Why SNZ

The differences you notice once you work with us.

We would rather show you than tell you. But if you are deciding who to trust with a tender, here is what actually sets us apart, plainly.

Rates that move the day the market moves

Most estimates are priced off rate books or subscription data sets that update on a schedule, sometimes once a year. Between updates, the numbers are simply out of date, and no one using them knows by how much.

When conflict in the Middle East recently pushed PVC up around 32% and HDPE close to 40%, the next estimate that left our office carried the revised rates the same day, not at the next quarterly update.

We hold live, real market rates and we adjust them the moment the market does. On a tender, the difference between a current rate and a twelve-month-old one is the difference between a bid that holds and a bid that bleeds.

Specialists, not a side business

Hydraulic, plumbing and stormwater estimating is not one of twenty things we do. It is the only thing we do.

We are not a generalist firm that also prices plumbing. Every hour of our week is spent on hydraulic scope, which is why we read it faster and price it more accurately than a firm splitting attention across every trade. When plumbing is the whole business, the detail that generalists gloss over is the detail we live in.

Real people, in a real Sydney office

You can sit across the table from the estimator who priced your job.

We are based in Bankstown, Sydney. Not a virtual presence, not a name on a website. You are welcome to bring your drawings and your printed estimate to our office, have a coffee, and we will walk you through every line, where each dollar came from and why. You deal with a real person you can reach, here, in Australia.

Australian standards, understood

We work to AS/NZS 3500 and the relevant authority specifications every day. We know Australian builders, Australian plumbers and what they actually need.

Here, not somewhere unknown

We live and work in Sydney. You can call us, meet us and visit us. The people pricing your tender are the people you can talk to.

We check every estimate before it leaves

Every estimate is independently reviewed before it reaches you. We will not skip that, even under deadline pressure.

Occasionally a contractor needs a full estimate turned around in a day, and our quality process does not allow us to cut that corner. We would rather be honest about our timeline than hand over a number that has not been properly checked. On a tender worth winning, the checked number is the one you want.

The only subscription estimating model of its kind

For contractors pricing consistently, we offer ongoing estimating on subscription, shaped around your pipeline rather than sold as a fixed box. It is a model no one else in Australian plumbing estimating runs, and it means expert estimating on tap without the overhead of a full-time hire. See how the subscription works.
