We had Jiangs refinish our entire staircase (which was previously carpeted) and renovate the basement, which was poorly done by the previous contractors/homeowners. Evan, the main contractor was very responsive and easy to deal with. He provided us with a very fair estimate and was very mindful about our requests. These guys are busy, so we had to wait several weeks before they were able to start.
His team are very hardworking individuals and overall, we were satisfied with the job. What we think needs some fine tuning, are their finishing touches to the finer details - It sort of felt like some of the renovation was rushed (Had overspray of paint onto another accent wall, trim pieces weren't perfect and some aesthetic decisions were questionable).
However, all things considered we were happy with the finished result as they did fix most of what we had pointed out and we mostly got what we originally wanted. I would recommend these guys especially based on price and the speed at which they worked at. I do appreciate that Evan himself seems like he cares about the job and wants to make sure his clients are happy.
