Reiner was a great help in getting helping us think through a major job of underpinning our basement then refinishing it. We had previously renovated upstairs and the experience of trying to manage the contractor who worked at his own pace had left my wife and me mentally fatigued, so we turned to Reiner for this second phase of the renovation. We are very happy that we did so!
He gave us very good advice and patiently explained trade-offs. He helped us select contractors and finalize contracts (including delay penalties!). Once the job started he was great at managing them and making sure the work was up to his high expectations and relatively on track. I also believe that with his sourcing and management of the contractors we saved more money than we spent on his fees!
I have already recommended him to friends. My one advice would be get Reiner in early (before even talking to architects) as he can then make sure all things are done right from the start and you don't need to back track.
