Dakota
Excellent service from Semtex, the two guys who installed our oven and hooked up the gas for the hobs, left everything clean and tidy - they were really awesome. Quick, efficient, excellent attention to every detail of the installation….. and, really friendly. Highly recommend Semtex Plumbing
Alison
Really happy with the service. Communication was great, they turned up when they said they would, and they found the problem, which the council fixed shortly afterwards. Also it was cheaper than I expected. Thanks Semtex
Ian
Easy to deal with. Job was done in a timely manner. Didn't go over quoted price and left the site tidy.
Stephanie
Very efficient service. Worked out where my water leak was coming from immediately. Wouldn’t hesitate to recommend. Appreciate the good work.
Caroline
Prompt, professional, kept me informed, courteous, worked with a smile, fair price. Highly recommend.
Ed
Quickly turned up to unblock a drain in disgusting, filthy, cramped conditions and were pleasant and cheerful while doing it! The cost was very reasonable for the time and effort they put in. Very happy to recommend this company.
Mary
Best in town I think. Highly recommend!
Desmond
Came early, did a thorough trouble shoot of the issue, listened as symptoms were explained, and solved the problem. Very professional in all respects. Would/will use again.
Rick
Very pleased with the job, as 3 other plumbers said they couldn’t find where the leak was coming from. Looking forward to your help with the next big job.

    Semtex, we are Master Plumbers & Drainlayers!

    In New Zealand, most sanitary plumbing, gasfitting or drainlaying is 'restricted'. That means it's illegal to do it yourself because of the health and safety risks. You also risk expensive mistakes and even voiding your insurance.

    You need to call on the services of an authorised tradesperson. When you use a plumbing firm that is a member of Master Plumbers & Drainlayers, you know they are authorised to carry out the work they do.

    All Master Plumbers & Drainlayers members have a Certifying tradesperson on the team. These people have the highest qualification available and are responsible for making sure the company's work is done competently.
