Conservatories- 14 Jun 2026
Wow, Xavia and his crew have done an amazing job replacing old polycarbonate conservatory roof with a solid tiled, insulated warm roof. I couldn't recommend these people enough, clean, curious, and experts in my opinion at all that they do. They went over and above when the weather changed to unforeseen heavy rain, and made sure we were watertight throughout. Lovely people, wonderful job, the best tradesmen I've met on my 64 years on this planet. Thank you.

Extensions- 25 Apr 2018
Initially when using My Builder, I didn’t really have any intentions of working with tradesmen from here, it was more to benchmark and see where a quotation would be priced however upon meeting Vijay, that pretty much changed from the first meeting. If you’re looking for someone who treats your project like their own, he’s the man. Vijay takes 110% pride and care into every aspect of your project. Although work is yet to commence on my property, the spec Vijay has put together itself is worth a lot of money, and most would consider it invaluable. From my opinion so far, no stone will be left unturned where Vijay’s project management and work is concerned. Without thinking twice, I would highly recommend anyone considering Vijay, to at the very least, meet with him and show him the work required. From there on, your mind will be made up. Looking forward to working with him in due course

Extensions- 2 May 2018
Tom is a very competent builder, who has attention to details. Tom continuously went out of his way to find ways to meet my requirements, Whenever we had atypical challenge during my extension Tom's default position was "let's find a work around." He was creative and efficient in doing so, and most importantly cost effective, as I was running on tight budget. Fantastic experience working with Tom, he estimated the work to complete in 6 weeks, the work was done 5 and a half weeks and handed over. The works speaks of itself, very urban finish with high level of professionalism. I was almost hands off the project due to work travel, and Tom took care of all the aspects without me being involved day to day and micro manage. He is surely being to be big league builder in no time. I would recommend him whole heartedly.

Extensions- 12 Jul 2021
Great company. Came round on a Sunday to look at the job and quote and were so totally honest, they told us they didn't think anything was required! They left a quote if we wanted them to take up the floor and explore further what we thought the issue was but said, in their opinion, nothing was required. How refreshingly honest. Great guys, great experience, thank you so much

Edmond did stellar work on the full kitchen renovation of our central London flat, and I can't recommend him highly enough. His professionalism, expertise, and attention to detail are on another level, and he is an excellent communicator. The end result was meticulous; he worked efficiently within the agreed timelines while resolving unexpected challenges and providing solid guidance throughout the project. Edmond also has a strong network of professionals who were just as reliable and easy to work with as he is. We also appreciated how tidy our home was left every day and how well all areas were protected during the build.

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!
