Mario was absolutely amazing to work with. He was always fully transparent, honest, provided a range of options with what the pros and cons of each option would be, and was willing to think flexibly about how to best waterproof our basement and be efficient in terms of time and money spent. His team was was reliable, professional, and incredibly hardworking. The work was messy but they cleaned up perfectly. During the process they also discovered additional unfortunate problems with the foundation (no fault of their own) and they worked to fix it quickly without any hassle. I have already recommended him to four people.
