Plumbing
Commercial and industrial maintenance, drainage and underground services, CCTV and jetting, backflow testing and certification, leak detection, water filtration and gasfitting.
We are a commercial and industrial plumbing contractor based in Coburg North, with over 25 years of experience in the trade. Plumbing, excavation, burst fire service repairs and roofing are all carried out in-house.
We started in 2013 with a broad mix of residential and commercial plumbing. Over the years the work has grown into commercial maintenance, fire services, drainage and excavation, roofing and larger projects, and we have built up the team and the equipment to carry out more of it ourselves.
We work for builders, facility and property managers, asset managers and government, on government housing and facilities, schools, commercial and industrial properties, shopping centres, apartments and strata, and in the Defence sector.

I started out in manufacturing and industrial maintenance plumbing, on sites including Ford and Kenworth and in commercial food production and catering facilities. Those sites had to keep operating while the work was done, and that gave me a grounding in maintenance, fault finding and working around production.
I started Giant Plumbing because I wanted to build my own business and have control over the standard of work we put out.
I’m still closely involved. I quote the work, deal with clients directly and oversee our projects, and I’m hands-on when needed, particularly for investigations or jobs where we have to work out exactly what is going on before we repair it.
Being the biggest plumbing company is not the aim. I want the right equipment to take on difficult work and do more of it ourselves.

We aim to work a problem out and get the job done, rather than do the easy part and pass everything else on.
When we repair a burst pipe or investigate a blockage, we want to understand why it happened and whether another issue will cause trouble again.
We document what we find. If something needs replacing we say so, and if there is a practical repair we give you that option.
Much of what we are called for is not straightforward: an underground fire service leak, a drainage problem nobody has been able to resolve, a difficult roof leak, or a job that needs excavation, concrete and plumbing together.
