I have use Tai Irwin for a number of years. They are knowledgeable, customer-focused, reliable, professional and do top class work in a very time efficient manner. They also provide advice to their customers about things that are not necessarily well known. I recently had a concealed water leak. Not only did Tai Irwin organise for Jamie to come to assist me very quickly, Jamie then organised for the location of my leak to be diagnosed in the most efficient manner, immediately then fixed my leak and provided me with advice about how I could approach Sydney Water to take the concealed leak into account when assessing my water bill. A huge thank you Jamie for your work and your advice which lead to sydney water reducing the significant increase in my water bill by 50%.
