Family-owned plumbing, drainlaying and gas fitting business based in Karaka, South Auckland. Run by Louis Du Preez - certified plumber, drainlayer and gas fitter. Working across all of Auckland with a small, hands-on team and a 6-month workmanship guarantee on every job.
Louis Du Preez - Owner, Plumb-D Tec
Louis qualified as a Red Seal plumber in South Africa and spent more than a decade running residential and commercial jobs there before relocating to New Zealand in 2019.
Rather than lean on the qualification he already had, he re-qualified under NZ standards from the ground up - certified plumber, certified drainlayer, and registered gas fitter under PGDB.
That's the short version. The reason it matters: full NZ certification across all three trades takes years, and most plumbers stop at one. Louis went through it because he wanted to be the one who handled the whole job - the plumbing, the drainage, the gas - instead of booking in a second tradie every time the work crossed a discipline.
He's known on jobs for practical, "think outside the box" diagnostic work. The customers who keep calling back are the ones with the awkward problems - the persistent bathroom smell no one else could trace, the high water bill with no visible leak, the cylinder install that needed pipework routed through a tricky part of an older house. Specialist filtration work is a particular focus.
Three people work the day-to-day. The small-team setup is deliberate. Every job runs through Louis or Connor - there's no project manager between you and the people doing the work, and you're not handed off to a new face each time you call. The plumber who quoted your job is the plumber on the tools.

Quote first, work second. The number we send is the number that holds, even when something unexpected turns up mid-job. Mickle Fyfe's review on the homepage spells it out: "they stick to quoted price even though we had a few little curveballs."
Most of our work comes from repeat customers and their referrals. We'd rather earn a tenth callout than win a one-off. The phone gets answered, the job gets followed up, the certificate gets emailed.
Louis's words. Every job carries our 6-month workmanship guarantee, and every gas job carries the safety certificate to match.
Real feedback from Auckland homeowners. Not a word changed.
