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.

Bathroom Fitting- 26 Jul 2024
Catalin completely transformed both bathrooms! He listened to our requests and has come with good solutions to our problems, including recessed shelves and replacing the hot water cylinder with a combi boiler, to give us more space in the bathroom. The work was done to a very high standard and has helped us to source materials and sanitary ware. Catalin and his team has done a fabulous job! I highly recommend him!
