Josh Davey22/05/2025Trustindex verifies that the original source of the review is Google. Called these guys during a kitchen emergency at my restaurant. They were fast but also efficient and more importantly trustworthy with their workmanship and took the time to explain a couple of product replacement items. Highly recommended. karen Englert02/05/2025Trustindex verifies that the original source of the review is Google. I was very impressed with the service Liam gave us. We have had a leak under our house for quite a while. Liam found it and fixed it. He is an absolute asset to the company. He was very professional, courteous, polite and kept us fully informed what was happening and even went the extra mile. Thoroughly recommend this business and Liam.

Netball Wellington Centre18/02/2025Trustindex verifies that the original source of the review is Google. Brad and the team at Harbour City Plumbing and Gasfitting are the best. They are only a phone call away, they guide you on the best remedial action, they are friendly, and the job is completed efficiently and effectively. Highly recommend them for personal and business repairs. Richard Rees10/02/2025Trustindex verifies that the original source of the review is Google. Friendly, fast and efficient. They call back when they say they will and they do what they promise. Glen was a pleasure to have on site. He knew his stuff, was positive and proactive. I would highly recommend Harbour City Plumbing and the way I got onto them is they were recommended! Danielle Ryan29/01/2025Trustindex verifies that the original source of the review is Google. We discovered wet carpet in a wardrobe that backed onto our main bathroom. Glen from Harbour City was so great to deal with. Excellent communication around his arrival time, checked all the basics in our bathroom before determining that the issue likely lay with the jets in the spa bath. This meant cutting a hole in the back wall of the wardrobe (as no access panel had been built in) and he found and fixed the issue immediately. He then diligently popped the gib back in and screwed it tidily. He also took away all rubbish and vacuumed the site to leave everything looking really tidy. The invoice was promptly sent and I appreciated that he'd taken photos along the way of the issue and the work he'd done - these were shared with us alongside the invoice. I highly recommend. Rakesh Patel03/01/2025Trustindex verifies that the original source of the review is Google. I'm lost for words, the toilet was blocked, a call to this amazing team, within 30 mins on a public holiday they where here and did there magic, will recommend there services to my friends and family, thank you for your help Alister Stubbe10/12/2024Trustindex verifies that the original source of the review is Google. This is a slightly odd review, since I haven't worked with Harbor City Plumbing and Gasfitting myself. Instead, my neighbor brought them in to work on a job in Johnsonville. It was a narrow street right next to a dead end, so certainly not an easy place to bring in a bunch of trucks, but they got the work done with relatively little disruption. What sets them apart though (and motivated me to write this review) was that after finishing up, there was a small sandbag left behind - nothing major or anything, and easy enough to miss. After calling Brad, he immediately said he'd get that sorted ASAP, and was incredibly friendly. It's awesome to see a company that'll happily work with the neighbors like this! Will Murray29/11/2024Trustindex verifies that the original source of the review is Google. Really happy with the prompt efficient assistance from Harbour City Plumbing. It was great to have the blocked pipes sorted, and to have a friendly professional onsite who was happy to not only sort out but also explain the issues. Jess Pleasants05/11/2024Trustindex verifies that the original source of the review is Google. Called late one night stressed as I needed a washing machine disconnected after we couldn’t turn the water valve off and needed to be gone by 10am the next morning, Brad answered and said he would have someone out first thing in the morning, didn’t catch his name but he was on time friendly and got the job done quick and efficiently didn’t muck around to get more money which some do, great staff highly recommend
