Testimonials

What Our Clients Say

I was delighted by the professional, efficient and friendly service for installing secondary glazing in my Grade 2 listed flat. Everyone I met, including the installation chaps, was 100% in terms of advice and calibre of work completed. I would warmly recommend them to everyone. 👏👏👏⭐️⭐️⭐️

The guys at Legend Glass are amazing! I’m so happy with the work they have done for me. They refurbished my old ikea mirror by putting mirror over the thick wooden frame. The results have exceeded my expectations! My new mirror is just beautiful.

I just wanted to recognize this company for its excellent work. My family and I are completely satisfied with their service, and extremely pleased with the quality of the glass installed on our table top. All their staff were most respectful and diligent at all times. We strongly recommend their services and products.
