Extensions- 22 May 2021
I was left in a mess by cowboy builders. I found Sukhvindsr Singh from mybuilders and then I had nothing to worry about. He completed the project with utmost responsibility from erecting heavy steals to all the way up to finish. I was amazed with the level of his skills and above all honesty. This was a massive 66sqm single storey extension and he put up structure, brickwork, fibreglass roof , underfloor heating , tiling,electric work . He even went beyond our agreement to do bits and pieces to make sure i donot get stressed out. I have given him another job in same property to do patio 88Sqm with porceline tiling. Feature wall prepared by him stood out . Highly recommended and i will be surprised if he does recieve similar feedback in his future jobs.

Kitchen Fitting- 18 Nov 2025
Original timeline stretched a bit due to his other jobs but this was fine. Mario started work early and finished early which suited us. He came to visit and we agreed a price at the start and he stuck to it even when he realised some additional plumbing would be needed. He was honest about some accidental damage. Attention to detail is good and he has all the kit. I would have given 5 stars- he's a proper professional and I enjoyed working with him. 3 stars only because as soon as the work was done he became incommunicado (I messaged a week later to ask how to lift door which had dropped down a few mm on fridge). The warranty advertised is one of the reasons I went with MGB which was £200 more expensive than contenders so this was disappointing. I would have asked him to do my parents' new kitchen too otherwise.
