Latest review:
had an excellent experience working with Cristian on my bathroom project. From start to finish, his work exceeded all expectations. Cristian was professional, attentive to my needs, and incredibly detail-oriented. His craftsmanship and commitment to quality were evident in every aspect of the project, and he transformed the space beautifully. He kept communication clear and made sure everything was completed on time and according to my vision. I am thrilled with the results and highly recommend his services.

Garry and team were very knowledgeable about how the windows should be installed. They managed to retain the Victorian features of the existing windows and were perfectionist when it came to finishing each window. I am very happy with my windows and would highly recommend them.

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.
