Worked with this contractor company for the renovations of my office and found their service efficient and hassle-free. Alvin, the consultant we worked with was very helpful and responsive when we met several difficulties. Even though the renovation project was estimated to be completed in less than a week, it stretched to almost two weeks. Fortunately, Alvin was very accommodating and spared us extra manpower when we needed them to complete the work more quickly. The workers that were deployed to our office were mostly hardworking and disciplined, and were willing to work longer hours when necessary. Concept’s prices are pretty competitive in the market and they’re up for negotiations if you find their prices too steep.
