My hot water system broke down, and this company was suggested to me. Within two minutes of speaking with them, I received an exceptionally reasonable and competitive price quote. They were comforting and courteous, setting up for the new hot water system to be supplied the following morning and for two plumbers to arrive on the job site later that afternoon. It was installed and ready to use in three hours. I cannot express how highly I suggest EZI Plumbing, and they will now always be my first port of call. I'm grateful.
