15 years of getting it right

Who you're dealing with

Flush & Flow Plumbing & Gas is a family owned and operated business, run by Jorden Clark, a certifying plumber and gasfitter with over 15 years of hands-on experience across Christchurch homes and properties. We're based in St Martins, and we work right across the city — from the hill suburbs through the central belt and out to Rolleston.

The business is family owned and deliberately small. That means when you ring, you get someone who knows the job, and when we quote a price, that's the price. We take on work of most sizes, from a dripping tap through to a full gas conversion, and the site gets left as clean as we found it.

What "certifying" means, and why it matters

All plumbing, gasfitting and drainlaying work in New Zealand is regulated by the Plumbers, Gasfitters and Drainlayers Board. Most plumbing and drainlaying work — and all gasfitting work — has to be carried out by someone registered with the Board.

A certifying tradesperson sits at the top of that structure: authorised to work unsupervised and to certify their own work. For you, it means the person who does the job also signs it off, so there's no waiting on a third party for paperwork and no gaps in who's responsible for what.

Using an unlicensed tradesperson means the work is being done unlawfully, and it can leave you with no insurance cover, no legal protection, and no assurance the job was done safely. We'd encourage you to check anyone you hire on the PGDB public register — including us.

Our 12-month workmanship guarantee

New installations we carry out are guaranteed for 12 months from the day the work is completed or delivered. If something we installed isn't right because of how we did it, we come back and put it right at no charge to you.

• What it covers: newly constructed or installed work, such as a new hot water cylinder, gas hob or fire, bathroom or kitchen plumbing, or new pipework. It covers our workmanship, and it covers the materials too, but only where we supplied them.
• What it doesn't cover: standard maintenance and repair work; drain clearing; work on existing roofs, such as flashings and fittings around vents and flues; bench-mounted taps and mixers fitted to solid timber or custom wooden benchtops, where the tap works loose because the timber compresses, shrinks or moves over time; and appliances or materials you supply yourself, which carry the manufacturer's or supplier's own warranty.

Nothing here limits your rights under the Consumer Guarantees Act 1993. The full wording is in our terms of use.

How we work

• Free quotes across Christchurch, and the quote is the price. No surprises added at the end.
• Published rates. Our full rate card is on the site — standard, after-hours and public holiday. Very few trades do this. We'd rather you knew going in.
• We answer the phone. Including at night. One of our Google reviews is from a household who rang five gasfitters about a weekend gas leak and got exactly one call back.
• Clean site. Drop sheets down, mess taken away, the place left the way we found it.
• Straight advice. Including when the honest answer is that a repair isn't worth doing, or that the problem isn't ours to fix.

What we're known for

Gas, mostly. If you look at what customers actually mention in our reviews, the words that come up again and again are gas hob repairs, gas hot water conversions and gas fitting. That's the work we do most of and the work people come back for — though the general plumbing, drains and hot water side is just as much a part of the day.

We're rated 5.0 on Google with 115+ five-star reviews, and 5.0 on Builderscrack, and we'd rather you read those than take our word for any of this.

Trade suppliers

We buy through Mico and Plumbing World, which means genuine parts, manufacturer warranties that actually stand up, and one point of contact if something needs to go back.
