Our landlord had our rental property's windows upgraded recently from single pane windows to double glazing, by SDG Windows. The difference to noise pollution, heat loss, and energy saving is immense. The team arrived bang on-time and worked hard, non-stop for four hours to change the four windows in our flat. Their attention to detail was faultless and they tidied up as they went. The senior member of the team was friendly and chatted us through the working of the windows and locks etc. We are very happy with the results.
We needed a new bathroom window installed quickly. We chose SDG Windows because of the fantastic reviews we had seen. The service was brilliant! The window was installed within a week of our enquiry and the team did a great job. Highly recommend!!
Very happy with the communication, installation and quality of the bathroom windows we recently replaced ! Highly recommended
I fully recommend Vic and his team. The windows are well made and they did a fine job fitting them.
We had all the windows in our house replaced. Vic and his team were all very professional and efficient. We are very pleased with our windows. Great quality and reasonably priced. Would recommend!
Fantastic people. I was looking to find a company that could replace some windows in my elderly aunts flat. I contacted Vic at SDG windows and from the very first email the communication was first class. They arrived on time to do the installation and the quality of their work was excellent and they were so clean and tidy. A big thank you to the team at SDG.
Having read the reviews, I first used SDG for one window whilst renovating the kitchen of my Victorian terrace. I wanted high end UPVC sashes, as close to looking like wood as I could get. Vic was great from the start and chatted through all the options. I was so pleased with the result that I ended up using SDG to replace the rest of the windows in the house. The result was exactly what I wanted, with the finish on them so good that the decorator was certain they were wood. I've gone on to recommend SDG to several neighbours in my street, all of whom are equally delighted. Vic, Shaki and their team are highly skilled and a pleasure to deal with, the product was perfect and the price was very reasonable. I would wholeheartedly recommend SDG in a heartbeat - they're a real asset to the area.
