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.

My partner and I are so pleased with the extension work which Paul & team carried out, not just what was done but also the way it was done. All of the team were great - they turned up when they said they would, and simply got on with their work, They were all polite, friendly, helpful, conscientious, and made several suggestions to improve the finished work. They frequently checked on details with us as the work progressed to ensure that we was satisfied and our needs were met, we was extremely impressed with how they understood & handled our neighbours, will definitely use again in future projects!

Extensions- 25 Aug 2021
Having had bad experiences in the past with other builders, this time we tried to do our homework properly before hiring someone. We couldn't have chosen a more competent and professional builder! We obviously asked around and had many quotes (some ridiculously expensive, others didn't even seem to understand what we wanted to do) but Sorin immediately impressed me with his detailed and fair quote, knowledge and lots of suggestions (he's the kind of guy that immediately gives you the impression that he knows what he's talking about). We encountered some issues during the works (which is to be expected if you didn't build the place yourself) but Sorin and his team did an amazing job and always gave us regular updates. End result? Work completed on time and a new construction that is exactly what we asked for (plus other things here and there that he kindly sorted while he was on site!)
