Jason Keating

I couldn’t recommend Mander & Co Ltd any more highly. I was referred to Mander & Co Ltd by a sparky helping me find a short that kept shutting down power to my kitchen on a Sunday morning. It turned out my Rinnai had sprung a leak and was tripping the RCD – no hot water in a house of 6 – not fun. The sparky recommended Mander & Co Ltd, in fact, he texted my details to Mander & Co Ltd on the Sunday and said I should expect to hear from them first thing in the morning. That’s exactly what happened and within about 24 hours the team from Mander & Co Ltd called me they were on site and replacing my Rinnai. I got awesome advice about my entire gas setup including pressure, the gas meter and my pipes. They even volunteered to talk to my gas supplier for me. Within no time we had hot water again, and as a result of talking to my gas supplier they got my meter replaced and pressure sorted at no cost to me. Add to that they knew more about the pipe diameter and pressure and new regulations than the gas supplier and they also saved me from having to pay thousands for replacing all the gas pipes. An awesome job!

My husband Merv Cronin, a retired builder, has just finished a toilet and laundry conversion into an accessible wheelchair shower room for my sister in Johnsonville. We live in Christchurch and picked Mander & Co Ltd as the plumbers. From the first meeting with Gavin, we were impressed with his professionalism and knowledge. The plumbers assigned to the job by Mander & Co Ltd were a delight to work with. Nothing was a problem from organising other subcontractors ie stopper and painter to carrying out his own plumbing work. The whole job went seamlessly and was finished on time in no small part due to Gavin’s team. We would thoroughly recommend Mander & Co Ltd and want to thank them for making the job a good experience for my husband and my sister Valerie.


I would also like to take this opportunity to thank George and Richard for the fantastic job they did for us recently in removing black Quest pipe from our house. Due to the design of our house, it was a very difficult job but they achieved it in good time and with such minimal intrusion into the structure it is now difficult to tell they had been here at all! Great job ! Would totally recommend them, difficult jobs are obviously their speciality. 
Best Regards 

Hello Boss

I want to let you know that the work that was done at the salon this week was done extremely well. Not only did you send Phil almost straight away Stewart also did a great job as a plumber/builder. They were both very understanding and considerate in keeping the salon running. Top marks. Thank you 
Cheers David.

We have dealt with Mander & Co Ltd for over 20 years for various plumbing jobs and gas work, and have always had exemplary service. Facing the daunting prospect of major renovations (including replacing Dux Quest piping, renovating two bathrooms, installing a new kitchen, re-carpeting, new gas heating and hot water system, and a whole-house repaint) we asked Gavin Chambers to project manage the work for us. Gavin arranged everything, including employing top quality tradespeople and scheduling the work to get it completed in the shortest possible time. Barry (builder), Terry (painter), Phil (electrician), John/BTS (tiler), Raymond (carpet & vinyl), and the teams at Plumbing World and Mastercraft Kitchens couldn’t have been more helpful or professional. 

Gavin made some excellent suggestions along the way and ensured the inevitable unforeseen issues that arise with such a major renovation did not hold up progress. The Tradesman who was our day-to-day contact and his onsite management and coordination of the trades were also top-notch. We were kept fully informed throughout, any questions we had were answered quickly and efficiently. Any extras were explained and cost before the work was done. 
We wanted to do it once, and do it right, and that is the outcome Gavin and Mander & Co Ltd delivered. We couldn’t be happier with the final result; the quality is superb, and the work was completed on time and on budget. We have no hesitation in recommending Gavin and the team at Mander & Co Ltd to anyone who appreciates responsiveness, quality, and reliability.
