promptly and to our satisfaction. The workers were very punctual, came daily and stopped only when fully finished. I would highly recommend this window company to others.
