Overall, we enjoyed our experience with Treumann very much. It was a pleasure to work with Treumann. During our renovation, Zihni has exceled in day-to-day communication, personal advice and availability. The Treumann team has worked very fast and efficient and they finished on schedule. Moreover, they paid attention to the after care when a few issues popped up later and he sent staff to fix some minor issues. One point for improvement is that as a contractor and project manager Zihni could provide a little more oversight of the people working for him as some of his workers showed a lack of attention to details (functionality was considered more important than the asthetics). However, overall we were very satisfied with Treumann and highly recommend him.
