Why choose us
Why choose SDJ Plumbing and Gas Pty Ltd as your Mandurah plumber.
We’re a Mandurah-based plumbing operation focused on residential maintenance and gas work. Every job is done to Building and Energy WA Plumbers Licensing Board compliance standards and certified on completion. Plumbing isn’t supposed to be a mystery — we tell you what’s wrong, what it’ll cost to fix, and what the timing looks like, before any tool comes out.
Whether the work is a $90 dripping tap or a full bathroom re-plumb, the standard is the same. Fixed-price quote up front. Compliance certificate where required. Workmanship warranty per Australian plumbing regulation.
We don’t push services you don’t need. If the right answer is a $30 part, that’s the quote. If the right answer is a full system replacement, you’ll see why — and have the option to take the quote elsewhere if you’d like a second opinion.

What makes us different
Different from other Mandurah plumbers.
Most plumbing companies operate through a call centre. You phone, a stranger takes a job ticket, someone else turns up. That model can work for big-volume operations — it doesn’t work when you actually need someone who’s seen your job before.
Our model is simpler. The phone gets answered by the same team that does the work. The plumber who comes out today knows what was on the truck yesterday. Notes get kept. Photos get filed. Continuity matters when the bathroom you fixed last year develops a related issue this year.
Pricing is straightforward — quote first, fix second. We won’t start work until you’ve seen the price. We won’t bill you for parts you didn’t agree to. And if a repair turns out to be unfeasible mid-job, we tell you immediately, not after the bill is bigger.
