Bricklaying- 14 Apr 2026
Prior to starting the job, Shefit was very responsive to my emails and WhatsApp messages and was very easy to communicate with. I left Shefit detailed instructions of where to position the walls we wanted constructing for our small extension as I was not going to be there when he arrived. I returned later that afternoon to find the job well under way - he had even sent me a short video of the work in progress - yo find everything had been done as per my instructions. The team worked all day and finished the job in about 8 hours - hardly stopping for a break it seems and refusing any attempt by my wife to ply them with coffee and tea. They left the site clean and tidy were incredibly polite and respectful - one of them even asking if they could use the toilet, which of course they could! I would recommend Shefit and his team wholeheartedly. The price was reasonable and the job was done quickly and cleanly.

Latest review:
Firoj and his team renovated a bathroom for me in March 2015. He gave me a fixed cost for his labour and what turned out to be a very accurate estimated cost for all the parts/materials at the outset. He also gave me a completion time of 9 days with 1 extra day for 'spillovers' and 'unforseen delays'. He finished the job at exactly 9 days and still came around on the 10th day to see how everything was working. The quality of his work was excellent, to say the least. He attention to detail was admirable, as was his commitment to delivering a finished product that would last several years. This focus on detail and longevity is something that really sets Firoj apart from other builders, who often see such jobs as just another task to be completed before moving onto the next job. I have no hesitation in recommending him. Several months later my bathroom still looks great and everything works.
