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!

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.
