About Us
Auckland's Trusted Water Tank Repair Specialists
A leaking water tank doesn’t mean you need a new one. We fix them from the inside, no digging up the yard, no replacing the whole thing. Inspect the problem, build a custom liner in our Auckland workshop, install it, usually in a day.
Concrete or plastic, home or lifestyle block or commercial site, we’ve likely seen your tank before. Every liner job comes with a full clean, and most tanks have water back in them by the end of the day we’re on site.
Over 1,000 water tanks fixed across Auckland in the last six years. Most of our work still comes from word of mouth, not ads, which tells you something about how the jobs go. You get a straight answer on what the tank needs and a fixed price before anyone picks up a tool.

Water Tank Repair Specialists in Auckland
We fix water tanks from the inside. Our team inspects the tank, fabricates a custom liner in our Auckland workshop, and installs it on site, usually in a single day. It works on concrete and plastic tanks, across residential, rural, and commercial properties.
We also handle plastic tank installs and full tank cleans, which come standard with every liner job. Whether it’s a slow, unexplained drop in your water level or a crack you’ve been patching for years, we find out where the water’s actually going before we quote anything.
Over 1,000 water tanks fixed across Auckland in the past six years, mostly through word of mouth rather than advertising. Every job gets a fixed price before we start, and most standard tanks have water back in them the same day.

Frequently Asked Questions
Got a leaking water tank and a few questions before you book? Fair enough. Most people want to know what a repair actually costs, how long it takes, and whether their tank can be fixed or needs replacing altogether.
Below are answers to what we hear most, on pricing, turnaround, and what’s involved in relining a concrete or plastic tank. Still got a question? Get a free instant quote and ask us directly, we’ll give you a straight answer.
How much does it cost to fix a leaking water tank?
Every water tank's different, so there's no flat price without seeing it first. Once we've inspected it, you get a clear, fixed price before any work starts. No surprises once we're on site.
How long does a water tank reline take?
Most standard tanks are done in a single day, inspection, reline, and refill. If your tank's bigger or the damage's more involved, we'll tell you the exact timeframe during the inspection.
Do you fix concrete tanks, plastic tanks, or both?
Both. We repair and reline concrete and plastic water tanks, and we handle plastic tank installs too, right across Auckland.
Will I be without water while the tank's being fixed?
Usually not for long. Most standard tanks have water back in them the same day the job's finished, so you're not left without supply for days.
How do you find out where the leak actually is?
We inspect the tank inside and out on site. A lot of people have no idea where the water's going, that's exactly what the inspection is for, before we recommend anything.
My tank just needs cleaning, not fixing, can you help?
Cleaning alone isn't our main focus, we specialise in fixing leaks and cracks. That said, every liner job includes a full tank clean as standard, so if there's a leak involved, it's sorted at the same time.
Do you install brand new water tanks?
We install new plastic water tanks. For concrete tanks, our focus is repair and relining rather than new installs.
What areas do you service?
We're based in Auckland and cover the wider region, including Whangaparāoa, Beachlands, and the Warkworth belt. We also take jobs further out in Northland and the Coromandel when they line up with other work nearby.
