Overview
Independent plumbing compliance and inspection reporting.
GemArk Consultancy helps Brisbane property owners, buyers, managers and commercial sites understand plumbing risk before it becomes an expensive problem. The focus is clear inspection, practical reporting and compliance-minded advice — backed by over 15 years of industry experience.
Why this matters right now
Australia's housing boom is hiding a plumbing compliance problem.
Queensland is in the middle of a housing shortage and a construction surge. To keep up with demand, the industry has drawn on a large number of overseas-trained tradespeople, and not all of that work is meeting Australian standards. At the same time, under-resourced council inspection systems mean non-compliant and substandard plumbing can pass through without being caught.
The result: Brisbane buyers are purchasing homes and investment properties with illegal, non-compliant or outright failing plumbing installed inside walls, under slabs and underground — work that no standard building and pest inspection is scoped to find.
GemArk provides the independent plumbing scrutiny that sits outside the standard building and pest scope. If the work is wrong, we want to find it before you buy.

What building and pest inspections can miss about plumbing.
Building and pest inspections cover what they are scoped to cover. Plumbing systems — particularly drainage, stormwater, underground pipework and compliance of installed work — often require a separate, plumbing-specific inspection. In the current construction environment, that gap is more important than ever.

What clients say about GemArk.
"We engaged GemArk Consultancy for a pre-handover plumbing inspection on our new build. The inspection identified issues with drainage and hot water installation that we were able to raise before settlement. Professional, factual and well documented."
— Dennis Chesterfield
"As a first-time buyer, I honestly had no idea how much plumbing risk sits underground. The report itself was detailed but written in plain English. It didn't feel alarmist or dramatic, just factual and practical."
— Susan Branch
"We engaged GemArk Consultancy for our annual RPZ backflow testing in Brisbane. They were extremely thorough, professional, and clearly explained the compliance requirements."
