Great new quality windows at very reasonable cost, efficiently and professionally installed

I rarely write online reviews but decided to do so in this case, given the excellent experience with SDG. Vic and all his colleagues were friendly, knowledgeable, professional and efficient throughout, from measuring, quoting and ordering to installation and clear-up. Having discussed available options, I chose UPVC with "wood grain effect" for new windows on the ground floor to replace 2 tired, old UPVC windows and I am so pleased with the results. Installation only took about 3 hours, which was less time than I'd expected, with minimal disruption/noise. The new windows from SDG are a perfect match with the existing wooden windows on the floor above and with those in the adjoining properties on the terrace, enhancing the "kerb appeal" of my flat immensely as a result. SDG's windows are very good value for money and I won't hesitate to use their products and services again when I need to replace other windows in my property. I highly recommend the entire team at SDG!

Replacement Glass in Conservatory Double Glazed Door

I had a shattered glass pane in my double glazed conservatory door. I sent SDG Windows some photos and they gave me a quote and came promptly to check and measure. A few days later they installed the new glass within the existing door frame. They did a good job at a reasonable price and I would use SDG again for relevant work.

Bay window replacement

This was the best experience I could have had. I wasn't sure if I needed my bay windows replaced completely (there are six panels), and SDG were very honest in their suggestions and what my options were. In the end I decided to replace all windows due to the fact they were old and the price was good. I went with UPVC which is what I had before anyway, but these were an upgrade. Vick was great at corresponding, and him and his team were very professional, extremely punctual, and tidy during the whole process of replacing the windows (which was only about 3hrs). I would happily use them again and gladly recommend them to anyone. Also, I had another company come to provide a quote and window options, and it was more or less exactly the same. So I feel I got good value for money and for the awesome job done and quality of the windows. Thank you Vick and team! - Dina H
