From the start The Window Sanctuary were friendly and polite and a pleasure to deal with. They offered lots of advice, especially helpful as our installation was a little tricky. We also had lots of issues with our extension which caused delays our end, which The Window Sanctuary worked around, even though it meant the installation had to be carried out in two lots, when initially it was meant to happen in one go - they were very accommodating and patient, thank you! Would definitely recommend.

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.

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 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!

The Window Sanctuary replaced all my old Crittal Windows with slimline heritage aluminium windows to retain the period look of my grade 2 listed property and furthermore replaced the old rotten timber sash windows with new hardwood timber sash windows bringing the property back to life. The guys were hardworking very knowledgeable and very professional I wouldn’t hesitate to recommend this firm highly enough Warm regards Fraser Owen
