This company never disappoint. I've used them several times for clogs, drain work, Backflow water valve. They have been professional, clear explanation of work, tidy and very courteous. Special mention must go out to Raymond Wong. He has serviced my house on several occasions. He is the epitomy of professionalism, he really cares about doing the job right and always makes clear the different options before proceeding. My wife and I also appreciated the extra care he takes in tidying up the job sight once he's done. Other technicians I have dealt with are also reliable. I would not hesitate to recommend New Canadians Drain and plumbing to family and friends, in fact I already have.
