 Trustindex verifies that the original source of the review is Google.  Called in tears over a leak from upstairs into our bedroom, and they were able to send someone out the same day. He located the issue and fixed it straightaway, with a pleasant demeanour, honest explanation, and leaving the place tidier even than he found it. I would recommend Harbour City Plumbing & Gasfitting to anyone.

 Trustindex verifies that the original source of the review is Google.  Brad and his team were extremely efficient and highly professional. They completed the pipeline project (installing a sewer pipe) fast and to a high standard, passing the Council's inspection on the same day it was completed. Brad had a comprehensive understanding of the work, and his approach proved he could achieve maximum results with minimal investment. My communication with Brad and his team (especially foreman Famausili) was very smooth, and I would choose them again in the future. I highly recommend Brad and Harbour City Plumbing & Gasfitting Ltd.

 Trustindex verifies that the original source of the review is Google.  Harbour City Plumbing were fantastic to deal with. Glen installed a new kitchen faucet, fixed a leak in the shower, and replaced a faulty plug in the bathroom sink - all done quickly and to a really high standard. His communication was excellent throughout, and he came prepared with a great range of options which meant he could do the work in one visit. Really impressed with the quality of the work and the professionalism. Highly recommend!
