I hired Advanced Plumbing half-way through our 2-floor renovation, and my only regret is not hiring them from the start! It is so refreshing to find a company like this. These guys are knowledgeable, professional, efficient, courteous, and friendly. They showed up on time and followed up by phone and email up when necessary (unheard of in Toronto!) Never did I feel like I was left hanging. Right from the first meeting with Owner Greg, it was a pleasure to work with this team. When George and Tenzin showed up to do the work, they took the time to review the project with me and to flag any problem areas. They discovered some rather unfortunate issues with the rough-in done by a previous plumber, and patiently and thoroughly explained my options to me. We sorted it out and now we have two beautifully functioning bathrooms. I have nothing but great things to say. 5 stars all they way - rock stars!
