Slimline steel replacement windows & doors

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

METICULOUS ATTENTION TO DETAIL

Our aluminium slimline steel replacement windows and doors are crafted to perfectly emulate the timeless appeal of traditional steel windows and “crittal” style windows (Please note that we do not supply the Crittall brand). Meticulously designed with a keen attention to detail, our windows and doors are so well-crafted that it’s difficult to distinguish them from steel windows. Our slimline steel replacement windows feature joints that closely resemble those found on traditional steel windows, further showcasing the exceptional craftsmanship that goes into their production.

Our slimline aluminium steel replacement doors and windows are extremely popular due to their ability to replicate the sleek look of some traditional steel windows while still maintaining the charm of your original heritage windows. We even offer french door styles that can be replicated to complement your existing aesthetic. Our steel replacement windows and doors can be used both externally and internally, making them a versatile and elegant choice for any property.

  • 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.

  • If you've ever built a house you'll appreciate how hit and miss glass contractors can be, but The Window Sanctuary stand out as reliable, good quality and easy to deal with. The guys turned up on time, worked really hard and did a fantastic job. I wouldn't hesitate to recommend this company.

  • I cannot recommend “The Window Sanctuary “ enough. We have a very modern property with large expanses of glass, Aluminium frames were advised and were very competitively priced. The level of customer service was exceptional throughout, the installation process caused minimal disruption and the finished windows and Bi-fold doors look fantastic

  • 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.
