Extensions- 8 Dec 2023
I recently had the pleasure of accepting Jagdeep on a substantial renovation project. Initially, I was a bit apprehensive as there were no existing reviews to gauge his work. However, after seeing some of his previous projects, I decided to take a leap of faith - and it turned out to be the best decision I've ever made. Jagdeep's approach to our project, which started merely as a rear extension and shower room, was nothing short of exceptional. His remarkable craftsmanship and attention to detail soon convinced me and my wife to extend the scope to a full renovation. Throughout the process, Jagdeep and his team displayed an extraordinary level of skill, professionalism, hard work as well as trust (very rare these days). No task was too challenging, and his willingness to prioritise our needs and provide thoughtful advice was truly comforting. It's rare to find a builder with such dedication and expertise. Jagdeep is undoubtedly one of the best builders I have encountered. My heartfelt thanks to Jagdeep and his team for their outstanding work. Rest assured, for any future projects, he will be the first person I call. Thank you, Jagdeep, for turning our vision into reality, which more than exceeded our expectations!

Extensions- 27 Jul 2023
I would be happy to use RDS buiding services again. They turned up every day worked efficiently and kept the mess created by the construction out of the way of the neighbours. The budget we agreed was followed and the stage payments schedule worked throighout the build. I am very happy with the quality of the work and more importantly the attitude of the builders who worked with us when inevitable snags came along. We invited RDS to do some additional work (landscaping in the garden) which did not detract from the main job. Thanks RDS for a job well done.

Extensions- 26 Sep 2012
Andy and his team did a fantastic job. Our neighbours were very uncooperative and restricted noisy working hours quite severely but Andy was very accomodating. He is very easy to talk to and happy to discuss ideas you may have concerning the build. I would definately reccommend him. We are delighted by the extension and will definately use Andy again in the future. Thanks!
